What the pricing really means
At first glance, RentPost looks cheaper at $30/month vs $62/month. But sticker price is only part of the story. Look at what is included on the base plan, how many users you get, and whether you need add-ons to get the features you actually need. The $99/month plan that requires $200 in add-ons is actually more expensive than the $250/month plan that includes everything.
Where Buildium wins
- Full general ledger accounting with 1099 e-filing built in. Your bookkeeper or CPA will appreciate not having to reconcile a separate system
- Tenant and owner portals actually work well. Tenants submit maintenance requests and pay rent online. Owners see statements without emailing you
- Scales from 20 units to thousands without forcing a platform switch. You just move up a plan
- 14-day free trial comes preloaded with sample data so you can test workflows without entering fake tenants
Where RentPost wins
- Trust accounting built in — critical for property managers handling owner funds
- Generous 30-day free trial lets you fully evaluate before committing
- Simple $29 + $1/unit pricing makes costs predictable and transparent
- Responsive customer support via phone, email, and live chat
Where Buildium falls short
- Essential plan caps at 150 units and charges higher per-transaction fees: $99 per bank account setup alone
- No phone support on the $62/mo Essential plan. You are limited to email and chat, which is frustrating during a billing emergency
- Growth plan at $192/mo sounds reasonable until per-unit add-on fees stack up: screening, eSign, and insurance all cost extra
- A landlord with 15 rental units will pay $62/mo for features they mostly do not need. Simpler tools like Innago or Stessa cost less
Where RentPost falls short
- No e-signing built in — lease execution requires external tools
- No native mobile app for on-the-go management
- Limited feature depth compared to larger platforms once you exceed 100 units
- Very small review count (17) makes it hard to assess long-term reliability
Who is each product built for?
Buildium
Target: 1-5000 units
Buy Buildium if you are a professional property manager running 50-5,000 residential units or HOA portfolios and need real accounting with 1099 filing. The tenant and owner portals save hours of email. Skip if you manage under 30 units, because the per-transaction fees and plan costs make simpler tools a better deal.
RentPost
Target: 1-100 units
RentPost is a solid, no-frills property management tool for small landlords and managers who specifically need trust accounting capabilities. The transparent per-unit pricing and generous 30-day trial are positives. However, the lack of e-signing, no mobile app, and limited scale make it best for small portfolios under 100 units where trust accounting compliance is a priority.
