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.

PRICING

Buildium: Essential $62/month, Growth $192/month, Premium $400/month — flat tiers, no per-unit fee, no minimum unit count.

AppFolio: Core $1.49/unit ($298/month minimum, 50-unit floor), Plus $3.20/unit ($960/month minimum), Max $5/unit ($7,500/month minimum) — all quote-confirmed.

WHO EACH ONE IS BUILT FOR

Buildium fits portfolios from small up to roughly 5,000 units without a strict entry floor.

AppFolio realistically fits 200+ units, where its minimums stop dominating the cost. Below 50 units, it isn’t available to you at all — not a pricing question, a signup requirement.

FEATURE DIFFERENCES WORTH KNOWING

Both offer AI/automation layers — Buildium’s Premium-tier suite versus AppFolio’s Realm-X, which also connects to outside AI systems and reportedly saves some larger operators 10+ hours a week on reporting and leasing. Buildium’s report customization is more limited, and phone support is gated behind its $192/month Growth tier; AppFolio’s support response times run slower than advertised according to several reviewers.

THE ACTUAL DECISION

If you’re under 50 units, this isn’t really a comparison — Buildium is the only one of the two you can sign up for. Above roughly 200 units, AppFolio’s per-unit economics and deeper automation start to justify the cost Buildium’s flat tiers don’t scale into as cleanly.
