The Quick Read: On a rental with a first mortgage you plan to keep, a DSCR HELOC typically reaches up to 70% combined loan-to-value (CLTV) on a second lien, on lines from $50,000 to $500,000, subject to underwriting. You take the lesser of two limits: the equity left after your first mortgage balance, or the amount the rent can support at a 1.10x coverage test, unless three months of rent receipts support a lease above market.
- Room on the line equals value times 70%, minus the first mortgage balance.
- The full line counts toward CLTV, not just the amount drawn.
- A second lien needs a 720 credit score or better.
- The rent qualifies the line, and an LLC can stay on title, depending on program terms.
- A rental with no mortgage can take a first-lien line instead. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Your first mortgage stays exactly as it is. The line sits behind it as a standalone second lien. Nothing gets refinanced, so a low first stays low.
What Does “DSCR HELOC” Mean Here?
The term gets used two ways in the market. Some products called a HELOC on a rental are judged on the owner’s credit, income, and personal debt. This article uses the other meaning: a revolving line on a one-to-four-unit rental, qualified primarily on property-level rental income, subject to lender guidelines. The owner’s income is never calculated. No traditional personal-income documentation, W-2s, or pay stubs.
If you have seen a bank HELOC on a rental, this is a different file. Different qualification test, different documents, different sizing limits. Brokers who place both see the mix-up constantly, and it changes the answer to “how much.”
Key Terms Defined
DSCR: Debt service coverage ratio. Gross monthly rent divided by the qualifying payment.
CLTV: Combined loan-to-value. The first mortgage balance plus the full new line, divided by the property’s value.
Second lien: A loan recorded behind the first mortgage. The first gets paid first if the property is sold or foreclosed.
Draw period: The stretch when you can borrow against the line and pay interest on the drawn balance. This program runs 5 years interest-only, then a 25-year repayment period, for a 30-year maturity.
How Much Can You Borrow?
The formula is short: property value times 70%, minus your first mortgage balance, capped at $500,000. Whatever that leaves is the room for a line. On a second lien, the 70% ceiling applies at a 720 credit score or better. Below 720 there is no second-lien tier. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Run the numbers on three rentals, each valued at 100 units for simplicity. Express the first mortgage as a share of value and the room falls out:
| First mortgage as share of value | Room under 70% CLTV | Line possible? |
|---|---|---|
| 40% | 30% of value | Yes, if rent covers it |
| 55% | 15% of value | Yes, a smaller line |
| 68% | 2% of value | Too thin to reach the $50,000 minimum on most rentals |
So a $400,000 rental with a first at 55% of value leaves room for roughly 15% of value, about $60,000. That is simple arithmetic from the ceiling, illustrative only, and the lender’s own calculation governs. It also shows why the dollar cap rarely binds. On most rentals the equity test limits the line long before $500,000 does.
One detail catches people. CLTV counts the entire approved limit, not the drawn balance. Apply for a larger line and leave part undrawn, and the full limit still sits in the equity test. Here the draw rule matters too: 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 are at least $5,000 each.
Credit score does not buy extra second-lien leverage. At 720 or better, the ceiling is 70% CLTV. A higher score does not move it.
The Second Limit: Rent Coverage
Equity is only half the test. The rent has to cover a stress payment on the entire line, and that can pull the line below the equity number.
The coverage test works like this. Gross monthly rent is divided by a qualifying payment. That payment is fully amortizing principal and interest on the whole credit limit at the start rate plus 2 percentage points. It is a stress payment, built to be larger than what you will actually owe during the interest-only draw period. Taxes and insurance are not part of the qualifying payment. The minimum is 1.10x.
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 can have at most one vacant unit.
Does the first mortgage payment join the qualifying payment on a second lien? That is not published. Confirm on the file how the lender treats it. Do not assume either way when you size the line. The coverage calculation the lender runs is the one that counts.
Picture an investor with a duplex valued well above the first mortgage balance, so equity room is generous. The rent is modest, and a stress payment on a large line pushes coverage under 1.10x. The line shrinks to the size where rent clears the test. Equity said yes. Rent said smaller. The lower number wins.
Will Your First Mortgage Allow a Second Lien?
Check this before anything else. Many first mortgages are silent on junior liens. Some restrict them, and DSCR first mortgages are not exempt. Read the note and the security instrument, or ask the servicer in writing.
A checklist for the first loan:
- Does the loan documentation permit a subordinate lien on the property?
- Is the balance on your statement current, and does the CLTV test hold with the full new line added?
- Does anyone else hold a lien, such as a solar lien? A property with a solar lien is not eligible.
- Is hazard insurance in place for both liens, with flood coverage where required?
The borrowers on the new line do not have to be the borrowers on the first mortgage. Title is flexible too. Vesting in the owner’s LLC is allowed on an 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 and the security instrument.
First Lien: When the Rental Has No Mortgage
A paid-off rental can take a first-lien line instead. This is a different leverage table, and it only applies when the property has no mortgage. Not “nearly paid off.” None.
| Lien position | Credit score | Maximum leverage | Line size |
|---|---|---|---|
| Second lien | 720+ | 70% CLTV | $50,000 to $500,000 |
| First lien | 740+ | 75% LTV | To $500,000 |
| First lien | 700 to 739 | 70% LTV | To $500,000 |
| First lien | 720+ | 65% LTV | Above $500,000 to $1,000,000 |
The first-lien floor is 700. On lines above $500,000, the ceiling is 65%, so a larger line does not mean a larger percentage. A borrower with a first mortgage cannot use this table. Keep the first and you take a second lien, with the 720 floor.
Valuation, Seasoning, and Eligibility
Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, paired with a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal. Appraisal waivers are not accepted.
Recent rehab complicates the automated route. An automated model may not capture fresh improvements, as one investor on BiggerPockets notes about a recently rehabbed property. If the value depends on work you just finished, plan on the full appraisal, and the appraiser’s comps will carry the number.
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).
Other file points, all subject to underwriting:
- No reserves and no cash to close are required.
- No 30-day mortgage late in the last 12 months. 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu.
- At most 5 loans or $2,500,000 per borrower with the program.
- Eligible: single-family, PUD, townhome, two-to-four units, and warrantable or non-warrantable condominiums, plus lots to 10 acres.
- Not eligible: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, modular and log homes, mixed-use, and a property listed for sale in the prior 2 months.
- A declining-market flag lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
- US citizens, permanent residents, and non-permanent residents with a Social Security number qualify. Foreign nationals and ITIN borrowers do not.

Keep the First or Refinance Everything?
Keep the first when it is cheap and the equity room is enough for the job. A line behind it adds one new obligation and leaves the existing loan alone. A DSCR cash-out replaces the first with a single new loan, and it makes sense when you need proceeds above what the line can reach, or when the first is not low enough to protect.
| Factor | DSCR HELOC (second lien) | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| Structure | Revolving, draw and repay | One lump sum |
| Leverage ceiling | 70% CLTV on a second lien | Typically 75% LTV on a standard rental, 70% on short-term-rental collateral |
| Size | $50,000 to $500,000 | Larger proceeds possible |
Blended cost is the honest test. A cheap first plus a pricier second can cost less or more than one new loan, depending on balances and terms. Compare the two on the combined monthly obligation, using the lender’s disclosures. As one banker argued on BiggerPockets, a second at a much higher cost can end up costing more than a refinance. That is a forum opinion, not a rule. Run your own balances.
For the cash-out side, Lendmire’s DSCR cash-out refinance page covers the structure. Lendmire’s piece on what an investment property HELOC requires while keeping a low first mortgage goes deeper on qualifying.
Why the Line Comes In Smaller Than Expected
Four things shrink it.
1. The first balance is a bigger share of value than you thought. Pull a current valuation estimate before you plan around a number.
2. The stress payment on the full limit. Coverage runs on the whole line, so a large limit with modest rent fails at 1.10x.
3. Rent used for lender review is the lesser figure. Market rent from the appraisal and the lease both set the ceiling, absent three months of receipts supporting a lease above market.
4. Credit between 700 and 719. A second lien needs 720. At 700 to 719 with a first mortgage, the second-lien tier is simply not there.
What Happens When the Draw Period Ends
Payment shock is real on any HELOC. The CFPB explains that a HELOC is an open-end line you can borrow against repeatedly during a draw period, followed by a repayment period. On this program the draw period is 5 years interest-only on the drawn balance. Then a 25-year fully amortizing repayment period begins, and the rate is variable. Payments on the same balance rise when repayment starts, because principal joins the payment.
Plan the exit before the draw. If the line funds a down payment on a new rental, the new property’s rent needs to carry the combined load by the time repayment begins. The CFPB’s HELOC booklet covers the general disclosures, including that a lender can freeze or reduce a line in some circumstances. The rate and the pricing terms come with the lender’s HELOC disclosures.
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.
Documents to Gather
- The lease, plus three months of rent receipts if the lease sits above market rent.
- The current first mortgage statement.
- Entity documents if the property is in an LLC, with guarantor signatures.
- Insurance for both liens, with flood coverage where required.
- Title information and proof of the date you took title.
Clean documents leave fewer gaps for the lender to chase. They do not change what the program allows. Lendmire’s complete DSCR loans guide explains the broader product family.
Frequently Asked Questions
Can I use a DSCR HELOC if my rental is in an LLC?
Yes, an investment-property line can be vested in the owner’s LLC, depending on program guidelines. The borrowers on the line need not match the borrowers on the first mortgage.
Does a higher credit score raise how much I can borrow on a second lien?
No. On a second lien, 720 or better reaches 70% CLTV, and no higher tier exists. Score matters more on a first lien, where 740 or better reaches 75% LTV and 700 to 739 reaches 70% LTV. All of it is subject to underwriting. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
How soon after buying a rental can I open the 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).
Do I have to draw the whole line?
At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. After that, each draw is at least $5,000, and the draw period runs 5 years interest-only on the drawn balance.
What if I need more than $500,000?
A second-lien line stops at $500,000. A first-lien line on a rental with no mortgage can run to $1,000,000, but above $500,000 the ceiling is 65% LTV at 720 or better. A DSCR cash-out refinance is the alternative when you need larger proceeds and are willing to replace the first.
Does the program accept any rental?
No. Rural-designated property, row homes, condotels, leaseholds, and several other types are outside it, and a declining-market flag lowers the ceiling by 5 points. Warrantable and non-warrantable condominiums are eligible property types.
