Getting your first rental property is a milestone. But scaling a portfolio requires a different approach — different financing, different systems, and a different mindset. Here's how investors grow from 1 to 10+ doors.
The BRRRR Method
BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat. Instead of saving up a new down payment for each property, you recycle your capital:
- Buy: Purchase a distressed property below market value (often with hard money or cash).
- Rehab: Renovate to force appreciation and achieve market rents.
- Rent: Place a tenant to stabilize income and qualify for a conventional refinance.
- Refinance: Cash-out refinance at the new appraised value to recover your initial investment.
- Repeat: Use the recovered capital for the next deal.
Conventional Loan Limits
Fannie Mae allows up to 10 financed properties, but guidelines get stricter after 4:
| Properties Financed | Min. Down Payment | Min. Credit Score | Reserves Required |
|---|---|---|---|
| 1–4 | 15–25% | 680 | 2 months per property |
| 5–10 | 25% | 720 | 6 months per financed property |
Portfolio Loans Beyond 10 Properties
Once you exceed conventional limits, portfolio lenders (typically smaller regional banks and credit unions) can finance you based on the portfolio's overall performance. These loans aren't sold to Fannie/Freddie, so terms vary widely. Blanket loans cover multiple properties under one loan — convenient but all properties are cross-collateralized.
Systems for Scale
- Property management: Hire a PM when you hit 5+ units or when management is affecting your day job.
- Accounting software: Stessa (free) or QuickBooks — critical for tax prep and performance tracking.
- Maintenance tracking: BuildiumDoors or similar for maintenance requests and vendor management.
- Legal structure: Consider an LLC for each property or group of properties for liability protection.
- Banking: Separate business account for each entity; don't co-mingle personal and rental funds.
