The Quick Read: Usually up to 70% of the rental’s value on a second lien, minus what you still owe on the first mortgage, capped at $500,000 and limited by whether the rent covers a stress payment on the whole line. A rental with no mortgage can reach 75% of value at the top credit tier. All figures are ceilings through select programs, subject to underwriting.
- Equity sets the first limit. On a second lien behind your existing mortgage on a non-owner-occupied rental, combined loan-to-value (CLTV) tops out at 70% at a 720 credit score or better.
- Rent sets the second limit. The rent must cover at least 1.10x a stress payment on the entire credit limit, not just the part you draw.
- Your own income is not part of the test. The line qualifies primarily on property-level rental income, subject to lender guidelines.
- Size has floors and ceilings. Lines start at $50,000, and a second lien runs to $500,000.
- Availability is limited. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Two Limits Decide Your Number
Your line is the smaller of two results: the equity ceiling and the rent ceiling. Run the equity math first, because it is simple and it often settles the question before rent matters.
The equity formula works like this. Take the property’s value and multiply it by the allowed combined leverage. Subtract every lien already on the property. What remains is the most the lender could extend, before any dollar cap.
The closer the first mortgage sits to the combined ceiling, the less room remains for a second lien. If the first mortgage reaches that ceiling or goes higher, there is no room at all.
The combined loan-to-value ceiling is shared with your first mortgage. The first lien uses up its part before the line gets a dollar. That is why two rentals with the same value can produce very different lines.
Rent comes second. Even with plenty of equity, the line shrinks if rent cannot support the stress payment on the full limit. Both tests must clear, subject to lender guidelines.
What Does “DSCR HELOC” Actually Mean?
No regulator defines the term, and the label gets used for two different products. The first is a line on a rental, sized by combined leverage and qualified on rent coverage. The second is a conventional investment-property HELOC underwritten on your personal credit and debt load.
This article covers the first kind. A DSCR HELOC here is a revolving line secured by a rental you keep. It is written as a standalone second lien behind your first mortgage, or as a standalone first lien on a rental with no mortgage. It is never a line on your own home.
The second kind is harder to pass. NerdWallet notes that an investment-property HELOC is harder to get than one on a primary home because lenders see higher default risk, and that not every lender offers one. Bankrate says lenders weigh both your creditworthiness and the property’s financials.
The White Coat Investor lists a 720 credit score, six months of reserves, debt-to-income of 50% or less and loan-to-value of 80% or less for investment HELOCs underwritten on the owner’s finances. That describes that product’s rules, not this one’s. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
The rent-qualified line works differently. It needs no traditional personal-income documentation, W-2s, pay stubs or debt-to-income ratio. It also needs no reserves. For the broader picture of rent-based investor loans, see the complete DSCR loans guide.
How Does the Rent Test Shrink the Line?
The rent test sizes the line against the full limit, not the drawn balance. The coverage ratio is gross monthly rent divided by the qualifying payment, and it must reach at least 1.10x. The qualifying payment is a fully amortizing principal-and-interest payment on the entire credit limit, calculated at the starting rate plus 2 percentage points. Taxes and insurance are not part of it.
That stress feature matters. A $500,000 limit is tested as if all of it were drawn, even though you may draw only part of it. A bigger line means a bigger stress payment and a harder coverage test.
Rent is the lesser of the appraisal’s market rent (Form 1007) 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 may have at most one vacant unit.
One point needs checking on the file. Confirm how the lender treats the first-mortgage payment in the coverage calculation on a second lien. The lender’s own calculation governs, and any example here is illustrative.
So which limit binds? Compare the two results. If the equity ceiling comes out lower, equity is your constraint. If the rent-supported amount comes out lower, rent is. Raising rent to market, or asking for a smaller limit, moves the second number. Paying down the first mortgage moves the first.
Worked Examples (Percentages, Not Dollars)
These examples use a rental valued at 100 units and assume a qualifying credit score. They are illustrations, and the lender’s calculation governs.
| Scenario | Equity ceiling | What binds |
|---|---|---|
| Second lien, first mortgage at 50 | 70 CLTV, so 20 of room | Equity, then rent |
| Second lien, first mortgage at 65 | Only 5 of room | Equity |
| Second lien, first mortgage at 70+ | No room | Equity |
| Paid-off rental, 740+ score | 75 LTV on a first lien | Equity or rent |
| Paid-off rental, 700–739 score | 70 LTV on a first lien | Equity or rent |
The row for a second lien behind a first mortgage at 65 deserves a closer look. If the room left over converts to less than a $50,000 line, no line exists, because lines start at $50,000. High leverage can leave a rental with equity on paper and no usable line.
Now take a case where rent binds. A rental has 20 units of equity room, but the rent barely covers a stress payment on the full line. The lender may support a smaller limit, or none. This is where a free-and-clear, high-value rental can disappoint. The equity is there, but the coverage ratio is not.
Size Your Own Line in Five Steps
1. Estimate value. Use a realistic current value, since the lender orders its own valuation and may differ from your estimate.
2. Pick the leverage tier. Second lien: 70% CLTV at 720 or better. First lien on a rental with no mortgage: 75% LTV at 740 or better, or 70% LTV from 700 to 739.
3. Subtract existing liens. Take value times the tier, then subtract the first-mortgage balance.
4. Check the limits. The result must be at least $50,000, and a second lien tops out at $500,000.
5. Test the rent. Divide gross monthly rent by the stress payment on the whole limit. You need 1.10x or better. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
If the rent test fails, lower the limit and test again. A smaller line has a smaller stress payment.
Second Lien vs. First Lien: Which Applies to You?
Your lien position follows from what you owe, not from what you prefer. If you keep a first mortgage, the line is a second lien, and the credit floor is 720. A first lien exists only on a rental with no mortgage, and its floor is 700.
| Item | Second lien | First lien |
|---|---|---|
| Rental has | A first mortgage you keep | No mortgage |
| Leverage | 70% CLTV at 720+ | 75% LTV at 740+; 70% LTV at 700–739 |
| Line size | $50,000 to $500,000 | $50,000 to $1,000,000 |
| Larger lines | Not available above $500,000 | 65% LTV at 720+ above $500,000 |
Subject to underwriting, a first-lien line above $500,000 carries the 65% LTV ceiling, so a high-value paid-off rental may reach less leverage on a larger request than on a smaller one. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
A declining-market flag lowers the ceiling by 5 points, and other local overlays can lower it further.
How Do Draws Affect What You Actually Borrow?
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 are at least $5,000 each.
This is not a line you open and leave idle. If you want a standby reserve for a rainy day, this structure may not fit. If you want most of the money now for a down payment or a renovation, it fits better.
The draw period is 5 years, interest-only on the drawn balance. A 25-year fully amortizing repayment period follows, and the maturity is 30 years. The rate is variable, so the payment can change. The rate and the pricing terms come with the lender’s disclosures.
Plan for the payment step-up when repayment begins. Interest-only payments cover no principal, and the amortizing period starts with a higher payment on the same balance. Model it before you draw.
What Else Can Reduce or Block the Line?
Several file items trim the number or end the request.
Valuation. Lines up to $400,000 use 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. Appraisal waivers are not accepted. A low valuation lowers the equity ceiling.
Seasoning. The waiting period has one rule with two clocks: 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).
Property type. Single-family, PUD, townhome, two-to-four-unit properties and condominiums are eligible, and so are lots up to 10 acres. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, mixed-use and a property listed for sale in the prior 2 months fall outside this lane. So does a property with a solar lien.
Credit history. The program wants no 30-day mortgage late in the last 12 months. It also wants 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
Entity and borrower. An LLC can hold title, subject to program terms. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment. The program serves U.S. citizens, permanent residents and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Exposure. A borrower can hold at most 5 loans or $2,500,000 with the program. If you plan several lines across a portfolio, add them up first.
How Does It Compare With Other Ways to Pull Equity?
The right tool depends on whether you want to keep the first mortgage and whether you want the owner’s income in the file.
| Factor | DSCR HELOC | DSCR cash-out refinance | Personal-income investment HELOC |
|---|---|---|---|
| First mortgage | Stays in place | Replaced | Stays in place |
| Qualified on | Rent coverage | Rent coverage | Credit and DTI (their rules) |
| Structure | Revolving, variable | One new loan | Revolving (varies by lender) |
| Best when | First mortgage is worth keeping | You want one new loan | Personal income is strong |
A DSCR cash-out refinance makes sense when you want to replace the first mortgage and take cash in one transaction. A line makes sense when the existing first mortgage is worth keeping. A primary-residence HELOC is a different, owner-occupied product, and this line is never offered on an owner-occupied home. If a lender will not lend against the rental, Bankrate suggests borrowing against your own home, which carries its own risk to the home you live in.

The Risks and the Exit Plan
A line on a rental puts a lien on a property you rely on for income. Think through four risks before you draw.
- Variable payments. The rate is variable, so the monthly obligation can rise.
- Payment step-up. Repayment starts after 5 interest-only years and brings principal into the payment.
- Vacancy. A stretch without tenants still leaves a payment due.
- Combined leverage. Two liens on one rental leave a thinner cushion if values fall.
Draw only for uses that produce income or build value, and stress-test the payment against a vacancy period. Have an exit plan: a refinance, a sale, or paydown from the next property’s cash flow. That last route only works if the rental bought with the draw can carry itself, so money used for a down payment on another rental needs that property’s income to cover its own payment.

Frequently Asked Questions
How much can I borrow on a rental with a mortgage?
Take 70% of the value, subtract the first mortgage balance, and the remainder is your ceiling. That 70% is CLTV on a second lien on a non-owner-occupied rental, at a 720 credit score or better, and lines run from $50,000 to $500,000. The rent must also cover 1.10x the stress payment on the whole line, subject to underwriting. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Can I get a line on a rental held in my LLC?
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. This line is for investment property only.
How soon after buying a rental can I open a 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).
Does my personal income matter?
The line qualifies primarily on property-level rental income covering the stress payment, subject to lender guidelines. Tax returns, W-2s, pay stubs and a debt-to-income ratio are not part of the test. Your credit score, mortgage history, the lease, and the valuation are all documented.
What if my first mortgage uses up most of the equity?
Then the room left may be small or zero. A second lien must reach at least $50,000, so thin room can mean no line. Paying down the first mortgage, waiting for value to rise, or looking at a cash-out refinance are the usual alternatives.
