The Quick Read: On a rental you keep financed, the line is capped at 70% combined loan-to-value at a 720 credit score or better, minus your first mortgage balance, and it tops out at $500,000, subject to underwriting. A rental with no mortgage can reach 75% loan-to-value at 740 or better, up to $1,000,000 at lower leverage on larger lines. The rent must also cover a stress payment on the whole line, so the smaller of the two limits sets your number. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
- Second lien: up to 70% CLTV (first mortgage plus new line), 720 minimum score, lines from $50,000 to $500,000.
- First lien on a rental with no mortgage: up to 75% LTV at 740 or better, 70% from 700 to 739, and 65% on lines above $500,000.
- Rent must reach a 1.10x coverage ratio on a stress payment calculated on the entire limit.
- At least 80% of the line is drawn at closing, with a 5-year interest-only draw period.
A DSCR HELOC is a revolving line of credit on a non-owner-occupied one-to-four-unit rental. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire is a broker, and the line is placed through select lenders in its wholesale network. The sections below show how the number is built, which limit binds first, and when a different product fits better. For the broader picture, see the complete DSCR loans guide.
How Is the Maximum Line Calculated?
The formula has three steps: property value times the combined leverage cap, minus every lien already recorded, then a check against the dollar cap and the rent test. Equity alone is not borrowing power. The CFPB defines equity as the home’s value minus what is owed on the mortgage, but a lender lends only up to a percentage of value, so usable room is smaller than raw equity.
Take a rental valued at 100 units of value. At 70% CLTV, total liens cannot exceed 70. If the first mortgage sits at 55% of value, the line can reach about 15% of value. If the first sits at 65%, only about 5% is left. That second case is why a recently purchased, highly leveraged rental often has little room.
Two further points shape the answer:
- A higher score does not buy more leverage on a second lien. The program has one cell: 720 or better, 70% CLTV. Below 720 there is no second-lien option.
- The line runs from $50,000 up, so a thin-equity property may fall below the minimum even when some room exists.
Which Limit Binds First?
Three ceilings compete, and the lowest one wins: the equity room, the rent coverage, and the dollar cap. Owners of higher-value rentals can hit the dollar cap, and owners with modest rent can hit the coverage test before either.
| Binding limit | What it looks like | What to do |
|---|---|---|
| Equity room | First mortgage already near 65% of value | Wait for paydown or appreciation |
| Rent coverage | Rent too low against the stress payment on the full line | Request a smaller line |
| Dollar cap | Valuable property with large equity | Consider a first-lien structure or a cash-out refinance |
The coverage test deserves attention because it is calculated on the entire credit limit, not only the drawn balance. Rent used for lender review is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The qualifying payment is principal and interest on the full line at a stress rate, and it must be covered at 1.10x or better. Taxes and insurance are not part of that qualifying payment. Confirm on the file how the lender treats the first-mortgage payment on a second lien, because the lender’s own coverage calculation governs.
Practically, a larger line means a larger stress payment, so shrinking the request is the fix when rent is the constraint. A line sized to fit the rent often clears when the maximum does not.
What Changes Between a Second Lien and a First Lien?
A second lien sits behind the first mortgage you keep. A first lien exists only on a rental with no mortgage. They carry different leverage and score tiers, so lien position decides your ceiling more than any other variable.
| Factor | Second lien | First lien |
|---|---|---|
| Property status | First mortgage stays in place | No mortgage on the rental |
| Leverage | Up to 70% CLTV | Up to 75% LTV |
| Credit minimum | 720 | 700 |
| Line range | $50,000 to $500,000 | To $1,000,000 |
On a first lien, 740 or better reaches 75% LTV on lines up to $500,000, and 700 to 739 reaches 70%. Lines above $500,000 carry a lower 65% LTV ceiling. The first-lien figures are LTV; the second-lien figures are CLTV because the existing mortgage counts toward the total. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
A borrower who keeps a first mortgage can only take a second lien, which requires 720. A 700-to-719 borrower in that position is held back by the score, not by lien position.
Worked Example: Three Rentals, Three Different Answers
These examples use modeled assumptions, expressed as percentages and ratios. They illustrate the logic; the lender’s own calculation governs.
Rental A, thin equity. The first mortgage is at 66% of value. Under a 70% CLTV cap, only about 4% of value is available. That is likely below the $50,000 minimum unless the property is quite valuable. Equity room binds.
Rental B, strong equity, modest rent. The first mortgage is at 40% of value, leaving up to 30% of value in theory. But the rent covers the stress payment on a full-size line at only about 1.0x. The line must shrink until coverage reaches 1.10x. Rent coverage binds.
Rental C, high value, low debt. The first mortgage is at 30%, so equity room could exceed $500,000. The dollar cap stops the line at $500,000. Cap binds. An owner in this spot with no mortgage at all might look at the first-lien structure, which reaches $1,000,000 at 65% LTV on larger lines.
The pattern: run equity room first, then test the rent against a payment on the full line, then compare to the cap. The smallest number is your realistic line.
HELOC vs. Other Ways to Pull Equity
A DSCR HELOC and a DSCR cash-out refinance solve different problems. The line leaves your existing first mortgage untouched. A cash-out replaces it, which can reach higher leverage and larger amounts but resets the whole loan.
| Product | Existing first mortgage | Structure |
|---|---|---|
| DSCR HELOC | Stays in place | Revolving second or first lien |
| DSCR cash-out refinance | Replaced | New first-lien loan |
| Personal-income investment HELOC | Stays in place | Qualified on the owner’s income and DTI |
A personal-income HELOC on a rental, offered by banks and credit unions, is a different product with its own rules. NerdWallet notes that HELOCs on investment property are harder to get than on a primary home, with typical requirements around a 720 credit score and at least 20% equity. That is a market-wide survey point, not a statement about this network. Here, the rent qualifies the line, with no traditional personal-income documentation, W-2s or personal income calculation. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
If the existing first mortgage carries a favorable term, a second lien avoids disturbing it.
What Are the Draw, Repayment and Seasoning Rules?
The line has a 5-year interest-only draw period on the drawn balance, then a 25-year fully amortizing repayment period, for a 30-year maturity. The rate is variable. At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000, so on the smallest lines the whole amount is drawn at closing. Later draws are at least $5,000.
That draw structure makes this a real loan, not a standby cushion. Size the line to what you will deploy, because the stress payment is computed on the full limit and most of it funds immediately.
Plan for payment shock when the draw period ends. Interest-only payments become fully amortizing payments over 25 years, and variable pricing can move the payment too. The CFPB also warns that falling behind on a HELOC can put the property at risk. On a rental with vacancy risk, test whether the rent still covers the repayment-phase payment before drawing.
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). A recent purchase therefore leaves no room at all.
Why Might Your Number Come in Lower?
Several file features trim the line below the headline ceiling:
- Recent purchase or refinance. Seasoning blocks eligibility entirely until the clocks run.
- High existing first mortgage. Equity room shrinks fast above 55% of value.
- Property type. Rural-designated property, row homes, condotels, leaseholds, mixed-use and properties listed for sale in the prior 2 months fall outside the program. Single-family, PUD, townhome, two-to-four units and condominiums are eligible property types, and the leverage tiers above apply to each.
- Vacancy. A two-to-four-unit property may have at most 1 vacant unit, and a lease in place is required.
- Valuation. Lines to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines require a full interior appraisal. Appraisal waivers are not accepted.
- Exposure. A borrower is limited to 5 loans or $2,500,000 with the program.
- Borrower status. US citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
Title can stay in an LLC on an investment property, with members signing as guarantors, subject to program terms. That matters because a personal-income equity line generally cannot be held in an LLC. Lendmire’s article How to Tap Home Equity Without Tax Returns Using a Bank Statement HELOC covers the alternative documentation route for owners who want to compare.
Key Terms Defined
CLTV: Combined loan-to-value, meaning the first mortgage balance plus the new line, divided by the property’s value.
Draw period: The 5-year stretch when payments cover interest on the drawn balance only.
Lien position: Whether the line sits behind an existing mortgage (second) or stands alone as the only loan (first).
Stress payment: The qualifying payment on the full credit limit, used only to test rent coverage.
Seasoning: The required time since your last purchase or refinance and on title before the line is available.
Frequently Asked Questions
What is the most I can borrow on a rental that still has a mortgage?
Up to $500,000, as a second lien, and only if combined leverage stays at or below 70% CLTV at a 720 score or better. The first mortgage balance counts toward that limit, so the available line can fall well below the cap. Everything remains subject to underwriting and the rent coverage test.
Does a higher credit score raise my line?
Not on a second lien, which has a single 720-or-better tier at 70% CLTV. On a first lien, score does matter: 740 or better reaches 75% LTV, while 700 to 739 reaches 70%. Larger first-lien lines above $500,000 carry 65% LTV at 720 or better. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
How long must I own the property before applying?
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 before a file moves forward.
Can an LLC hold the property?
Yes, 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. Borrowers on the line need not match the borrowers on the first mortgage.
Do I need tax returns or a personal income calculation?
No. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The lease, the credit report and the valuation are still documented. Tax treatment varies; consult a qualified professional.
Estimating Your Line Before You Apply
Work through it in order: estimate value conservatively, multiply by 70% for a second lien, subtract the first mortgage balance, then compare the result to the $50,000 minimum and $500,000 cap. Next, check whether rent clears 1.10x against a stress payment on that full amount, and shrink the request if it does not.
