How a Lender Sizes a Cash-Out Refinance on a Locked-in Rental

How a Lender Sizes a Cash-Out Refinance on a Locked-in Rental

The Quick Read: A lender runs two tests on your rental and lends the smaller result. One test is appraised value times the cash-out LTV cap. The other is the largest loan whose new payment your rent can cover. Payoff, closing costs, and reserves then come out of that loan to leave your cash.

  • Across most programs in Lendmire’s wholesale network, cash-out tops out at 75% LTV (loan-to-value, the loan as a share of appraised value) on a standard rental.
  • Rent is tested against the new, larger payment, not your old one.
  • A cash-out replaces your whole low-rate balance, not just the new cash.
  • About 6 months of ownership is the common seasoning expectation.
  • Clearing 1.00 coverage is a program floor, not proof the property cash-flows.

Key Terms Defined

Cash-out refinance: a new, larger loan that pays off the old mortgage and hands you the difference in cash.

LTV (loan-to-value): the loan amount divided by the property’s appraised value.

DSCR (debt service coverage ratio): monthly rent divided by PITIA, the full monthly housing obligation.

PITIA: principal, interest, taxes, insurance, and association dues, all in one monthly figure.

Seasoning: the waiting period after you take title before a lender will size off appraised value instead of what you paid.

Locked-in: holding a first mortgage far cheaper than today’s market and not wanting to give it up.

What Does “Locked-in” Mean for a Rental Owner?

You own a rental with a mortgage that is cheaper than anything on offer now. Selling or refinancing feels like a loss, so you sit still. You are not alone. Realtor.com data reported by HousingWire shows 65.6% of outstanding mortgages sit below 5%, and about 42.8% were originated in the pandemic-era window.

Here is the catch for investors. A DSCR cash-out is a full replacement. The old low-rate loan gets paid off. Everything you borrow, old balance included, reprices together. That is the central trade-off, and it shapes how the sizing works out in practice.

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.

How Does Underwriting Size the Loan, Step by Step?

The sequence is the same on most files we place. The details move by program, and every file is underwritten individually.

1. Classify the file. The lender confirms the property is non-owner-occupied and the loan is for business purposes.

2. Order the appraisal. The lender orders it, not you. It returns a value and a market rent. Market rent comes from a rent schedule: Form 1007 for a single-family rental, Form 1025 for a small residential income property.

3. Pick the value basis. Inside the seasoning window, lenders commonly size on the lower of appraised value or cost basis (purchase price plus documented improvements). After it, they size on appraised value. About 6 months of ownership from title recording is the common expectation across the network.

4. Compute the value cap. Appraised value times the cash-out LTV cap. On a standard rental, that cap is 75%.

5. Compute the rent cap. The lender works backward. It takes the rent, divides by the coverage the program requires, and gets the largest monthly payment the rent supports. Then it converts that payment into a loan balance.

6. Take the lesser of the two. That is your maximum loan.

7. Subtract the costs. Payoff of the old loan, closing costs, any prepayment penalty on the old loan, and required reserves come out. What is left is your check.

Rent comes from the lease if the unit is occupied. If it is vacant, the appraisal’s market rent is used.

Why Is the Rent Test Often the One That Binds?

Most investors assume equity sets the loan. Often rent does.

Coverage is tested on the new payment. As the loan grows, the payment grows, and the ratio shrinks. At some balance, the rent can no longer cover the payment at the program’s floor. That balance is your rent cap, and it can sit below your value cap.

Think of a rental bought years ago and now worth a lot more. Equity looks huge on paper. But the rent did not rise as fast as the value, so the rent supports a smaller loan than 75% of value would allow. The lender lends the smaller number.

Select programs start at 1.00 coverage, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Those are different paths, not one program with a moving floor.

A Worked Example With Both Tests

Run the numbers on a long-term rental with an appraised value of $400,000. These figures are modeled assumptions, not market data.

Test What sets it Result
Value cap Appraised value × 75% cash-out LTV $300,000
Rent cap Largest loan whose payment the rent covers at the program floor Say, about 70% of value
Maximum loan The lesser of the two The rent cap binds

In that case, the rent test wins even though the value test would allow more. You would net less cash than the equity suggests.

Now the draw-size picture. The more cash you request, the thinner coverage gets:

Cash requested Coverage on new payment Reading
Modest Comfortably above 1.2x Cushion preserved
Mid-range Around 1.1x Passes, thinner cushion
Maximum Near the floor Passes barely, if at all

The lesson: borrow the cash you need, not the ceiling.

What Comes Out of the Check?

Gross loan is not your cash. Here is the waterfall.

Deduction Who sets it
Old mortgage payoff Your current servicer’s payoff statement
Closing costs Lender and title provider
Prepayment penalty Terms of the old or new loan
Required reserves Program, by leverage and loan size

Reserves typically run around 6 months of PITIA on most files, stepping up to about 9 months on loans above $1,500,000. Reserve rules vary by lender, leverage, and transaction type.

Check your break-even appraisal too. Divide payoff plus exit costs by the LTV cap. A small appraisal miss can flip a cash-out into a cash-to-close file. Both value and market rent come from the same appraisal, so a low number hits you twice.

How Does the Old Low Rate Change the Decision?

Compare costs on the whole balance, not the new cash alone. If you owe a large balance at a cheap rate and pull modest cash, the new loan reprices the entire balance. The cash has to be worth that blended cost.

Run a quick test before you apply:

  • What is the old payment, and what would the new one be at the loan you want?
  • Does coverage still clear the program floor with room to spare?
  • Does the cash earn more than the extra cost on the full balance?

If the answer to the last question is no, keeping the first loan may be smarter. Another route is a smaller cash-out sized to your actual need. The worth of the cash depends on what you buy with it. Proceeds that fund the next rental purchase can make sense, but each new property then needs its own coverage and its own seasoning clock.

Where Does the General Rule Break?

Short-term rentals. Cash-out is capped lower, at 70% LTV on short-term-rental collateral. Expect a 640+ score and about 12 months of hosting history. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

Delayed financing. A true cash buyer can often recover roughly the price paid before seasoning ends. Extra appraised equity stays put until the clock runs out. The exception generally breaks if a lien existed at purchase, as with hard money.

Payoff-only refinances. If the new loan only retires a bridge or hard-money loan, it may be classified as rate-and-term, which carries a higher ceiling of 85% LTV on this network’s programs. If any cash comes back, cash-out seasoning and the 75% cap apply.

Rehab and after-repair value. Lenders generally size on the appraisal they order, not your projected after-repair value. An improvement may support a higher appraised value, depending on comps and underwriter review.

Business purpose. DSCR loans are business-purpose loans. The federal rule on business-purpose credit looks at what the credit is for, not only the property type. The CFPB’s commentary also notes that exempt business credit can later be refinanced for consumer purposes. Personal spending weakens the story; buying more rentals supports it.

Ineligible property types. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered through these DSCR programs.

What Do Lenders Look For Beyond the Math?

Credit matters. A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. Standard loan sizes run up to $3,000,000, and above $2,500,000 the network generally holds to 30-year fixed structures. Extended terms and interest-only periods are available through select lenders.

Here is the practitioner view. On cash-out files, the surprise is almost never the LTV cap. It is the rent figure. A lease signed below market, or an appraisal rent schedule lower than expected, shrinks the rent cap before equity ever enters the picture. Investors who check market rent before ordering the appraisal avoid most of those surprises.

Documents typically in play: the appraisal with rent schedule, the lease if occupied, the current payoff statement, entity documents if the property sits in an LLC (subject to lender program eligibility), a business-purpose certification, and the insurance and tax figures that feed PITIA.

Does Passing Coverage Mean the Property Cash-Flows?

No. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex all sit outside the calculation. A property can clear 1.00 and still lose money after a bad month.

A larger payment thins your cushion on top of that. Pull what you need, keep room, and treat the coverage ratio as a program test rather than a profit forecast.

Frequently Asked Questions

How much cash can I pull out of a rental?

It depends on the lesser of two caps: 75% of appraised value on a standard rental, or the loan your rent can carry at the program’s coverage floor. Then payoff, closing costs, any prepayment penalty, and reserves come out. Subject to lender guidelines, no figure is guaranteed until the appraisal is back.

What if the rent is too low for the loan I want?

The rent cap wins and the loan shrinks. Options include requesting less cash, waiting for a lease reset, or asking about a select-lender path below 1.00 coverage with leverage and terms adjusted.

Does the lender look at my personal income?

A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Credit and reserves still matter, so expect those to be reviewed.

How long must I own the property first?

About 6 months, measured from title recording, is the common expectation. Before that, lenders commonly size on the lower of appraised value or cost basis. Policy varies by lender.

Do I lose my old low rate?

Yes. A cash-out replaces the entire first mortgage, so the low-rate balance is paid off and reprices with the new cash. Weigh the blended cost on the whole loan against what the cash will earn. Tax treatment varies; consult a qualified professional.
