The Quick Read: It depends on the rental’s value, the credit score and the first mortgage you keep, because the line is sized as value times the allowed combined leverage, minus what is already owed. Through select programs, a second-lien line on a rental typically reaches 70% combined loan-to-value (CLTV) at a 720 score or better, with lines from $50,000 up to $500,000. Subject to underwriting, the numbers below are ceilings, not offers.
- Second lien: up to 70% CLTV (first mortgage plus the new line, divided by value), lines to $500,000.
- First lien on a rental with no mortgage: up to 75% loan-to-value (LTV) at 740 or better, 70% at 700 to 739, and 65% on lines above $500,000, which run to $1,000,000.
- Qualification: the rent must cover a stress payment on the whole line at a minimum 1.10x. No traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines.
- Online: you can start the application online, but the valuation, title and credit review still happen on the file.
The Short Version of the Math
The amount you can borrow is value times the allowed leverage, minus every lien already on the property. That is the whole formula.
The federal consumer-finance regulator’s HELOC booklet describes lenders setting a credit limit as a percentage of the home’s value, then subtracting what you owe. Its worked example is a consumer illustration, not a rental rule. The shape is the same, though, and rentals simply get tighter percentages.
Three things can shrink the result after that. The first is the credit-score tier. The second is the dollar cap on the line. The third is the rent test, which can cap the line even when equity is plentiful.
What Is a DSCR HELOC, and How Is It Different From a Home Equity Loan?
A DSCR HELOC is a revolving line of credit secured by a rental you keep. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. A home equity loan is a lump sum. Both are second mortgages if you already have a first.
The federal consumer-finance regulator explains the split: a HELOC lets you borrow, repay and borrow again during a draw period, then moves to repayment. Payments move with the balance and the variable rate.
The program described here is a line, not a lump sum. It is written as a standalone second lien behind the first mortgage you keep. It can also be a standalone first lien on a rental with no mortgage. It is never closed together with a purchase, never a third lien, and never a line on your own home or a second home.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. For the wider picture, see Lendmire’s complete DSCR loans guide.
How Is the Amount Calculated, Step by Step?
Work through five steps in order. The smallest result is your real number.
1. Establish value. Lines to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal. Appraisal waivers are not accepted.
2. Apply the leverage ceiling. Value times the allowed CLTV (second lien) or LTV (first lien) gives total debt allowed.
3. Subtract existing liens. Take out the first mortgage balance. A rental with no mortgage subtracts nothing. The whole credit limit counts in the test, drawn or not.
4. Check the dollar range. Lines start at $50,000. Second liens stop at $500,000. First liens reach $1,000,000 but drop to 65% LTV above $500,000.
5. Run the rent test. Gross monthly rent divided by a qualifying payment must reach 1.10x. That 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, not taxes and insurance. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Step five surprises people. Because the stress payment applies to the whole line, a bigger line raises the bar the rent has to clear. 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. On a two-to-four-unit property, at most one unit may be vacant. Whether the first-mortgage payment joins that calculation on a second lien is something to confirm on the file, because the lender’s own coverage calculation governs.
What Do the Leverage Tiers Look Like?
Second liens top out at 70% CLTV, and first liens at 75% LTV. Credit score decides where you land. Each ceiling applies to a non-owner-occupied rental, subject to underwriting. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
| Lien position | Credit score | Maximum | Line size |
|---|---|---|---|
| Second lien | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien | 740 or better | 75% LTV | To $500,000 |
| First lien | 700 to 739 | 70% LTV | To $500,000 |
| First lien | 720 or better | 65% LTV | Above $500,000 to $1,000,000 |
Below 720, there is no second-lien option. A borrower who keeps a first mortgage can only take a second lien, so a 700 to 719 score with a mortgage in place does not fit this program. A first lien exists only on a rental with no mortgage.
Two adjustments can pull the ceiling down. A property in a market flagged as declining loses 5 points. Philadelphia lines carry a ceiling 10 points lower.
Worked Examples: Ample Equity, Thin Equity, No Room
Three scenarios show how the same formula gives very different answers. These use percentages and ratios only, and the lender’s own calculation governs.
Ample equity. Picture a rental held for years, valued at $500,000, with a modest first mortgage and a 720 score. At 70% CLTV, total debt allowed is $350,000. Once the first mortgage balance comes out, a healthy slice remains. The line can clear the $50,000 minimum with room to spare. The next gate is the rent test, which on a well-rented property often leaves cushion above 1.10x.
Thin equity. Say you own a $300,000 duplex and the first mortgage already sits near 65% of value. At 70% CLTV, only about five points of value remain. That is likely below the $50,000 minimum line, so the formula returns a number the program cannot use. The percentage binds before the rent does.
No room. Consider a rental bought recently with a high-leverage first mortgage, already at or past 70% CLTV. The formula returns zero. Paydown or appreciation has to create room first. Seasoning would block the file anyway, as covered below.
Run the numbers on a fourth case where the rent binds. Say you own a rental free and clear, valued well above $1,000,000, and you want the largest first-lien line. Equity is no issue. A line that size must clear 1.10x on a full-line stress payment, so the rent has to be large relative to the line. A property that rents modestly may support a smaller line than the equity allows.
What Shrinks Your Number?
Several levers move the amount, and most are visible before you apply. Check each against your property.
- Credit tier. A 720 score unlocks the second-lien cell. First-lien leverage steps from 70% to 75% at 740.
- Existing liens. Every dollar owed ahead of the line comes straight off the top.
- Line size. A larger line raises the stress payment. At the top, first-lien leverage falls to 65%.
- Rent evidence. The lesser of market rent and the lease is used, unless three months of receipts support a lease above market.
- Vacancy. A two-to-four-unit property may have at most one vacant unit.
- Market flags. Declining-market and Philadelphia adjustments cut the ceiling.
- Mortgage history. No 30-day late in the last 12 months. 48 months must have passed since a bankruptcy, foreclosure, short sale or deed-in-lieu.
The exposure cap matters for portfolio owners. A borrower can hold at most 5 loans or $2,500,000 with the program, so model each rental separately.
Which Rentals Are Eligible?
Single-family homes, PUDs, townhomes, two-to-four-unit properties and condominiums are eligible, including non-warrantable condos. Lots up to 10 acres also qualify. Leverage tiers above govern every property type.
Several property types sit outside this program: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts and mixed-use. A property listed for sale in the prior 2 months or carrying a solar lien is also out.
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.
Can an LLC Hold Title?
Yes, on an investment property. Vesting in your LLC is allowed. The members sign as guarantors, and 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.
This matters because bank-style rental HELOCs often refuse LLC ownership. An investor discussion on BiggerPockets reflects the same pattern, though it is anecdotal. A line that tolerates the entity can be the difference between a workable plan and a retitling headache.
What About 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). A recent purchase therefore leaves no room, regardless of equity.
How Does the Draw Work?
The structure is more fixed than a bank line, and that shapes how you size it.
- Closing draw: at least 80% of the line is drawn at closing, and that draw is never less than $50,000. On the smallest lines, the whole line is drawn at closing.
- Later draws: at least $5,000 each.
- Draw period: 5 years, interest-only on the drawn balance.
- Repayment: a 25-year fully amortizing period, with a 30-year maturity.
- Rate: variable. The rate and the pricing terms come with the lender’s disclosures.
Because most of the line is drawn up front, this is not a standby line you leave mostly unused. Size it to what you will actually deploy. The CFPB notes that falling behind on a HELOC can cost you the property, and the lien here sits on your rental. Size with that in mind.
HELOC, Home Equity Loan or Cash-Out Refinance?
The right tool depends on whether you want to keep your first mortgage. Each product answers a different question.
| Factor | DSCR HELOC | Closed-end second | Cash-out refinance |
|---|---|---|---|
| Structure | Revolving line | Lump sum | Replaces first mortgage |
| First mortgage | Stays in place | Stays in place | Paid off and reset |
| Payments | Vary with balance | Set at funding | New fixed schedule |
| Best for | Staged deployment | One-time use | Large reset, new terms |
The main reason to choose a second lien is to leave the first mortgage alone. A cash-out refinance resets the whole balance. If your first mortgage has terms worth protecting, a second lien keeps them. If you want one new loan and a fresh structure, a DSCR cash-out refinance may fit better.
Why Do Banks Often Say No?
Most big banks do not offer these lines on rentals at all. NerdWallet reports that investment-property HELOCs are possible but not offered by all lenders, with strict requirements and a debt-to-income test. A DSCR line replaces that personal-income test with the rental’s own coverage.
That difference matters most to self-employed owners and to investors with heavy debt from other rentals. They can look weak on paper at a bank while holding strong properties. The rent test judges the property, though credit, title, value and rent evidence are all still reviewed. For a plain-English walk through of the application side, Lendmire’s piece How to Qualify for an Investment Property HELOC or Home Equity Loan Online covers it.
Can You Do It Entirely Online?
You can begin online, but online does not mean unreviewed. Expect the valuation, title review and credit pull to run on every file. Hazard insurance must cover both liens, with flood coverage where required. Title is a full policy on a first lien and on second liens above $400,000, and an owner-and-encumbrance report on smaller second liens.
Borrowers must be US citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. No reserves and no cash to close are required, subject to underwriting.
Where is it offered? The program runs in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is a broker that arranges the line through a wholesale lender in its network. It is not the lender.
What If the Number Comes Back Too Low?
Run through the alternatives before giving up. The first is paying down the first mortgage to create room under the ceiling. The second is clearing the seasoning clocks, or waiting for the property’s value to rise enough to widen the equity cushion. A third is a smaller line that clears the $50,000 minimum. A fourth is a cash-out refinance, which sizes differently because it replaces the first mortgage.

Frequently Asked Questions
What is the maximum I can borrow on a rental through this program?
A second lien tops out at $500,000 and 70% CLTV at a 720 score or better. A first lien on a rental with no mortgage reaches $1,000,000, but leverage falls to 65% LTV above $500,000. These are ceilings through select programs, subject to underwriting. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Do I need to show tax returns or W-2s?
No. The line 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 calculation. Credit, title, the valuation and rent evidence are still reviewed.
How long must I own the rental first?
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).
Can my LLC hold title?
Yes, on an investment property. Program eligibility is set by the lender.
How much of the line do I have to draw?
At least 80% of the line is drawn at closing, and that draw is at least $50,000. On the smallest lines, that means the whole line. Later draws are at least $5,000 each, during the 5-year draw period.
