The Quick Read: A DSCR HELOC is a revolving line of credit on a rental you already own, and on a short-term rental the equity left after your first mortgage sets how much you can borrow, while the rent only decides whether the line clears the coverage test. Everything below is subject to underwriting and lender guidelines, and every file is reviewed individually.
- The line sits behind your first mortgage as a standalone second lien, or stands alone as a first lien on a rental with no mortgage.
- The rental’s rent qualifies it. No traditional personal-income documentation, W-2s or personal income calculation are involved, subject to lender guidelines.
- Through select programs, a second lien reaches up to 70% combined loan-to-value at a 720 credit score or better, on lines of $50,000 to $500,000.
- Equity usually binds first. Strong rent coverage cannot create borrowing room that the equity math has already used up.
- The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
What Is a DSCR HELOC on a Short-Term Rental?
A DSCR HELOC is a home equity line of credit written on a non-owner-occupied rental and qualified on the property’s rent instead of your paycheck. DSCR stands for debt service coverage ratio, which is the rental’s monthly rent divided by the monthly payment the lender tests.
Two details matter on day one. First, this is business-purpose lending on an investment property. It is a different product from the line a bank writes on the home you live in, and it is never offered on an owner-occupied home or a second home. Second, the line can be vested in your LLC, subject to program terms, with the members signing as guarantors.
The structure is simple. You keep your first mortgage, and the line sits behind it as a second lien. If the rental has no mortgage, the line can stand alone as a first lien. It is never closed together with a purchase, and it is never a third lien.
The word “short-term” changes less than most investors expect. The product does not care whether guests or a long-term tenant pay the bills. It cares about equity, coverage, credit and what the file can document. Your short-term rental simply gets read through a rent figure, and that is where things get interesting.
How Does Underwriting Treat It, Step by Step?
Underwriting follows a fixed order: it checks eligibility, measures value, sets rent used for lender review, runs the coverage test, then sizes the line against equity. Each step can stop the file, and each one is more mechanical than most borrowers assume.
1. Eligibility. The property must be a one-to-four-unit rental, such as a single-family home, townhome, PUD, condominium or two-to-four-unit building. Rural-designated property, condotels, row homes and leaseholds sit outside this lane. A two-to-four-unit building may have at most one vacant unit.
2. Seasoning. 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).
3. Valuation. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
4. Rent used for lender review. 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.
5. The coverage test. The minimum is 1.10x. The lender divides gross monthly rent by a qualifying payment. That payment is a fully amortizing principal-and-interest payment on the entire credit limit, at the start rate plus 2 percentage points. It is a stress payment, not the payment you will actually make. Taxes and insurance are not part of it.
6. Credit. A second lien needs a 720 score. A first lien needs 700. Mortgage history shows no 30-day late in the last 12 months, and 48 months must have passed since a bankruptcy, foreclosure, short sale or deed in lieu.
7. Sizing. Equity caps the line, as the next section shows.
One open point deserves a plain statement. On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. The lender’s own calculation governs, and any worked arithmetic in an article like this one is illustrative.
How Is Borrowing Power Actually Calculated?
Borrowing power equals value times the combined-leverage ceiling, minus what you already owe on the property. Rent coverage works as a gate you must pass first, and equity decides how far through the gate you can walk.
On a second lien, the ceiling is 70% combined loan-to-value (CLTV). CLTV adds your first mortgage balance and the new line together, then divides by the property’s value. On a first lien with no mortgage, the ceiling is 75% loan-to-value (LTV) at a 740 score or better, and 70% LTV from 700 to 739. First-lien lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Run it in percentages. Say a rental’s first mortgage sits at 50% of value. A second-lien line can then take up to 20 points of value, subject to underwriting. Say the first mortgage sits at 68% of value, as often happens after a recent high-leverage purchase. Only 2 points of room remain, which cannot support the $50,000 minimum line. The rent could cover the stress payment several times over, and the borrowing room would still be zero.
That is the gap most investors miss. Two things control the answer:
| Constraint | What it decides | Typically binds when |
|---|---|---|
| Equity (CLTV or LTV ceiling) | The maximum line size | Your first mortgage is large relative to value |
| Rent coverage (1.10x stress test) | Whether the line is approved | Rent is thin against a large line |
| Credit tier | Which ceiling applies | Your score sits near a tier break |
Coverage can also bind, because the stress payment is calculated on the whole credit limit, not only what you draw. A bigger line raises the test payment. Sometimes the right move is a smaller line that clears the test comfortably.
How Do Lenders Read Short-Term Rental Income?
For this line, the rent used for lender review comes from the lease and the appraisal’s market rent, and that is the part short-term rental owners need to plan around. Your booking history is useful evidence, but the program’s rent test works from the figures above.
This has a practical effect. An appraisal form built on long-term lease comparables can understate what a short-term rental actually earns. Class Valuation, an appraisal management firm, explains that the standard 1007 rent schedule is built for long-term leases and often produces an artificially low result on a short-term rental. Appraisers use a separate short-term income analysis instead.
So confirm on the file how the lender treats a short-term rental. Across our wholesale network, programs differ on this point. Some read the rent through a lease and market rent only, and others weigh documented booking history more heavily. The line described here requires a lease in place, so ask early which document the lender will count.
Seasonality adds a second wrinkle. A trailing window that captures a peak season can flatter your coverage. Before you apply, check how the rent figure holds up in your weakest month, because your own cash flow has to survive the slow season even when the lender’s test passes.
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. A lost permit changes the income your line was sized against.
How Do the Draw and Repayment Phases Work?
The line has a 5-year interest-only draw period, then a 25-year fully amortizing repayment period, for a 30-year maturity. The rate is variable.
Most of the line is funded at the start. At least 80% of it 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.
This differs from the picture many investors carry from a home equity line on their own house. As the FTC explains, you pay interest only on the amount you actually borrow, and the payment typically moves with a variable rate. Here, because most of the line is drawn up front, you should plan for interest on nearly the whole line from day one.
Two cautions follow. The payment can change even if you never draw again, because the rate is variable. And when the draw period ends, principal payments begin, so the monthly obligation steps up. Passing the 1.10x stress test is not the same as having positive cash flow after that step-up. Compare the real payment to your net operating income, not just the lender’s ratio.
The Consumer Financial Protection Bureau notes that a lender may refuse further draws if the property’s value drops significantly. That is generic HELOC behavior, and it is a good reason not to plan a project around draws you have not yet taken. The rate and pricing terms come with the lender’s disclosures.
Where Does the General Rule Break?
The general rule says strong rent plus equity equals a line. Several named edge cases break it.
- A fresh purchase. A rental bought or refinanced in the last 6 months is outside the program. Even after that, a high-leverage purchase usually leaves little combined-leverage room.
- A new listing with no lease. A lease in place is required. A property listed for sale in the prior 2 months is also ineligible.
- A first mortgage and a 700-719 score. A second lien needs 720. A first lien needs no existing mortgage, so a 700-719 borrower with a mortgage on the property has no route here.
- Declining markets. A declining-market flag lowers the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower.
- Property type. Rural-designated property, condotels, row homes, leaseholds, land trusts, mixed-use and age-restricted communities are not eligible on this lane. Short-term rental properties are often condotels or resort-area condominiums, so check the property type before you spend on an appraisal.
- Borrower type. Foreign nationals and ITIN borrowers are not eligible. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are.
- Exposure. The program caps each borrower at 5 loans or $2,500,000.
- Vested title. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument, so your LLC arrangement needs to be clean.
Think of it this way: most failed files fail on property type, seasoning or equity, not on rent.
How Does It Compare With Other Ways to Reach Equity?
Each way of reaching equity solves a different problem. This table describes each product’s general structure, not this program’s rules.
| Option | Collateral | First mortgage | Funding shape |
|---|---|---|---|
| DSCR HELOC | The rental | Stays in place | Revolving line, most drawn at closing |
| DSCR cash-out refinance | The rental | Replaced | One lump sum, one new loan |
| Investment-property HELOC on personal income | The rental | Stays | Revolving, qualified on your income per that program’s rules |
| Primary-residence HELOC | Your own home | Stays | Revolving, owner-occupied product |
A primary-residence HELOC puts your own home behind your rental, which is a real risk if the rental stumbles. A cash-out refinance can make sense when your existing first mortgage is expensive, since a line leaves that mortgage untouched. When your first mortgage is a good one, a second lien lets you keep it. Weigh a blended cost, since keeping a low first mortgage and adding a higher-cost second can still cost more than the alternatives. Lendmire’s pages on DSCR cash-out refinances and the complete DSCR loans guide cover the other paths in more depth.
What Does the Investor Decision Look Like in Practice?
The decision follows a short checklist. Run it in order.
1. Check eligibility first. Property type, ownership, seasoning, credit tier and state are binary gates.
2. Check equity second. Estimate value, subtract your first mortgage balance, and see whether the leftover room clears the $50,000 line minimum.
3. Check the rent figure third. Ask which documents the lender will count for a short-term rental, and whether your lease and the appraisal’s market rent produce a 1.10x or better test on the full line.
4. Check your own cash flow last. Run the draw payment against a slow month, then against the larger repayment-period payment.
People use the money for renovation, furnishing, reserves on other properties or the down payment on the next rental. Whatever the use, you are creating two approvals if you buy again: the line on the existing rental, and the loan on the new one. Both must hold.
This is the wrong tool when your equity room is under the minimum line, when the property is a condotel or in a rural designation, when you are inside the seasoning window, or when the only way to pass the test is a rent figure your slow months cannot support.

Second lien: a loan that sits behind your first mortgage and is repaid after it if the property is sold.
Draw period: the stretch when you can borrow from the line and pay interest only on what you have drawn.
Stress payment: the payment the lender uses in the coverage test, calculated on the full credit limit and higher than your actual payment.
Form 1007: the appraiser’s market rent schedule, built on long-term rental comparables.
Frequently Asked Questions
Can a brand-new Airbnb qualify?
Rarely. 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). A lease in place is also required.
Does the line count my booking history as income?
That depends on how the lender treats short-term rental on the file. This program’s rent figure comes from the lease and the appraisal’s market rent. Ask early which documents will count, because a standard rent schedule can understate a short-term rental.
Can my LLC hold the line?
Yes, subject to program terms. The rental can be vested in your LLC, the members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment.
Will it replace my first mortgage?
No. As a second lien, it sits behind the first mortgage you keep. A first lien exists only on a rental with no mortgage.
How much can I borrow on a short-term rental?
Lines run from $50,000. A second lien reaches up to 70% CLTV at a 720 score or better, up to $500,000, subject to underwriting. Your borrowing room is that ceiling applied to value, minus your first mortgage balance.
