Buildium vs Avail 2026: PM Suite vs DIY Landlord Stack

Buildium is built for someone who manages property as a business — third-party PMs, multi-owner accounting, real owner statements. Avail (Realtor.com) is built for a landlord with 1–10 units who wants leasing tools without paying a subscription. Past 10 doors managed for other people, Avail runs out. Below 25 doors managing your own units, Buildium is heavier than you need.

This is a comparison between two different products that get lumped together because both touch leasing and rent collection. The picks below assume you've actually identified which side of the line you're on.

TL;DR verdict

• Choose Buildium if: you manage property for other owners, you need a trust account that survives an audit, you produce owner statements monthly, or your portfolio is past 25 doors with mixed owner entities.
• Choose Avail if: you own and self-manage 1–10 units, you want professional listings, screening, and lease docs without a monthly subscription, and your "accounting" is a spreadsheet plus a bookkeeper at tax time.
• Choose neither if: you're 15–50 doors self-managing your own units — Buildium's accounting tax is heavy for one beneficial owner, and Avail's per-feature paid add-ons start to outweigh a real subscription tool.

Pricing structure

Buildium is a per-unit subscription with a starter base; Avail is freemium with paid features priced per unit per month or per feature.

What it costs in practice:

• Buildium at 25 doors: $400–$600/mo all-in. At 100 doors: $1,200–$1,700/mo. Get any quote in writing.
• Avail with 5 doors on the free tier: $0/mo for the landlord (tenant pays card fees, possibly the screening fee). Same five doors on Unlimited Plus is a small per-unit monthly add-on, often a few dollars per unit.

The shape of the spend matters more than the headline. Buildium is a real operational cost. Avail is functionally free if you can live without owner accounting.

Features that actually matter

Trust accounting

• Buildium: Three-way reconciliation, owner draws, holdbacks, audit-ready. The reason third-party PMs pay for it.
• Avail: Not a trust-accounting product. Rent flows to your bank account; bookkeeping happens elsewhere.

Edge: Buildium, decisively, the moment you manage someone else's money.

Tenant experience

• Buildium: Tenant portal, AutoPay, mobile app. Functional, dated UI relative to newer entrants.
• Avail: Modern tenant experience, CreditBoost (reporting rent to credit bureaus), clean mobile flow. Tenants who use Avail tend to like Avail.

Edge: Avail.

Leasing and screening

• Buildium: Listing syndication included, applicant pipeline, screening (TransUnion), state-aware leases, eSign credits.
• Avail: Listing syndication to Realtor.com and others (it's owned by Realtor.com), screening, state-specific lease templates, eSign.

Edge: Tie for outcomes. Avail's listings get distribution advantages through the Realtor.com network; Buildium's leasing workflow is more PM-shaped.

Maintenance

• Buildium: Work-order workflow, vendor portal, W-9 and insurance tracking.
• Avail: Tenant submits a request; you coordinate the vendor manually. There is no vendor portal.

Edge: Buildium the moment vendors are in the loop.

Owner-facing reporting

• Buildium: Owner portal, custom statements, distribution workflow. Built for this.
• Avail: Not a feature; there is no separate concept of "owner" from "landlord."

Edge: Buildium.

Mobile experience

• Buildium: Tenant app is fine, staff mobile is thin.
• Avail: Mobile-first across the board. Strong tenant app.

Edge: Avail.

What both don't tell you

• Avail's "free" is real but narrows fast. Want faster ACH, state-specific lease packages, or premium support? Those move to the paid tier per unit. Five doors free is real; fifteen doors with all the extras starts to feel like a subscription anyway.
• Buildium per-door fees creep at 100+ doors. Renewal negotiations are the lever. Most operators do not realize the discount is on the table until year three.
• Avail's screening is tenant-paid by default. If you have a competitive market and don't want applicants to fund their own screening, switch the setting — but understand the line item moves to you.
• Buildium's UI shows its age. Operators onboarding in 2026 frequently describe it as "1.0 inside a 2026 skin." It works; it doesn't delight.
• Neither is set up for commercial. Avail is residential-only. Buildium can hold a commercial lease but lacks CAM reconciliation, percentage rent, and escalation logic.

Decision matrix

If you're a self-managing landlord crossing 15–25 doors and the Buildium quote feels like a tax for capabilities you don't need, the flat-priced PM category exists for exactly that gap. Proprietio is one option there — flat monthly, no per-door fees, built for mixed portfolios.

FAQ

Can Avail handle owner accounting? No. It's a landlord product. The moment you have a second beneficial owner you need real owner statements for, you've outgrown it.

Is Buildium worth it under 25 doors? Usually no, if you're self-managing your own units. Buildium's value is in the accounting depth, which is overkill for a single owner.

Does Avail charge me or my tenants for ACH? On the free Unlimited tier, ACH is free for the tenant. On Plus, ACH is faster and free. Card payments charge the tenant a percentage on both tiers.

Can I migrate from Avail to Buildium? Yes. Export tenants, leases, payment history, documents. Plan 2–4 weeks at 10 doors. The bigger lift is reconstructing any historical accounting that lived in QuickBooks.
