Buildium gates AI to Growth+. Rentbase includes it on every tier.
Buildium is a well-established mid-market PMS — strong double-entry accounting, owned by RealPage, with Lumina AI gated to its Growth and Premium tiers. On maintenance, Lumina summarizes and tracks work orders and closes the loop, but intake routing is rule-based and deeper triage runs through Marketplace bolt-ons (Haven, STAN, Inspectr). Its drafting tools (Write with Lumina) start at Growth ($192/mo); the agentic Lumina AI Workforce and AI Bill Scan are Premium only, from $400/mo. Rentbase leads with maintenance — AI triage, always-on emergency detection, two-way tenant messaging, and vendor coordination in Starter at a flat $49/mo — and grows into AI lease reading, the 30/60/90 renewal pipeline, vacancy briefs, and owner reports in Pro at $99/mo. Run Rentbase alongside Buildium for the AI workflows it gates, or replace it entirely — and Rentbase is independent, not RealPage-owned. (Buildium claims per its public pricing, as of June 2026.)
When to add Rentbase to your stack
Two ways to use Rentbase with Buildium in the picture. Most operators start with the alongside path.
Path 1: Use Rentbase alongside Buildium (most common)
Keep Buildium for accounting depth and the workflows you use today. Add Rentbase for AI maintenance triage, emergency detection, and two-way tenant messaging — at a flat $49/mo, no Growth or Premium upgrade required — with lease and owner AI in Pro when you're ready. A good fit if: you're happy with Buildium's accounting and don't want to upgrade to Growth/Premium for AI; you want AI maintenance triage and tenant messaging in the entry tier; you want AI-drafted narrative owner reports Buildium doesn't have (Pro); you want flat per-firm pricing for the AI layer; you prefer an independent vendor for the AI layer (not RealPage-owned).
Path 2: Use Rentbase to replace Buildium (for switchers)
Migrate your portfolio off Buildium. Pair Rentbase with standalone accounting (QuickBooks, Xero, or similar) if you need accounting depth Rentbase doesn't cover. Starter is $49/mo at any portfolio size. A good fit if: you're actively shopping PMS replacements; Buildium's tiered + per-unit + transaction-fee pricing is opaque or expensive; you want an independent platform, not RealPage-owned; you'd rather pair with standalone accounting than bundle; you're willing to migrate your portfolio (15 min with the wizard).

Common questions
Can I migrate from Buildium to Rentbase?
Yes. Many operators run Rentbase alongside Buildium — Buildium for accounting depth, Rentbase for the AI workflows. If you want to fully migrate, export your data from Buildium (CSV) and use Rentbase's import wizard. The AI handles column mapping. You can also run both for a transitional period.
Does Rentbase have Buildium's accounting depth?
Different categories of software. Buildium is a records platform — built around deep double-entry accounting and comprehensive ledger management. Rentbase is action-led — built to do the operational work that creates the data: AI lease extraction, AI maintenance triage, AI-drafted communications, AI owner reports. Rentbase covers the core financial workflows operators run day-to-day (payment tracking, management fee calculation, expense tracking, owner statements, NOI reporting). Buildium has deeper double-entry accounting and longer-established accounting workflows. Many operators run Rentbase alongside their existing accounting (Buildium, QuickBooks, or similar) and use Rentbase for the AI operational layer. Pick based on what work matters most.
Is Rentbase really independent?
Yes. Rentbase is not owned by RealPage or any other PMS conglomerate. We're a standalone company building action-led property management software. Independence matters because product roadmap and pricing decisions aren't subject to a parent company's broader portfolio strategy.
