The Quick Read: It depends on how much equity the rental holds, because the line is the property value times the maximum combined loan-to-value, minus every lien already on it, and then the program’s dollar limits trim the result, while rent coverage only decides whether you qualify, not how much you can borrow. Combined loan-to-value (CLTV) adds your first mortgage balance and the full new line, then divides by value. Everything below applies to non-owner-occupied rentals, through select programs in Lendmire’s wholesale network and subject to underwriting.
- Second lien behind your first mortgage: up to 70% CLTV at a 720 credit score or better, on lines from $50,000 to $500,000.
- First lien on a rental with no mortgage: up to 75% loan-to-value (LTV) at 740 or better, on lines to $500,000.
- Rent coverage: monthly rent must cover a stress payment on the whole line at 1.10x or better.
- Odd man out: a rental bought or refinanced in the last 6 months is not eligible. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
How Do You Size the Line, Step by Step?
Start with value, apply the leverage cap for your lien position, subtract what is already recorded against the property, and compare the result with the program’s line limits. Then check the rent test. The smaller of the equity answer and the rent answer is your ceiling.
Here is the sequence in plain terms:
1. Value. The lender orders a valuation (more on that below). Its number, not your purchase price, drives everything.
2. Cap. Multiply value by the maximum CLTV or LTV for your credit tier and lien position.
3. Subtract liens. Take out the first mortgage balance and any other recorded lien.
4. Apply line limits. Lines start at $50,000. A second lien tops out at $500,000, and a first lien can reach $1,000,000.
5. Run the rent test. If the rental fails coverage at that size, the line has to shrink or the file does not work.
One detail trips up many owners. The leverage test counts the full credit limit, not just what you plan to draw. A line you intend to use lightly still uses up the full amount of equity room.
Does Rent Raise the Amount You Can Borrow?
No. Rent coverage works as a gate, not a dial. Strong rent gets you through the door, but equity and the leverage cap set the size.
The test itself is simple. Gross monthly rent divided by the qualifying payment must reach 1.10x. The qualifying payment is a fully amortizing payment on the entire credit limit, calculated at a stressed level set by the lender. That is deliberately harsher than what you would owe on a partial draw. Taxes and insurance are not part of the qualifying payment.
Rent counts as the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A lease in place is required. A two-to-four-unit building can have at most one vacant unit. If you are wondering about an empty unit, Lendmire’s piece How Much Can You Borrow on a DSCR HELOC on a Vacant Rental Without a Lease? covers where that path stops.
Here is where rent can quietly cap your line. The stress payment grows with the limit, so coverage shrinks as the line grows. A rental that clears 1.10x at a modest line may fall short at the maximum your equity would allow. In that case, rent is the binding limit, and a smaller line is the answer.
The program is qualified on the rental’s income, not yours: no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines. The rent, the lease, your credit report and the valuation are all documented.
What Do Lien Position and Credit Score Change?
They set your leverage cap and your maximum line. A second lien behind a mortgage you keep needs 720 or better. A first lien on a rental with no mortgage opens at 700 and rises with the score. These are ceilings through select programs, not offers.
| Position | Credit score | Max leverage | Line size |
|---|---|---|---|
| Second lien | 720 or better | 70% CLTV | $50,000–$500,000 |
| Second lien | Below 720 | Not offered | Not applicable |
| First lien, no mortgage | 740 or better | 75% LTV | To $500,000 |
| First lien, no mortgage | 700 to 739 | 70% LTV | To $500,000 |
| First lien, line over $500,000 | 720 or better | 65% LTV | To $1,000,000 |
Read the table carefully. Anyone who keeps a first mortgage can only take a second lien, and that route has a 720 floor. A first lien exists only on a rental with no mortgage. The bigger first-lien lines carry a lower ceiling, so a borrower at 740 who wants more than $500,000 plans around 65% LTV, not 75%. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
The credit tier uses the lender’s own report. Beyond the score, a 30-day mortgage late in the last 12 months is a problem. So is a bankruptcy, foreclosure, short sale or deed-in-lieu inside the last 48 months. No reserves and no cash to close are required.
How Does the Math Look on Real Rentals?
Run the numbers in percentages of value, because that is how the cap works. Four common situations show the range.
A mortgaged rental with real equity. Say your first mortgage sits at 50% of value and you qualify for a second lien at 720 or better. The 70% CLTV cap leaves about 20 points of value. That room has to be worth at least the $50,000 minimum line, so the property’s value matters as much as the percentage.
A recently bought rental. An investor who purchased at high leverage, say a first mortgage at 65% of value, has only about 5 points of room under the 70% CLTV cap on a second lien. For most properties that is below the minimum line. Paydown or appreciation has to build the room first, and the seasoning rule applies on top.
A rental at or above the cap. If the first mortgage already sits at 70% of value or more, a second lien has no room at all.
A paid-off rental. With no mortgage, the owner can take a first lien. At 740 or better, the cap is 75% LTV on lines to $500,000. At 700 to 739, it is 70% LTV. A line above $500,000 runs under the 65% LTV ceiling at 720 or better, up to $1,000,000. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Two adjustments can shrink any of these. A declining-market flag from the valuation can lower the ceiling by 5 points, subject to underwriting. Philadelphia lines carry a ceiling 10 points lower.
Keep in mind that 30% of value stays untouched at a 70% CLTV. Borrowing against 100% of your equity is not on the menu.
Which Rentals and Borrowers Qualify?
Eligible properties include single-family homes, PUDs, townhomes, two-to-four-unit buildings, and warrantable and non-warrantable condominiums. Lots up to 10 acres also qualify. The leverage tiers above govern every property type.
Several property types are outside this program. Those include rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds and land trusts. Age-restricted communities, hobby farms, modular and log homes, land contracts and mixed-use buildings are out too. So is a property listed for sale in the prior 2 months and one carrying a solar lien. 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.
Borrowers can be U.S. citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
An LLC can hold title, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. A personal-income investment HELOC is a different product with different title rules, so do not mix the two when you compare options.
Why Does Seasoning Decide When You Can Borrow?
A rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date).
This matters because the line is never closed together with a purchase. You borrow against a rental you already own. Many investors use the proceeds as a down payment on the next property, with a separate purchase loan covering the rest.
How Does the Valuation Work?
The valuation sets the number everything else multiplies. For lines up to $400,000, the file uses an automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal on Form 1004, 1073 or 1025. Appraisal waivers are not accepted.
The appraisal’s rent schedule also feeds the coverage test. NerdWallet notes that multiple appraisals may be required on an investment-property HELOC, so a second look at value is a normal part of this product category.
Title work follows the line. A full title policy applies on a first lien and on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report. Hazard insurance must cover both liens, with flood coverage where required.
How Do Draws and Repayment Work?
You draw most of the line on day one. At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. On the smallest lines, that means the whole line is drawn at closing. Later draws must be at least $5,000 each.
The draw period runs 5 years, interest-only on the drawn balance. Then a 25-year fully amortizing repayment period begins, with a 30-year maturity. The rate is variable.
That variable rate and the large closing draw are the real risks. You are borrowing against a tenant-dependent asset, and your payment can move. Size the line to what the property can carry through a vacancy, not to the maximum the formula allows.
Exposure has a ceiling too. One borrower can have at most 5 loans or $2,500,000 with the program. Each line is secured by one property, so equity in one rental cannot support a line on another.
HELOC, Cash-Out Refinance or Bank Line: Which Fits?
A DSCR HELOC leaves your first mortgage alone, while a cash-out refinance replaces it. If your existing first mortgage is one you want to keep, a second-lien line is the natural fit. If you need more than the $500,000 second-lien limit, or your credit is below 720 with a mortgage in place, a DSCR cash-out refinance is the usual alternative.
Another advantage is where the risk sits. The lien is on the rental, not on your home. For many landlords, that separation is the point.
Bank lines work differently. NerdWallet says you may have fewer lenders to choose from on an investment property and may not be able to borrow as much as against a primary home. Investors on BiggerPockets describe having to call around to find a bank that offers a rental HELOC at all, though that thread is about eight years old. Big banks and other depository lenders often underwrite these lines on personal income, which is a different test than rent coverage.
Across a wholesale network, programs vary on lien position, credit floors and title rules. That is why the details above matter more than any one headline percentage. For the full picture of how rent-qualified lending fits together, see Lendmire’s complete DSCR loans guide.
Key Terms Defined
DSCR: the debt-service coverage ratio, meaning gross monthly rent divided by the qualifying payment. On this program the minimum is 1.10x.
Stress payment: the lender-set qualifying payment on the entire credit limit, deliberately higher than a payment on the drawn balance.
Second lien: a loan recorded behind your first mortgage, which stays in place.
First lien: a loan in first position on a rental with no mortgage.
Draw period: the 5 years during which you borrow from the line and pay interest only on the drawn balance.
Seasoning: the waiting period between a purchase or refinance and a new line.
Frequently Asked Questions
Does strong rent let me borrow more?
No. Rent coverage is a pass-or-fail test at 1.10x or better, and it never raises the amount. Equity and the leverage cap set the size. Rent can lower your ceiling, though, because the stress payment is tested on the whole line, so a bigger line means thinner coverage.
Can my LLC hold title on the line?
Yes, subject to program terms. The LLC can stay on title, and its members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line also do not need to be the borrowers on the first mortgage.
How long do I have to own the rental first?
Two six-month clocks apply: the line is not available on a rental bought or refinanced in the last 6 months (last note date to new note date), and title must have been held for 6 months (settlement date to note date). Both clocks have to be satisfied before the file is eligible.
Can I draw only a small part of the line?
Not at closing. At least 80% of the line is drawn then, and the closing draw is never less than $50,000. After that, each draw must be at least $5,000. Because the leverage test counts the full limit, a smaller line is the way to borrow less.
Can I use equity in one rental for a line on another?
No. Each line is secured by the one property it sits on, and the equity room is measured on that property alone. Across several rentals, one borrower can have at most 5 loans or $2,500,000 with the program, and the program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
