The Quick Read: A line of credit this large is possible through select programs, but only in one structure: a first lien on a rental that has no mortgage on it. Second-lien lines behind an existing mortgage stop at $500,000, so owners who keep a first mortgage cannot reach this band. The rent qualifies the line, and the coverage test runs on the full credit limit, not on what you draw.
- Structure: a standalone first lien on a paid-off rental, subject to underwriting.
- Leverage: 65% loan-to-value on first-lien lines above $500,000, at a 720 credit score or better.
- Coverage test: at least 1.10x on a stress payment sized on the entire line.
- Valuation: a full interior appraisal, since lines above $400,000 cannot use the automated route.
- Draws: at least 80% of the line is drawn at closing, so a big line means a big drawn balance from the start. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
If you only remember one thing, remember this: the size you want is limited by equity, by the leverage ceiling, and by how much rent the property produces.
What a DSCR HELOC Actually Is
A DSCR HELOC is a revolving line of credit on a rental property, qualified on the rent instead of your personal income. DSCR stands for debt service coverage ratio, which is simply whether the rent covers the debt payment. A HELOC is a home equity line of credit: you get a limit, you borrow against it, and you owe interest on what you have drawn.
The line sits in one of two positions. It is either a standalone second lien behind the first mortgage you keep, or a standalone first lien on a rental with no mortgage. It is never closed together with a purchase, and it is never a third lien. It also cannot be placed on your own home or a second home.
This is the reason people choose it. You reach the equity without refinancing a first mortgage you like, and nobody calculates your personal income. The lender looks at the lease, the rent schedule, your credit report and the valuation. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
The label is loose, though. Some products sold as a DSCR HELOC are really closed-end second loans that pay out one lump sum. Others are rental HELOCs underwritten to personal income and debt ratios. Ask which one you are looking at before you compare anything.
Availability is also thin. NerdWallet notes that a HELOC on an investment property is not offered by all lenders and that qualification requirements are strict. Lenders see higher default risk on rentals than on a primary home. That matches what we see across our wholesale network: very few programs write revolving lines on rentals at all.
Why the $700,000 to $1 Million Band Works Differently
At this size, the lien position is not a choice. Through the select programs we place files with, a second-lien line tops out at $500,000. That is true even at the best credit tier. So a $700,000 line behind an existing mortgage does not exist in this program.
The first-lien structure is the one that reaches $1,000,000. The leverage steps down as the line grows, which is the part people miss.
| Structure | Max leverage | Credit score | Line size |
|---|---|---|---|
| Second lien, behind your mortgage | 70% CLTV | 720+ | Up to $500,000 |
| First lien, lines to $500,000 | 70-75% LTV, by tier | 700+ | Up to $500,000 |
| First lien, lines above $500,000 | 65% LTV | 720+ | To $1,000,000 |
CLTV means combined loan-to-value: the first mortgage balance plus the new line, divided by the property’s value. LTV on a first lien is just the line divided by value, since nothing else sits ahead of it. All of these are ceilings, never offers, and they depend on underwriting.
So the leverage drops to 65% right where you want to go bigger. Bigger lines get less of the property’s value, not more.
How Much Property Value a Line This Size Takes
The short answer: about one and a half times the line, on a rental with no mortgage. That follows from the 65% ceiling on first-lien lines above $500,000. Divide the line by 0.65 and you get the minimum value.
| Your goal | What the property needs |
|---|---|
| A line above $500,000, first lien | Value of roughly 1.5x the line, no mortgage |
| A line to $500,000, first lien, top tier | Value of roughly 1.33x the line |
| A second-lien line, any size to $500,000 | Value where first balance plus line stays within 70% |
Run it for the bottom of your range. A $700,000 line needs a property worth a bit over $1 million with nothing owed on it. A $1 million line needs one worth roughly half again as much as that. Few single rentals clear that bar, which is why most owners asking about this band end up in a different product.
Two ceilings can trim the number further. A declining-market flag lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower. Neither is common, but both show up in real files.
How the Coverage Test Works on the Full Limit
The test divides the property’s gross monthly rent by a qualifying payment. The payment is fully amortizing, runs on the entire credit limit, and is calculated at the start rate plus 2 percentage points. That is a stress payment. It is higher than anything you would actually pay on day one, and it assumes you borrowed every dollar.
The minimum is 1.10x. Rent is the lesser of the appraiser’s market rent on Form 1007 or your actual lease. If the lease is above market, it counts only with three months of receipts. A lease must be in place, and a two-to-four-unit property can have at most one vacant unit.
On a second lien, the lender’s own coverage calculation governs how the first-mortgage payment is treated, so do not assume a formula there.
Here is why size matters so much. Say the rent stays the same and the line doubles. The stress payment roughly doubles, so the coverage number roughly halves. A rental that clears the test at a $500,000 line can fail at $900,000 on identical rent. Taxes, insurance and any HOA dues push the real figure further, because those belong in the denominator too.
What fixes a failing file? Shrink the line until coverage clears 1.10x. Drawing less does not help, because the draw does not change the test. Only a smaller limit, more rent, or a stronger lease does.
Two worked pictures make it concrete, with no dollar figures needed:
- A fourplex with strong rents and a mid-sized line might land comfortably above 1.2x.
- The same fourplex with a line sized to the top of its equity might fall below 1.10x, and the lender would pare the line back.
All qualifying arithmetic here is illustrative, and the lender’s own calculation governs.
How the Line Behaves Over Time
The draw period runs 5 years, interest-only on the drawn balance. Then a 25-year fully amortizing repayment period begins, for a 30-year maturity. The rate is variable through both phases.
At least 80% of the line is drawn at closing, and later draws are at least $5,000 each. On a large line, that rule means a very large balance from day one. You do not get to open a $1 million line and draw $100,000.
Variable rate means your interest cost can move. A CFPB booklet on HELOCs explains that HELOC payments can change as the rate changes. It also warns that the monthly payment can rise sharply once repayment starts, because principal is added to the interest. On a drawn balance this size, that step up deserves a hard look before you sign.
One investor view on BiggerPockets is also worth weighing. In a thread on using a HELOC for investment financing, a poster cautions that a variable-rate line can get more expensive over time and is a poor fit for long-term financing. That is one investor’s opinion, not a rule. It does match how we think about it: a line works well for a defined project with an exit, and badly as permanent funding.
What Gets Reviewed in Place of Income
No traditional personal-income documentation, W-2s, pay stubs or debt-to-income ratio are used. That does not mean the file is thin. Here is what the lender reviews:
- The lease and the rent schedule.
- Your credit report, with a 700 minimum on a first lien and a 720 minimum for the larger lines.
- Mortgage history: no 30-day late in the last 12 months.
- 48 months since any bankruptcy, foreclosure, short sale or deed-in-lieu.
- Insurance, title and the valuation.
No reserves and no cash to close are required. Eligible borrowers are US citizens, permanent residents and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Seasoning has 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).
Appraisal, Title and Entity Ownership
Lines up to $400,000 can use an automated valuation (confidence score 85 or better) with a property inspection report. Anything above that, which includes your whole $700,000 to $1 million band, takes a full interior appraisal on Form 1004, 1073 or 1025. Appraisal waivers are not accepted. A first lien also gets a full title policy.
You can hold the line in an LLC, subject to program terms. The members sign as guarantors. If the title holder is not a borrower, that person signs a non-borrowing owner acknowledgment and the security instrument.
Eligible property includes single-family homes, PUDs, townhomes, two-to-four-unit properties, and warrantable and non-warrantable condominiums. Lots up to 10 acres are fine. The following are outside this lane:
- Rural-designated property, row homes, condotels, leaseholds and land trusts.
- Commercial, agricultural or mixed-use property, and age-restricted communities.
- Hobby farms, modular and log homes, and land contracts.
- A property listed for sale in the prior 2 months, or one with a solar lien.
Portfolio and Exposure Limits
A line is secured by one property. Equity in your other rentals does not pool into it. Each borrower can have at most 5 loans or $2,500,000 with the program. A $1 million line therefore uses up a big share of your room. If you plan to scale across several rentals, count that before you take the largest line on the first one.

Where the General Rule Breaks
Several situations change the answer:
- You still have a first mortgage. The ceiling is $500,000 as a second lien. There is no way to a bigger line behind a mortgage in this program, so a cash-out refinance becomes the realistic path.
- A recent rehab. An automated valuation will not capture added value. At this size you need a full appraisal anyway, but the appraiser still has to find comparable sales that support the new number.
- No tenant yet. A lease in place is required. A vacant property usually fails.
- A rural or odd property type. The excluded list above is strict. A condotel or row home is out, no matter how much equity it holds.
- A product wearing the label. If a quote shows one lump sum, a fixed schedule, or a personal-income test, it is not a rent-qualified revolving line.
Is a Line This Size the Right Tool?
A DSCR HELOC makes sense when you own a rental free and clear, have strong rent relative to the line, and want flexible access to equity without a new first mortgage. It is a reasonable fit for an owner who will deploy most of the line quickly into a defined project and then pay it down.
It is a weaker fit when:
- You have a mortgage you want to keep and need more than $500,000.
- The rent does not cover a stress payment on the full limit.
- You want fixed payments for decades.
- You need a lump sum and do not need revolving access.
In those cases a DSCR cash-out refinance often fits better, because it replaces the first mortgage and sizes the loan on the whole property. If you want to test your own file first, the piece How to Qualify for a DSCR HELOC With a $700,000 to $1 Million Credit Line covers the steps.
Questions to put to any lender before you apply:
1. Is this a revolving line or a closed-end loan?
2. Is the test run on the whole limit, and at what stress?
3. Is the rate variable through repayment?
4. What appraisal and title does a line this size need?
5. What counts toward my per-borrower exposure limit?
Investors sometimes expect a second lien to be the easier route. The investor discussion on BiggerPockets points the same direction: a lender there described multifamily HELOCs as hard to come by, and a home equity loan in second position as the usual alternative. The same pattern shows up in our files.
Key Terms Defined
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value.
LTV (loan-to-value): the loan amount divided by the property’s value; on a first lien it is just the line over value.
Stress payment: a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points, used only to test coverage.
Draw period: the 5 years when you can borrow against the line and pay interest only on what you drew.
Repayment period: the 25 years after the draw period, when you pay principal and interest on the balance.
Seasoning: the waiting time a lender wants after a purchase, refinance or change in title before it will lend.
Frequently Asked Questions
Does the whole credit limit count in the rent test?
Yes. The qualifying payment is sized on the entire limit, not the amount you draw. Drawing less does not help the test. Only a smaller limit, more rent or a stronger lease does, subject to underwriting.
Can my LLC hold the line?
Often, yes. Vesting in your LLC is allowed on investment property, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Can I get a $700,000 line if I still have a mortgage?
Not through this program. A second-lien line behind your mortgage tops out at $500,000. A line from $500,000 to $1,000,000 is a first lien, which means the rental has no mortgage. A cash-out refinance is the usual alternative.
Do I have to draw the whole line?
No, but at least 80% is drawn at closing, and the amount is never less than $50,000. After that, each draw is at least $5,000. The interest-only draw period lasts 5 years.
Is this available everywhere?
No. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is a broker that arranges the line through a wholesale lender, and every file is underwritten individually.
