The Quick Read: A lender sizes this loan by running two tests and taking the lower answer: a value test, which applies the leverage cap (around 75% on a standard rental cash-out) to the property’s value, and a rent test, which asks whether rent used for lender review covers the full new payment at the program’s minimum coverage. The low first mortgage does not sit underneath the new loan. It gets paid off and replaced, so the entire balance reprices, subject to lender guidelines.
- The maximum loan is the lower of the value-side limit and the rent-side limit.
- Your cash is the new loan minus the first-mortgage payoff, any junior liens, closing costs, and any prepayment charge on the old note.
- A low balance widens the equity gap, but it also raises the payment more than you might expect, because the whole balance is replaced.
- On a low first mortgage, the rent test binds more often than the value test.
- Clearing the coverage minimum is not the same as positive cash flow.
What Does “Sizing” a Cash-Out Loan Actually Mean?
Sizing is the process of finding the largest new loan a file supports, then subtracting what must be paid off to see what you actually receive. Lenders do not start with the cash you want. They start with value, rent, and the existing debt.

A cash-out refinance, in the plainest terms, is a new, larger loan that pays off the old mortgage and hands you the difference. Corporate Finance Institute describes it the same way. The new loan replaces the old one. It is not stacked on top of it.
That one fact drives everything below. If you own a rental with a small, cheap first mortgage, you are not borrowing against the equity while keeping the old loan. You are swapping the old loan for a new one, and the lender sizes the new one from scratch.
Across the wholesale network of DSCR lenders that Lendmire works with, cash-out on a standard rental tops out around 75% of value. About 6 months of ownership, measured from the date title was recorded, is the common seasoning expectation. The rest of this article shows how those numbers meet rent coverage. For the broader program picture, the complete DSCR loans guide covers the basics.
Key Terms Defined
LTV (loan-to-value): The new loan divided by the property’s value, shown as a percentage.
DSCR (debt service coverage ratio): On a one-to-four-unit rental loan, monthly rent used for lender review divided by the full monthly payment.
PITIA: Principal, interest, taxes, insurance, and association dues, which together make up the full monthly payment.
Seasoning: The waiting period a lender wants after you buy before it will size a loan on a higher value.
Payoff: The balance owed on the loans the new loan replaces, including the first mortgage and any junior lien.
Rent used for lender review: The rent figure the lender uses in the coverage test. Many programs use the lower of the signed lease or the appraiser’s market rent.
Value basis: The value the leverage cap is applied to. It is either cost-based or appraisal-based, depending on seasoning.
What Are the Two Limits Behind Every Cash-Out Loan?
Every cash-out file has a value-side limit and a rent-side limit. The lender approves no more than the lower one. Many borrowers focus on the first and discover the second late.
| Limit | What it measures | Formula | What shrinks it |
|---|---|---|---|
| Value side | Equity cushion | Leverage cap × value basis | Low appraisal, short ownership |
| Rent side | Payment affordability | Largest loan whose full PITIA fits the rent at minimum coverage | Thin rent, high taxes or insurance |
The value-side limit is simple. If the cap is 75% and the value basis is the appraisal, the loan cannot exceed 75% of that appraisal.
The rent-side limit takes more work. The lender takes rent used for program review and asks how large a loan it can carry. The payment must stay low enough that rent divided by PITIA reaches the program’s minimum. For many select programs that minimum is 1.00. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger coverage opens better pricing and higher leverage.
Taxes, insurance, and dues do not shrink when the loan shrinks. Only the principal-and-interest slice does. So each extra slice of loan raises the payment, and the coverage ratio falls faster than most people expect.
One caution on terminology: commercial and large multifamily lenders define coverage as net operating income divided by debt service, as Stessa explains. Loans on one-to-four-unit rentals typically compare rent to the full PITIA instead. If a calculator or article uses the commercial formula, its answer will not match a rental DSCR file.
Why Does a Low First Mortgage Change the Math?
A low first mortgage makes the equity gap large, so the value test usually leaves room. The catch is that the new loan replaces the old balance entirely. Every dollar of the old loan reprices on the new terms, not just the cash you take out.
Think about what the old loan did for you. A small balance meant a small payment, which meant very strong coverage on paper. That coverage belonged to the old loan. It does not carry over.
When the balance jumps from, say, a quarter of value to three quarters of value, the principal-and-interest portion of the payment roughly triples on similar terms. Taxes and insurance stay put. So a property that showed 2x coverage on the old loan can land near 1.1x on the new one. Same rent. Same building. Very different ratio.
That is why, for owners with a low first mortgage, the rent test is the one that most often binds. You have plenty of equity. The question is whether the rent can carry what you ask the equity to become.
Worked Example: Two Properties, Two Different Limits
These are modeled assumptions, not market data. All figures are percentages of value and coverage ratios, so you can see the logic without payment dollars.
Both properties are standard rentals, each with a first mortgage equal to 25% of appraised value. Both are past seasoning, so the lender uses the appraisal. Both programs use a 75% cash-out cap and a 1.00 coverage minimum. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
1. Value basis: the appraisal, treated as 100%. 2. Value-side limit: 75% of value. 3. Rent test at that 75% loan: coverage comes out near 0.92x, which is below the 1.00 minimum. 4. To reach 1.00, the lender must shrink the principal-and-interest slice by roughly a tenth, since taxes and insurance do not move. That puts the rent-side limit in the high 60s as a percent of value. 5. Maximum loan: the lower number, so roughly 67% of value. 6. Gross cash before costs: about 67% minus the 25% payoff, or roughly 42% of value.
Under this model, the value test would have allowed about 50% of value in gross cash. Rent trimmed it by eight points.
1. Value basis: the appraisal, treated as 100%. 2. Value-side limit: 75% of value. 3. Rent test at that 75% loan: coverage comes out near 1.25x, comfortably above the minimum. 4. Rent-side limit: higher than the value limit. 5. Maximum loan: 75% of value. 6. Gross cash before costs: about 50% of value.
Same equity, same cap, different rent. Property B gets the full cash-out and Property A does not.
Now add a third wrinkle. Suppose Property B’s appraisal comes in light. The value basis drops, the 75% cap applies to a smaller number, and the loan shrinks with it. The normal response is to ask for reconsideration with fresh comparable sales. The lender decides whether the new comps are usable.
What Rent Figure Does the Lender Use?
Lenders typically want rent evidence from the appraisal, a signed lease, or both. Many programs review the file on the lower of the lease and the appraiser’s market rent. That is a common approach, not a universal rule, so check the program.
For a single-family rental, the appraiser typically completes a comparable rent schedule, known as Form 1007. For two-to-four-unit properties, the report is Form 1025. Fannie Mae’s appraiser guidance explains how the 1007 market rent schedule is used and why it does not fit short-term rentals. Those forms are used here for naming only. DSCR files are not governed by agency selling guides.
If your lease sits well below market, the lower figure usually controls. A rent bump before you apply may help the rent test, but only if the lender accepts the new lease. Do not count on it.
What Comes Out of the Check, and in What Order?
Your cash is the new loan minus a short stack of deductions. Lenders pay these off at closing before anything reaches you, so the figure is always smaller than the cap implies.
1. First-mortgage payoff. The full balance, plus accrued interest.
2. Junior liens. Any second loan or line against the property must be paid off or, in rare cases, subordinated. Check what the lender allows.
3. Closing costs. Appraisal, title, lender and broker fees, and escrow setup.
4. Prepayment charge on the old note. If your existing loan is a DSCR loan or other investor loan, it may carry one. This line surprises people.
5. Any holdbacks. A lender may hold funds for repairs it requires.
Reserves are a separate item. Reserves are cash you must show after closing, commonly around 6 months of PITIA across most programs, stepping up to about 9 months on loans above $1,500,000. Some programs let the cash-out proceeds count toward reserves, and that varies by lender. Reserves are shown, not deducted from your check.
Then there is the question of what happens if the refinance returns little or no cash. A refinance that pays off the old loan and returns minimal cash can be treated as a rate-and-term transaction, while any meaningful cash back puts the file on the cash-out line with its lower leverage cap. Fannie Mae’s guide draws a similar line for its own loans. DSCR lenders set their own thresholds, so confirm the cutoff on the specific program.
Where Does the General Rule Break?
The two-limit rule holds in most files. These edge cases are where it bends.
Inside the seasoning window. If you bought recently, many programs size the loan on the lower of cost or appraisal, with cost including documented improvements. A plan to cash out on after-repair value before seasoning clears is a common stall. Waiting out the roughly 6-month window can change the value basis, and that changes the proceeds.
A recent cash purchase. Some programs offer delayed-financing style sizing near documented cost for a property bought with cash. Availability varies by lender, so ask early.
A free-and-clear rental. No first mortgage does not mean no cash-out. A loan on a property with no existing debt that returns cash is still a cash-out refinance. It simply has nothing to pay off.
Short-term rentals. Cash-out on short-term rental collateral generally tops out around 70%, while standard rentals reach 75%. Expect a 640+ credit score, about 12 months of hosting history, and a 1.00 coverage floor on refinances. Lenders look harder at income that swings with the season. Some use a market-data report instead of a Form 1007. 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.
Interest-only structures. Some select lenders in the network offer interest-only periods. Certain programs measure coverage against the interest-only payment during that period. That can lift the ratio and enlarge the rent-side limit. Confirm on the program sheet, because the coverage test may reset when principal payments begin.
Longer terms and adjustable options. The 30-year fixed is the spine of the network. Select lenders also offer 40-year terms, which lower the payment and can help coverage. Adjustable structures exist for investors who want them. Above $2,500,000, the network generally holds to 30-year fixed.
Low credit scores. A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. A lower score can pull the leverage cap down and tighten the rent test.
Entity title. Many DSCR programs allow the property to be held in an LLC, subject to lender program eligibility. Confirm entity requirements before you retitle anything.
Property types that are not offered. Manufactured homes (single- and double-wide), log homes, and barndominiums fall outside these programs. Equity in those property types cannot be sized here.
Small balances. If the new loan would land below the standard-program minimum, the file routes through select lenders in the network. The loan guide runs up to $3,000,000 on standard programs.
Sub-1.00 Coverage: A Different Path, Not a Lower Floor
Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. It is a different program, not the same program with a softer cutoff.
In practice, expect a lower leverage cap and tighter terms. In the Property A example above, a sub-1.00 path could change the rent-side limit. It would not restore the full 75% cap. Each file is reviewed individually, subject to credit approval and property review.
Should You Keep the Cheap Loan or Replace It?
Replace it only if the cash is worth more to you than the cheap financing you give up. That is the whole decision, and it can be reduced to one comparison.
On one side, the cost of replacing: your old balance now carries the new loan’s terms, you pay closing costs, and any prepayment charge on the old note comes out of proceeds. On the other side, the value of the cash: what you will earn, save, or build with it.
A few ways to frame it:
- The cash buys a better asset. If the next property’s return clearly beats the added cost of repricing the old balance, replacing can make sense. If it only matches it, it probably does not.
- The new payment strains the rent. If coverage lands just above the minimum, a vacancy or a repair can leave you paying out of pocket. Coverage is a lender test. It is not a cash-flow forecast, since repairs, vacancy, management, utilities, and capital expenses sit outside it.
- You only need a little cash. A smaller cash-out reprices the same balance but leaves more coverage cushion. Sometimes a modest draw is the right size.
- You want to keep the first loan. Leave it alone and raise the money another way, such as bringing in an equity partner. Lendmire’s piece Rental Cash-Out Refinance vs. Equity Share Over a Low First Mortgage walks through that tradeoff.
A larger down payment, or in this case a lower loan amount, lowers the payment and can lift coverage. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
What Should You Prepare Before You Apply?
Gather the items that feed the underwriting limits. Most files stall on missing paperwork, not on the math.
- Payoff details: a current statement for the first mortgage and any junior lien, plus the terms of any prepayment charge.
- Rent evidence: the signed lease and proof of the security deposit, plus any rent history you can show.
- Expense records: current taxes, insurance, and association dues, since they sit inside the payment.
- Reserve proof: statements showing the cash you will hold after closing.
- Ownership records: the recording date for title, so seasoning can be measured, and entity documents if the property is in an LLC.
A mortgage broker like Lendmire shops multiple wholesale lenders and matches your leverage, coverage, credit, and property type to the program that fits. The best program for your situation depends on where the rent test lands, not on the headline cap.
Frequently Asked Questions
Does a low first mortgage raise my cash-out?
It raises your equity, which loosens the value-side limit, but it does not raise the loan. The new loan is capped by value and by rent coverage, and the old balance simply gets paid off from it. A low balance means less comes out of the check at payoff. It also means the repriced balance is a bigger jump in payment.
Can rent limit the loan below the value cap?
Yes, and on a low first mortgage it often does. The lender finds the largest loan whose full PITIA your rent used for eligibility review supports at the program’s minimum coverage. If that figure is below the value cap, the rent figure wins. Taxes, insurance, and dues stay fixed as the loan shrinks, so thin rent can cut the loan more than you would guess.
Are junior liens paid off at closing?
Typically yes. A second loan or line against the property generally has to be paid off from the proceeds or, in limited cases, subordinated, depending on the program. Whether a payoff of that lien changes the transaction type depends on how much cash comes back to you. Confirm the threshold with the lender.
Why is my actual cash smaller than the cap suggests?
The cap is the maximum loan, not your check. Payoff, junior liens, closing costs, and any prepayment charge on the old note all come out first. Reserves are shown separately and are not deducted, though some programs let proceeds count toward them.
Does clearing the coverage minimum mean the rental makes money?
No. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital spending are outside the calculation. A property can clear the minimum and still cost you money in a slow month.
