How the fix and flip and BRRRR calculator works
This tool runs two investor strategies. For flips it applies the 70% rule: max offer = (after-repair value x 0.70) - repair costs, then estimates profit and ROI. For BRRRR (buy, rehab, rent, refinance, repeat), it models a cash-out refinance against the ARV to show how much of your capital you can pull back out.
With a $450,000 ARV and $60,000 in repairs, the 70% rule caps your offer at $255,000 ($315,000 - $60,000). Buy at $300,000, spend $60,000 on repairs, and add $40,000 in holding and selling costs, and a $450,000 sale nets about $50,000. A 75% refinance instead returns $337,500 in cash.
South Florida's older housing stock and strong resale demand make both strategies viable, but thin margins punish overpaying. The 70% rule enforces discipline on your offer, and the BRRRR refinance math shows whether you can recycle capital into the next deal. Running the numbers first keeps a promising flip from turning into a loss.
