HOW BRRRR WORKS
BRRRR — Buy, Rehab, Rent, Refinance, Repeat — lets you recycle the same capital across multiple rentals. You buy below value, rehab to force appreciation, rent it, then refinance based on the new (higher) value to pull your cash back out. The lender lends a percentage of ARV (the LTV); if that loan is bigger than what you put in, you recover all your cash and your return is effectively infinite. The two traps: an ARV that doesn't appraise as high as you hoped, and a refinance payment that turns cash flow negative. Be conservative on both.
