The Quick Read: It depends on which of three limits binds first: the combined loan-to-value ceiling (70% on a second lien at a 720 credit score or better), the program’s line-size cap ($50,000 to $500,000 on a second lien), or the rent coverage test of 1.10x, which runs on the entire credit limit rather than the amount you draw. Your line is the smallest answer the three tests give. All figures below come through select programs and are subject to underwriting. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
- Second lien (you keep your first mortgage): up to 70% combined loan-to-value at 720 or better, on lines of $50,000 to $500,000.
- First lien (a rental with no mortgage): up to 75% loan-to-value at 740 or better, and 70% at 700 to 739, on lines up to $500,000. Lines above $500,000 and up to $1,000,000 carry a 65% ceiling at 720 or better.
- Coverage: the rent must reach a 1.10x minimum against a stress payment on the full line.
- Short-term rental income: higher Airbnb revenue does not automatically raise the line. The rent the lender counts is capped by the lease and the appraiser’s market rent, as explained below.
Key Terms Defined
Seven terms carry this topic. Each gets one plain definition here and none after.
- DSCR (debt-service coverage ratio): the rental’s monthly rent divided by the monthly payment the lender counts against it.
- HELOC: a revolving line of credit secured by property, which you borrow from, repay, and borrow from again during a set draw window.
- Lien position: your place in line if the property is ever sold to pay debts. A first lien is paid first. A second lien sits behind it.
- Combined loan-to-value (CLTV): your first mortgage balance plus the new line, divided by the property’s value.
- Loan-to-value (LTV): the same idea when there is only one loan on the property.
- Draw period: the stretch of years when you can pull money from the line and pay interest only on what you have drawn.
- Stress payment: a fully repaying payment calculated on the whole credit limit at the starting rate plus 2 percentage points. It is a test number, not what you pay.
Which Limit Wins: Equity, Coverage, or the Line Cap?
Equity sets the first ceiling, coverage trims it, and the dollar cap trims it again if the property is large. Take the lowest of the three. Most borrowers who run into trouble on a rental line hit the coverage test before the equity test.
Start with equity. On a second lien, the formula is value times the allowed CLTV, minus what you owe on the first mortgage. Say a rental has a first mortgage at 40% of its value. At a 70% ceiling, that leaves room for a line worth about 30% of value. A declining-market flag on the property can lower the ceiling by 5 points, which would pull that room to about 25%.
Now the line cap. A second lien runs from $50,000 to $500,000. On a high-value property, that cap can bind before equity does. A line that sits well under both limits has the easiest time at the coverage test.
Credit matters in one place: tier access. A second lien needs a 720 score, and there is no second-lien cell below that. Owners who keep a first mortgage can only take a second lien. A first lien exists only on a rental with no mortgage at all, with a 700 minimum score.
Paid off does not mean unlimited. A free-and-clear rental still faces the LTV ceilings and the line caps. At 740 or better, a first lien reaches 75% LTV on lines up to $500,000. At 700 to 739, it reaches 70%. Larger first-lien lines, above $500,000 and up to $1,000,000, step down to a 65% ceiling at 720 or better. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

How the Coverage Test Shrinks Your Line
The coverage test runs on the whole credit limit, not on the balance you draw. A bigger line means a bigger stress payment, which means a lower coverage number. That is the part many owners miss.
The math has three pieces:
1. The rent. 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.
2. The payment. The qualifying payment is principal and interest on the full line at the stress rate. Taxes and insurance are not part of it.
3. The ratio. Gross monthly rent divided by that payment must reach 1.10x.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. That detail changes the result, and the lender’s own calculation governs. All of this qualifying arithmetic is illustrative.
Here is what that means in practice. A rental that clears the test at one line size can fail at a larger one. If it fails, the fix is usually a smaller line, not a different story about the rent. Sizing the line near what you actually need protects both coverage and your carrying cost.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The rental qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. There is no traditional personal-income documentation, meaning no W-2s and no personal income calculation, and an LLC can stay on title.
Does Higher Airbnb Revenue Raise the Line?
Not by itself. Short-term rental revenue can help a file, but the rent used for lender review is tied to the lease and the appraiser’s rent schedule. Gross platform income does not simply replace them.
Here is the practical picture. The appraiser’s rent schedule is built for long-term rent. On a short-term rental, that figure often lands below what the property earns on a booking platform. Since the coverage figure is the lesser of that market rent and the lease, an Airbnb-strong property can still test lighter than its real income suggests, unless three months of rent receipts support a lease above market.
Which income evidence a given lender accepts on a short-term rental file varies, and it is worth confirming before you pay for anything.
Revenue swings matter too. Short-term rental income is volatile, and a coverage ratio built on it can move a lot depending on which income method is used. Plan around the lower number.
Two property rules catch short-term rental owners. Condotels are not eligible, and a property listed for sale in the prior two months is out.
DSCR HELOC, Personal-Income HELOC, or Cash-Out Refinance?
The three products answer different needs. A cash-out refinance replaces the first mortgage. A personal-income investment HELOC qualifies the borrower instead of the property.
| Factor | DSCR HELOC | Personal-income investment HELOC | DSCR cash-out refinance |
|---|---|---|---|
| Reviewed on | Rent coverage | Credit, DTI, income | Rent coverage |
| Your first mortgage | Stays in place | Stays in place | Replaced |
| LLC on title | Allowed | Not allowed on this program | Varies by program |
That LLC row is the one that matters to many owners. The personal-income investment HELOC on Lendmire’s network requires title in an individual or revocable trust. The DSCR HELOC allows an LLC, subject to lender program eligibility. Members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment.
When the line is too small for your goal, a cash-out refinance is the alternative. It swaps out the first mortgage, so it only makes sense if the existing loan is not one you want to keep.
What the File Looks Like
A rental HELOC file asks for a current first-mortgage statement, an insurance declaration, and the vesting deed. Across Lendmire’s wholesale network, the other requirements are fairly consistent.
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 need a full interior appraisal. Appraisal waivers are not accepted.
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).
Credit and history. The minimums are 720 on a second lien and 700 on a first lien. The program looks for no 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu. No reserves and no cash to close are required.
Exposure. Each borrower can hold at most 5 loans or $2,500,000 with the program.
Property. Single-family, PUD, townhome, two-to-four-unit, and condominium properties are eligible. Rural-designated property, row homes, condotels, leaseholds, land trusts, mixed-use, and properties with a solar lien are not.
Borrowers. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
Where it is offered. The program runs in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is the broker. It arranges the line through a wholesale lender, and the lender decides.
How the Draw and Repayment Work
You do not get to leave the line mostly unused. 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.
The structure runs on a 5-year draw period, interest only on the drawn balance. Then comes a 25-year fully repaying period, with a 30-year maturity. The rate is variable.
That has three consequences. Interest starts on day one, so the closing draw is not a reserve you leave untouched. Payments can rise even if you borrow nothing more. And a second payment on the rental cuts into the cash flow that supports your coverage.
The Consumer Financial Protection Bureau describes a HELOC as an open-end line with a draw period followed by a repayment period, and warns that you could lose the property if you cannot repay. Its HELOC brochure adds that the terms of a line can prohibit renting out the property. That brochure is written for owner-occupied homes, and a rental line works differently. It is still smart to read the note and your insurance policy for a short-term rental use clause.
Stacked debt is the trade-off. A line keeps your existing first mortgage intact, but it adds leverage on top of it. NerdWallet notes that investment-property HELOCs mean a smaller lender pool and less borrowing than on a primary home.
When the Numbers Don’t Fit
If the line comes out smaller than you wanted, you have four honest options.
- Shrink the line. A smaller limit lowers the stress payment and raises coverage. This is the cleanest fix when coverage is the binding limit.
- Check the leverage tier. A rental with no mortgage may qualify for a first lien, which reaches higher leverage than a second lien. If you hold a first mortgage, only the second lien is open to you.
- Change the product. A cash-out refinance replaces the first mortgage, so it can make sense when the existing loan is not worth keeping.
- Wait out the clock. Seasoning, a recent late payment, or a past credit event can all be time problems rather than math problems.
One more reality check. Using one rental’s equity to fund the next purchase can work, but the line is never closed together with a purchase. You draw the money first, then buy.
Frequently Asked Questions
Is coverage tested on what I draw or on the whole line?
On the whole line. The qualifying payment is a fully repaying payment on the entire credit limit at the starting rate plus 2 percentage points. A larger line therefore lowers coverage even if you plan to draw only part of it. Sizing the limit near your real need keeps the ratio healthier.
Does a higher credit score raise how much I can borrow?
Only up to the tier. On a second lien, 720 or better unlocks the 70% combined ceiling, and there is no second-lien cell below 720. On a first lien, 740 or better reaches 75% and 700 to 739 reaches 70%, on lines up to $500,000. Beyond those cutoffs, a higher score does not add leverage.
Can my LLC hold title?
Yes. The DSCR HELOC allows vesting in the owner’s LLC on investment property, subject to lender program eligibility. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment. The borrowers on the line need not 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 must be satisfied before the file can move forward.
Can I borrow against an Airbnb with no booking history?
The program requires a lease in place and a market rent from the appraiser, so history on a booking platform is not the only gate. A brand-new listing is not automatically out, but how a lender counts short-term income varies by file. Confirm the rent method before ordering a valuation.
