DSCR cash-out math: how much equity you can actually pull

Every cash-out guide opens with the same line: lenders will go to 75 percent loan-to-value, so take 75 percent of the value, subtract your balance, and that is your check. On a DSCR loan that arithmetic is frequently wrong. The loan is underwritten against the property's rent, and the rent sets a second ceiling that often binds before the LTV cap does. The number you can actually pull is the lower of the two, minus costs, and most investors discover which one governs only after the appraisal lands.

This piece walks through that math with a single worked example, then covers the pieces that move it: cost-basis limits, rate and point trade-offs, interest-only structure, and use-of-proceeds paperwork. For the general mechanics of the product, start with our cash-out DSCR refinance overview; this is the numbers-first follow-up.

Two ceilings, not one

A DSCR cash-out loan has to clear two tests at the same time. The first is the leverage cap: typically 70 to 75 percent LTV on cash-out for a single-family rental with a mid-700s score, stepping down to 65 or 70 percent for sub-680 scores, 2-4 units, or non-warrantable condos. The second is the coverage floor: the property's rent divided by its full PITIA, which most lenders want at 1.00 to 1.25 depending on the tier and the cash-out amount.

Because cash-out raises the loan balance, it raises the payment, which lowers the ratio. A property that cleared 1.40 on its old, smaller mortgage can drop under 1.10 on the new one. The more equity you ask for, the closer you run to the coverage floor. For a refresher on how the ratio is built, see how DSCR loans work.

A worked example

Take a single-family rental appraised at $450,000 with a $210,000 payoff. Market rent from the appraisal's rent schedule is $3,100. Property taxes run $410 a month and insurance $165, so escrow items total $575.

At 75 percent LTV the maximum loan is $337,500. On a 30-year amortizing note at an illustrative 7.25 percent, principal and interest is about $2,302, so PITIA is $2,877 and the DSCR is 1.08. Against a 1.20 floor, that fails.

Work backward instead. At a 1.20 floor, PITIA can be no more than $2,583 ($3,100 divided by 1.20). Subtract the $575 in taxes and insurance and the maximum principal and interest is $2,008, which supports a loan of roughly $294,000 at 7.25 percent. That is a 65.4 percent LTV, not 75.

With closing costs near 3 percent of the loan ($8,800), net cash to the borrower is about $75,000. Had the LTV cap governed, the check would have been closer to $117,000. The $42,000 gap is entirely a rent problem, and no amount of equity fixes it.

Interest-only changes the ceiling

The fastest legal way to raise the coverage-limited loan amount is to change the payment structure. On the same property at an illustrative 7.50 percent interest-only, the 1.20 floor allows a $2,008 payment, which supports a loan of about $321,000. Net of 3 percent costs, the borrower nets close to $101,500, roughly $26,000 more than on the amortizing note.

The trade is real: the interest-only rate usually carries a 0.125 to 0.375 point premium, the balance does not decline during the IO period, and the payment resets higher when amortization starts, commonly after 10 years. Our interest-only DSCR guide covers the reset math. For a buy-and-hold investor planning to refinance or sell inside that window, IO is often the right tool for a cash-out that otherwise fails coverage.

Cost basis versus appraised value

Seasoning rules decide which value the lender lets you use. Many lenders allow the full appraised value after 6 to 12 months of ownership. Inside that window, the cap often switches to the lesser of appraised value or purchase price plus documented improvements, and some lenders cap the loan at the original acquisition cost until the seasoning clock runs out.

That matters most for BRRRR-style buyers pulling money out after a rehab. If you bought at $240,000 and put $60,000 into the property, a lender using cost basis sees $300,000 even if the appraisal says $380,000. At 70 percent, the cap is $210,000 rather than $266,000. Know your lender's seasoning rule before you order the appraisal, because the delta can be the whole deal.

Rate, points, and the real cost of the cash

Cash-out typically prices 0.25 to 0.50 points of rate above a purchase or rate-and-term loan with the same score and LTV, and pricing steps up again as LTV passes 70 percent. Add origination of 1 to 2 points, appraisal and rent schedule near $700 to $1,000, title and recording, and a prepayment penalty structure that usually runs 5-4-3-2-1.

Run the cost of the capital before you close. Take the example above: the new loan adds $84,000 of debt over the old balance, which costs roughly $6,090 a year in interest at 7.25 percent. Against the $75,000 you net, that is an 8.1 percent pre-tax cost of money. If the next property returns less than that after expenses, the cash-out destroys value. Use the refinance calculator to model the loan before you apply.

Where the equity-rich markets fit

Cash-out math works best where rent-to-value ratios are high, because strong rent lifts the coverage ceiling. In the Midwest, where rents commonly run 0.8 to 1.0 percent of value, the coverage test rarely binds and LTV governs. Investors holding appreciated stock in Columbus or Indianapolis often find they can reach the full 75 percent cap at a 1.15 to 1.25 DSCR. In coastal or high-price markets with rents near 0.4 to 0.5 percent of value, coverage is almost always the binding constraint and the usable LTV falls into the 50s. State rules matter too: property tax levels in Ohio shift the PITIA denominator materially compared with lower-tax states, so verify the actual tax bill rather than using a rough estimate.

Use of proceeds and documentation

Because DSCR loans are business-purpose, lenders ask for a signed business-purpose affidavit and often a use-of-proceeds statement. Proceeds used to buy another investment property are never an issue. Proceeds used for personal spending can turn a business-purpose loan into a consumer-credit problem, so most lenders prohibit it in writing. Keep the paper trail clean: wire the funds to the entity account that holds the property, then move capital to acquisitions from there.

Expect reserves of 6 to 12 months of PITIA on the new payment, and sometimes a requirement that the cash-out proceeds themselves cannot count toward reserves. Compare how different programs treat these rules in the lender directory before you commit to an application; two lenders can offer the same rate and very different net proceeds.

Before you order the appraisal

Do the coverage math first. Take the rent from your current lease or a broker opinion, add your real taxes and insurance, and solve for the largest loan that clears a 1.20 ratio at today's pricing. Compare that to 70 or 75 percent of your expected value. Whichever is lower is your real budget, and the gap between them tells you whether interest-only, a rent increase, or a longer wait for seasoning is worth pursuing before you spend $800 on an appraisal.
