Buildium vs Avail 2027: Which Fits Your Rental Business

The short answer for most readers

Pick Buildium if you manage rentals for other owners, hold their money, or owe them statements. Pick Avail if you self-manage a small portfolio and mainly need listings, leases, screening and rent collection without a monthly base fee. Accounting obligations decide this more than feature count does.

A property management platform is software that runs leasing, rent collection, maintenance requests and bookkeeping for rental units in one system. Buildium and Avail both cover the leasing and rent-collection core. They diverge on accounting, owner reporting and integrations, and the price gap depends on how many units you run.

Ownership matters before you commit. Move Inc., the parent company of realtor.com, acquired Avail in December 2020, according to Inman (2020), and Avail's pricing page now shows Realtor.com branding in its header and footer. Buildium has been owned by a larger company since 2019: RealPage agreed to pay $580 million for Buildium according to HousingWire (2019).

TL;DR: Avail is the cheaper start for self-managed landlords with a few units. Buildium is the stronger choice once you need owner statements, double-entry accounting or an API.

Key Takeaways

• Buildium is the stronger choice for management firms that need double-entry accounting, owner statements and an Open API. The API is only in its Premium tier.

• Avail's Unlimited plan costs $0 per unit and its Unlimited Plus plan costs $9 per unit a month, while Buildium's Essential plan costs $65 a month, so Avail's base price is lower up to seven units, before Buildium's per-transfer fees.

• At eight units, Avail's Unlimited Plus costs $72 a month, against $83.80 for Buildium's Essential plan once eight $2.35 incoming transfers are counted, so Avail is $11.80 a month cheaper.

• Avail's pricing page does not describe owner statements, trust accounting or a public API, and we found no public Avail API documentation.

• Both products sit inside larger parent companies, so get pricing and roadmap commitments in writing before you sign.

How we evaluated these tools

These weights are our judgment about what an owner or operations lead at a small management business decides on. Every figure below comes from a page we opened in November 2026. We ran no trial of either product for this guide, so the weights are a starting point. If one criterion decides your choice, raise its weight and recheck the table.

Our analysis: cost gets the most weight because it is the one number both vendors publish plainly. Accounting depth comes next because it decides whether someone has to rebuild records outside the platform at tax time.

Feature-by-feature comparison

The matrix below uses only what the vendor pages or independent reviews state. Where a page is silent, we write "not described" rather than assume a feature is missing.

Our analysis: the split is structural, not cosmetic. Buildium's own comparison article argues the gap widens as operations grow in accounting depth, owner reporting and integrations. Buildium wrote that article, so weigh it as a vendor view: Buildium's comparison article.

Pricing and total cost at your unit count

Buildium publishes a monthly price for each plan, while Avail publishes a price per unit. Pricing checked November 10, 2026.

Buildium's Essential plan costs $65 a month according to Buildium (2026), and the same page lists Growth at $202 a month and Premium at $420 a month. Avail's Unlimited Plus plan costs $9 per unit according to Avail (2026), and the Unlimited plan costs $0 per unit.

The fee schedule below shows the per-transaction charges behind those totals.

Our analysis: these are base prices only. At seven units, Avail's Unlimited Plus costs $63, below Buildium's $65 Essential base, and at eight units it costs $72. Against Growth at $202, Avail's Unlimited Plus passes the price at 23 units ($207 against $202). Against Premium at $420, it passes at 47 units ($423 against $420). Buildium's per-transfer and screening fees come on top of its base price, so the Buildium side of each comparison is understated.

Running the numbers for an eight-unit portfolio

Take an owner with eight units whose tenants all pay rent by bank transfer each month. On Buildium's Essential plan the base is $65, and eight incoming transfers at $2.35 add $18.80, so the monthly total is $83.80 before screening and eSignature charges. On Avail's Unlimited Plus plan the subscription is 8 × $9 = $72 with ACH charges waived, so Avail comes out $11.80 a month cheaper, or $141.60 a year. The math changes once the owner wants automation that reads Buildium data: the Open API sits in the $420 Premium tier, which works out to $420 ÷ 8 = $52.50 per unit before transfer fees, a cost that only makes sense if the owner needs that API. If the owner builds that sync in n8n, a failed run can surface through a field such as execution.error.message in n8n's error workflow, and someone still has to watch the alert and fix the cause.

Who this is for

Buildium is for operations leads at firms that manage other owners' properties, handle client funds, need owner statements or expect to add staff. Red flags: you only manage your own doors and will never need owner reporting; a $65 monthly base price is more than your budget can carry; you need a documented API but will not pay for the Premium tier.

Avail is for owners who self-manage a small portfolio and want listings, lawyer-reviewed leases and rent collection without a base fee. Red flags: you need owner statements or double-entry books; you manage properties for other owners; you need an integration, and we found no public Avail API documentation.

Vendor profiles: where each product fits and falls short

Buildium

Best fit is a firm that needs accounting depth. Buildium's comparison article lists double-entry bookkeeping, owner statements, 1099 e-filing and trust accounting, and it puts those features at the center of its pitch: Buildium's comparison article. The independent picture is more mixed. The Close's 2025 review says portfolio analytics are limited to Growth and Premium and that onboarding costs extra, and it reports Essential charging $5 per e-signature according to The Close (2025). That e-signature figure matches the current pricing page.

Limitations: The Close also lists limited listing marketing tools and no dedicated CRM for lead management. Live phone support is not on Essential, so a team that needs phone help should budget for Growth at $202 a month or more.

Implementation: start with the 14-day trial, which needs no credit card and runs on sample data. Buildium's pricing page says onboarding is required for new Growth and Premium customers, and its comparison article says that onboarding includes data migration. Budget a migration step before go-live, and confirm which tier includes the owner portal, because the plan-by-plan grid did not render in our research. Plans can be changed on the Account and Billing page, and the pricing page lists no contract length.

Avail

Best fit is an independent landlord or investor with a small or moderate portfolio. The Close's September 2026 review says Avail "is best for independent landlords and investors" and reports a $2.50 tenant ACH fee under the Unlimited plan according to The Close (2026). More than 90 percent of Avail's customers use the free tier according to Inman (2020), which shows the company's business was built on that tier.

Limitations: The Close calls Avail's accounting "not full accounting software" and says it lacks a general ledger, bank reconciliation, trust accounting and owner distributions. Team, owner and vendor management are limited. FastPay and application customization require the paid tier. The Close also notes that Zillow, Trulia, HotPads and Apartments.com appeared as partners in older Avail reviews but are not in the current network.

Implementation: sign up free, add properties, and choose state-specific leases. The Unlimited plan lists your property on 19 sites, and the paid Unlimited Plus plan adds FastPay, custom application questions and a branded website. The pricing page states no contract terms.

Where a DIY stack or a managed build fits

The real alternative for many buyers is a stitched stack: a spreadsheet plus Zapier, Make or n8n, or an in-house build. These tools can keep run histories, retries, error branches and audit evidence once they are configured. n8n, for example, sends failed executions to a separate error workflow through an Error Trigger, and its Executions view keeps failed and past runs according to n8n.

Make and Zapier also document error handling and retry behavior, but we did not open those pages for this guide, so check their current docs before relying on any specific retry setting. Whichever tool you use, the buyer owns idempotency (a retry must never post the same rent payment twice), escalation paths, access controls for API keys and maintenance when Buildium or Avail changes a field. US Tech Automations builds, runs and supports custom automation workflows as a managed service, so the choice is between owning that work and paying someone to own it.

A proposed design for a Buildium office would start with a trigger: an overdue rent line appears in the ledger, detected through the Open API. The action would pull the lease and tenant record, match the unit, and stage a reminder with the balance due. The output would be a draft in an approval queue, where a staff member approves, edits or rejects each message before it sends, and any escalation waits for that approval. Prerequisites are the Premium tier, API keys created by an authorized Buildium user, a mapping of charge types to reminder templates, and a named owner for the queue. This is a configurable design, not a live deployment, and we have not confirmed a prebuilt Buildium connector, so the build would start from the API.

For Avail, the same design would depend on whatever export Avail provides. We found no public Avail API documentation and did not verify its export options, so a manual export step becomes a review point of its own.

When NOT to use US Tech Automations: skip a managed build if Avail's free tier covers your needs, because a few self-managed units need listings and rent collection rather than a workflow. Skip it if you already run Buildium's standard reporting and can handle reminders by hand. Skip it if no one on your team can own an approval queue or API keys, because the workflow will stall without an owner.

Common mistakes buyers make

• Comparing base prices only and forgetting per-transfer and screening charges, which sit on top of Buildium's plan price.

• Assuming Avail's free tier includes owner statements or double-entry books. The Close says it does not.

• Buying Buildium's Premium tier for the Open API before anyone has a concrete use for it.

• Treating Buildium's trial as a test with your data. The trial runs on sample data.

• Relying on older review prices. The Close's March 2025 Buildium review predates current pricing, so check the live page.

• Missing the crossover point where Avail's per-unit price passes Buildium's Growth plan as your portfolio grows.

• Ignoring ownership. Both products sit inside larger companies, so get pricing commitments in writing.

Frequently asked questions

Is Avail still a standalone product?

No. Move Inc., the parent company of realtor.com, acquired Avail in December 2020, and its pricing page now shows Realtor.com branding in its header and footer.

Does Buildium have a free plan?

No. Buildium lists three paid plans and a 14-day free trial that requires no credit card and uses sample data.

Which is cheaper, Buildium or Avail?

With Buildium's $2.35 incoming transfer fees counted, Avail's Unlimited Plus is cheaper at eight units: $72 a month against $83.80 for Buildium's Essential plan. On base price alone, Avail is cheaper up to seven units and Buildium's $65 Essential plan is cheaper from eight units, but that base-price figure leaves out Buildium's transfer fees. Buildium also lists features Avail does not describe, such as owner statements.

Does Avail offer an API?

We found no public Avail API documentation, and its pricing page lists no API tier. Plan for exports or a manual process if you need data outside the platform.

Does either product require a long contract?

Neither pricing page states a contract length. Buildium says plans can be changed on its Account and Billing page, and Avail's page lists no contract terms.

Choosing before your next renewal

If your operation is a self-managed portfolio that needs listings and rent collection, Avail's free tier is a rational first step, and you should revisit the choice when you need owner statements. If you manage for other owners, the question is whether your accounting and API needs justify Buildium's top tier, and that tier's price is on the pricing page.
