BiggerPockets

BiggerPockets is a real estate investing community, podcast and publisher. Wikipedia credits it with coining the BRRRR acronym, and it published the book that laid the strategy out as a repeatable process. Much of the vocabulary BRRRR investors use, from the 70% rule to the infinite return, spread through its forums.

The strategy predates the name. Investors have bought, improved and refinanced rentals for as long as cash-out refinancing has existed. What BiggerPockets added was a checklist, a large audience trading deal numbers, and a set of rules of thumb that made the method teachable.

Rules of thumb are where to be careful. The 70% rule and the infinite return were calibrated in a market with 4% mortgage rates and cheap distressed inventory. At 7% rates the refinance still returns the cash if the purchase was right, but the rental afterward is thinner than the examples from a decade ago. The method holds; the numbers have to be run fresh.

BiggerPockets teaches brrrr as five steps: buy under market, rehab to raise value, rent the finished unit, refinance out of the short-term loan, then repeat with the cash that comes back. Its forums and podcast spread the acronym, and the book Buy, Rehab, Rent, Refinance, Repeat by David Greene laid the steps out as a process.

The 70% rule it popularized caps all-in cost at 70% of after-repair value, so on a $500,000 arv that is $350,000 for purchase plus rehab. Its infinite return idea means the refinance hands back every dollar you put in; at 75% ltv a $500,000 arv pays out $375,000, so total project cost has to sit under that figure less refinance costs. Both rules were calibrated at 4% mortgage rates, so at 7% the refinance can still return the cash while the rental afterward is thinner.
