AppFolio is the industry-standard property management platform — about 18,000 customers, deep accounting, integrated payments, mature integrations. It's also not built for operators under 100 units. The minimum monthly bill is $280, the per-unit cost is $1.40-$3 depending on tier, and implementation takes 1-2 weeks. If you're running 5-50 doors, you're paying for capacity you don't use.
Here are the five real alternatives at small scale, with honest tradeoffs.
1. Buildium — $58 + $1.50/unit
What it is: The default mid-market PM platform owned by RealPage. ~16,000 customers. Solid accounting, e-signature workflows via DocuSign, owner portal, established tenant mobile app.
Strengths. Cheapest of the "real" PM platforms at small scale. Built-in 1099 generation. 10+ years of debugged workflows. Mature support team. RealPage-owned so it isn't going anywhere.
Weaknesses. UI hasn't substantially changed since 2018. No AI tenant-inbox automation — every email is manual. Limited state-specific legal notices (Utah only has rough Utah templates if you know to look). Onboarding takes 5-10 business days.
Math at 30 units: $58 + (30 × $1.50) = $103/month.
Pick Buildium if: Cost is your single biggest criterion AND your inbox volume is low enough that AI automation isn't a needed win.
2. DoorLoop — $59 + $0.99/unit
What it is: Newer entrant (founded 2019), mobile-first design, focused on small-to-mid operators. Growing fast.
Strengths. Modern UI, the closest to a 2025-vintage design among traditional PM tools. Strong mobile app for both operators and tenants. Solid accounting basics. Public API documentation. Cheaper per-unit than Buildium.
Weaknesses. No AI agent for tenant inbox. Customer service is hit-or-miss according to G2 reviews. The reporting depth doesn't match Buildium or AppFolio yet. Some integrations (Yardi, RealPage) aren't available.
Math at 30 units: $59 + (30 × $0.99) = $89/month.
Pick DoorLoop if: You want a modern UI without the AI layer, and your operation is mostly straightforward residential.
3. TenantCloud — free up to 75 units (basic), $15-$35/month for paid tiers
What it is: Freemium PM platform — the only one in this list with a real free tier.
Strengths. Free. Genuinely usable at small scale (1-10 units) without paying anything. Online rent payments included. Listings syndication to Trulia, Apartments.com, others. The free tier is supported indefinitely; not a 30-day trial.
Weaknesses. Feature depth is shallow on the free tier. Reporting is basic. Accounting export to QuickBooks costs extra. The UI feels like a 2014-era SaaS app. No AI.
Math at 30 units: Free tier OR $35/month depending on features.
Pick TenantCloud if: You're a small landlord (1-15 units) and your budget is genuinely $0/month for software. Worth knowing about even if you graduate from it later.
4. RentRedi — $12/month flat (landlord tier)
What it is: A landlord-focused tool (not a PM-focused tool). Used by 30,000+ landlords for tenant screening, rent collection, maintenance requests.
Strengths. Cheapest in the list. Flat pricing — doesn't scale with units. Tenant portal mobile app is well-built. TransUnion integration for screening.
Weaknesses. Built for landlords managing their OWN property, not for PM companies managing on behalf of others. No owner reporting. No multi-user team support. Accounting is minimal.
Math at 30 units: $12/month flat.
Pick RentRedi if: You're a self-managing landlord, not a PM company. If you're managing for outside investors, this isn't built for you.
5. Summit — $497-$2,497 flat (AI-first PM platform)
What it is: AI-first PM platform. Replaces 80% of the tenant-inbox work with an AI agent that reads every email, looks up the lease and balance, and replies in under a minute. Safety gate holds legal threats, emergencies, and rent-withholding signals for human review.
Strengths. Only platform with real AI tenant-inbox automation. State-aware legal notices for 10 states out of the box. Per-property compliance overrides for multi-state operators. STR (Airbnb / VRBO) iCal sync + auto-cleaning dispatch built in. Modern UI. Flat predictable pricing.
Weaknesses. Pre-launch — zero paying customers as of June 2026. Doesn't replace your accounting system (works alongside QuickBooks / Xero). No built-in payment processor — uses Stripe Connect. No native mobile app (PWA only). Smaller team than AppFolio / Buildium / DoorLoop.
Math at 30 units: $797/month flat (Boutique tier, 11-30 units).
Pick Summit if: The inbox is what eats your day, you operate across multiple states, you have STR units mixed with LTR, or you value flat predictable pricing over per-unit math.
Decision matrix at 30 units
| Tool | $/mo at 30 units | Right for |
|---|---|---|
| RentRedi | $12 | Self-managing landlord |
| TenantCloud (paid) | $35 | 1-15 units, tight budget |
| DoorLoop | $89 | Modern UI, no AI |
| Buildium | $103 | Cheapest established PM |
| AppFolio | $322-$370 | 100+ units, deep accounting |
| Summit | $797 | Inbox-heavy ops + multi-state |
If your monthly bill is the only thing that matters, Buildium or DoorLoop wins. If your time on tenant emails is the bottleneck — Summit pays for itself in under 4 hours of saved operator time per month. Run the math for your portfolio →
Honest read: most operators evaluating us pick between Buildium-for-cost and Summit-for-time-back. Picking us when cost is your only criterion is the wrong choice. See our Buildium comparison page for the full breakdown.
