Cash-Out Refinance Mechanics on a DSCR Loan

The mechanics, step by step

A cash-out refi replaces your current loan with a new, larger one sized against the property's appraised value, up to a maximum loan-to-value the lender allows. The new loan pays off the old balance first; whatever's left over — minus closing costs — is the cash that comes to you at closing.

Because the loan amount goes up, the new PITIA goes up too, even if the rate hasn't moved. The DSCR is then recomputed on current market or in-place rent against that new, higher PITIA. This is the step people skip in their head-math: the ratio that qualified you at purchase is irrelevant here — only the post-refi ratio matters.

Why the ratio can slip even when rent hasn't dropped

Rent staying flat doesn't guarantee the ratio holds after a cash-out refi, because the denominator just grew. A deal that cleared 1.25 on the original loan can land at 1.05 or dip under 1.0 on the new, larger balance — same rent, bigger payment.

1. Get the current appraised value, not the purchase price, as your LTV base.
2. Calculate the max cash-out loan amount at the lender's LTV cap for your property type.
3. Build the new PITIA at current live rate assumptions, not the rate on your existing note.
4. Divide current market or in-place rent by the new PITIA — that's the ratio that has to clear the floor.

When cash-out still pencils

Cash-out refis work best when the property has appreciated meaningfully since purchase and/or rent has risen enough to absorb the bigger payment. Pulling a smaller amount than the max allowed — rather than maxing out LTV — is often the difference between a ratio that clears the floor and one that doesn't.
