About this calculator
BRRRR (Buy, Rehab, Rent, Refinance, Repeat) is the buy-and-hold investor playbook. Buy distressed below ARV; rehab with cash or hard money; rent it out; refi at 75-80% LTV pulling out most/all of original cash; repeat with the recovered capital. The deal "works" if refi recovers ≥ 100% of cash in (zero or negative left in deal = infinite cash-on-cash return) and the monthly cash flow covers the new mortgage with margin.
Frequently asked
What's "infinite return"?+
When you recover 100%+ of cash via refi, you have $0 of your own money left invested but still earn cash flow. ROI = ∞.
Realistic LTV?+
Conventional cash-out: 75-80% on investment property. Some portfolio lenders go higher.
What if ARV is lower than expected?+
Less cash recovered. Stress-test with 90% of expected ARV.
Refi seasoning?+
Most lenders require 6 months of ownership before cash-out refi. Some allow "delayed financing" sooner.
When does BRRRR fail?+
Underestimated rehab, overestimated ARV, rates rising during deal, can't rent it out fast.
