The Quick Read: A DSCR HELOC leaves your first mortgage alone because it is a separate second lien (or a standalone first lien on a paid-off rental). Your existing balance, maturity and amortization schedule keep running. The new line carries its own clock, and the rental’s income, not yours, qualifies it, subject to lender guidelines.
- A second lien reaches up to 70% combined loan-to-value (CLTV) at a 720 credit score or better, on lines from $50,000 to $500,000, through select programs.
- The line has its own timeline: 5 years interest-only, then 25 years of repayment, with a 30-year maturity and a variable rate.
- Coverage is tested at a minimum DSCR of 1.10x on a stress payment over the whole line, not just the drawn amount.
- The program is offered 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.
The best program for your situation depends on the first mortgage you keep, the rent, the equity, and your credit. Lendmire is a mortgage broker. It shops a network of wholesale lenders and matches the scenario to a program. Lenders review and approve every file individually.
What Does “Without Restarting Your Mortgage Term” Actually Mean?
Your first mortgage has a clock. It has a balance, a maturity date and an amortization schedule. A cash-out refinance replaces that loan, so the clock starts over with a new balance and a new term. A home equity line does not touch it.
Think of two separate loans on one property. The first keeps its balance, maturity and schedule. The second is a new lien with its own draw period and repayment period. Nothing is re-amortized on the first loan.
The Consumer Financial Protection Bureau defines equity as the property’s value minus what you owe on the mortgage, and describes a HELOC as an open-end line you can borrow against repeatedly. That equity is what a DSCR HELOC taps. A BiggerPockets explainer makes the same structural point: a HELOC leaves the original mortgage in place and adds a second mortgage behind it.
“Without restarting” does not mean “without any new term.” The first mortgage is preserved. The line has its own calendar. Keep that distinction in mind, because the end of the draw period is where the real risk sits.
Key Terms Defined
DSCR (debt service coverage ratio): The rental’s monthly rent divided by the qualifying payment. It measures whether the property’s income covers its debt.
Second lien: A loan recorded behind your first mortgage. If the property were sold or foreclosed, the first lien is paid first.
CLTV (combined loan-to-value): Your first mortgage balance plus the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line. On this program it is 5 years, interest-only on the drawn balance.
Repayment period: The stretch after the draw period, when the balance amortizes. On this program it is 25 years.
Seasoning: The waiting period between buying or refinancing a property and applying for new financing on it.
How Does Underwriting Treat a DSCR HELOC, Step by Step?
Underwriting follows the property, not your paycheck. The file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines: no traditional personal-income documentation, W-2s or personal income calculation. Here is how a file moves.
1. The first lien is identified. Its balance and terms set how much room is left for a second loan behind it. A second lender must be comfortable sitting in that position.
2. Equity is measured. The lender takes the property’s value and subtracts every existing lien. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
3. CLTV is set. On a second lien, the first balance plus the new line cannot exceed 70% of value, at a 720 score or better. This is the binding limit on how much you can borrow.
4. Coverage is tested. Gross monthly rent is divided by a qualifying payment. That payment is fully amortizing on the entire credit limit, at the start rate plus 2 percentage points. The minimum is 1.10x.
5. Credit and history are checked. A second lien needs a 720 score. A first lien needs 700. The program wants no 30-day mortgage late in the last 12 months and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
6. Title and vesting are cleared. The rental can sit in your LLC, subject to program terms. The members sign as guarantors.
7. The line is set up. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each.
Whether the first-mortgage payment joins the qualifying payment on a second lien is not published. The lender’s own coverage calculation governs. Plan on the combined obligation mattering, and size the line to the rent, not only to the equity.
The rent counts at the lesser of the appraiser’s market rent (Form 1007) or the lease. A lease must be in place. A two-to-four-unit property can have at most one vacant unit.
What Structures and Variations Exist?
There are four shapes worth knowing. Only some of them leave your first mortgage alone.
| Structure | Effect on first mortgage | Qualified on |
|---|---|---|
| DSCR HELOC, second lien | Stays in place, untouched | Rent |
| DSCR HELOC, first lien | None exists (paid-off rental) | Rent |
| DSCR cash-out refinance | Replaced, term restarts | Rent |
| Bank HELOC on a rental | Stays in place | Personal income and DTI |
The second-lien line. This is the core “no restart” product. It sits behind the first mortgage you keep, up to 70% CLTV, lines $50,000 to $500,000.
The first-lien line. This fits a rental with no mortgage. Leverage reaches 75% LTV at 740 or better, and 70% from 700 to 739, on lines to $500,000. Lines above $500,000, up to $1,000,000, are capped at 65% LTV. A first lien is a standalone loan, so there is no first mortgage to preserve. Every figure here varies by lender and program: guidelines, property type, leverage, and credit profile all apply.
The closed-end second. Some lenders offer a lump-sum second with a fixed schedule instead of a revolving line. It avoids the end-of-draw payment change. It is a different product, so ask which one you are being offered.
Bank HELOCs on rentals. These are underwritten on your personal credit, income and DTI, not rent. Many banks only write lines on a primary home. BiggerPockets members describe regional banks and credit unions as the usual source for rental lines. The network figure here is 70% CLTV on a second lien, qualified on rent.
One warning on labels. Some products sold as a “DSCR HELOC” pay off the first mortgage and become the new first lien. That is a refinance wearing a different name. Check the closing figures: if your first mortgage is being paid off, your term restarted.
How to Tell a Real “No Restart” Product From a Refinance
Run this short check before you apply.
- Does it pay off my first mortgage? If yes, it is a refinance.
- What lien position does it take? A second lien behind your loan keeps your term intact.
- Does the closing statement show a payoff to my current servicer? If it does, your term restarted.
- Who gets tested? If the lender asks for pay stubs and DTI, it is not a rent-qualified product.
- Does my first mortgage allow a junior lien? Some first mortgages restrict one. Read yours, or ask your servicer.
Do not retitle the property to fit a program without asking first. A transfer of title can trigger a due-on-sale clause on the first mortgage. The borrowers on the line need not be the same as the borrowers on the first mortgage, and a title holder who is not a borrower signs an acknowledgment and the security instrument.
What Does the Draw and Repayment Calendar Look Like?
The first mortgage keeps its schedule. The line runs its own. For five years you pay interest only on what you have drawn. Then a 25-year fully amortizing repayment period begins, and the 30-year maturity closes it out.
The payment step-up at the start of repayment is the real shock. The CFPB warns that payments after the draw period are often significantly higher. The rate here is variable, so the payment can also move with the market. Plan for both.
Say you keep a low first mortgage and draw most of a line to buy another rental. During the draw period you carry interest only on the line. When repayment starts, principal joins the bill. If the rent barely cleared 1.10x at the start, that step-up can squeeze your cash flow. Many investors plan a refinance, a sale or a paydown before the five years end. That is a plan, not a promise, so build in margin.
The CFPB’s HELOC brochure also notes that some plans require an initial draw or minimum draw amounts. This program does, at 80% of the line at closing and $5,000 per later draw. Do not size the line larger than you plan to use.
A Worked Comparison: Keep-the-First Versus Cash-Out
Run the logic on a single rental. These figures are ratios and percentages only, and the lender’s calculation governs.
Picture a fourplex with a low-cost first mortgage at roughly 45% of value. You want cash for another purchase. Leaving the first loan alone and adding a line to 70% CLTV gives you about 25 points of value in available equity, subject to underwriting.
A cash-out refinance on the same property could be sized differently, but it replaces the whole first balance. You pay off a loan you liked, and the new loan starts a new amortization clock at the beginning, where the early payments are mostly interest.
Now the coverage side. Say the rent covers the old first-mortgage payment at about 1.7x. Adding a second payment can pull combined coverage toward the low 1.1x range, though the lender’s own calculation governs. The line may be limited by coverage well before it is limited by equity.
The second-lien cost is usually higher than the first-lien cost. So the question is the blended cost: a low first loan plus a higher line on the new money, versus one new loan on everything. When your existing first mortgage is cheaper than anything available now, keeping it tends to win. When it is not, the refinance can win. The rate and the pricing terms come with the lender’s disclosures.
Where the General Rule Breaks
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).
Properties that are out. Rural-designated property, row homes, condotels, leaseholds, land trusts, mixed-use, commercial or agricultural property, and properties listed for sale in the prior 2 months are outside the program. So is any property with a solar lien. Warrantable and non-warrantable condominiums are eligible property types. A declining-market flag can lower the ceiling by 5 points.
Borrowers. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
Exposure limits. The program allows at most 5 loans or $2,500,000 per borrower.
Not your own home. This line is never offered on an owner-occupied home or second home. It is also never closed together with a purchase, and never a third lien. A primary-residence HELOC is a different product, qualified on personal income, and it is a consumer loan. Some investors open one while a property is still their residence. That is a separate strategy with its own rules.
Your first mortgage. Some first mortgages restrict junior liens. If yours does, the second lien cannot be placed no matter how strong the rent is. Verify this first.
Business purpose. 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.
When a Cash-Out Refinance Is the Better Move
Be honest about when this is not the right tool. Consider a cash-out refinance when:
- Your existing first mortgage has terms you would happily replace.
- You need more cash than a second lien allows. A second lien stops at 70% CLTV and $500,000.
- Coverage fails once a second payment is added, but a single refinanced payment would clear.
- Your property type or credit tier fits a refinance but not the line.
- You want one loan and one payment.
A refinance resets your term, and it may carry costs on the old loan. Check your existing loan for a prepayment penalty before you decide. Pull up the whole picture: remaining balance, remaining years, and what the new money would cost.
How Do You Judge the Best Program for Your Situation?
The best program depends entirely on your property, your credit and your goals. A broker that shops several wholesale lenders can match your file to the right guidelines. Use this checklist when you compare options:
| Question | Why it matters |
|---|---|
| Lien position | Second lien keeps your first loan intact |
| Rent test | Rent versus personal income and DTI |
| Entity title | Whether your LLC can stay on title |
| Property type | Rural, row homes and condotels are out |
| Leverage fit | CLTV limit versus the cash you need |
| Draw structure | Draw period, repayment period, minimum draws |
| First-loan fit | Whether your first mortgage allows a junior lien |
Across our wholesale network, the strictest overlays tend to show up on property type, valuation and first-lien restrictions. Coverage math on a line is also unusual. The lender tests the stress payment on the entire limit, not just the drawn balance. So a line you plan to draw only in part still has to clear 1.10x as if fully drawn.
How Do You Prepare?
1. Pull your first mortgage’s balance, maturity and any junior-lien language. 2. Gather your leases and a rent roll. A lease in place is required. 3. Check how long you have held the property and when it was last bought or refinanced. 4. Estimate coverage against the whole line, not the part you plan to draw. 5. Check your credit tier: 720 for a second lien, 700 for a first lien. 6. Decide the line size you can live with after the step-up.
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.
Frequently Asked Questions
Does a DSCR HELOC change my first mortgage?
No. The first mortgage keeps its balance, rate, maturity and schedule. The line is a separate lien, and the lender’s own coverage calculation governs how the payments are tested together. Check that your first mortgage allows a junior lien.
Is a DSCR HELOC a refinance?
No. A refinance replaces the first loan and restarts its term. A second-lien line adds a new loan behind it. Be careful with product labels, because some products sold as a HELOC pay off the first mortgage.
Can my LLC hold the property?
Yes, in many cases. Vesting in the owner’s LLC is allowed for investment property, with the members signing as guarantors, per lender program requirements.
Does a paid-off rental qualify?
Yes, as a standalone first lien. Leverage reaches 75% LTV at 740 or better, on lines up to $500,000. Lines above $500,000 are limited to 65% LTV. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
