How the BRRRR math works

Total cash invested = purchase price + closing costs + rehab + holding costs (assuming the purchase and rehab are paid in cash or with a short-term loan you repay at refinance). At refinance the lender sizes the loan on the appraised after-repair value: loan = ARV × LTV. Net cash out = loan − refinance closing costs. Cash left in the deal = total cash invested − net cash out.

If cash left is zero or negative you recovered all your capital (an "infinite" cash-on-cash return). Then check the rent still covers the bigger mortgage: post-refi cash flow = rent × (1 − vacancy) − operating expenses − new P&I.

Common pitfalls

FAQ

What does BRRRR stand for?

Buy, Rehab, Rent, Refinance, Repeat — a strategy of recycling the same capital into multiple rentals.

What is a good capital recovery percentage?

100% means you got all your cash back. Many investors are happy with 75%+ if cash flow stays positive.

What LTV do lenders use for a cash-out refinance?

Commonly 70–80% of appraised value for investment properties; check with your lender.

Is a BRRRR with cash left in the deal a bad deal?

Not necessarily — it simply behaves more like a buy-and-hold; judge it by the cash-on-cash return on the cash left in.
