Websites That Integrate With Buildium: 6 Steps, 2026

The vacancy should leave Buildium once

A website that integrates with Buildium is a rental site or a company site that receives a vacancy from Buildium, or pulls availability and price out of Buildium, so staff do not type the same unit into a second system. The choice in front of you is which of those sites should get the vacancy, not which extra login to collect. Buildium's own syndication page, footer-marked Buildium, A RealPage Company, with a 2026 copyright, names Zillow, Apartments.com, Apartment List, Dwellsy, RentPath, Zumper, and Rental Beast, and the body of that page also names Craigslist plus the website you post from inside Buildium. That page is the list to start from: Buildium rental listing syndication. Dwellsy, RentPath, and Craigslist stay off the priced short list below because a current public price page for each did not load in this research, so no dollar figure is stated for them.

TL;DR: Send the vacancy to a site Buildium already names, pay a published upgrade only when that one vacancy is stuck, and keep a person between the website and any screening charge. If you are still choosing the system that holds the lease, use this Buildium and AppFolio comparison before you buy ads around it. If Buildium itself is the open question, property-management alternatives and DoorLoop set beside Buildium are the comparisons that belong there.

Key Takeaways

• A direct post you type into a rental site and a feed Buildium sends are different products, and they do not share one published price.

• Read the building-size line before you treat an ad as free. A one-to-four-unit home and a larger community are sold differently.

• A listing feed and a fee file are different connections. A site can receive the vacancy and still not receive your fee schedule.

• Keep a person between the website and a screening charge or a signature. The website does not decide who moves in.

• Open API, the connection a review queue needs, is advertised on the Premium plan card. The lower plan cards do not add it in the plan summary.

• Dwellsy, RentPath, and Craigslist are named by Buildium. This guide does not print a price for them.

Who this is for

This is for a property manager or a landlord who already runs Buildium, or is about to, across roughly a small portfolio up to a couple of thousand rentals, and who typed a search because the vacancies need a public website this month. You want to know which sites will take the unit, what you can read on a pricing page, and what you would be buying on a quote. The people doing the work are the leasing seat and the owner who has to explain a slow vacancy. A full-service manager is often paid Management fee range: 8%–12% according to National Center for Housing Management (2026) of collected monthly rent, or a flat fee of roughly $100 to $150 per unit per month, on a page dated October 2, 2026. That fee is the cost of the people. It is not the cost of the website. An empty week still hurts more than a $40 upgrade, which is why the site choice matters, and why a quote with no number is a different kind of decision.

Red flags: You need the listing site to approve the resident or to create the lease with nobody on your staff reviewing the file. Your portfolio is the size, or the association work, that Buildium's pricing page sends to a phone quote instead of the three plan cards, which is a different buying problem from rental websites, covered in association software options. You will not proceed without a dollar figure, and the only site you want is quote-based.

How we evaluated these websites

The weights below are the method for this guide. They are not scores the vendors published, and they are not the result of a test. A pass mark is the lowest reading, on a 1 to 5 scale of the public evidence, that we would want before recommending the site for a given vacancy. A fail mark of 1 means the public record does not support the criterion. We did not award these marks to vendors. The matrix later in the guide records direction and price status only.

Unit type carries 25% because a site that will not take your building cannot fill it. A readable price carries 20% because a quote you cannot see is not yet a decision. The path back into Buildium carries 20% because a listing that dumps strangers into a personal inbox leaves no shared record. Pausing one vacancy carries 15% because a rented unit that stays live creates bad showings. The published size line carries 10% because "free" often stops at a unit count. Separating the listing feed from the fee file carries 10% because managers are now asked to show total monthly cost, and a listing connection does not prove the fees went with it.

Six steps before you connect a site

Work these six steps in order for each website, not once for the whole stack. The point is to stop a feed you cannot explain to an owner.

1. Confirm the name. The site should appear on Buildium's syndication page, or the site's own page should name Buildium. A logo in a slideshow is a weaker record than a sentence that says what moves.

2. Split the direct post from the feed. If you type the listing into the site yourself, use that site's posted price. If Buildium sends it, ask whether the feed has its own contract. Do not copy the self-serve price onto the feed.

3. Match the building. Write down the unit count of the property, then read the site's cutoff for a free package, a call-in package, and a large-community package. A fourplex and a 30-unit building are not the same product.

4. Ask whether fees must travel with the rent. If your market expects a total monthly figure, check the site's fee-file list. A listing destination and a fee integration are two rows, and only one of them may include Buildium.

5. Price the path after the click. The ad is the small number. Screening, a signature, and the plan that includes Open API are the numbers that repeat every lease. Read those on Buildium's pricing page before you add a premium ad.

6. Name the person who may release a screening or a live post. Connect the site only after that name exists. A webhook is a notice. It is not permission to charge an applicant.

A step is done when you can point to the page that supports it. If the page is missing, the step is not done, and the price stays unknown.

What each website actually syncs

The matrix records what the public pages support. "Named" means Buildium's syndication page includes the site. "Pull" means the other company says it reads Buildium. Price status is published, quote-based, or not given as a separate line. Nothing here is a lab result.

For a building of 1 to 4 units, a basic Apartments.com ad includes a Free ad window: 21 days according to Apartments.com (2026), and that page says the ad appears on 6 websites in the Apartments.com network. The same page tells properties with 5 units or more to contact Apartments.com, and it says edits can take up to 2 hours to appear. Paid ads are described as sorting ahead of free listings people submit. The dollar price of Premium on that page varies by state and market, so the upgrade is quote-based.

A listing site still does not decide who may move in. Under this matrix, a proposed design from US Tech Automations would take Applicant.Created as the trigger, read the applicant and account identifiers in the webhook, and write a review record that names the website and the unit. The output is that queue record. A person confirms the unit is still vacant before any screening is ordered and before any applicant email goes out. The prerequisite is Open API, which the Premium plan card adds, plus a callback address your company controls. This is a configuration you could specify. It is not a deployment being reported, and it has no measured savings.

US Tech Automations would also hold a Rental.Updated notice when the rent amount or the contact email is blank, instead of treating the webhook as permission to syndicate. The action is a field check against those blanks. The output is a held row, not a live ad. Staff release the hold. The same prerequisite applies: API access on the Premium plan, and a named person for the release. No resident, no owner, and no time saved is claimed.

Prices you can read, and prices you cannot

Pricing checked October 14, 2026.

Plan floors: $62, $192, and $400 a month according to Buildium (2026), where an incoming bank transfer is $2.35 on the Essential plan, $1.35 on the Growth plan, and $0.60 after the first 12 months on the Premium plan, an outgoing transfer is $0.99, a card payment is 2.99% on each of those plans, an eSign document is $5 on the Essential plan and $1 on the Growth plan, a standard screening report is $17, an enhanced report is $20, an applicant-paid report is $35, inspections on the Essential plan are a $99 setup plus $40 to $95 a month, the Growth plan includes inspection fees and then lists $0.40 per unit after 3 years, an extra business bank account is $99 with 10 included on the Growth plan and 100 included on the Premium plan, readers above 5,000 units and readers pricing community associations are told to call, and the Premium plan card is the one that adds Open API.

A Premium listing on Apartments.com lasts for a Premium term: 30 days according to Apartments.com (2025), the help page claims up to 9 times the search impressions and up to 3 times the leads, and it allows up to 6 videos at 1GB. That help page, updated August 1, 2025, covers properties under 5 units and properties of 5 to 49 units. It still does not print the dollar price. Treat that dollar as quote-based.

Read the third column with the row, not as one unit. For Zillow, 48 hours is the notice before a direct premium window ends, 25 is the community size sent to another advertising path, and 0 bulk tiers means the help page says it does not offer a bulk premium price. For Apartments.com, 6 is the count of network sites named for a basic ad, and "up to 9 times" is the impression claim, not a promise. For Spherexx, 2000 is the year the company says it has been in multifamily. The Marketing Website row on Buildium's comparison has no separate dollar, so it is absent here rather than entered as zero.

The 2 in the Apartments.com basic row is the two-hour edit lag on that listing page. The 48 in the Zillow row is hours of notice. These rows are the raw cutoffs behind the six steps. They are not a score.

An illustrative month, using only published fees

Use this as an illustration for a leasing desk, not as anyone's books. Three vacancies are upgraded as direct listings inside Zillow Rental Manager at $39.99 each, which is 3 × $39.99 = $119.97, and each of those upgrades can run for 90 days, according to Zillow (2026). Eight applicants are then screened at the standard $17 report, which is 8 × $17 = $136, and two leases use an eSign document at $5 on the Essential plan, which is 2 × $5 = $10. The variable pieces add as $119.97 + $136 + $10 = $265.97, before the monthly plan floor. The event a review queue would subscribe to is Applicant.Created. A person still confirms the unit is vacant before that screening charge is placed. Nothing in the arithmetic is a measured customer result, and the $39.99 figure is the direct-post upgrade, not a price for a Buildium feed.

Where each website fits

Zillow Rental Network

Zillow Group's Rental Manager help center is the price record for a listing you post there yourself. A direct listing is free to publish, and the Premium upgrade: $39.99 according to Zillow (2026) buys higher placement for up to 90 days. The page says you get 48 hours' notice before that window ends, premium does not renew by itself, there is no bulk price for several premium listings, and a community of 25 or more units is pointed to a different advertising page. If the listing arrives as a feed, the same article tells you to write to Zillow Group for a price, so the Buildium feed is quote-based. The visit footnote on that article is dated July 2020, so it is not a 2026 traffic rank. Direct posts are described as appearing on Zillow, Trulia, and HotPads.

Best fit: a scattered set of houses, condos, and small buildings where you are willing to upgrade one stuck listing at the published flat fee, and where someone can deactivate a listing the day it is rented. You can turn a listing off, and a repost inside the original paid window is not charged again.

Limitations: do not budget the feed at the self-serve premium fee. Do not expect a volume discount. Do not use the 2020 footnote in an owner report. Large communities are outside the self-serve article.

Implementation: pick direct post or feed before you promise owners a cost. Keep the contact email on the listing, because a feed with no reachable contact fails quietly. Hold screening until the applicant matches a unit that is still open.

Apartments.com

Apartments.com is the right first read for a one-to-four-unit rental because the basic ad has a published free window and a published network count, both cited above. Premium is a 30-day product with unpublished dollars. That split is the whole decision. Use the free window, watch the two-hour update lag, and buy Premium only for a specific listing whose showings are thin. Buildings of 5 or more units start with a phone or email to Apartments.com, so a garden-style property is quote-based even when the fourplex next door is not.

Best fit: houses, townhomes, condos, and small buildings you can describe with a few photos, where 21 days of standard placement is a fair test. Also a fit when you need the ad on the six-site network and you can tolerate paid ads sorting above free ones.

Limitations: the impression and lead multiples are claims on the help page, not a result you can invoice. The premium dollar is hidden until checkout. A five-unit building does not inherit the one-to-four-unit package.

Implementation: publish, wait through the free window, and refresh from the account rather than retyping the rent on a second site. If Buildium is sending the feed, confirm the feed is accepted for that unit count before you tell an owner the ad is included.

Apartment List

Apartment List is named by Buildium as a listing destination, and it is a poor place to assume your fee schedule arrives automatically. The May 19, 2026 fee guide says national fee display was set for April 30, 2026, and it lists fee-file connections for Yardi Voyager, RealPage OneSite, EliseAI, Entrata, Funnel, AppFolio, and Engrain. Buildium is not in that list. The author note on the same page puts Listed units: nearly 6 million according to Apartment List (2026). If your provider is absent, the page says Apartment List has not received an updated fee file from them. A public dollar for the listing itself was not on this page, so the advertising price is quote-based.

Best fit: a manager who already has an Apartment List relationship, who can send a MITS 5 fee file or can accept that fees may not display, and who will confirm the feed with their representative. MITS 5 is the fee format that page names.

Limitations: RealPage OneSite on that list is not the same sentence as Buildium, even though Buildium's footer identifies it as a RealPage company. Do not treat the parent name as proof the fee file flows. Do not invent a per-lease price from memory. This session did not open a page that printed one.

Implementation: organize fee names inside your team, load them in the property system, then ask Apartment List whether the file they receive from you is the listing feed, the fee file, or both. Keep a person on the first applicants until you see the total price a renter would see.

Zumper

Zumper's help article dated September 23, 2026 says an agent, a landlord, or a property manager can post the first few listings for free, and that posting limits vary by region in the United States and Canada. It does not print the regional number. Premium listing plans are offered, and the article does not print their price, so premium is quote-based. The benefits it does name are placement on Zumper, Padmapper, Realtor.com, Microsoft Bing, and Chat GPT, plus a verified badge and richer media such as a 3D tour. Multifamily questions are sent to support. Buildium's syndication page names Zumper as a destination. That names the listing path. It does not publish Zumper's fee.

Best fit: a team that can live with a free starting allotment of unknown size, and that will ask Zumper what the cap is in its cities before promising owners a $0 channel. Also a fit when Padmapper and Realtor.com matter and you are ready to hear a premium quote.

Limitations: "first few" is not a number you can put in a budget. A second portfolio in another metro may hit a different cap. There is no published bulk table in the article.

Implementation: open the regional question with Zumper before the feed is on. Track which vacancies consumed the free allotment. When the allotment is exhausted, pause and get the premium quote in writing. Do not assume the Buildium click includes promoted placement.

Rental Beast

Rental Beast's page for management companies tells property managers to add listings through their property system, and it names Buildium in that list along with AppFolio, Entrata, MRI, RealPage, Rentec Direct, and Yardi. It says listing is free and that owners and managers never pay to list. It also says you only pay on signed leases, and it does not print that lease fee, so any success charge is quote-based while the list fee on the page is $0. The same page states Listing inventory: 9,000,000+ according to Rental Beast (2026), with 50,000+ agents and 150,000+ landlords. Other Rental Beast pages show different counts. This guide uses only this page, so those other counts are not repeated here.

Best fit: a manager who wants agent-distributed rentals, who is willing to be on an MLS-linked network, and who can accept a possible pay-on-lease conversation that has no public dollar. Also a fit when you want Buildium named by the receiving site, not only by Buildium.

Limitations: "free to list" and "only pay on signed leases" sit on the same page. Read both before you tell an owner the channel is free. No unit cap is stated, which is not the same thing as a promise that every building is accepted. This guide does not import testimonials from that page.

Implementation: connect the property system using Rental Beast's own setup notes for your software, then claim or correct the listing so the contact is yours. Decide in advance what referral or lease fee you will accept if a signed lease is the billed event. Keep your application path, because the page says you do not have to change it.

Spherexx I Love Leasing

Spherexx is the company-site and leasing-desk option in this set, not another public listing portal. Its marketplace listing says the Buildium connection is one-direction: Spherexx can pull data out and cannot push data into Buildium. It says available units, timing, and price sync, that the resident list comes across, and that application results in Buildium update the leasing record. Spherexx has been in multifamily since a Company start: 2000 according to Spherexx (2026). No monthly price appears on that listing, so I Love Leasing is quote-based. On Spherexx's own Buildium page, touchscreen kiosks and commission management are labeled as products that do not integrate with Buildium. Do not buy those add-ons on the assumption that they share the leasing connection. The leasing page is here: Spherexx on Buildium.

Best fit: a multifamily desk that wants availability and price on a leasing workspace, that can live with a one-way data pull, and that will get a written quote. Also a fit when application status should show up for the leasing team without a second typing pass.

Limitations: this is not a substitute for Zillow or Apartments.com. It does not, on the pages read here, publish a setup fee or a monthly fee for the Buildium connection. Bi-directional communication with residents is described separately from the one-way data pull. Those are different pipes. Website theme prices that are not tied to Buildium on the page you are buying should not be used as the integration price.

Implementation: review the permission list in the marketplace flow, confirm which fields are read, and test one community before you turn on the rest. Keep a person on application-status changes for the first weeks so a pulled record is not treated as a decision.

Buildium Marketing Website

The plan comparison on Buildium's pricing page includes a Marketing Website line beside syndication, prospects, and applicants. This guide did not find a separate dollar for that line, so it is not entered as $0 and not entered as a third-party invoice. The cost you can read is the plan floor itself. The syndication page says you can post to your website and also send the vacancy outward. That is the included site: one place on the same login, with the same unit record.

Best fit: a manager who needs a basic public page for the company and the vacancies, who does not need a custom design engagement, and who will still use one or two of the named listing sites for reach. It is the default, not the whole market.

Limitations: a line on a plan grid is not a design shop, a local search program, or proof of a two-way guest-card product. If you need a designed property site with a quoted build, you are in the Spherexx conversation or with another firm, and you should make them name Buildium in the quote. Do not assume photos, floor plans, or fee calculators beyond what your plan page shows you in the account.

Implementation: fill the unit the way the syndication steps describe, choose the destinations, and check the company site after the two-hour class of delay you already accept on other sites. When the company site and a portal disagree, the person who releases Rental.Updated holds the company site until the rent and the contact email match.

Stitching this in Zapier, Make, or n8n

The practical alternative is to catch the lead in Zapier, Make, or n8n, or to have a staff developer post the vacancy by hand. Those tools can keep run histories, retries, error branches, and an audit trail when someone configures them. The buyer then owns observability, meaning you can see each run, idempotency, meaning a repeated webhook does not open a second applicant, plus escalation, access controls, and maintenance when the field names change. That is a fair choice for a single site and a leasing manager who will read the error log. It is a weaker choice when five sites can create the same person and nobody has written the rule for a duplicate.

A proposed US Tech Automations design could subscribe to Applicant.Created, fetch the applicant only after the signature on the webhook checks out, and park screening until a named person approves the unit. The prerequisite is still the Premium plan's Open API and a callback your company hosts. The difference you would be buying is a shared release rule and a held state, not a promise that the ad fills faster. You would still review the first weeks of output yourself. If the Zapier path already does that, and the volume is a handful of vacancies, keep the tool you have.

When NOT to use US Tech Automations

Stay with the listing site's own inbox when you have few live vacancies and one person already reads every lead the same day. Stay with Zapier, Make, or n8n when that flow already retries, already blocks a duplicate, and a person already approves screening. Stay inside Buildium's applicant checklist when the only message you need is the stage email the product already sends, and you are not merging several websites into one queue. In those three cases a simpler tool is the better buy, and adding a second system would only give you another place to check.

Mistakes that keep a vacancy dark

• Copying the direct-post premium fee onto a Buildium feed. The help article sends feed pricing to a separate conversation.

• Reading Apartment List's fee-file list as if Buildium were on it. The listing name and the fee file are different rows.

• Buying a premium upgrade on the first morning for a small building that still has a published free window.

• Describing Spherexx as a two-way write into Buildium. The marketplace listing says the data pull does not push back.

• Putting an old visit footnote into a 2026 owner packet. The date on that footnote is not this year.

• Ordering a screening report from a website lead before a person matches the person to a unit that is still vacant.

Any one of these can be fixed without a new vendor. Most of them are a reading error, not a software gap.

Terms on the listing page

• Syndication: Buildium sends a vacancy to a rental website, or you turn that send on for a chosen site.

• Feed: the connection that carries the unit, the rent, and the contact. It is not the same file as a fee schedule.

• Internet listing service: a rental website shoppers search. Apartment List uses the phrase when it talks about fee delivery.

• MITS 5: the fee format Apartment List names for moving required and optional fees onto a listing.

• Premium listing: a paid upgrade with a published duration. On Zillow the direct fee is published. On Apartments.com the dollar is not.

• Open API: the connection the Premium plan card adds, which is what a webhook such as Applicant.Created requires.

• Total price: rent plus the fees a manager sends, which Apartment List set as the display standard for April 30, 2026. It is not base rent alone.

Questions managers ask before connecting a site

Which websites does Buildium name for syndication?

Buildium's syndication page names Zillow, Apartments.com, Apartment List, Dwellsy, RentPath, Zumper, and Rental Beast, and the page body also names Craigslist and your own website. Use that page as the roster, then confirm the one site you intend to pay.

Is a basic listing on Zillow or Apartments.com free?

A listing posted directly in Zillow Rental Manager is free to publish, and a basic Apartments.com listing is free, with a 21-day window for a 1-to-4-unit property. A feed that Buildium sends can still be a separate, quote-based contract.

Do I need the Premium plan to connect a custom review queue?

Yes, if the queue depends on Open API. The Premium plan card is the summary that adds Open API. The Essential and Growth summaries do not.

Should I buy a premium upgrade on day one?

No. Run the published free window on a small-building ad first, then upgrade the specific listing that is not getting showings. Buy a quote-based product only after the price is in writing.

Can Zapier, Make, or n8n cover the path from website to applicant?

Yes. They can move the lead and store a run history when you configure retries and error branches. You then own duplicates, access, and upkeep, which is a good trade when one person watches the log.

What has to happen before anyone pays for a screening report?

A person on your team has to confirm the unit is still vacant and that the applicant is for that unit. The website event is only the notice. The $17 standard report, the $20 enhanced report, and the $35 applicant-paid report are all real charges on the pricing page, so the match should happen first.

Where this leaves the short list

For a house or a small building, start with the free direct paths you can read: a basic Apartments.com window, a free direct Zillow post, and a Rental Beast listing if an agent network fits and you have asked what a signed lease would cost. Add Zumper only after you know the regional cap. Treat Apartment List as a listing destination that still needs a fee-file check. Use Spherexx when the gap is the leasing desk, not another portal, and only on a written quote. Use the Marketing Website line as the company page you already have inside the plan, not as a custom build. Leave Dwellsy, RentPath, and Craigslist unnamed in the budget until you open a current price.

The bills that repeat are still inside Buildium: the plan floor, the screening report, the signature, and the bank transfer. The websites change who sees the door. They do not replace the person who decides the application is real. Managers who want that release rule held in one queue can see how US Tech Automations configures this.
