How REI deal analyzers work
A real estate deal analyzer is a dedicated tool for stress-testing a specific property before capital goes out the door. It replaces ad-hoc spreadsheets with formulas built for the way investors actually underwrite — full PITI-based cash flow, debt service coverage, all-in project cost with points and closing, and exit-specific returns. House flippers need a net profit and ROI number that accounts for holding costs during rehab. BRRRR investors need cash left in the deal and monthly cash flow after refinance. Buy-and-hold landlords need DSCR and year-one return on equity. A purpose-built analyzer keeps the math transparent so every assumption is visible on one screen.
Every analyzer on this hub shares the same methodology. State-level data — property tax rates, transfer taxes, typical insurance premiums, attorney closing requirements, and foreclosure timelines — is pulled from authoritative public sources and used as the defaults so screening a deal in Texas versus New York versus Florida reflects the real cost differentials. A built-in stress test applies three simultaneous adverse conditions: rehab coming in 20 percent over budget, After Repair Value landing 5 percent below estimate, and the hold period extending by the state-specific foreclosure clock. Formulas are displayed on the page rather than hidden inside a black box, so you can trace every output back to the inputs that drove it.
Pick the analyzer that matches the exit you’re actually evaluating. The Flip vs. BRRRR Analyzer is the right starting point when a single property could reasonably be flipped or held as a rental. The Rental Cash-Flow Analyzer is built for long-term rentals and DSCR. The Seller Net Sheet Calculator models the seller side. The Fix-Flip Deal Analyzer is the fast resale screen: net profit, ROI, max offer, break-even ARV, holding-cost burn, and downside stress on one surface. The Airbnb & STR Calculator projects nightly revenue, platform fees, lodging tax, NOI, cash flow, and break-even occupancy. The Multifamily Calculator adds unit-level rent roll, loss-to-lease, NOI, NCF, DSCR, cap rate, and selective state underwriting pages for small apartment deals.
