The Quick Read: Few big banks write a home equity line on a rental that still carries a mortgage, so the realistic route is a specialty lender that qualifies the line on the property’s rent and places it as a second lien behind your first mortgage. That keeps your existing first loan in place. It also keeps your personal income out of the calculation.
- A DSCR HELOC on a mortgaged rental is a standalone second lien. It is never a third lien, and it is never closed together with a purchase.
- The rent qualifies the line. The program minimum is a 1.10x coverage ratio on a stress payment across the whole credit limit, subject to underwriting.
- Second-lien leverage tops out at 70% combined loan-to-value at a 720 credit score or better, on lines of $50,000 to $500,000.
- Most of the line is funded at closing, and the later draws come in pieces of $5,000 or more.
- Lendmire is a broker. It matches your rental to wholesale lenders that write this product in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Which Banks Offer a DSCR HELOC on a Mortgaged Rental?
This article does not rank banks. The answer depends on the lender type and on your file, and a ranked list would go stale as lenders change their programs.
Here is the practical picture. NerdWallet reports that investment-property HELOCs exist but that fewer lenders offer them. It also says you can borrow less than you could against a primary home, and some lenders ask for more than one appraisal. One investor on the BiggerPockets Rookie Reply podcast called local and national banks and found none that would write a HELOC on a rental that still had a mortgage. That is one story, not a statistic. It matches what the lender types below tend to do.
| Lender type | What it underwrites | Usual obstacle |
|---|---|---|
| Big retail banks | Your income and debts | Many decline rental collateral |
| Community banks, credit unions | Your income, local ties | Own limits on rentals and location |
| Non-bank wholesale lenders | The rent and the equity | Narrow property and lien rules |
A broker sits on the third row. Lendmire works with a network of wholesale DSCR HELOC lenders and matches the scenario to the program, so you are not calling banks one by one. Which lenders can write your file depends on your property type, credit profile, leverage need, and state.
What a DSCR HELOC Actually Is
A DSCR HELOC is a revolving line of credit secured by a non-owner-occupied rental of one to four units. DSCR stands for debt service coverage ratio, which is the rent divided by the payment the lender tests. The line qualifies primarily on property-level rental income covering that payment, subject to lender guidelines. No traditional personal-income documentation, W-2s, pay stubs, or debt-to-income ratio enter the calculation.
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.
Two lien positions exist. On a rental with a first mortgage, the line is a standalone second lien. On a rental with no mortgage, it is a standalone first lien. Both are variable-rate lines.
The line is never offered on your own home or a second home. A HELOC on your primary residence is a different, owner-occupied product.
You can hold the rental in your LLC, subject to program terms. The LLC members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line do not need to be the borrowers on the first mortgage.
Key Terms Defined
Second lien: a loan that sits behind your first mortgage. If the property were sold or foreclosed, the first lien is paid first.
Combined loan-to-value (CLTV): your first mortgage balance plus the new line, divided by the property’s value. First-lien lines use plain loan-to-value (LTV) because no other mortgage exists.
Draw period: the stretch when you can borrow from the line and pay interest only on what you have drawn.
Repayment period: the stretch after the draw period when you pay the balance down on a fixed schedule and can no longer borrow.
Seasoning: the waiting period between buying or refinancing a property and taking a new loan against it.
Stress payment: the payment the lender uses to test the rent, built with a cushion so the rental has margin if the variable rate rises.
How Underwriting Treats a Mortgaged Rental, Step by Step
A lender works through the file in a set order. Knowing the order tells you where a file can stall.
1. Eligibility screen. The property must be a non-owner-occupied one-to-four-unit rental with a lease in place. A two-to-four-unit building may have at most one vacant unit. Eligible types include single-family homes, PUDs, townhomes, two-to-four-unit buildings, and warrantable and non-warrantable condominiums, plus lots up to 10 acres.
2. Equity math. The largest line is the property’s value times the CLTV cap, minus what you owe on the first mortgage. The CFPB’s HELOC booklet shows the same idea in its example. The credit limit is a percentage of the home’s value, less the mortgage balance. On this program the cap for a second lien is 70% CLTV at a 720 score or better, and the line must be at least $50,000.
3. Valuation. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, paired with a property inspection report. A full interior appraisal is also accepted at that size. Lines above $400,000 need a full interior appraisal on Form 1004, 1073, or 1025. Appraisal waivers are not accepted.
4. The coverage test. The lender divides gross monthly rent by a qualifying payment. That payment is principal and interest on the entire credit limit, fully amortizing, with a stress cushion built in. Taxes and insurance are not part of it. The minimum is 1.10x.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The lender’s own calculation governs.
5. First-mortgage check. Your first loan has to coexist with a junior lien. Review the first-mortgage documents, and ask the broker whether the lender you are considering will sit behind your type of first loan. Some second-lien lenders will not sit behind a non-QM first mortgage, so the kind of first loan you hold can decide the file.
6. Documents. Expect the lease or rent schedule, the first-mortgage statement, hazard insurance covering both liens, flood coverage where required, and the vesting and title documents. The lender also reviews your credit report and the valuation. Because the rent qualifies the line, tax returns, W-2s, and pay stubs are not part of the file. One investor in a BiggerPockets thread said underwriting kept requesting additional documents.
7. Closing and draws. 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. After that, each draw is at least $5,000. The rate and the pricing terms come with the lender’s disclosures.
A Worked Example With Percentages and Ratios
These inputs are modeled assumptions, not market data.
Say a rental has a first mortgage equal to 45% of its appraised value, and the owner holds a 735 credit score. The second-lien cap is 70% CLTV. That leaves room for a line worth up to 25% of the property’s value, before the $50,000 minimum and $500,000 ceiling apply. Whether 25% of your value clears $50,000 depends on what the property appraises for. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Now the coverage test. The stress payment is calculated on the full limit, even though you may not use all of it later. Suppose the lender’s calculation lands at 1.15x. That clears the 1.10x minimum.
Suppose it lands at 1.05x instead. The file falls short at that line size. A smaller line lowers the tested payment, so reducing the limit is one adjustment to try. Rent supported by a lease above market and three months of receipts is another path. A lender then decides, subject to credit approval and property review.
Structures and Variations
The tiers differ by lien position, and the leverage tiers govern every property type, condominiums included.
| Position | Credit score | Max leverage | Line size |
|---|---|---|---|
| Second lien (mortgaged rental) | 720+ | 70% CLTV | $50,000–$500,000 |
| First lien (no mortgage) | 740+ | 75% LTV | To $500,000 |
| First lien (no mortgage) | 700–739 | 70% LTV | To $500,000 |
| First lien (no mortgage) | 720+ | 65% LTV | $500,000–$1,000,000 |
These are ceilings, not offers, and each file is underwritten individually. Below 720, a second-lien line is not available. A first lien exists only on a rental with no mortgage at all.
A declining-market flag can lower the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
Every line carries the same structure. The draw period is five years, interest only on the drawn balance. A 25-year fully amortizing repayment period follows, for a 30-year maturity.
On credit history, the mortgage record must show no 30-day late in the last 12 months. Forty-eight months must have passed since any bankruptcy, foreclosure, short sale, or deed-in-lieu. No reserves and no cash to close are required. One borrower can have at most five loans or $2,500,000 with the program.
Where the General Rule Breaks
LLC title. Many bank lines want the loan in your personal name. This program allows an LLC on title for investment property, subject to program terms. Land trusts are not eligible, and a property held in one needs a different structure.
A rental with no mortgage. It can take a first-lien line with its own tiers, shown above. A borrower who keeps a first mortgage can only take a second lien.
Closed-end seconds sold as HELOCs. Some products labeled DSCR HELOCs are really closed-end seconds that pay out one fixed amount. Confirm the product is a revolving line before you compare pricing or terms.
Borrower status. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
Property types outside the program. These are rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, age-restricted communities, hobby farms, modular and log homes, land contracts, and mixed-use. A property listed for sale in the prior two months is out, as is one with a solar lien.
A primary-home line used on a rental. That is the owner-occupied product, and it is not what this article covers. Its terms may restrict renting out the home.
Location. The program is offered in Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia, and Washington.
Seasoning: Two Clocks, One Rule
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). If you just closed on a rental, see Lendmire’s guide Banks That Offer an Investment Property HELOC on a Rental You Just Bought.
HELOC, Cash-Out Refinance, or Bank Line?
| Factor | DSCR HELOC | DSCR cash-out refi | Bank HELOC |
|---|---|---|---|
| First mortgage | Stays in place | Replaced | Stays in place |
| Reviewed on | The rent | The rent | Your income and debts |
| Funds | Revolving line | One lump sum | Revolving line |
| Best fit | Keep the first loan | Reset the whole loan | Strong personal income |
A bank HELOC typically weighs your personal income and debt-to-income ratio. A DSCR line weighs the rental. If your first mortgage is worth keeping, a second-lien line avoids resetting it.
What the Decision Looks Like in Practice
Start with the property, not the lender. A few questions sort most situations.
| Your situation | Likely path |
|---|---|
| First mortgage in place, 720+ credit | Second-lien DSCR line |
| Rental owned free and clear | First-lien DSCR line |
| Credit 700–719 with a first mortgage | A different structure, such as a cash-out refinance |
| Rental held in a land trust | Needs a vesting change or another structure |
| Strong personal income, bank relationship | Ask the bank, then compare |
Timing matters if the line will fund your next purchase. The line has to exist before you go under contract. The new purchase loan is then judged mostly on the new property’s own rent, not on the line’s payment.
Know the risks before you sign. A HELOC is an open-end line with a draw period followed by a repayment period, and the CFPB warns you could lose the property if you cannot repay. The rate is variable, so your payment can change. You also pay the line off when you sell the rental.
Before you apply, gather the lease, the first-mortgage statement, your insurance declarations, and the title or vesting documents. Run the coverage test on the full limit, not only the amount you plan to draw.
Frequently Asked Questions
Do I need a particular type of first mortgage?
Your first mortgage has to allow a junior lien, and the lender has to be willing to sit behind that loan type. Some second-lien lenders will not sit behind a non-QM first. Send the first-mortgage statement early so the broker can screen for this before you spend on a valuation.
How does the DSCR test work on a second lien?
The lender divides gross monthly rent by a qualifying payment on the entire credit limit, and the program minimum is 1.10x. Taxes and insurance are not in that payment. Confirm on your file how the lender treats the first-mortgage payment, because the lender’s own calculation governs.
How soon after buying or refinancing can I apply?
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 rental that has cleared both can be reviewed, subject to underwriting.
Do I need tax returns, reserves, or cash to close?
No traditional personal-income documentation, W-2s, or pay stubs are needed, because the line qualifies primarily on the rent covering the payment, subject to lender guidelines. The lease, credit report, and valuation are all documented.
What if my credit is below 720?
With a mortgage on the rental, a second lien needs 720. If the rental has no mortgage, a first-lien line is possible from 700. Otherwise, a different structure such as a cash-out refinance is the usual alternative. Which lenders write your file depends on the property, credit profile, and leverage you need.
