The Quick Read: It depends first on equity: the line is capped by combined loan-to-value (the first mortgage plus the new line, divided by value), up to 70% CLTV on a second lien at a 720 score, and then rent must cover a stress payment on the whole line at 1.10x, subject to lender guidelines. Strong rent clears the test, but it does not make the line bigger.
- Equity sets the ceiling. Property value times the allowed combined leverage, minus every lien already on the rental, is the most the line can be.
- Rent is a pass-or-fail gate. The test runs on the entire credit limit, not only the amount you draw.
- A second lien runs from $50,000 to $500,000. A first lien on a rental with no mortgage can reach $1,000,000, with a 65% LTV ceiling above $500,000.
What Is the Maximum?
Two gates decide how much you can borrow, and the lower one wins.
The most you can borrow is the lowest of three numbers: the equity ceiling, the program’s dollar cap, and the largest line your rent can support. Investors with thin rent against a large line hit the rent test first.
Think of it as two gates in a row. Gate one asks how much room is left between your first mortgage and the leverage cap. Gate two asks whether the rent covers the payment on a line that size. Both must pass, and the smaller answer becomes your limit.
This is a DSCR product, which Lendmire’s complete DSCR loans guide covers in more depth. 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.
Key Terms Defined
DSCR (debt-service coverage ratio): the property’s gross monthly rent divided by the payment the lender uses to test it. A 1.10x result means the rent is 110% of that payment.
CLTV (combined loan-to-value): the first mortgage balance plus the full new line, divided by the property’s value. First-lien lines use plain LTV, because there is only one loan.
Second lien: a loan that sits behind your first mortgage. You keep the first mortgage untouched, and the new line is paid after it if the property is ever sold.
Stress payment: a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It is a test payment, not what you will necessarily pay.
Form 1007: the appraiser’s single-family market-rent schedule. Form 1025 serves two-to-four-unit properties.
Gate One: Equity Sets the Ceiling
Your line cannot exceed value times the allowed combined leverage, minus what you already owe. On a second lien, the allowed leverage tops out at 70% CLTV at a 720 credit score or better. Below 720 there is no second-lien tier at all. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
The arithmetic works in points of value. Say your first mortgage sits at 50% of the property’s value. A 70% ceiling leaves 20 points of value for the new line. A first mortgage at 60% leaves 10 points. A first mortgage at 70% or higher leaves nothing.
That last case catches recent buyers. A rental purchased with a high-leverage first mortgage often starts at or above the ceiling. There is no line until paydown or appreciation pulls the CLTV back under it.
Thin slices matter for another reason. Lines start at $50,000, so a small sliver of equity may not reach the minimum size.
A declining-market flag on the property can lower the ceiling by 5 points. That is one more reason to treat every figure here as a ceiling, never an offer.
Banks follow the same logic with different numbers. An investor on BiggerPockets reports a bank capping one rental at 75% CLTV, which is a market anecdote and not this program.
First Liens on Paid-Off Rentals
A first lien exists only on a rental with no mortgage. If you keep a first mortgage, often a strong option is a second lien at 720 or better. These are the first-lien tiers, subject to underwriting:
| Credit score | Line size | Maximum LTV |
|---|---|---|
| 740 or better | Up to $500,000 | 75% |
| 700 to 739 | Up to $500,000 | 70% |
| 720 or better | Above $500,000 to $1,000,000 | 65% |
Write these as LTV on a first lien and CLTV on a second lien, because the two are not interchangeable. A 700-to-739 borrower with a paid-off rental gets 70% LTV. A borrower in that range who still has a mortgage cannot take a second lien at all, because the second-lien floor is 720. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Gate Two: Rent Tests the Whole Line
Rent has to reach 1.10x against the stress payment on your full credit limit. You might draw only part of the line over time, but the test assumes you borrow all of it.
Two things follow from that. A bigger line raises the rent hurdle, because the test payment grows with the limit. And a line sized “just in case” can fail a test that a smaller line would pass.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A two-to-four-unit rental may have at most one vacant unit.
The qualifying payment is principal and interest on the full line at the stress rate. Taxes and insurance are not part of it. On a second lien, confirm on the file how the lender treats the first-mortgage payment, because the lender’s own coverage calculation governs.
Rent does not raise the line itself. Strong coverage only clears gate two. The size still comes from gate one.
Three Illustrative Files
These ratios are modeled assumptions, not market data. The lender’s own calculation governs every real file.
| File | First mortgage | Equity room at 70% CLTV | Coverage on full line | Result |
|---|---|---|---|---|
| Strong | 45% of value | 25 points | About 1.30x | Equity sets the line |
| Borderline | 55% of value | 15 points | About 1.12x | Passes, with little margin |
| Short | 50% of value | 20 points | About 0.95x | Fails at full size |
The strong file is limited only by equity. The borderline file clears, but a lower appraised market rent could pull it under 1.10x.
The short file shows the fix. Because the test runs on the full limit, a smaller line lowers the stress payment and can lift coverage past 1.10x. Higher rent or a lower first-mortgage balance can help too.
Working Backward From the Line You Want
Start with the rent that counts. Divide it by 1.10. The result is the largest stress payment the file can carry.
The lender then finds the line size whose stress payment fits under that ceiling. Run it the other way and you see the pattern. A larger target line needs more rent used for lender review, and a lower rent used for lender review forces a smaller line.
Then compare that line to the equity room from gate one. Whichever is smaller is your realistic number. If equity is the limit, more rent does nothing. If rent is the limit, paying down the first mortgage does nothing for the rent test in gate two, though it does help the equity room in gate one.
What Still Gets Documented
Qualifying primarily on property-level rental income covering the payment, subject to lender guidelines, is not the same as skipping paperwork. The file still includes the following.
- A credit report. The score sets your tier: 720 on a second lien, 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.
- A valuation. Lines up to $400,000 use an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
- Title work. 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.
- Insurance. Hazard coverage must cover both liens, plus flood coverage where required.
There are no reserve requirements and no cash to close. Each borrower is limited to five loans or $2,500,000 with the program. The line can sit in your LLC (subject to program terms), with the members signing as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
The program serves US citizens, permanent residents, and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Seasoning: Two Six-Month 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).
How the Line Behaves After Closing
At least 80% of the line is drawn at closing, and that 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 draw period is 5 years, with interest-only payments on the drawn balance. Then a 25-year fully amortizing repayment period begins, for a 30-year maturity. The rate is variable. The rate and the pricing terms come with the lender’s HELOC disclosures.
That structure shapes who the product fits. It suits an investor who knows what the money is for. A renovation, a down payment on the next deal, or a gap in a BRRRR plan fit well. Money that sits undrawn does not, since most of the line is funded up front.
The line payment does not count against the DSCR on a rental you are buying. It can count against you on any loan judged by personal debt-to-income.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
DSCR HELOC vs. Bank HELOC vs. Cash-Out Refinance
| Factor | DSCR HELOC | Bank-style rental HELOC | DSCR cash-out refinance |
|---|---|---|---|
| Reviewed on | Rent coverage | Personal income and DTI | Rent coverage |
| First mortgage | Stays in place | Stays in place | Replaced |
| Structure | Variable line | Line, varies by lender | Fixed loan |
| Fits | Equity access, keep first | Strong personal income | Reset the whole loan |
NerdWallet notes that fewer banks offer rental HELOCs, that their requirements are strict, and that some restrict by location or by whether the home is rented all year. Large retail lenders vary widely, and the line you can get at one may not exist at the next.
A rent-qualified line suits a self-employed investor whose returns show low taxable income after depreciation and write-offs. Because the review focuses on the property’s income, the owner’s returns are not calculated. Lendmire’s piece Can You Get an Investment Property HELOC Qualified on the Rent Instead of Your Tax Returns? covers that fit in detail.
If you want to keep the first mortgage, a line makes sense. If you would rather reset it, a cash-out refinance does that instead.
Four Ways to Raise Your Number
1. Pick a smaller line. The stress test scales with the limit, so a smaller line lifts coverage.
2. Document stronger rent. A lease below market rent holds your coverage down.
3. Pay down the first mortgage. That frees equity under the combined ceiling.
4. Raise the credit tier. A second-lien line needs a 720 score, and a first-lien borrower moves from 70% LTV to 75% LTV at 740. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
What Falls Outside the Program
These property types are not eligible on this lane: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts, mixed-use property, a property listed for sale in the prior 2 months, and a property with a solar lien. Single-family, PUD, townhome, two-to-four-unit and condominium properties are eligible, with lots up to 10 acres.
The line also cannot close together with a purchase, and it is never a third lien. It is never written on your own home or a second home. If your rental sits in an LLC without program eligibility, or you need more than the caps allow, a DSCR cash-out refinance is the usual alternative.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is a broker that places these lines through a wholesale lender in its network, and every file is underwritten individually.
Frequently Asked Questions
Does a bigger rent give me a bigger line?
No. Equity sets the size, and rent clears or fails the 1.10x test. Higher rent only helps if the rent test, not equity, is the binding limit on a large line.
Do I need tax returns or pay stubs?
No. Qualification doesn’t depend on traditional personal-income documentation, W-2s, pay stubs or a debt-to-income calculation, subject to lender guidelines. The lease, credit report and valuation are still reviewed.
How soon after buying a rental can I open one?
It depends on seasoning rules, which look at how recently the rental was bought or refinanced and how long you have held title. The seasoning section above covers the exact timing, and the specifics are subject to lender guidelines.
Can I borrow against equity in one rental to buy another?
Not in one closing. The line is secured by a rental you already own, it cannot close with a purchase, and the property you are buying cannot be the collateral. Many investors use the line for a later down payment.
What if I owe a lot on the first mortgage?
Then the room under the ceiling is small or zero. A second-lien line needs a first mortgage low enough to leave space under 70% CLTV at a 720 score.
