Quick Answer: Rent Manager runs $8,000–$14,000/year for 300 units (flat pricing, no per-unit scaling). AppFolio runs $12,000–$22,000/year for 300 units when transaction fees are included. Rent Manager wins on price, especially for operators who prioritize accounting depth over UI modernity. Custom software breaks even with AppFolio around year 4–5 for 300 units and permanently eliminates fee scaling as you grow.
The Rent Manager vs AppFolio decision comes up constantly among 200–600 unit operators. AppFolio gets the press and has the polished interface — but Rent Manager has a reputation for deeper accounting and, often, lower actual cost for mid-size portfolios. This guide breaks down what each platform actually costs at 300 units, where each wins and loses, and when custom software enters the equation.
What Rent Manager Actually Costs at 300 Units
Rent Manager pricing is not published publicly and varies by package, but based on operator contracts in the 200–500 unit range:
Rent Manager Online (cloud): approximately $400–$700/month for 200–400 units, flat pricing tiers
Annual cost: $4,800–$8,400/year base
Implementation: $500–$2,000 one-time
Add-on modules: $50–$200/month each (e.g., Tenant Web Access, Screening, Payments)
With typical add-ons, a 300-unit operation on Rent Manager runs $8,000–$14,000/year total. That's meaningfully lower than AppFolio for the same portfolio size.
What AppFolio Actually Costs at 300 Units
Core: $1.40/unit/month × 300 = $420/month = $5,040/year base
Plus: $3.00/unit/month × 300 = $900/month = $10,800/year base
Payment processing: 2.99% on ~$540K/year collected (90% of 300 units × $1,500 avg) = $16,146 in fees
Total AppFolio Core for 300 units with standard transaction volume: $12,000–$18,000/year. AppFolio Plus: $20,000–$26,000/year. Those payment processing fees are the killer for AppFolio at every portfolio size.
Side-by-Side Comparison
Where Rent Manager Wins
Accounting depth
Rent Manager was built by accountants for property managers. General ledger, job costing, bank reconciliation, and financial reporting are significantly more sophisticated than AppFolio. If your operation has complex accounting needs — multiple entities, owner splits, commercial leases alongside residential — Rent Manager handles it better.
Flat pricing at scale
AppFolio's per-unit model means every new unit adds cost. Rent Manager's flat-tier structure means growing from 300 to 400 units doesn't automatically increase your bill. For growing portfolios, this is a meaningful long-term advantage.
Total cost at 300+ units
Once you factor in AppFolio's transaction fees, Rent Manager is almost always cheaper at 300+ units. The gap widens further as you grow.
Where AppFolio Wins
Modern user interface
AppFolio's UI is significantly more modern than Rent Manager's. Tenants and owners who interact with AppFolio's portals get a better consumer-grade experience. If your market is younger tenants who expect a Venmo-quality payment experience, AppFolio's front-end quality matters.
Mobile app
AppFolio's mobile app for property managers and maintenance staff is stronger. If your team does significant field work, AppFolio's mobile experience is noticeably better than Rent Manager's.
Implementation simplicity
AppFolio's setup is faster and more guided. For operators switching from paper-based systems or from Buildium, AppFolio's onboarding is less intimidating than Rent Manager's more complex configuration.
When Custom Software Is the Right Third Option
For 300-unit operators planning to operate for 5+ years, custom software deserves serious evaluation. Build cost: $70,000–$110,000. Annual maintenance: $8,000–$12,000. Build timeline: 4–6 weeks. Break-even against AppFolio: year 4–5. Break-even against Rent Manager: year 6–7. After break-even, you save $6,000–$14,000/year permanently.
The other reason to consider custom: neither Rent Manager nor AppFolio can be built exactly to your workflow. Custom means your maintenance dispatch process, your owner reporting format, your specific lease terms, your exact vendor payment structure — all built in, not worked around.

The Decision Framework
Choose Rent Manager if:
Accounting depth is a priority and you're doing complex financial management
You're growing past 300 units and want flat pricing that doesn't scale with your portfolio
Budget is a primary concern and AppFolio's UI premium isn't worth it to you
Choose AppFolio if:
Modern UI and mobile experience matter to your team and your tenants
You want faster, simpler implementation
You're in the 200–400 unit range and not yet at the scale where per-unit fees become painful
Explore custom if:
You're managing 300+ units, planning 5+ years of operation, and spending $12,000+/year on software fees
Frequently Asked Questions
Can I import data from AppFolio to Rent Manager (or vice versa)?
Both platforms support CSV data exports for tenant, lease, and financial data. Neither has a direct import tool from the other — you'll need to clean and reformat exported data before importing. Budget 3–4 weeks for data migration and validation, plus 3–4 weeks of parallel operation before full cutover.
Does Rent Manager charge transaction fees?
Rent Manager's payment processing fees vary by payment method: ACH is typically $1–$2/transaction flat, credit card is 2.75–2.99%. This is different from AppFolio's percentage-of-transaction model — for high-value rent payments, Rent Manager's flat ACH fee is significantly cheaper.
Is Rent Manager hard to learn?
Steeper learning curve than AppFolio, yes. Rent Manager's interface and workflow are more traditional accounting software than modern SaaS property management. Most teams are fully proficient within 4–6 weeks. If you have staff with general accounting software experience, the transition is smoother.
Managing 300 units and spending $15,000+/year between platform fees and transaction costs? Custom software almost certainly breaks even faster than you'd expect. We'll run the specific numbers for your operation — no commitment required.
