Running the numbers is step one. A deal that pencils out still depends on an accurate ARV, real contractor bids, and financing you can actually get. Use this to screen deals fast and to structure the ones worth pursuing.
How the deal analysis works
The calculator starts from the two numbers you control at acquisition — the purchase price and the construction budget (cost per square foot times square footage) — and compares their sum, the project cost, against the property’s after-repair value. Subtract sales and property costs (agent commissions, closing, taxes — roughly 9% of ARV) and what’s left is your potential profit before any financing carry. The margin that profit represents drives the deal grade, from a full-BRRRR 25%+ down to a thin retail sub-10%.
Financing is modeled in two stages, the way most flips and BRRRR deals are actually funded. First a short-term hard-money loan carries the acquisition and rehab: the calculator totals the down payment, points, fees, monthly carry over your expected hold, and a reserve for surprises into the real cash you need on hand — which is almost always more than the down payment alone. Then a takeout refinance replaces that short-term loan with a long-term mortgage sized off the ARV, and the BRRRR cash-flow figure shows what monthly rent is left after the mortgage (PITI) and property management.
What this page deliberately does not do is rank one deal against another. Once a deal survives the screen here, the cash-on-cash return calculator puts its profit next to the cash and the months it ties up, which is what makes two very different deals comparable.
