A DSCR loan on a fix and flip project is usually the wrong tool and the loss case shows exactly why.
Take a property bought at 180k with a 30k cosmetic scope and a 270k ARV. A DSCR loan underwrites to the rent the property would generate as a rental, so the lender wants to see that the monthly rent covers the debt service, typically at a ratio of 1.1 or 1.25. A vacant property mid-renovation produces zero rent. Some lenders will use projected market rent, but that projection is based on the finished, stabilized condition, and during a 90 day flip the property never reaches that condition. What tends to happen is the loan closes on the as-is value, the borrower cannot draw against rehab costs the way a dedicated fix and flip loan allows, and the capital structure forces them to fund the 30k scope out of pocket or through a separate line. The math on that is fine if you have the liquidity. If you do not, the project stalls and holding costs compound on a loan that was priced for a buy-and-hold, not a short exit.
A dedicated fix and flip loan, usually hard money or a short term bridge product, prices differently. The rate is higher, often 10 to 14 percent annualized depending on the lender and the market, but it is structured for the actual use. You get a purchase advance plus a rehab holdback drawn in stages as work completes, and the term is 6 to 12 months with an exit at resale. On the 180k purchase with a 30k scope, the lender might advance 85 percent of purchase and 100 percent of rehab costs, so roughly 153k at close and 30k released through draws. Total loan cost over 90 days at 12 percent annualized is around 4,600 dollars on the funded balance, plus origination of 1 to 2 points. That is the real cost to compare against a DSCR product, and DSCR on a flip often has origination too, with a prepayment penalty that bites hard on a 90 day hold.
The scenario where DSCR makes sense in this neighborhood is a cosmetic project where the plan from day one is to refinance into a rental at completion. In that case the DSCR loan funds the purchase and you carry the rehab separately, then the stabilized rent covers the debt service and you hold. That is a BRRRR structure, not a flip, and conflating the two is where the loss usually lives.
What is the exit on your project, a resale or a potential hold, because that one decision changes which loan type is even on the table?
