The Quick Read: Usually less than the program allows, because the limit is the lowest of three numbers: 70% of the rental’s value minus the first mortgage you keep (on a second lien at a 720 credit score or better), the $500,000 line ceiling, and the rent covering a stress payment on the whole line at 1.10x or better.
- A DSCR HELOC is a home equity line on a rental, qualified on the property’s rent instead of your personal income. On a rental that still has a mortgage, the line is a second lien behind that mortgage. It does not retire the mortgage.
- A first-lien line exists only on a rental with no mortgage at all.
- Lines start at $50,000, and at least 80% of the line is drawn at closing. Size the line to what you will actually use.
- The draw period is 5 years of interest-only payments on the drawn balance, followed by a 25-year amortizing repayment period. The rate is variable.
- The safe amount is the one the rent still carries after the payment floats up and after amortization begins. All figures are ceilings and floors, subject to underwriting.
Does a DSCR HELOC Actually Pay Off a Mortgage?
Not directly. A DSCR HELOC (a revolving line secured by a rental, qualified on the rent rather than your paycheck) is written as one of two things. It is a standalone second lien behind a first mortgage you keep, or a standalone first lien on a rental with no mortgage. It is never closed together with a purchase, never a third lien, and never a line on your own home.
So there are three realistic readings of paying off a mortgage:
1. Pay off a loan on the same rental. A second-lien line sits behind the first mortgage, so the first mortgage stays. To replace it, you need a different product, such as a DSCR cash-out refinance. That is a separate program with its own leverage limits.
2. Pay off a mortgage on another property. You draw on the equity in one rental and direct the money toward debt elsewhere. Whether the lender allows a given use of proceeds is a guideline question to confirm before you apply.
3. Use a paid-off rental as the source. A rental with no mortgage can take a first-lien line. This is the cleanest structure, because no other lien competes for the equity.
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. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. You can read the full background in Lendmire’s complete DSCR loans guide.
Key Terms Defined
Combined loan-to-value (CLTV): The first mortgage balance plus the new line, divided by the property’s value. First-lien figures are plain LTV, because no other loan is stacked in front.
Second lien: A loan that sits behind the first mortgage. If the property is sold or foreclosed, the first lien is paid first.
Stress payment: The payment a lender uses to test the deal. Here it is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It is a test, not what you actually pay.
Draw period: The first 5 years, when you pay interest only on what you have drawn.
Repayment period: The 25 years after the draw period, when principal and interest are both due.
DSCR: Gross monthly rent divided by the qualifying payment. At 1.10x, the rent is 10% higher than that payment.
The Sizing Formula: Lowest of Three Numbers
The maximum line is the lowest of equity room, the dollar limits, and the rent test. Equity room is value times the allowed leverage, minus any lien that stays in place. The dollar limits are a $50,000 floor and a $500,000 ceiling on most lines. The rent test is the 1.10x coverage check on the whole line.
Across the wholesale network where Lendmire places these files, the leverage tiers look like this. Each figure is subject to underwriting and applies to a non-owner-occupied one-to-four-unit rental.
| Lien position | Credit score | Maximum leverage |
|---|---|---|
| Second lien, lines to $500,000 | 720 or better | 70% CLTV |
| First lien, lines to $500,000 | 740 or better | 75% LTV |
| First lien, lines to $500,000 | 700 to 739 | 70% LTV |
| First lien, lines above $500,000 to $1,000,000 | 720 or better | 65% LTV |
Below 720, there is no second-lien cell at all. A declining-market flag on the property can lower the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower.
Here is how the equity room works in percentages. Say you hold a 720 score and a rental whose first mortgage equals 45% of its value. At 70% CLTV on a second lien, the room is 25% of value. The $500,000 ceiling and the rent test can still shrink that.
Now say the first mortgage equals 68% of value. The room is 2% of value. On nearly any rental, that sliver falls short of the $50,000 minimum line, so there is no line to write.
If the first mortgage balance sits at or above 70% of value, the room is zero. This is the case where a cash-out refinance, not a line, is the tool that reaches the equity.
How Does the Rent Test Limit the Line?
The rent test caps the line even when the equity is there, because the lender stress-tests the entire credit limit, not just the part you draw. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A lease in place is required, and a two-to-four-unit property may have at most one vacant unit.
The qualifying payment is principal and interest on the full line at the stress rate. Taxes and insurance are not part of it. On a second lien, confirm on the file how the lender treats the first-mortgage payment, because the lender’s own coverage calculation governs.
Here is the catch for payoff plans. An unused portion of the line still counts in the test. If you want to pay off a modest balance, a modest line is the right size.
The test also ignores several real costs. Taxes and insurance sit outside the qualifying payment, and so do repairs, vacancy, management, and capital expenses. A file can pass at 1.10x and still run thin month to month. Passing the test means the lender is satisfied. It does not mean you have cushion.
Maximum, Prudent, Conservative: What Sizing Actually Looks Like
The maximum is what the file can support on paper. The prudent amount leaves room for a variable payment that can rise and for the later switch to amortization. A conservative line is sized so the rent could still carry it with a vacancy or a repair bill.
| Approach | Coverage cushion | What it means for you |
|---|---|---|
| Maximum | Near the 1.10x floor | Little room if the payment floats up |
| Prudent | Clear gap above the floor | Rent carries the line after a rise |
| Conservative | Wide gap above the floor | Survives vacancy plus a rise |
There is no published safe percentage, and anyone who quotes one is guessing. A practical test is to rerun the rent against a payment that is meaningfully higher than today’s. Then rerun it against a payment that includes principal. If coverage still holds on both, the line is sized sensibly. If the deal only works at the interest-only level, you are borrowing against a payment that will change.
The related article on investment property HELOC requirements for paying off a mortgage without overextending covers the broader qualification picture for this kind of plan.
What Happens When the Draw Period Ends?
The payment changes character. For 5 years, you pay interest only on the drawn balance. After that, a 25-year repayment period begins, and the payment includes principal. The loan matures at 30 years.
NerdWallet describes a HELOC as a second mortgage that lets you borrow against your equity, with draw-period payments typically interest-only. That matches the structure here.
The variable rate adds a second moving part. The CFPB’s HELOC booklet notes that on a variable-rate plan, monthly payments may change even if you don’t draw more money. In plain terms, your payment can move with no action on your part, and then move again at the end of the draw period.
Two moves can happen in the same year, and that is the stress case worth modeling.
When Should You Skip the Payoff Plan?
Skip it when you are trading something better than you are getting. Three situations come up.
You like your first mortgage. A HELOC does not replace a first mortgage you keep, but swapping a fixed, amortizing payment for a floating one on another property changes your risk. If the debt you are paying off is fixed and the new debt floats, you have taken on exposure you did not have before.
The payoff would use nearly all your coverage. If the rent only just clears 1.10x on the full line, one vacancy turns a payoff into a cash-flow problem.
You may need to refinance later. Nasdaq notes that a HELOC may limit your ability to refinance your original mortgage, depending on the lender. If a sale or refinance is on your near-term plan, that is worth knowing first.
Here is how the line compares with a cash-out refinance when the goal is to retire debt:
| Factor | DSCR HELOC | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced by the new loan |
| Payment structure | Variable, interest-only for 5 years | Set by that program’s terms |
| Entity | LLC allowed, subject to program terms | Generally closes in an LLC |
| Best fit | Reaching equity behind a loan you keep | Resetting the whole balance |
A cash-out refinance reprices the entire balance, not just the cash you pull, so run both paths side by side.
What Does the File Need?
The file is short on paperwork and strict on collateral. Across the network, the main requirements for a DSCR HELOC, subject to underwriting, are these:
- Credit: 720 minimum on a second lien. On a first lien, the minimum depends on the line size and leverage tier: the 700-to-739 tier applies to lines up to $500,000, and a 740-or-better tier is also offered. No 30-day mortgage late in the last 12 months. At least 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu.
- Documents: the lease, the credit report, and the valuation. No traditional personal-income documentation, W-2s, pay stubs, or personal income calculation. No reserves and no cash to close are required, although your own cushion still matters.
- Valuation: lines 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.
- Entity: the owner’s LLC can hold title, subject to program terms. The members sign as guarantors.
- Exposure: at most 5 loans or $2,500,000 per borrower with the program.
- Borrowers: U.S. citizens, permanent residents, and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Seasoning is the waiting period before you can use the line. 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).
Eligible property includes single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums. Rural-designated property, condotels, row homes, leaseholds, land trusts, mixed-use, and a property listed for sale in the prior 2 months are outside the program.
Lendmire is a broker that arranges these lines through a wholesale lender, and every file is underwritten individually. Nothing here is a commitment to lend.
Red Flags That You Are Overextending
Check yourself against these before you sign:
- The deal clears coverage only on the interest-only payment.
- You are drawing the full available room because it is there.
- The rent barely clears 1.10x, with no cushion for vacancy.
- You are replacing fixed debt with floating debt on a thin-equity property.
- Several rentals carry lines at once, and you have not added up total exposure.
- You would need to sell or refinance within the draw period just to stay whole.
If two or more apply, shrink the line or choose a different structure. Borrowing less than the maximum is not a failure of the plan. It is the plan.
Frequently Asked Questions
Can a DSCR HELOC replace the first mortgage on the same rental?
No. On a rental that still has a mortgage, the line is a standalone second lien behind that mortgage, so the first loan stays. A first-lien line exists only on a rental with no mortgage. If you want the first mortgage gone, a DSCR cash-out refinance is the product that replaces it.
How long do I have to own the rental before I can open a line?
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 clocks must be satisfied before the file can move forward. Underwriting confirms the dates from the closing records.
Can my LLC hold the property?
Yes, 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. The borrowers on the line do not have to be the borrowers on the first mortgage.
Do I have to draw the whole line at closing?
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 must be at least $5,000 each, so the line is not a casual overdraft cushion.
What is the safest amount to borrow?
The amount your rent can carry after the variable payment rises and after the 25-year repayment period starts. Test the coverage at a higher payment and with principal included. If it only works at the interest-only payment, the line is too large.
If you are considering a home equity line on a rental property and want to see how the numbers work, Lendmire can help you compare DSCR HELOC options based on the property, the rent, the equity available, credit profile, combined leverage, and your goals. You can reach the team at 828-256-2183.
The best sizing question is not how much the lender will allow, but how much of your equity you can afford to see tied to a floating payment when the draw period ends.
