Can I use AppFolio if I have fewer than 50 units?

No. AppFolio has a hard 50-unit minimum just to sign up. Buildium has no unit-count floor, so it is the only one of the two available to smaller portfolios.

Which has better automation, Buildium or AppFolio?

AppFolio's Realm-X automation layer is deeper and connects to outside AI systems, with some larger operators reporting it saves 10+ hours a week on reporting and leasing. Buildium's automation suite is limited to its Premium tier.

WHAT TO ASK EACH

Buildium: how the monthly price changes at your unit count, and what is gated at each tier. AppFolio: the dollar minimum per tier in writing, and whether Realm-X Performers are billed as add-ons. AppFolio’s support response times run slower than advertised according to several reviewers, so ask about onboarding support too.
