The Quick Read: It depends on three ceilings, and the lowest one sets your line: the equity limit (value times the program’s combined leverage ceiling, minus what you already owe), the rent limit (the rental must cover a stress payment on the whole line at 1.10x), and the program’s dollar maximum.
- Second lien: a line behind the first mortgage you keep reaches up to 70% combined loan-to-value at a 720 credit score or better, on lines from $50,000 to $500,000, subject to underwriting.
- First lien: a rental with no mortgage reaches 75% loan-to-value at 740 or better and 70% from 700 to 739 on lines to $500,000. Lines above $500,000, up to $1,000,000, are held to 65% at 720 or better.
- Rent test: the rent is measured against a payment on the entire credit limit, not just the dollars you draw.
- Draw rules: at least 80% of the line is drawn at closing, so size the line for money you will actually use. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
These are ceilings through select programs, not offers. Every file is underwritten individually.
What Is a DSCR HELOC, Exactly?
A DSCR HELOC is a revolving line of credit secured by a rental you keep. It is written as a standalone second lien behind your existing first mortgage, or as a standalone first lien on a rental with no mortgage. It is never a third lien, and it is never a line on your own home.
The rent qualifies the line. Lenders in this lane do not ask for tax returns, W-2s or pay stubs, and they do not calculate your personal income. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
The first mortgage stays exactly as it is. That is the appeal for an owner who is happy with the first loan and wants to reach the equity without replacing it.
Your LLC can stay on title, subject to program terms. The LLC’s members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment.
A line that is reviewed on rent is a narrower product than one reviewed on personal income and debt load, and that is why the details below matter. NerdWallet notes that investment-property lines come from a smaller pool of lenders, carry strict requirements, and generally allow less borrowing than a line on a primary home.
Key Terms Defined
DSCR (debt service coverage ratio): the rental’s income divided by its debt payment. A result above 1.00 means the income covers the payment, as this general explanation of the formula puts it. On this program the top number is gross monthly rent.
LTV (loan-to-value): the loan balance divided by the property’s value. You use it for a first lien.
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by value. You use it for a second lien.
Second lien: a loan recorded behind the first mortgage. If the property is sold or foreclosed, the first mortgage is paid first.
Stress payment: the payment the lender uses to test the rent. Here it is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points.
Draw period: the stretch when you can borrow from the line and pay interest only on the drawn balance. Here it lasts 5 years.
Seasoning: a waiting period tied to when you bought or refinanced the property, covered in its own section below.
What Sets the Equity Ceiling?
The equity ceiling is the property’s value times the program’s combined leverage ceiling, minus every lien already recorded. The percentage does the first cut. Your existing debt does the second.
Run it in percentages of value. Say your first mortgage sits at 45% of value and your score is 720 or better. A 70% CLTV ceiling leaves 25 points of value for the line. If the first mortgage sits at 70% of value or more, a 70% ceiling leaves nothing.
Leverage tiers are firm, and they depend on the lien position:
| Lien | Credit score | Ceiling | Line size |
|---|---|---|---|
| Second lien (you keep a first mortgage) | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien (no mortgage) | 740 or better | 75% LTV | Up to $500,000 |
| First lien (no mortgage) | 700 to 739 | 70% LTV | Up to $500,000 |
| First lien, larger line | 720 or better | 65% LTV | Above $500,000 to $1,000,000 |
A borrower who keeps a first mortgage can only take a second lien, and that route starts at 720. A first lien exists only on a rental with no mortgage. Below 720 on a second lien, there is no cell in the grid.
Two adjustments can lower the ceiling further. A property in a market flagged as declining carries a ceiling 5 points lower. The tiers also apply to every eligible property type, so a condominium does not get its own higher number.
Why Does the Rent Test Use the Whole Line?
The rent test sizes the payment on the entire credit limit, whether or not you plan to draw all of it. The lender divides gross monthly rent by the stress payment, and the result must reach at least 1.10x. A bigger line therefore costs you coverage even if you never touch the extra dollars.
Rent is 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 property can have at most one vacant unit.
Taxes and insurance are not part of the qualifying payment. The payment is principal and interest on the full line at the stress rate. On a second lien, confirm on the file how the lender treats the first-mortgage payment, because the lender’s own coverage calculation governs.
The math scales in a straight line. Double the line and the qualifying payment doubles, so the coverage ratio is cut in half. A line that tests at 2.2x at one size tests at 1.1x at twice that size. Run the test backward and you get the largest line the rent can support: rent divided by 1.10, then divided by the payment on each dollar of line.
Your start rate also feeds this test. A higher start rate raises the stress payment and shrinks the rent ceiling. The rate and the pricing terms come with the lender’s disclosures, so read them before you pick a line size.
How Do the Three Ceilings Work Together?
You take the lowest of the three. Each one tends to bind on a different kind of property.
| Ceiling | What sets it | Tends to bind when |
|---|---|---|
| Equity | Value × leverage ceiling − all liens | The first mortgage is already large |
| Rent | Rent ÷ stress payment must reach 1.10x | Rent is thin against the line size |
| Program dollars | $500,000 on a second lien; first-lien lines to $1,000,000 at 65% | Value is high and debt is low |
Here is an illustrative walk-through. These are modeled inputs, not market data. A rental has a first mortgage at 40% of value, and the owner scores 735.
1. Equity: a second lien at 70% CLTV leaves 30 points of value, if the dollar total falls between $50,000 and $500,000.
2. Rent: say the stress test on a line that size comes back at 0.95x. To reach 1.10x, the line must shrink by a factor of 0.95 divided by 1.10, which is about 14% smaller.
3. Dollar ceiling: the shrunken line sits well below $500,000, so it does not bind.
4. Result: the rent ceiling wins, and the usable line is roughly 14% below what the equity alone would allow.
Now flip the picture, so that the rent test comes back at 1.25x. The equity ceiling then sets the line, because the rent could support a larger one. The ceiling you hit tells you what to fix. A thin equity file needs more value or a lower first balance. A thin rent file needs a smaller line or higher documented rent.
Choosing a line size is a genuine judgment call. A smaller line that clears the rent test with room to spare may serve you better than the maximum the equity allows, because lenders review the stress payment on the whole limit.
How Does Credit Change What You Can Borrow?
Credit sets which leverage tier you land in, and the lender’s own report decides it. A second lien requires a 720 score. A first lien, available only on a rental with no mortgage, starts at 700, though first-lien lines above $500,000 are held to 65% LTV at 720 or better. Exact terms depend on lender and investor guidelines, credit profile, reserves, and property review.
Most programs that write rent-qualified lines also look at mortgage history. In this lane, a 30-day late payment in the last 12 months is a problem. So is a bankruptcy, foreclosure, short sale or deed-in-lieu inside the last 48 months. Tradeline-depth rules are waived at 700 and above, which covers every score the program accepts.
A 700-to-719 borrower who keeps a first mortgage is shut out of the second-lien grid, because that tier starts at 720. If that is you, the practical routes are lifting the score or looking at a DSCR cash-out refinance instead. Lendmire’s piece comparing a DSCR HELOC with a DSCR cash-out refinance walks through that tradeoff.
Why Is So Much of the Line Drawn on Day One?
This program requires at least 80% of the line to be 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 are at least $5,000 each.
So a DSCR HELOC works more like a loan with some flexibility than a standby reserve. The CFPB’s HELOC booklet describes a line as a loan that lets you borrow, spend and repay as you go. The draw rules here narrow how much of that flexibility you start with.
The timeline is simple. You pay interest only on the drawn balance for 5 years. Then a 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable.
Size the line to a project or a purchase you have already identified. A borrower choosing between a larger line and a smaller one should remember that the larger line lowers rent coverage.
The File Behind the Number
The valuation path depends on line size. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, paired 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.
Seasoning is the waiting period that applies here. 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).
Other file requirements are short:
- No reserves and no cash to close are required, subject to underwriting.
- Exposure is limited to 5 loans or $2,500,000 per borrower with the program.
- Eligible borrowers are U.S. citizens, permanent residents and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
- Hazard insurance must cover both liens, with flood coverage where required.
Eligible properties include single-family homes, PUDs, townhomes, two-to-four-unit buildings, warrantable and non-warrantable condominiums, and lots up to 10 acres. Several property types fall outside this lane:
- Rural-designated property, row homes and condotels
- Commercial, agricultural and mixed-use property
- Leaseholds, land trusts and age-restricted communities
- Hobby farms, modular and log homes, and land-contract deals
- A property listed for sale in the prior 2 months
- A property with a solar lien
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is the broker, and the line is placed through a wholesale lender in its network.
When the Numbers Don’t Fit
Sometimes the three ceilings combine to a line too small to matter. The line has a $50,000 floor, so a thin equity file may produce no workable line at all.
Three common patterns come up:
- The first mortgage is too high. A first mortgage at 70% of value or more leaves nothing under a 70% CLTV ceiling on a second lien. Paying the balance down or waiting for appreciation are the usual paths, and a cash-out refinance of the whole property is the alternative if you would rather replace the first mortgage.
- The rent is too thin for the full limit. Take a smaller line or document higher rent through three months of receipts when the lease runs above market.
- The property sits in an excluded category. A row home, a condotel or a rural-designated property needs a different structure altogether.
Another route is to hold the first mortgage and use the line only for equity that a refinance would wipe out. If your first mortgage carries a rate you like, that is a real reason to prefer the line. Whether the variable rate on drawn dollars is worth that trade is a model you should run on your own numbers, not a rule of thumb.

Frequently Asked Questions
Can I get a DSCR HELOC if I still have a mortgage on the rental?
Yes, as a standalone second lien behind your existing first mortgage, which stays in place. The second-lien route requires a 720 credit score or better and reaches up to 70% combined loan-to-value, on lines from $50,000 to $500,000, subject to underwriting. The first mortgage’s borrowers do not have to be the same as the borrowers on the line. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Does the rent test use what I draw or the full credit limit?
It uses the full credit limit. The qualifying payment is principal and interest on the entire line at the start rate plus 2 percentage points, and gross monthly rent must cover it at 1.10x or better. Taxes and insurance are not part of that payment. Confirm on the file how the lender treats the first-mortgage payment on a second lien.
How does seasoning work on this line?
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 must be satisfied before the file is eligible. Confirm your dates against the program sheet before you apply.
What happens to my available line if the variable rate rises?
The rent test is run when you apply, using the stress payment at the start rate plus 2 percentage points. After closing, the variable rate changes your carrying cost on the dollars you have drawn. The lender’s HELOC disclosures explain how the rate adjusts, and you should read them before you choose a line size.
Can my LLC hold title to the property?
Yes, subject to program terms. Vesting in your LLC is allowed on investment property, and the members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
