Run the numbers before you make the offer. REI Toolkit is the deal-analysis kit for real estate investors who'd rather walk away from a bad deal than learn about it later. Flippers, landlords, BRRRR investors, and wholesalers — every tool you reach for between "I might offer on this" and "I'm signing." No subscription. No account. Works offline. THE TOOLKIT • Flip Calculator — purchase, rehab, holding, and selling costs vs. ARV. Real ROI, not the back-of-the-napkin version that ignores six months of insurance. • New Construction — ground-up and teardown spec builds: land, hard and soft costs, and construction financing against ARV, down to cost per square foot. • 70% Rule / MAO — the wholesaler's max allowable offer, ready before the seller hangs up. • Rental Property — cash flow, cash-on-cash, NOI, and the 1% rule check on every deal. • Cap Rate — quick screen with market-tier interpretation, so you know whether to bother modeling the rest. • BRRRR — tracks cash-left-in-deal so you know when you've truly recycled your capital. • Amortization — full loan schedule, total interest, payoff modeling. • Refinance Break-Even — the real break-even, including closing-cost drag. • Wholesale Offer — max offer to seller, after the end buyer's MAO and your assignment fee. • DSCR — debt service coverage ratio with lender-tier interpretation. See if the deal funds before you write the offer. • GRM — gross rent multiplier for fast screening before a full analysis. WHY REI TOOLKIT • Start free, unlock once.
