BRRRR — Buy, Rehab, Rent, Refinance, Repeat — is a strategy for building a rental portfolio without needing fresh down-payment cash for every property. Done well, it lets you recycle the same pool of money into deal after deal. Done carelessly, it traps your capital in a property that won't appraise. The difference is almost always in the numbers you run up front.
The five steps
- Buy: purchase a property below market value, usually one that needs work, often with short-term or cash financing.
- Rehab: renovate to force appreciation — raising both the property's value and the rent it can command.
- Rent: place a quality tenant so the property produces income and can qualify for long-term financing.
- Refinance: replace the short-term loan with a long-term mortgage based on the new, higher value, pulling much of your invested cash back out.
- Repeat: take that recovered cash and do it again.
Why the after-repair value is everything
The whole strategy hinges on the after-repair value (ARV). Your refinance is based on the appraised value once the work is done, so if the ARV comes in lower than you projected, you pull less cash out and leave money stuck in the deal. Investors who get burned on BRRRR almost always overestimated ARV, underestimated the rehab, or both.

Run the exit before you buy
Before you make an offer, model the finished property as a rental: what will it appraise for, what rent will it command, and what will the new mortgage payment be? If the refinanced loan leaves the property cash-flow negative, the deal doesn't work no matter how clever the acquisition was. Treat the rent-and-refinance step as the real test, not an afterthought.
The math is the same discipline as any rental analysis — cap rate, cash flow, and cash-on-cash on the post-rehab numbers — plus an honest rehab estimate and a conservative ARV. Get contractor bids, pull real comps, and pad your budget. The strategy rewards patience with the spreadsheet far more than optimism about the renovation.
