The Quick Read: A DSCR HELOC can sit behind a mortgage you already have on a rental, written as a standalone line qualified on the property’s rent. It is never closed together with a purchase mortgage.
- The line is a second lien behind the first mortgage you keep, or a first lien on a rental with no mortgage.
- Rent qualifies it at a minimum debt-service coverage ratio of 1.10x, measured against a stress payment on the whole line, subject to lender guidelines.
- A second lien reaches up to 70% combined loan-to-value (CLTV), at a 720 score or better, on lines up to $500,000, before any declining-market or Philadelphia reduction.
- Your first mortgage’s note and deed of trust must allow a junior lien.
- It is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
What “At the Same Time” Actually Means
Three different situations hide behind this phrase, and the answers differ.
1. A line behind a mortgage you already own. This is the core case. The line is added as a second lien and the first mortgage stays in place.
2. A line closed together with a purchase mortgage. A piggyback like this is a recognized structure in general, but it is not what this product does.
3. A line on rental one that funds the down payment on rental two. This works because the line is written on its own against a rental you already own, with the purchase of rental two closing separately.
“DSCR HELOC” is a market label, not a standard product. Some lines sold under the name qualify on the owner’s personal income instead. Others replace the first mortgage and become the new first lien. Ask which product a lender is actually describing before you compare numbers.
How the Line Is Built
The line is a revolving second lien on a non-owner-occupied one-to-four-unit rental. The CFPB describes a HELOC generally as an open-end line you can draw on repeatedly, with a draw period followed by a repayment period and usually a variable rate.
Through select programs in Lendmire’s wholesale network, the terms are specific:
- A 5-year interest-only draw period, then a 25-year repayment period, with a 30-year maturity.
- A variable rate.
- At least 80% of the line drawn at closing. Later draws are at least $5,000.
- Lines from $50,000 up to $500,000 on a second lien, which tops out at 70% CLTV. A first lien on a rental with no mortgage reaches 75% LTV at the top tier on lines up to $500,000. Lines can run to $1,000,000, but those above $500,000 are held to a 65% LTV ceiling.
The LLC can hold title, and the members sign as guarantors. The rent qualifies the line: no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines.
How Underwriting Treats the File, Step by Step
Step one: the first mortgage’s documents. The note and deed of trust come first. Check three items: the due-on-sale language, any covenant against additional liens, and the prepayment terms. Get the servicer’s position in writing before a second lien is recorded.
Do not assume that any federal protection against a lender calling a loan due over a junior lien reaches a non-owner-occupied rental. Read your own documents instead of relying on a presumed right.
Step two: combined leverage. CLTV is the first mortgage balance plus the new line, divided by value. A second lien reaches 70% CLTV at a 720 score or better. Below 720 there is no second-lien tier.
Step three: the coverage test. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. That rent is divided by a fully amortizing payment on the entire credit limit at a stress rate, and the result must reach the program’s 1.10x minimum. The qualifying payment is principal and interest only, with no taxes or insurance in it. A lease must be in place, and a two-to-four-unit property may have at most one vacant unit.
Confirm on the file how the lender treats the first-mortgage payment in that calculation. A thin first loan that clears alone can fall below the 1.10x minimum once a second payment is added.
Step four: credit and history. The minimum is 720 on a second lien and 700 on a first lien. No 30-day mortgage late in the last 12 months is allowed. Forty-eight months must pass after a bankruptcy, foreclosure, short sale or deed-in-lieu.
Step five: valuation. Appraisal waivers are not accepted on any line. Lines up to $400,000 need either a full interior appraisal or an automated valuation (confidence score 85 or better) paired with a property inspection report. Larger lines need a full interior appraisal.
Requirements at a Glance
| Item | Second lien | First lien |
|---|---|---|
| Minimum credit score | 720 | 700 |
| Maximum leverage | 70% CLTV | 75% LTV at 740+, 70% at 700-739 |
| Line size | $50,000 to $500,000 | To $500,000, then 65% LTV above to $1,000,000 |
All figures are ceilings and floors through select programs, subject to underwriting.
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). A line on a freshly purchased property therefore cannot be placed.
A Worked Equity Example
Run the numbers on a rental valued at $500,000 with a first mortgage balance equal to 60% of value. At 70% CLTV, only 10% of value is left for the line, and that is the ceiling, not the offer. The $50,000 minimum line would just fit.
Now take the same property with a first mortgage at 68% of value. The room drops to 2% of value. The line cannot be written, however strong the rent is. Equity math is the first filter, so run it before anything else.
Where the General Rule Breaks
- The first mortgage forbids a junior lien. If the note or deed of trust bars one, the line is off the table. A cash-out refinance or a closed-end second may be the workaround.
- Five or more units. The program covers one to four units. The statutory due-on-sale exemption is also written for fewer than five.
- Excluded property. Rural-designated property, condotels, row homes, leaseholds, land trusts, mixed-use and age-restricted communities are outside this lane. So is a property listed for sale in the prior two months.
- Declining markets. A declining-market flag lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
- Exposure limits. Each borrower is capped at 5 loans or $2,500,000 with the program.
- Borrower type. Foreign nationals and ITIN borrowers are not eligible.
- Bank-style lines. A bank-style HELOC generally wants personal or revocable-trust title. Moving a rental out of an LLC to satisfy that can trigger the first mortgage’s due-on-sale clause.
Sequencing: The Order of Events Matters
A second lien added after a DSCR first mortgage puts the first lender’s covenants in play. Reverse the order and a different problem appears. A new first mortgage on a property that already carries a second needs the junior holder to agree to subordinate. An open second lien generally has to be paid off or addressed before the first can be refinanced. Plan the exit before you open the line.
Funding the Next Purchase With a Line on the First
Since the line never closes with a purchase, the practical route is a seasoned draw. Open the line on rental one, let the draw season, and document it as down payment funds on rental two. The purchase lender has to accept the draw as source of funds, so confirm that early. Lendmire’s piece on using a HELOC at the same time as a mortgage on a bank statement file covers a related income-documentation path.
The new loan will also count the line’s payment. Two payments to two servicers can pull coverage on the next file below where you expected.
DSCR HELOC, Cash-Out Refinance and Bank HELOC
| Factor | DSCR HELOC | DSCR cash-out refinance | Bank HELOC |
|---|---|---|---|
| Reviewed on | Rent coverage | Rent coverage | Personal income |
| First mortgage | Stays in place | Replaced | Stays in place |
| Title | LLC allowed | LLC allowed | Often personal only |
| Best fit | Keep a low first | Reset and pull equity | Owner-occupied or second home |
The comparison rows describe each product’s general approach. Lendmire’s own investment property HELOC, qualified on personal income, is a separate product with its own floors and title rules, and its numbers should never be blended with these. For the full picture of how rent-qualified lending works, see the complete DSCR loans guide.
Who This Does Not Fit
- An investor with no rental. A line needs an owned, seasoned property.
- A purchase made in the last six months.
- A borrower whose first mortgage forbids a second lien.
- Anyone who wants a smaller closing draw. At least 80% of the line is drawn at closing.
- An owner who needs a line on a primary home.
Documents to Gather
1. The first mortgage note, deed of trust and a current statement.
2. The signed lease, plus three months of rent receipts if the lease is above market.
3. Entity papers if the property sits in an LLC.
4. A credit report for each guarantor.
5. Hazard insurance covering both liens, with flood coverage where required.
6. The settlement statement showing purchase or refinance dates.
Key Terms Defined
Second lien: a loan secured by the same property that is repaid after the first mortgage if the property is sold in default.
CLTV: the first mortgage balance plus the new line, divided by the property’s value.
Stress payment: the payment used only to test coverage, not the payment you actually make.
Subordination: the junior lender agrees to rank behind a new first loan.
Draw period: the stretch when you can borrow against the line, interest-only on the drawn balance here.
Frequently Asked Questions
Can I put a HELOC on a rental that already has a mortgage?
Yes, as a standalone second lien, if the first mortgage’s documents allow it and the combined leverage fits. Through select programs, a second lien reaches 70% CLTV at a 720 score or better. Underwriting reviews the first mortgage documents, the rent and the valuation.
Does a DSCR HELOC check my personal income?
No. The rental’s rent qualifies the line, with no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines. Credit, mortgage history, the lease and the valuation are still documented.
How does seasoning work?
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 must be met.
Can the line close with my purchase mortgage?
No. It is never closed together with a purchase. The usual route is a seasoned draw from another rental, documented as down payment funds, subject to the purchase lender accepting it.
Can my LLC hold title?
Yes, on investment property, with the members signing as guarantors, subject to underwriting. A bank-style HELOC more often requires personal or trust title.
