If you manage rental units or community associations in the U.S. or Canada, you will run into Buildium and AppFolio within about ten minutes of looking for software. Both are mature, cloud-based platforms that handle accounting, maintenance, owner and resident portals and online payments. Both now sell AI assistants. Both have loyal users and frustrated ex-users.
They are not interchangeable, though, and the difference starts with a simple question: how many doors do you manage?
The short version
Buildium is easier to start with. It doesn’t list a unit minimum, publishes “starting at” prices, and its entry plan is explicitly aimed at small management companies and self-managed associations of 40 units or fewer (one version of the same page says 150, so ask) (Buildium).
AppFolio is built for portfolios. It charges per unit, per month, and its Core plan carries a 50-unit minimum plus a minimum spend that it doesn’t publish (AppFolio). If you manage 30 units, that settles the question. If you manage 3,000, the conversation is about features, support and integrations, and you’ll be negotiating either way.
Between those extremes, it comes down to how you work. I’ll go through the parts that actually decide it.
Pricing, as published
Here is what each company showed on its own pricing pages in October 2026.
| Plan | Buildium | AppFolio (residential) |
|---|---|---|
| Entry | Essential, from $65/month | Core, $1.49 per unit/month (50-unit minimum, minimum spend applies) |
| Mid | Growth, from $202/month | Plus, $3.20 per unit/month (minimum spend and unit minimums apply) |
| Top | Premium, from $420/month | Max, $5.00 per unit/month (minimum spend and unit minimums apply) |

Two caveats matter more than the headline numbers. First, Buildium’s prices are floors that rise with unit count, and Buildium tells portfolios of more than 5,000 units, and community association managers, to call for pricing. Second, AppFolio’s per-unit figures are for its residential product. Community associations are priced separately. AppFolio’s pricing page lists its community association platform at $0.85 per unit per month in its product data, but the visible page asks you to contact sales, and the minimum spend isn’t published (AppFolio). Treat that as a starting point, not a quote.
Neither price includes everything. Payment processing, tenant screening, eSignatures and onboarding can all be extra, and these fees add up. Ask both vendors for a first-year total for your actual portfolio, in writing, including implementation.
Who each one fits best
Small and growing rental managers, roughly up to a few hundred doors, tend to find Buildium more approachable. You can sign up, set up a few properties and see whether it works before talking to anyone. The Essential plan covers basic accounting, maintenance and leasing, and every plan includes violations tracking, online portals and board communications.
Larger, multi-market operators often lean toward AppFolio. Its pitch is one platform for everything, with heavier automation and specialist add-ons. The Plus tier adds affordable and student housing capabilities, advanced budgeting, custom fields and a read-only API, and Max adds a leasing CRM, read/write API access and a dedicated customer success manager (AppFolio).
Community association managers can make either work. Buildium lists association accounting, payables with approvals, violations management, architectural requests with committee voting and board management on its association page (Buildium). AppFolio’s HOA product covers mobile violations, online architectural reviews routed to the review committee, homeowner and board portals and common-area maintenance requests (AppFolio). The feature lists look similar on paper. The real difference is the minimum: a manager with a handful of small associations may struggle to reach AppFolio’s floor.
Self-managed boards are a special case. A volunteer board running one 25-home association doesn’t need a property management platform built for leasing. Buildium’s Essential plan is designed with that user in mind, but simpler HOA-specific tools may be a better fit. We’ll cover those in a separate comparison.
Accounting and banking
For most managers, accounting is the reason to switch, and the reason to stay.
Buildium includes property, association and unit-level accounting, bank reconciliation with transaction sync and matching, accounts payable with approvals and 1099-NEC e-filing in the U.S. Association bank syncing sits on Premium. AppFolio’s Core includes property accounting and reports, purchase orders and inventory tracking, with advanced budgeting and its “Accounting Performer” bill entry and close tools on the higher tiers.
If you are moving from spreadsheets or QuickBooks, either will feel like a big step up. If you are moving between the two, plan on a proper data migration, a parallel month, and an accountant who checks the opening balances. Every manager I know who skipped that last step regretted it.
AI features: useful, but don’t buy on them
Both vendors lead with AI right now. Buildium bundles an AI assistant at the entry level, with AI-enhanced communications on Growth and its full AI and automations suite on Premium. AppFolio includes its Realm-X assistant and messaging on Core, with Realm-X “Flows” automation on Plus.
These tools can save real time on drafting replies, summarising maintenance requests and building reports. But they change quickly, and demos are always smoother than Monday morning. Judge them on a trial with your own data, and make sure the core accounting and maintenance workflows suit you even if you never touch the AI.
Support, contracts and switching
Support levels are tied to plan on both platforms. AppFolio’s Core gets standard support, Plus gets enhanced support, and Max gets a dedicated success manager. Buildium’s Essential plan gets ticket support, Growth and Premium add live phone support, and guided onboarding is mandatory on Growth and Premium (Buildium). Before you sign, ask how support is delivered (phone, chat, ticket), what the response times are, and whether onboarding help is included or billed separately.
Read the contract term and the exit terms. How do you get your data out, in what format, and what does it cost? You may never need it, but a vendor that is vague about exports is telling you something.
Questions to ask in the demo
Sales demos are built around the vendor’s best workflow, so bring your own. Pick one awkward property, the one with a commercial unit on the ground floor or the association with two classes of assessment, and ask the rep to set it up live. Ask how late fees are calculated and whether you can change the rules per property. Ask what happens when an owner pays part of a bill online and the rest by cheque. Ask to see an owner statement and a board financial package exactly as your clients would receive them, not a sample PDF.
Then ask the money questions. What are the card and ACH fees, and who pays them, you or the resident? Is onboarding mandatory, and what does it cost? Is there a price increase cap at renewal? A rep who answers those questions clearly is a good sign. If the answers keep coming back as “we’ll follow up,” treat that as part of the evaluation too.
Outside the U.S. and Canada
Both products are built around North American accounting, payments and tax workflows, including features like U.S. 1099 filing. Strata managers in Australia, block managers in the UK and housing company managers in Europe generally use local platforms built around their own rules, such as levy notices tied to unit entitlement in NSW, Section 20 consultation workflows in England, or the separate operating and financing charges common in Finland. If you are outside North America, check local requirements before shortlisting either.
How I would choose
Count your doors honestly, including what you realistically expect to add in the next two years. If you’re under 50, start with Buildium’s trial and see if it fits; AppFolio isn’t an option yet. If you’re between 50 and a few hundred, shortlist both, get first-year totals in writing, and run each with a real property for a couple of weeks. If you’re well into the hundreds or thousands, you’ll be negotiating, so make the vendors compete on implementation help and support as well as price.
Then pick the one your accountant and your maintenance coordinator prefer. They’re the people who will live in it every day.
Frequently asked questions
Is Buildium cheaper than AppFolio?
For small portfolios, usually yes, because AppFolio’s Core plan has a 50-unit minimum and a minimum spend. At larger sizes the comparison depends on unit count, tier, fees and what you negotiate. Get written first-year quotes from both.
Does AppFolio work for HOAs?
Yes. AppFolio sells a community association product with violations tracking, architectural reviews, portals and maintenance requests. It is aimed at management companies, and it carries a 50-unit minimum and minimum spend.
Can a self-managed HOA use Buildium?
Yes. Buildium describes its Essential plan as suited to self-managed associations of 40 units and under. Smaller boards should also compare HOA-specific tools that may be simpler and cheaper.
Do Buildium and AppFolio offer free trials?
Buildium offers a 14-day free trial with no credit card required (Buildium). AppFolio routes buyers through a demo with sales.
Can I use either outside the U.S.?
Both are designed mainly for the U.S. and Canada. Managers elsewhere should check local accounting, tax and legal requirements before choosing.
