Buildium vs AppFolio

The two platforms running most of the rental industry

I spent a month talking to property managers about their software. Nearly every conversation came back to two names. Buildium and AppFolio together manage tens of millions of rental units in the US. They have been competing for over 15 years, and that competition has made both products sharper. But they have pulled in different directions over time. Which one fits you depends on your portfolio size, your property types, and how fast you plan to grow.

Pricing: the small-portfolio math

Buildium publishes their prices. Essential starts at $55 a month for up to 20 units. Growth is $174 a month for up to 200 units and adds tenant screening and online rent payments. Premium is $374 a month for up to 5,000 units and adds open API access and priority support. At 200 units on Growth, you are paying under a dollar per unit per month. The more you scale, the better the unit economics get.

AppFolio has a minimum monthly spend that essentially rules out portfolios under about 50 units. It starts around $280 a month for up to 50 units and scales to roughly $1.40 per unit for residential above that. There is an onboarding fee that scales with portfolio size. Commercial and mixed-use have a separate pricing tier.

For a landlord with 30 single-family rentals, the math is not close. Buildium costs a fraction. For portfolios between 200 and 500 units, the pricing converges to roughly even. Above 1,000 units, both go to custom enterprise pricing, and cost becomes secondary to feature fit.

Accounting: why property managers switch to Buildium

Buildium was built by property managers who were done with QuickBooks. The accounting module reflects that origin. It handles 1099 e-filing, CAM reconciliation, and owner contribution tracking natively. The chart of accounts is property-management-specific out of the box. Bank reconciliation follows the logic a property manager expects. If you do not have a dedicated real estate accountant, Buildium's books are easier to set up and harder to mess up.

AppFolio's accounting is stronger on the institutional side. It handles inter-entity transactions, consolidated reporting across portfolios, and cost allocation at a level that matters for owners with complex structures. The trade is that AppFolio's accounting has a real learning curve.

If you are coming from QuickBooks or Excel, Buildium will feel more familiar. If you are coming from an enterprise ERP, AppFolio will feel more capable. Different starting points, different right answers.

Tenant experience: where AppFolio pulled ahead

AppFolio put real money into the tenant-facing side. Its AI assistant Lisa handles common tenant questions through a chat interface. Rent balance. Maintenance status. Lease renewal dates. Available 24/7. The AI tenant screening goes beyond credit scores, analyzing rental history patterns for red flags that standard screening misses. Whether that is worth the price difference depends on your vacancy rate and how much time your staff spends answering the same five questions.

Buildium's tenant portal covers the essentials well. Online rent payment, maintenance requests, lease documents, communication with the property manager. It works. No AI chatbot. No advanced screening algorithms. For most tenants, Buildium's portal does what they need. The real question is whether an AI chatbot meaningfully reduces your staff workload or just looks good in a demo.

Maintenance: automation vs simplicity

Both platforms handle work orders, vendor assignment, and status tracking. AppFolio adds automated vendor matching that suggests qualified vendors by work type and location. Tenants can upload photos and video of issues, which sometimes saves a trip. Buildium's maintenance module is simpler. Create work order, assign vendor, track completion, bill the owner.

For a portfolio where the property manager knows their vendors personally and maintenance volume is manageable, Buildium is plenty. For larger portfolios where maintenance volume is a real operational challenge, AppFolio's automation saves payroll hours.

The growth question nobody asks early enough

I have watched this pattern play out more than once. A property manager starts on Buildium at 100 units. Loves the accounting. Grows to 800 units over five years. At that scale, the things that made Buildium great at 100 units start feeling like constraints. They need batch operations, deeper automation, enterprise reporting. So they migrate to AppFolio.

The migration is expensive and messy. Tenant ledgers, owner histories, maintenance records. Data migration between property management platforms is never clean. Manual reconciliation happens. If you are at 200 units and growing 30 percent a year, the question is not which platform fits today. It is which platform fits three years from now. If your trajectory takes you past 500 units, starting on AppFolio saves a painful migration. If you expect to stay under 500, Buildium costs less and works well.

How I would choose

Under 200 units: Buildium. The accounting and pricing win. Between 200 and 500: depends on your growth rate. Growing fast means lean toward AppFolio and skip the migration headache. Stable means Buildium handles the portfolio fine. Over 500: AppFolio. The automation and enterprise features stop being nice-to-have.

The real mistake is picking based on a demo. Demos show you the features the vendor is proud of. They do not show you what breaks at scale or what your staff will hate in six months. Talk to someone who manages a portfolio similar to yours. Buy them coffee. Ask what they wish they had known.
