The Quick Read: Start by confirming the rental has a lease, a first mortgage you plan to keep, at least 6 months on title, and rent that covers a stress payment on the whole credit limit at 1.10x or better. The line sits behind your first mortgage as a standalone second lien, and it qualifies primarily on property-level rental income, subject to lender guidelines.
- The first mortgage stays untouched. The new line is recorded behind it.
- Second-lien leverage tops out at 70% combined loan-to-value (CLTV) with a 720 credit score or better, on lines of $50,000 to $500,000.
- No traditional personal-income documentation, W-2s, pay stubs or debt-to-income ratio. The rent, lease, credit report and valuation are all documented.
- Six-month seasoning clocks, a valuation path and property-type exclusions are where files most often break.
- All figures are ceilings and floors through select programs, subject to underwriting. They are not offers.
Most investors who keep a low-balance first mortgage don’t want to refinance it. A cash-out refinance replaces that loan. A second lien leaves it alone and adds a line behind it. This piece walks through how the file is built, step by step, and where it fails. For the wider background, see Lendmire’s complete DSCR loans guide.
What Is a DSCR HELOC Behind a Kept Mortgage?
A DSCR HELOC is a revolving line of credit on a non-owner-occupied one-to-four-unit rental. It is reviewed on the property’s rent instead of the owner’s personal income. With a mortgage in place, it is written as a standalone second lien. With no mortgage, it is a standalone first lien.
Two points sort out the naming confusion:
- It is a line, not a lump sum. You draw, repay and, within the program’s draw rules, draw again. A closed-end second mortgage pays out once.
- It is never part of a purchase. It is not closed together with a purchase, it is never a third lien, and it is never placed on your own home or a second home.
A HELOC on a property that already carries a mortgage is a second mortgage paid in addition to the first, and the payment varies with the balance (CFPB). Those explainers are written for owner-occupied homes. The investor version differs in how it qualifies.
Key Terms Defined
DSCR (debt-service coverage ratio): Gross monthly rent divided by the qualifying payment. On this line the minimum is 1.10x.
CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property’s value.
Second lien: A loan recorded behind the first mortgage. The first lender gets paid first if the property is sold or foreclosed.
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 pay.
Draw period: The 5-year interest-only stretch when you can draw on the line, followed by a 25-year repayment period.
Seasoning: The time you must have owned or refinanced the property before the line is available.
Who This Fits, and Who Should Look Elsewhere
This line fits a landlord or investor who wants to reach a rental’s equity without refinancing the first mortgage and without opening the personal income file. It suits self-employed owners and multi-property investors whose tax returns don’t show what the rentals earn.
It is a poor fit in these cases:
| Situation | Fit |
|---|---|
| Keeping a first mortgage, 720+ score | Fits as a second lien |
| Keeping a first mortgage, 700–719 score | Below the second-lien floor |
| Rental with no mortgage, 700+ score | Fits as a first lien |
| Rural property, condotel, row home, leasehold | Outside the program |
| Foreign national or ITIN borrower | Not eligible |
| Owner-occupied home or second home | Different product |
Borrowers must be US citizens, permanent residents, or non-permanent residents with a Social Security number.
Note the 700–719 case. A borrower who keeps a first mortgage can only take a second lien, and that tier starts at 720. A first lien exists only on a rental with no mortgage. Those borrowers should look at other structures, such as a cash-out refinance.
The Qualification Gates, in Order
Run the file in this order. Each gate can stop it, so the early ones save you effort on the later ones.
1. Property eligibility. Single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums are eligible, along with lots to 10 acres. 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, a property listed for sale in the prior 2 months, and a property with a solar lien are out. A two-to-four-unit building can have at most 1 vacant unit.
2. Lease and rent. A lease in place is required. Rent is the lesser of the appraisal’s Form 1007 market rent and the lease, unless three months of receipts support a lease above market.
3. Coverage test. Gross monthly rent must be at least 1.10x the qualifying payment. That payment is principal and interest on the full line at the stress rate. Taxes and insurance are not part of it.
4. Equity and combined leverage. CLTV up to 70% at 720 or better on a second lien, lines up to $500,000.
5. Credit and mortgage history. A 720 minimum on a second lien, using the lender’s own credit report. No 30-day late on a mortgage in the last 12 months. 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
6. 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).
7. Valuation and title. See the valuation section below.
8. Vesting. You can hold the rental in an LLC, subject to lender program eligibility. The members sign as guarantors. A title holder who isn’t a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line don’t have to be the borrowers on the first mortgage.
Add the exposure cap: at most 5 loans or $2,500,000 per borrower with the program. Investors with a large portfolio should check this before anything else. There are no reserve or cash-to-close requirements.
Requirements at a Glance
| Requirement | What is reviewed | Where files break |
|---|---|---|
| Coverage | Rent vs. stress payment on full limit | Line sized too big for the rent |
| CLTV | First balance plus line, over value | High first balance leaves little room |
| Credit | Lender’s report, 720+ on a second | Score just under the tier |
| Mortgage history | 12 months, 48 months after a credit event | A recent 30-day late |
| Seasoning | 6 months since last note date and 6 months on title | Recent purchase or refinance |
| Lease | Lease in place, vacancy limit | Expired or missing lease |
| Valuation | Automated valuation or appraisal | Low confidence score |
These are typical ranges through select programs, subject to underwriting. Programs change, and every file is underwritten individually.
How the Coverage Test Works With a First Mortgage in Place
The test runs on the new line alone, sized to its full limit. That is the part that catches people. The lender doesn’t test your drawn balance. It tests a fully amortizing payment on the entire limit at a stressed start rate. An undrawn portion still counts.
Here is a hypothetical, with no dollar figures. Say a rental’s rent covers the stress payment on a smaller credit limit at roughly 1.25x. It clears the 1.10x floor. Raise the limit meaningfully and the same rent falls below 1.10x. The fix is a smaller line, not a different property.
The program terms run the coverage test on the new line alone, so the first-mortgage payment does not join the qualifying payment on a second lien. Confirm on the file how the lender applies that test. The lender’s own coverage calculation governs, and any arithmetic in an article is illustrative.
Rent also matters in how it is measured. If the lease sits well above what the appraiser’s Form 1007 shows for the market, the lease alone won’t carry the file. Three months of rent receipts can support a lease above market.
How Much Line Does Your Equity Support?
Combined leverage is the first mortgage balance plus the new line, divided by value. The ceiling on a second lien is 70% CLTV at 720 or better. A consumer HELOC booklet describes the same logic in plain terms: apply a percentage to the home’s value, then subtract what’s owed (CFPB HELOC booklet).
Run the numbers on a hypothetical rental valued at $500,000 with a first mortgage balance of $250,000. At 70% CLTV, combined debt can reach $350,000, so the new line is capped at $100,000 before coverage is tested. A higher first balance shrinks that room, and a first balance at or above 70% of value leaves none.
Two things trim the ceiling further. A declining-market flag lowers it by 5 points. Philadelphia lines carry a ceiling 10 points lower. Lines start at $50,000 and run to $500,000 on a second lien.
On 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. Later draws are at least $5,000 each. The draw period is 5 years interest-only on the drawn balance, then a 25-year fully amortizing repayment period, with a 30-year maturity. The rate is variable.
Valuation, Title and Documents
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. Lines above $400,000 take a full interior appraisal on Form 1004, 1073 or 1025. Appraisal waivers are not accepted.
Title follows line size. A full title policy goes on a first lien and on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report. Hazard insurance must cover both liens, with flood coverage where required.
A clean file includes:
- The latest first-mortgage statement
- The current lease, plus three months of rent receipts if the lease is above market
- Entity documents if an LLC holds title, and guarantor identification
- Proof of the settlement date and last note date for the seasoning clocks
- Insurance declarations covering both liens
Missing entity papers and an unclear lease are common reasons a file gets pended. Gather both before applying.
Keep the Mortgage or Replace It?
The structure decides this. Compare the options by what happens to the first mortgage.
| Option | First mortgage | Reviewed on |
|---|---|---|
| DSCR HELOC (second lien) | Stays in place | Rental income |
| DSCR cash-out refinance | Replaced | Rental income |
| Bank-style investment HELOC | Stays in place | Personal income and DTI |
A bank-style rental HELOC is hard to find. NerdWallet reports that investment-property HELOCs are offered by fewer lenders with stricter requirements, and that a DSCR second mortgage may be the better route for a property offered mainly as a rental.
Use the second lien when your first mortgage is worth keeping and the line fits under 70% CLTV. Use a cash-out refinance when your first mortgage is not worth keeping, when you need more leverage than a second lien allows, or when the line size doesn’t fit the equity. The cash-out route replaces the first loan, so the old terms are gone.
Why Files Fail and How to Fix Them
Across the wholesale network, the same few problems recur.
| Problem | Cause | Fix |
|---|---|---|
| Coverage under 1.10x | Limit too large for rent | Lower the limit |
| Little or no line available | High first balance | Pay down the first or wait for value |
| Score under 720 | Below the second-lien tier | Rebuild credit and reapply |
| Seasoning shortfall | Recent purchase or refinance | Wait until both clocks pass |
| Ineligible property | Condotel, row home, rural | Consider other structures |
| Automated valuation fails | Score under 85 | Order a full appraisal |
Think of the stress payment as the real gate. Many investors size a line by what they want to draw. The better habit is to size it by what the rent supports, then confirm the equity math.
The practical tip: size the file backward. Start with rent, find the largest limit that clears 1.10x, then check CLTV against that limit. Doing it in the other order produces a line the rent can’t carry.
Frequently Asked Questions
Do I need to keep my current mortgage?
No, but this structure is built for people who do. With a mortgage in place, the line is a second lien behind it. If the property has no mortgage, the same line is written as a first lien instead, with different leverage tiers.
Do I need tax returns or pay stubs?
No. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. There is no traditional personal-income documentation: no W-2s, pay stubs or debt-to-income calculation. The rent, lease, credit report and valuation are all reviewed.
Can my LLC hold title?
Yes, on investment property, subject to program terms. The members sign as guarantors, and a title holder who isn’t a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line need not match the borrowers on the first mortgage.
How long must I 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).
What if my score is just under the tier?
A second lien needs 720. A borrower at 700 to 719 who keeps a first mortgage is below that floor. Improving the score and reapplying is the usual route, or a different structure such as a cash-out refinance.
