Best BRRRR Calculators 2026
The BRRRR method (Buy, Rehab, Rent, Refinance, Repeat) requires analyzing two distinct phases: the acquisition/rehab phase and the long-term hold phase. A good BRRRR calculator models both — showing you how much cash you will have left in the deal after refinancing and what your post-refinance cash flow looks like. Here are the best tools for running BRRRR analysis in 2026.
What a BRRRR calculator needs to do
- Model the purchase + rehab phase — total investment (purchase + repairs + holding costs)
- Calculate post-rehab ARV — what the property appraises for after renovation
- Model the refinance — new loan amount at 75% LTV, cash-out amount, cash left in deal
- Project post-refi rental returns — cash flow, CoC return, cap rate on remaining invested capital

BRRRR-specific metrics to look for
- Cash left in deal after refi — the key metric. Ideally near $0 (you got all your money back).
- Post-refi monthly cash flow — must be positive after the higher refi loan payment.
- Post-refi CoC return — calculated on remaining cash, not total investment.
- Break-even refi LTV — what LTV would return 100% of your cash? Compare to available loan products.
The BRRRR magic number: If your total investment is $175,000 and ARV is $235,000, a 75% LTV refi gives you $176,250 — you get ALL your cash back plus $1,250. This is a "perfect BRRRR" — infinite CoC return since you have zero cash left in the deal.
