Managing a triplex or fourplex manually — spreadsheets, paper receipts, reminder notes — works for about 6 months. Then a tenant's rent check bounces, another tenant submits a maintenance request, and you can't find last year's insurance declarations.
Property management software solves this. For small multifamily (2–4 units), you don't need enterprise software. You need something that handles rent collection, basic accounting, and tenant communications. Here's what's actually out there.
The Big Three: Buildium, Appfolio, Rent Manager
Buildium (by AppFolio)
- Cost: $299–$649/month for small portfolios (2–4 properties)
- Strengths: Rent collection integrated, tenant portal, maintenance tracking, simple accounting
- Weakness: Overkill for 2-unit self-managed; better for 5+ units or if you're managing for other owners
- Best for: Growing self-managers planning to scale
AppFolio (higher-tier Buildium)
- Cost: $599–$2,000+/month
- Strengths: Full CRM, accounting integration, marketing tools
- Weakness: Built for management companies, not individual investors
- Best for: Professional property managers with 20+ units
Rent Manager
- Cost: $39–$99/unit/month
- Strengths: Highly customizable, tenant screening, maintenance request workflows
- Weakness: Older interface, steeper learning curve
- Best for: Experienced landlords managing multiple properties
The Lean Options: Honeywell, Landlord Studio, Avail
Avail (by Apartment List)
- Cost: Free basic; $19–$39/month for premium
- Strengths: Simple, includes rent collection and e-pay, lease templates, free tier is genuinely useful
- Weakness: Limited to basics; no advanced accounting
- Best for: First-time landlords, 1–4 units, who don't want to spend money yet
Landlord Studio
- Cost: $15–$30/month for unlimited units
- Strengths: Flat fee regardless of unit count, expense tracking, tax reporting
- Weakness: No tenant portal or online rent payment built-in
- Best for: Self-managed investors focused on expense tracking and taxes
Rental Tracker (for spreadsheet lovers)
- Cost: Free (you build it yourself) or $0–$50/month for a pre-built template
- Strengths: Customizable to your exact workflow, you own the data
- Weakness: Requires discipline; easy to fall behind
- Best for: DIY type-A investors comfortable with spreadsheets
The Penny Pincher's Setup
If you have 2–3 units and want to spend nothing upfront:
- Rent collection: Venmo, PayPal, or Zelle (free, fast, documented)
- Tenants & leases: Google Docs shared folder or Dropbox
- Maintenance requests: Google Form that auto-logs into a spreadsheet
- Accounting: Spreadsheet with monthly rent, expenses, and depreciation calculated
- Tax filing: Hand everything to your CPA or use TurboTax Self-Employed
Cost: $0/month. Time: 2 hours/month. Works if you're disciplined.
What to Look For
- Rent collection: Can tenants pay online? What's the fee? (Most charge $0–$3/transaction or 2.5% transaction fee)
- Tenant communications: Can you send messages, notices, and documents through the platform?
- Maintenance tracking: Can tenants request repairs? Can you see status in one place?
- Accounting: Does it export to QuickBooks or your CPA's software?
- Mobile app: Can you check in on things while away?
- Lease templates: Are they state-specific and legally solid?
The Real Talk
Most landlords don't use dedicated property management software until they have 5+ units or are managing for 3+ owners. If you're self-managing a duplex, a well-organized Google Drive and Venmo/Stripe for rent collection is enough.
If you're self-managing a fourplex or managing properties for others, invest $30–$100/month in Avail or Landlord Studio. The time you save on rent collection, expense tracking, and tenant requests pays for itself in hours saved, plus you'll actually file taxes correctly.
At $15–$40/month, there's no reason not to use something. The spreadsheet era is over.
