The Quick Read: It depends on how much cash you take out, but the ratio usually falls by less than the loan grows, because rent stays flat while only the principal-and-interest part of your payment scales up. Taxes, insurance and association dues don’t grow with the balance, so they cushion the drop.
- Pulling 25% more balance can cut a 1.15x file to roughly 0.96x. Pulling 15% more leaves it near 1.03x. These are illustrative figures, not market data.
- The lender recalculates coverage on the new, larger payment, not on your old one.
- Two tests apply at once: leverage (the 75% cash-out LTV ceiling on investment property) and rent coverage. The tighter one sets your cash.
- Clearing 1.00 is not the same as positive cash flow. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

What Does DSCR Actually Measure?
DSCR is the debt service coverage ratio. For a residential rental, it is the property’s qualifying monthly rent divided by its full monthly obligation. A ratio of 1.00 means the rent exactly covers the payment. Above 1.00 means the rent covers it with room to spare.
Scotsman Guide describes the calculation as gross monthly rent divided by monthly expenses such as principal and interest, insurance and association fees. It also notes that appraiser rental surveys supply the rent figure. The same piece points out that a higher ratio means less risk for the lender.
The full obligation is called PITIA: principal, interest, taxes, insurance and association dues. Most residential DSCR files use this rent-over-PITIA version.
You may also see a corporate version of the formula, which divides net operating income by total debt service. It subtracts operating costs first. Residential DSCR programs on one-to-four-unit rentals use the simpler rent-over-PITIA math. That difference explains why a commercial lender’s 1.25x benchmark doesn’t automatically apply to your rental.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
Why Does a Cash-Out Refinance Lower Your DSCR Ratio?
A cash-out refinance replaces your current loan with a larger one and hands you the difference. The bigger balance carries a bigger principal-and-interest payment. The rent doesn’t change. Same numerator, larger denominator, lower ratio.
Here is the part most investors miss. Only one slice of PITIA scales with the loan. Taxes, insurance and association dues sit in the payment whether you owe a little or a lot. So when the balance grows by a given percentage, the total obligation grows by less than that percentage.
Compare two properties. One has a payment dominated by principal and interest. The other has a heavy tax and insurance load. Pull the same percentage of extra balance from each. The second property’s ratio falls less, because more of its payment was already fixed.
The formula is simple:
New DSCR = old DSCR ÷ (1 + P&I share of payment × % increase in balance).
This holds when the new loan has the same term and the same pricing as the old one. If those change, the answer moves. More on that below.
How Much Does It Drop? A Worked Example
Run the numbers on a rental that covers its full obligation at 1.15x today. These inputs are modeled assumptions, not market facts. Assume principal and interest make up 80% of the obligation. The other 20% is taxes, insurance and dues.
Scenario A: balance up 25%.
- The principal-and-interest slice rises 25%, so the total obligation rises 20% (80% × 25%).
- New ratio: 1.15 ÷ 1.20, or roughly 0.96x.
Scenario B: balance up 15%.
- The total obligation rises 12% (80% × 15%).
- New ratio: 1.15 ÷ 1.12, or roughly 1.03x.
Ten points less cash pulled moved the file from below the 1.00 line to just above it. The ratio isn’t proportional, and small changes in the cash-out amount can matter a great deal near the floor.
Now a file that starts stronger. A property at 1.30x with the same 80% principal-and-interest share and a 25% balance increase lands near 1.08x. It stays above 1.00, but the cushion shrinks.
The Sensitivity Table
This table shows the resulting ratio for different starting ratios and different increases in the total monthly obligation. All figures are illustrative arithmetic.
| Starting DSCR | Obligation +10% | Obligation +20% | Obligation +30% |
|---|---|---|---|
| 1.50x | 1.36x | 1.25x | 1.15x |
| 1.30x | 1.18x | 1.08x | 1.00x |
| 1.15x | 1.05x | 0.96x | 0.88x |
To read it, find your current coverage in the left column. Pick the percentage by which you expect your total payment to rise. The cell is your post-refinance ratio.
Not sure how a balance increase translates into an obligation increase? This second table shows the effect of the fixed pieces.
| Balance increase | Obligation rise (P&I = 80% of payment) | Obligation rise (P&I = 60% of payment) |
|---|---|---|
| 10% | 8% | 6% |
| 25% | 20% | 15% |
| 40% | 32% | 24% |
The heavier your taxes, insurance and dues, the gentler the drop. Same cash-out, different outcome.
How Do You Estimate Your Own Number?
You can do this in four steps.
1. Start with your current coverage, using the rent an appraiser is likely to support, not necessarily your lease.
2. Estimate what share of your payment is principal and interest. Your mortgage statement and tax and insurance bills show it.
3. Decide how much new balance you are considering, as a percentage of the current balance.
4. Multiply the share by the balance increase, add 1, and divide your current ratio by the result.
Then flip it. Reverse math tells you how much cash you can pull before you hit a target.
- Divide your current ratio by your target ratio, then subtract 1. That is the maximum percentage your total obligation can rise.
- Divide that by your principal-and-interest share. That is the maximum balance increase.
Say you start at 1.30x and want to stay at or above 1.00x. The obligation can rise 30%. With an 80% principal-and-interest share, the balance can rise about 37.5%. If you want to land at 1.15x instead, the obligation can rise about 13%, so the balance can rise only about 16%.
Landing exactly at the floor is possible. It is rarely wise. (A file sitting at the minimum has no room for a vacancy, an insurance increase or a reassessment.) Pick the ratio you want to live with, not only the one that clears the line.
The site’s illustrative calculator can help you test these inputs, though it gives estimates, not quotes.
What Changes the Size of the Drop?
Several inputs move the answer. Here is how each one works.
| Factor | Effect on the drop |
|---|---|
| Size of the balance increase | Bigger pull, bigger drop |
| Share of payment that is fixed | More fixed cost, gentler drop |
| Loan terms and pricing | Cheaper new terms soften the drop |
| Payment structure | Interest-only periods reduce the payment |
| Rent the appraiser supports | Higher rent lifts the ratio |
| Taxes and insurance at refinance | Reassessment or a new policy can raise the denominator |
Loan terms and pricing. If the new loan’s terms are cheaper than the old loan’s, the payment may not rise as much as the balance. That is a real exception to the idea that a cash-out always lowers coverage. It’s also why you should never assume a fixed percentage drop. The reverse also holds: pricier terms steepen the fall.
Payment structure. The spine of most programs is the 30-year fixed loan. Select lenders in Lendmire’s wholesale network also offer extended terms such as a 40-year schedule and interest-only periods. ARM structures exist for investors who want them. Longer amortization or interest-only periods lower the required payment, which can lift the ratio. They don’t change the leverage cap.
The rent figure. Your lease and the appraiser’s market rent can differ. The lender orders an appraisal, and a rent schedule comes with it. Appraisers typically use form 1007 for single-family rentals and form 1025 for two-to-four-unit properties. Short-term rentals are underwritten differently, and some programs build the rent figure from hosting history.
Taxes and insurance. These can change at refinance. A reassessment or a new insurance policy moves the denominator independent of the loan increase. Budget for it. Tax and insurance amounts vary by county and property.
Two Tests, One Binding Limit
Your cash-out is capped by whichever test is tighter. That surprises many investors.
Test one is leverage. On a cash-out refinance of a standard rental, the ceiling across most of our wholesale network is 75% LTV. LTV is the loan-to-value ratio: the new loan divided by the appraised value. For short-term-rental collateral the cash-out ceiling is lower, at 70%, while standard rentals stay at 75%. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Test two is coverage. The new payment must clear the program’s DSCR floor. For many select programs, that floor starts at 1.00. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and more leverage. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
The lender sizes the loan to the lower of the two limits. The ratio test often binds first on properties with modest rent relative to value. The LTV test binds first on properties with strong rent. Neither test replaces the other.
Maximum loan size is also not the same as cash in your hand. Cash to you equals the new loan, minus your payoff, minus closing costs and any prepayment charge on the old loan. For a deeper look at the net, see Lendmire’s piece How Much Cash You Walk Away With on a Cash-Out Refinance. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Other gates apply too. Seasoning is the waiting period between buying a property and refinancing it, and about 6 months of ownership is the common expectation. Credit matters: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage. Reserves are cash left over after closing. They commonly run about 6 months of PITIA, stepping up to about 9 months above $1,500,000. On many files, the cash you just pulled out doesn’t count toward them. Everything is subject to lender guidelines and individual underwriting.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
Max Pull, Moderate Pull or Payoff Only?
You don’t have to take the maximum. Compare three approaches.
| Approach | Effect on ratio | Cushion | Typical use |
|---|---|---|---|
| Maximum pull | Largest drop | Thin | Funding a purchase |
| Moderate pull | Smaller drop | Moderate | Repairs, reserves |
| Payoff only | Little or no drop | Preserved | Lock in better terms |
A payoff-only refinance, with no cash back, leaves the balance roughly where it was. Changes to the payment come from the new terms rather than from added debt.
A moderate pull is often the strongest play. Take enough cash to fund the next deal’s down payment or a needed renovation. Leave enough cushion to survive a vacancy. This one’s a genuine judgment call. A maximum pull can make sense for an investor with deep reserves and strong rents. It looks much riskier on a file that clears the floor by a hair.
What If the New Ratio Falls Short?
You have options. Here they are, roughly from simplest to most involved.
1. Take less cash. As the sensitivity table shows, small reductions can restore coverage.
2. Document higher supportable rent. If the lease or market rent is higher than the appraiser’s first read, the file may support a stronger ratio. The lender decides what rent counts.
3. Change the structure. An extended amortization or an interest-only period, available through select lenders in the network, lowers the payment the ratio is tested against.
4. Choose a below-1.00 program. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. Scotsman Guide notes that some non-QM lenders will go below 1.0 when the borrower has other assets to cover the shortfall.
5. Refinance without cash first. A payoff-only refinance can reset terms, and a later cash-out is possible once the file is stronger.
Each fix trades something. Less cash means less to deploy. A below-1.00 program means lower leverage and adjusted terms. Pick based on what the cash is for.
Does Passing the Ratio Mean the Property Makes Money?
No. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities and capital expenses sit outside the calculation.
A property at 1.05x can lose money in a year with a long vacancy and a roof replacement. A property at 1.40x has more room, but it is still not guaranteed to cash-flow. Scotsman Guide treats 1.0 as the breakeven point on the payment. That is breakeven on the mortgage, not on the business.
Related misconception: that DSCR loans qualify the property and ignore the borrower. The property’s income is the center of the file, but the borrower’s credit, reserves and experience still matter. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
Is a Cash-Out Worth the Lower Ratio?
Compare two numbers. First, the added carrying cost: how much the new payment rises, and how much of your cushion disappears. Second, the return you expect on the redeployed cash.
If the cash funds a down payment on a property that produces strong coverage of its own, the trade may work. If it sits in an account or goes toward a purchase with thin coverage, you have raised your risk on one property to fund another. Costs also reduce your proceeds: closing costs, and any prepayment charge on the loan you pay off.
Another angle is to consider your other options. Selling takes the equity without adding debt but gives up the asset. A cash-out keeps the property and the income stream. For a related look at how lenders weigh debt across a portfolio, see Lendmire’s guide on using a cash-out refinance to lower your debt-to-income ratio.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
On the files a broker sees across a wholesale network, the coverage ratio is rarely the surprise. The surprise is usually the insurance quote or the appraiser’s rent figure arriving lower than the investor assumed. Running the ratio with a conservative rent and a fresh insurance number before applying prevents most of those.
Key Terms Defined
DSCR (debt service coverage ratio): The property’s qualifying monthly rent divided by its full monthly obligation.
PITIA: Principal, interest, taxes, insurance and association dues, the full monthly cost of owning the property.
LTV (loan-to-value): The loan balance divided by the property’s appraised value.
Cash-out refinance: A new, larger loan that pays off the old one and returns the difference to you.
Seasoning: The waiting period between buying a property and refinancing it.
Amortization: The schedule over which a loan’s principal is paid down.
Interest-only period: A stretch in which the payment covers interest alone, lowering the monthly obligation.
Frequently Asked Questions
Does a cash-out refinance always lower my DSCR?
Almost always, because the larger balance raises the payment while rent stays flat. The exception is a new loan with cheaper terms or a longer schedule, which can offset the added balance. Run your own numbers before assuming either direction.
Is DSCR recalculated on the old payment or the new one?
The new one. The lender tests the rent against the full payment on the new loan amount. Your existing payment doesn’t count once the old loan is paid off.
Do I need 1.25x to do a cash-out refinance?
Not necessarily. The 1.25x benchmark comes from commercial lending. Residential programs set their own floors, and many select programs start at 1.00. Stronger ratios generally earn better pricing and leverage.
Does the rent on my lease or the appraiser’s rent count?
The lender uses the rent supported by the appraisal’s rent schedule.
Can a bigger down payment on my next purchase fix a low ratio?
A larger down payment lowers the loan and the payment, which can lift coverage on that purchase. It never erases leverage caps, credit floors, reserve rules or property eligibility. Manufactured homes, log homes and barndominiums are not offered in these programs at all. The strongest files have enough equity and enough rental coverage.
