The Quick Read: It depends on how much equity the rental holds, because on a second lien the first mortgage balance plus the new line can reach 70% of the property’s value at most, with lines running from $50,000 to $500,000, and the rent must also cover a stress payment on the whole line at 1.10x. The line does not buy the next property. It produces cash for the down payment, and a separate loan buys the rental. Every figure here is a ceiling or floor through select programs, subject to underwriting.
- Second lien (you keep your first mortgage): up to 70% combined loan-to-value at a 720 credit score or better.
- First lien (the rental has no mortgage): up to 75% loan-to-value at 740 or better, or 70% from 700 to 739, on lines up to $500,000.
- Draw rule: at least 80% of the line is drawn at closing, so you cannot open a big line and leave it idle.
- The catch: the purchase lender decides whether borrowed down-payment money counts.
What Is a DSCR HELOC, and What Does It Not Do?
A DSCR HELOC is a revolving line of credit secured by a rental you own. DSCR stands for debt service coverage ratio, which is the rent divided by the payment the lender tests. The rent qualifies the line. Lenders do not use tax returns, W-2s, pay stubs, or a personal debt-to-income ratio, subject to lender guidelines.
The structure is narrow. It is a standalone second lien behind the first mortgage you keep, or a standalone first lien on a rental with no mortgage. It is never closed together with a purchase, and it is never a line on your own home. Subject to program terms, the rental can stay titled in your LLC, with the members signing as guarantors.
Your own-home line is a different, owner-occupied product. A bank line on a rental is hard to find, too. NerdWallet reports that not every lender offers one, requirements are strict, and banks that do lend want at least 20% equity. A second-lien DSCR line tops out at 70% combined leverage, which leaves at least 30% equity behind it.
How Much Can You Borrow? The Three-Step Worksheet
Your line is the lowest of three limits. Work through them in order.
Step 1: the equity limit. Take the property’s value and multiply by the allowed leverage. Then subtract what you owe on the first mortgage. On a second lien, that leverage is a 70% combined loan-to-value (CLTV), which is the first mortgage plus the new line, divided by value. The table shows how much room is left at different first-mortgage balances.
| First mortgage (% of value) | Room at 70% CLTV (% of value) |
|---|---|
| 30% | 40% |
| 40% | 30% |
| 50% | 20% |
| 60% | 10% |
| 65% | 5% |
A sliver of room only works if the property is valuable enough to reach the $50,000 minimum line. A declining-market flag lowers the ceiling by 5 points.
A rental with no mortgage uses first-lien math instead. Loan-to-value (LTV) runs up to 75% at 740 or better, or 70% at 700 to 739, on lines up to $500,000. Lines above $500,000, up to $1,000,000, are capped at 65% LTV at 720 or better. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Step 2: the rent limit. The line must clear a 1.10x coverage ratio. The test payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It covers principal and interest only, not taxes and insurance. 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 must be in place for each rented unit, and a two-to-four-unit building can have at most one vacant unit. Confirm with the lender how a vacant unit’s rent is treated in the coverage calculation.
Because the test runs on the full limit, a bigger line means a bigger test payment. Rent can therefore cap the line even when equity is plentiful. On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. The lender’s own math governs.
Step 3: the program caps. The line cannot exceed $500,000 on a second lien. Per borrower, the program allows at most 5 loans or $2,500,000. Take the lowest of the three limits.
The credit report matters too. A second lien needs a 720 score. A first lien needs 700 for most loans. The program also wants no 30-day mortgage late in the last 12 months and 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu.
Working Backward From the Down Payment
Most investors start with the cash they need, not the equity they have. Here is how to run it in reverse.
Say the next purchase needs a down payment of D. You must draw at least 80% of the line at closing, and the closing draw is never under $50,000. So if the closing draw covers the down payment, the line should be no larger than D divided by 0.80, or you will be forced to draw more than you need. A line smaller than D cannot cover the down payment on its own. Later draws must be at least $5,000 each.
That draw rule changes the plan. Interest-only payments begin on the drawn balance right away, and the draw period lasts 5 years. Then a 25-year repayment period follows, for a 30-year maturity. The rate is variable.
Next, check the new rental. Its rent must also carry its own payment. Then count what remains for closing costs, which sit on top of the down payment.
Key Terms Defined
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value.
Lien position: your place in line for repayment if the property is sold, with a first lien paid before a second lien.
Seasoning: the waiting period a lender wants after a purchase or refinance before it will lend again.
Source of funds: the paper trail showing where your down-payment money came from, which includes borrowed money.
Stress payment: a higher test payment used only to qualify the line, not the payment you actually make.
Two Approvals, Not One
Two separate lenders each decide something here. The line lender reviews the rental that secures the line: its rent, value, your credit, and its seasoning. The purchase lender reviews the new property and your down-payment funds. Neither one overrides the other.
Some lenders accept a documented draw. Others cap the borrowed share or want some of your own cash. The line itself needs no reserves, but the purchase loan may.
The new property is tested on its own rent and its own loan. Your payment on the line still comes out of your cash flow while the new rental ramps up. A down payment that is fully borrowed also means you are financing close to the entire purchase.
For the loan side of the plan, Lendmire’s complete DSCR loans guide covers how the purchase loan is tested.
Which Tool Fits: DSCR HELOC, Cash-Out, or Your Home?
| Factor | DSCR HELOC | DSCR cash-out refinance | Primary-home HELOC |
|---|---|---|---|
| Collateral | Rental you keep | Rental you refinance | Your residence |
| First mortgage | Stays in place | Replaced | Stays in place |
| Reviewed on | Rental’s rent | Rental’s rent | Your income and debts |
| Cash arrives | Draws from a line | One lump sum | Draws from a line |
A DSCR HELOC fits when you want to keep your existing first mortgage and borrow only what you need. A primary-home line is a different, owner-occupied product that puts the roof over your head at risk, so think carefully before using one to buy a rental.
Where the Plan 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).
The property itself. Rural-designated property, row homes, condotels, leaseholds, land trusts, mixed-use, and age-restricted communities are outside this program. So are properties listed for sale in the prior 2 months and properties with a solar lien. Single-family, PUD, two-to-four-unit, and condominium properties are eligible, subject to program terms.
Valuation. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines need a full interior appraisal. Appraisal waivers are not accepted.
Payment growth. The CFPB notes that HELOC payments can change from month to month and often rise when repayment begins. Plan to refinance or pay the line down before that shift. The CFPB’s HELOC booklet also describes the sizing logic: a lender takes a percentage of appraised value, then subtracts what is owed.
Borrower eligibility. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number can apply. Foreign nationals and ITIN borrowers cannot.
Location. Lendmire arranges this line through a wholesale lender in 15 of its 16 licensed states, every licensed state except Tennessee.
Questions to Ask Before You Open the Line
- Does the purchase lender accept a documented HELOC draw, and what share of the down payment can be borrowed?
- Does that lender exclude borrowed funds from reserves?
- How does the line lender treat the first-mortgage payment in its coverage calculation?
- Will the rental clear the 1.10x test on the full limit, not just the amount drawn?
- Does the plan still work if the line’s payment rises?
Frequently Asked Questions
How much of the line do I have to draw at closing?
At least 80%, and the closing draw is never less than $50,000. On the smallest lines, that means the whole line is drawn at closing.
Can the line cover the entire purchase of the next rental?
Not directly. The line is secured by a rental you already own, and a separate loan buys the new property. The purchase lender decides how much borrowed money it will accept toward the down payment.
Does the line payment count against the new rental’s DSCR?
The new rental is tested on its own rent and its own loan. The line’s payment still comes out of your cash flow.
Do I have to wait after buying or refinancing the rental that secures the line?
Yes, in most cases. Seasoning requirements apply to the rental that secures the line, and the details are covered in the Where the Plan Breaks section above.
Can my LLC hold the rental that secures the line?
Yes, on investment property, subject to program terms. The members sign as guarantors, and the borrowers on the line need not match the borrowers on the first mortgage.
