The Quick Read: It depends on three limits, and the smallest one wins: on a second lien, the line can reach 70% combined loan-to-value at a 720 score or better, minus what you still owe on the first mortgage, and it must also pass the rent test and the second-lien line cap of $500,000. The line sits on a rental you already own and funds the down payment on the next one. Every figure here is a ceiling, subject to underwriting.
- Second lien (you keep a first mortgage): up to 70% CLTV at 720 or better, lines from $50,000 to $500,000.
- First lien (the rental has no mortgage): up to 75% LTV at 740 or better and 70% LTV from 700 to 739 on lines to $500,000. First-lien lines above $500,000, up to $1,000,000, top out at 65% LTV at 720 or better.
- Rent test: gross monthly rent must cover a stress payment on the whole line at 1.10x or better.
- Draw rule: at least 80% of the line is drawn at closing, so size it to the deal. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Key Terms Defined
DSCR (debt service coverage ratio): the rent divided by the loan payment. A higher number means more cushion.
CLTV (combined loan-to-value): every loan secured by the property, added together, divided by its value. On a second lien, that means the first mortgage plus the new line.
Lien: a lender’s legal claim on a property. A second lien sits behind the first mortgage. A first lien stands alone because nothing else is recorded ahead of it.
Draw period: the stretch when you can borrow from the line and pay interest only on what you have drawn.
Seasoning: the waiting time a lender wants between a purchase or refinance and a new loan on the same property.
What Is a DSCR HELOC, Exactly?
A DSCR HELOC is a revolving line of credit secured by a rental you own. It qualifies primarily on the property’s rent covering the payment, subject to lender guidelines. Your personal income is not calculated, and there is no traditional personal-income documentation, W-2s or pay stubs.
The market uses the label loosely. Some lenders apply it to an ordinary investment-property HELOC underwritten on your personal credit and debt load. This one is different. Across the wholesale network Lendmire works with, the structure 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 third lien.
Two more points matter for the next purchase. The collateral must be an investment rental, never your own home or a second home. And the rental can stay in your LLC, subject to program terms, with the members signing as guarantors.
This is a business-purpose loan for non-owner-occupied property, so it is reviewed differently from a standard owner-occupied mortgage. The complete DSCR loans guide covers the broader family of investor loans.
How Much Can You Borrow? The Three-Step Math
The equity limit comes first. Take the property value, multiply by the maximum combined leverage, and subtract every lien already on the property. The CFPB’s HELOC booklet describes the same logic: the lender takes a percentage of the home’s value and subtracts what you owe.
Here is how the program ceilings look, through select programs and subject to underwriting:
| Lien position | Credit score | Leverage ceiling | Line size |
|---|---|---|---|
| Second lien | 720 or better | 70% CLTV | $50,000–$500,000 |
| First lien | 740 or better | 75% LTV | Up to $500,000 |
| First lien | 700–739 | 70% LTV | Up to $500,000 |
| First lien, large line | 720 or better | 65% LTV | Above $500,000 to $1,000,000 |
Leverage is the first limit. The rent test is the second. The program’s dollar cap is the third.
Step one: the equity ceiling
Say you own a rental with a first mortgage equal to 50% of its value and a 735 score. A second lien tops out at 70% CLTV, so the equity ceiling is about 20% of the property’s value. Run it again with a first mortgage at 65% of value. The ceiling drops to roughly 5% of value, which is too thin to fund a meaningful down payment.
A borrower who keeps a first mortgage can only take a second lien, and that product has a 720 floor. A 705 score does not qualify for a second lien at all. A first lien is open to a 700 score only on a rental with no mortgage.
A paid-off rental still hits a ceiling. No mortgage does not mean you can borrow against all of the value.
Step two: the rent test
The rent must cover a stress payment at 1.10x or better. That payment is a fully amortizing payment on the entire credit limit, calculated at the start rate plus 2 percentage points. It covers principal and interest only, not taxes and insurance.
Because the test runs on the whole line, an oversized line can fail it even when the equity math says yes.
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. A two-to-four-unit property may have at most one vacant unit.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. The lender’s own calculation governs.
Step three: the program cap
Lines run from $50,000 to $500,000 on a second lien, and to $1,000,000 on a first lien. An investor may hold at most 5 loans or $2,500,000 with the program. That cap becomes a real limit when you stack lines across several rentals.
Which Limit Binds First?
Equity and the dollar cap are separate limits, and which one binds depends on the property. Equity is the limit when the first mortgage is large relative to value, because combined leverage leaves little room. The dollar cap matters only where value is high and debt is low.
A rental with plenty of equity can still support only a smaller line because the stress payment is computed on the whole commitment. In that case, shrinking the line is the fix. Reaching for a bigger one is not.
The valuation also moves the answer. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, plus a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted. A low value shrinks every number above, since leverage is a percentage of it.
NerdWallet notes that investment-property lines are harder to get than primary-home lines and that fewer lenders offer them. Market surveys, such as this Experian overview, describe broader-market lines that vary widely by lender. The network figures for this program are the ones in the table above: 70% CLTV on a second lien and 75% LTV at most on a first lien. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Does the Line Actually Fund the Next Rental?
The line funds the next purchase’s down payment or closing costs. The purchase itself is a separate loan with its own file.
The two files interact in one place: the purchase lender decides how it treats borrowed funds. Confirm this against the purchase program’s guidelines before you draw. Keep a clean paper trail showing where the money came from and where it went.
Your cash flow matters too. The line’s payment comes out of your pocket on top of the new loan’s payment. The new rental’s rent is tested against its own loan, but the smart test is stricter: can the new rent carry both payments? BiggerPockets’ rookie guide to HELOCs and cash-out refinances makes the same point about passing a test for the added payment.
Because at least 80% of the line is drawn at closing, borrow what the deal needs and no more. The closing draw is never less than $50,000, so on the smallest lines you draw the whole thing. Later draws are at least $5,000 each. A line that is larger than the deal needs means interest on money sitting idle.
What the Line Looks Like After the Down Payment
The draw period is 5 years, interest-only on the drawn balance. Then a 25-year fully amortizing repayment period begins, with a 30-year maturity. The rate is variable, so the payment can move with the balance and with the rate.
Plan for the step-up. When repayment starts, the payment covers principal and interest on whatever you still owe. Many investors aim to pay the balance down during the draw period, using rent, a refinance or a sale. A cash-out refinance on the new property is one common exit.
The CFPB’s HELOC overview also notes that a lender may restrict further advances if the property’s value falls significantly. Your usable line can shrink after approval. And the rental stays pledged: if you fall behind, you risk losing it.
DSCR HELOC vs. the Alternatives
| Option | What happens to the first mortgage | Best fit |
|---|---|---|
| DSCR HELOC | Stays in place | Reaching equity without refinancing |
| DSCR cash-out refinance | Replaced by a new loan | Resetting the whole loan |
| Personal-income investment HELOC | Stays in place | Borrowers with strong documented income |
| Paying cash | Not touched | Buyers with liquid funds |
A DSCR cash-out refinance replaces your first mortgage. If your existing first loan is one you want to keep, the line leaves it alone. A personal-income HELOC reads your income and debt load, so it answers a different question than the rent does.
Stacking Lines Across Rentals
Each rental carries its own line, based on its own equity, rent and credit tier. Say you open a line on rental one and use it to buy rental two, then later open a line on rental two to buy rental three. Each file is tested separately, and every line counts toward the 5-loan or $2,500,000 per-borrower limit.
Using the line cuts your equity. It also leaves less room for a later cash-out or another line on the same property. Think about whether you may want that equity again before you pull it all.
One more exposure point: a declining-market flag lowers the ceiling by 5 points on a given property. A smaller line than the table suggests is a normal result there.
Who This Doesn’t Fit
The program is not offered on:
- An owner-occupied home or second home.
- Rural-designated property, condotels, row homes, leaseholds or land trusts.
- A property listed for sale in the prior 2 months, or one with a solar lien.
- Foreign nationals and ITIN borrowers. Eligible borrowers are US citizens, permanent residents, and non-permanent residents with a Social Security number.
Seasoning matters, too. 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).
Credit history counts as well. The program wants no 30-day late on the mortgage in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves are required.
Geography also limits it. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Short-term rental rules can vary by city, county, HOA and property type, so investors should confirm local rules before relying on projected rental income. A lease in place is required here in any case.
Frequently Asked Questions
How soon after buying a rental can I open a line on it?
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 satisfied. Plan the line before you need the down payment, not the week you find the next deal.
Does a higher credit score always buy more leverage?
No. On a second lien, 720 or better gets the same 70% CLTV ceiling, and there is no cell below 720. On a first lien, 740 or better reaches 75% LTV and 700 to 739 reaches 70%. Score decides which tier you land in, and the equity math decides the rest, subject to underwriting. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Can I use the line without drawing all of it?
Not at closing. At least 80% of the line is drawn at closing, with a $50,000 minimum closing draw, and later draws are at least $5,000. Size the line close to what the down payment and closing costs require, because interest accrues on the drawn balance.
Does my LLC have to come off title?
No. Vesting in your LLC is allowed on investment property, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment. The borrowers on the line need not be the borrowers on the first mortgage.
Will the purchase lender accept the money?
That depends on the purchase program. Check the purchase guidelines before you draw, since a line you cannot use for the deal costs you interest for nothing.
