The Quick Read: It depends on the equity in the rental you pledge: on a second lien, the line is capped at 70% combined loan-to-value, applied to that rental’s value, minus the first mortgage you keep, and it tops out at $500,000 for a 720 credit score or better, subject to underwriting. The rent on the property you plan to buy does not size the line. The purchase lender sets its own down payment and sourcing rules for the draw. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
- Second lien (you keep a first mortgage): it allows up to 70% CLTV, on lines of $50,000 to $500,000, with a 720 minimum credit score.
- First lien (the rental has no mortgage): it allows up to 75% LTV at 740 or better, and 70% from 700 to 739, on lines to $500,000. Above $500,000, up to $1,000,000, the ceiling is 65% at 720 or better.
- Qualification: the rental’s rent must cover a stress payment on the whole line at 1.10x or better. There is no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines.
- Draw rules: at least 80% of the line is drawn at closing, so you size the line to the purchase.
How Much Can You Borrow on a DSCR HELOC? The Formula
The formula has three steps. Multiply the rental’s value by the combined loan-to-value (CLTV) ceiling. Subtract the first mortgage balance you are keeping. Then check the result against the line-size limits.
CLTV is the first mortgage balance plus the new line, divided by the property’s value. On a second lien, the ceiling is 70% for borrowers at 720 or better, through select programs. Below 720 there is no second-lien tier.
Think of it as room in the property’s value: the 70% ceiling minus the first mortgage’s share of value. If the first mortgage already uses 45% of value, a line equal to about 25% of value fills the 70% ceiling. If the first mortgage uses 65%, only about 5% of value is left. The line must be at least $50,000, so thin room can mean no line at all.
Here is how that plays out at different first-mortgage balances. The figures are percentages of the rental’s value, so you can apply them to your own property.
| First mortgage as % of value | Lien type | Room under the ceiling |
|---|---|---|
| 0% (no mortgage) | First lien | 75% LTV at 740+, 70% at 700-739 |
| 30% | Second lien | About 40% of value |
| 50% | Second lien | About 20% of value |
| 65% | Second lien | About 5% of value |
| 70% or more | None | No room |
Two limits can pull the number down further. A property in a market flagged as declining lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower. The lender’s valuation also drives the result, because the line is sized on the value the lender accepts, not the value you expect.
Paper equity versus usable equity
A rental can look equity-rich on paper and still leave no room. A recent purchase with a small down payment, a prior cash-out refinance or an existing second lien all shrink the space under 70%. A second lien is the structure available when you keep a first mortgage. The line can never sit behind two other liens, so a rental that already carries a second lien has to clear it first.
NerdWallet says investment-property lines come from a smaller pool of lenders, carry stricter requirements than a home line and may call for more than one appraisal. It also notes that lenders generally want you to keep about 20% equity. In this program’s second-lien structure, the cushion is 30% of value at the 70% ceiling.
How Does the Rental Qualify for the Line?
The rent qualifies the line, not your paycheck. A DSCR HELOC qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. There is no traditional personal-income documentation: no W-2s, pay stubs or debt-to-income ratio.
The test is a debt service coverage ratio (DSCR) of at least 1.10x. That is gross monthly rent divided by the qualifying payment. The qualifying payment is a fully amortizing payment on the entire credit limit, at the start rate plus 2 percentage points. It is a stress payment, and it covers principal and interest only, not taxes and insurance.
Because the payment is measured on the whole limit, a $500,000 line is tested as if fully drawn. A bigger line asks more of the rent. 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, and a two-to-four-unit property can have at most 1 vacant unit.
On a second lien, confirm on your file how the lender treats the first-mortgage payment in its coverage calculation before you plan around a specific coverage number.
Credit is checked too. Expect a 720 minimum on a second lien and 700 on a first lien, using the lender’s own credit report. Mortgage history needs no 30-day late in the last 12 months. The program also asks for 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
The property must also fit. Single-family homes, townhomes, planned unit developments, two-to-four-unit buildings and condominiums are eligible. Rural-designated property, condotels, row homes, leaseholds, land trusts and listings from the prior two months are not.
Can the Draw Fund the Next Purchase?
Yes, with a catch on sequencing. The line is a separate loan on rental one. Once you draw it, the cash is yours to use, including for a down payment on another property. But the line is never closed together with a purchase and can never sit on the property you are buying.
So the order runs like this:
1. Confirm the equity in rental one and the first-mortgage balance you are keeping.
2. Ask the purchase lender whether it accepts borrowed funds for the down payment, and what source-of-funds documents it wants.
3. Close the line on rental one and take the draw.
4. Close the purchase loan on the new property, using the drawn cash as documented.
The purchase loan is underwritten on its own. A DSCR purchase loan looks at the new property’s rent against its own payment. A line secured on a different property generally sits outside that ratio. That does not make the line payment free. Your real cash flow still carries it, and the purchase lender decides whether it accepts borrowed funds for the down payment. Ask that question before you draw.
The draw rule shapes your plan
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.
Interest-only payments run on the drawn balance during the 5-year draw period. Then a 25-year repayment period follows, with a 30-year maturity and a variable rate. If you open a large line “just in case,” most of it is borrowed on day one. Size the line to the purchase need, not to the maximum.
Seasoning: the 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). The rental you plan to buy faces the same clocks before it can carry a line of its own.
Key Terms Defined
Lien: a lender’s legal claim on a property. A first lien is paid first; a second lien is paid after it.
Combined loan-to-value (CLTV): all liens on the property added together, divided by its value. This is the figure a second-lien ceiling is measured against.
Draw period: the stretch when you can borrow from the line and pay only interest on the drawn balance. Here it is 5 years.
Stress payment: the payment the lender uses to test coverage. It is higher than your actual starting payment, so it leaves room for the variable rate to move.
Seasoning: the waiting period the lender wants after a purchase or refinance before a new loan on that property.
HELOC, Cash-Out Refinance or Cash: Which Fits?
A DSCR HELOC works best when you like the first mortgage you have and only need a defined chunk of equity. A DSCR cash-out refinance replaces the first mortgage, so it suits investors who would rather reset the whole loan. Cash from savings avoids new debt but ties up capital.
| Option | Fits when | Main tradeoff |
|---|---|---|
| DSCR HELOC (second lien) | You keep your first mortgage | Variable rate, 70% CLTV ceiling |
| DSCR cash-out refinance | You want one new loan | Replaces your existing first mortgage |
| Savings or sale proceeds | You have idle cash | Capital is tied up in one deal |
One more product shares the name. An investment-property HELOC qualified on the borrower’s personal credit and debt ratios follows different rules. Its title and credit requirements differ from the rent-qualified line described here. Make sure any quote you compare names which one it is.
What If You Fall Outside the Box?
Your rental is in an LLC. The line can leave the LLC on title, subject to program terms. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line need not be the borrowers on the first mortgage.
Your credit is between 700 and 719. A second lien needs 720, so a borrower who keeps a first mortgage has no second-lien tier at that score. A first lien reaches down to 700, but it exists only on a rental with no mortgage. A DSCR cash-out refinance is the usual alternative.
You need more than the line allows. Second-lien lines stop at $500,000. A first lien reaches $1,000,000 but at 65% LTV above $500,000. Beyond that, a cash-out refinance is the alternative to price out. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
You want to pledge your own home instead. That is a different, owner-occupied product. This line is never offered on a primary or second home.
You already own several loans with the program. Exposure caps at 5 loans or $2,500,000 per borrower.
You are a foreign national or hold an ITIN. The program is not available. It serves US citizens, permanent residents and non-permanent residents with a Social Security number.
Check eligibility for your state and property type on the file.
What Does a Valuation Look Like?
Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, paired with a property inspection report. A full interior appraisal is the other option. Lines above $400,000 take a full interior appraisal. Appraisal waivers are not accepted.
Title work varies by size. A first lien and any second lien above $400,000 get a full title policy. Smaller second liens use an owner-and-encumbrance report. Hazard insurance must cover both liens, with flood coverage where required. Expect to hand over the first-mortgage statement, the insurance declaration, the vesting deed and the lease.
The Risks Worth Sizing Before You Draw
Borrowing against one rental to buy another stacks leverage. If the draw covers the whole down payment and the new loan covers the rest, you are financed against nearly the full value of the new property. Your two properties now depend on each other’s rent.
Run a stress test before you commit. Ask whether rental one still covers its first mortgage and the line payment if a unit sits vacant for a few months. Ask whether the new property would still hold up if the line’s payment rose. Rate moves matter because the line carries a variable rate.
The collateral risk is real, too. A borrower who falls behind on a line could lose the pledged property. Here, that is the rental you already own, not the one you are buying. The CFPB also notes a lender can stop further draws if the property’s value drops significantly. Because later draws are optional, that risk matters less when you draw most of the line at once.
The 1.10x coverage test is not a profit test. A rental can pass it and still run thin once taxes, insurance and repairs come out. Treat it as the lender’s gate and your own cash-flow math as the real decision.
Skip this route if you need a lump sum you cannot size ahead of time. Skip it if rental one has little equity above its first mortgage. Skip it if you would rather simplify into one new loan. In each case, a cash-out refinance or a smaller purchase may fit better.

Frequently Asked Questions
How long must I own a rental before I can take 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). The rental you buy with the draw faces the same clocks before it can carry a line of its own.
Does the new property’s DSCR affect how much I can borrow?
No. The line is sized on equity in the rental you pledge. The new property’s rent matters to the purchase loan, which is underwritten separately. The lender’s own calculation governs on both loans.
Can I keep the rental in an LLC and still get the line?
Yes, subject to program terms. The property must be an investment property, never an owner-occupied home.
What if I need more than $500,000?
A second lien tops out at $500,000. A first lien on a rental with no mortgage reaches $1,000,000, but lines above $500,000 carry a 65% LTV ceiling at 720 or better. A DSCR cash-out refinance is the usual alternative when you need more. Leverage and pricing vary by lender and program; the final terms follow the full file review.
Will the lender on my next purchase accept the draw as my down payment?
That is the purchase lender’s decision, not the line lender’s. Programs differ on borrowed funds and on how they want the source documented. Confirm the rule with the purchase lender before you draw.
