The BRRRR & Fix-and-Flip Deal Analyzer
A free spreadsheet that underwrites your next deal before you write an offer — rehab budget, Maximum Allowable Offer, DSCR, cash-on-cash return, and a 5×5 sensitivity grid, all in one workbook. Built for investors evaluating a fix-and-flip, a BRRRR, or a straight rental purchase.
Six tabs, one workbook.
Everything you need to underwrite a fix-and-flip or a BRRRR deal from purchase to refinance — no other software required.
Start Here
Enter the property, purchase price, and your financing assumptions once — every other tab pulls from these inputs automatically.
Rehab Budget
Line-item your renovation costs by category, with a contingency line built in so surprises don’t blow up the deal.
Fix & Flip
Models your resale proceeds and holding/selling costs, then calculates your Maximum Allowable Offer (MAO) — the ceiling price you can pay and still hit your target margin.
BRRRR
Models the post-rehab refinance: your DSCR, how much cash is left in the deal, and your cash-on-cash return once the property is rented.
Sensitivity
A 5×5 sensitivity grid that stress-tests the deal across a range of after-repair value and rehab-cost outcomes — so you can see your margin for error before you’re under contract.
Glossary
Plain-English definitions for every term in the workbook — MAO, DSCR, cash-on-cash, ARV, LTV, and more — so nothing is a guess.
Who it’s for
Real estate investors evaluating a fix-and-flip, a BRRRR (buy, rehab, rent, refinance, repeat), or a straight rental purchase — whether it’s your first deal or your fiftieth. The workbook is a planning tool: it does the arithmetic so you can compare deals on the same terms and know your numbers before you negotiate.
Why we give this away. Loanatik helps investors explore DSCR and other business-purpose financing where available, and offers fix-and-flip, bridge, and private/hard-money lending for investors in Arizona. We’d rather work with investors who underwrite a deal properly before they call us. Run your numbers here first; if they pencil, we’re a phone call away.
