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 finances real estate investors — DSCR and other business-purpose loans nationwide, and 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.
