The Quick Read: Big banks rarely write a rent-qualified line behind a first mortgage on a rental, so the real answer sits in the non-bank channel, where the highest combined leverage behind a first lien is 70% CLTV at a 720 score or better, on lines of $50,000 to $500,000, subject to underwriting. CLTV means combined loan-to-value: the first mortgage plus the new line, divided by the property’s value. The figures below come from select programs in the wholesale network Lendmire works with, and they are ceilings, not offers.
- A standalone second lien on a non-owner-occupied rental tops out at 70% CLTV, and it needs a 720 score or better.
- A first lien on a rental with no mortgage reaches 75% LTV at 740 or better, and 70% from 700 to 739.
- The rent qualifies the line at a 1.10x DSCR (debt service coverage ratio: monthly rent divided by the qualifying payment), with no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines.
- The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Which Banks Offer a DSCR HELOC With the Highest Combined LTV?
Few traditional banks offer one, and this page will not rank any. The question has a built-in mismatch. A bank that writes a HELOC on a rental usually is reviewed against personal income and debt-to-income ratio. A DSCR HELOC qualifies the property instead.
Rent-qualified second liens come mainly from non-bank and non-QM channels. Non-QM means the loan sits outside standard agency mortgage rules. Lendmire is a mortgage broker, not a lender. It works with a network of wholesale DSCR HELOC lenders and matches a file to the program that fits.
Even for the bank products, the market is thin. A BiggerPockets discussion of HELOCs on investment property points out that few lenders still write them. It also notes that a so-called HELOC on a rental often turns out to be a closed-end second with no further draws.
So “highest combined LTV” is not a bank-by-bank contest. The lenders that write this depend on your credit tier, property type, lien position and how much leverage you need. The best program for your situation is the one whose tier matches your score and your first mortgage balance. A broker that sees several programs can sort that out before you apply.
Key Terms Defined
HELOC: a revolving line of credit secured by the property. You draw, repay and draw again within the limit.
Second lien: a loan recorded behind a first mortgage. If the property is sold or foreclosed, the first lien is paid first.
First lien: a loan in first position on a rental that has no other mortgage.
Closed-end second: a one-time lump-sum loan behind the first mortgage. It does not let you borrow again as you repay.
AVM: an automated valuation model, a computer estimate of the property’s value.
How Underwriting Treats the Line, Step by Step
A DSCR HELOC is a revolving line 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.
Here is how the deal works.
1. The structure is set. Your first mortgage stays in place. 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 an acknowledgment. The borrowers on the line need not be the borrowers on the first mortgage.
2. The rent is tested. The line must reach a 1.10x DSCR. That is gross monthly rent divided by a stress payment, which is a fully amortizing payment on the entire credit limit with a 2-point cushion above the starting pricing. Taxes and insurance are not part of that payment. The lender never calculates your personal income.
3. The rent figure is chosen. 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 may have at most one vacant unit.
4. The first mortgage is counted. Whether the first-mortgage payment joins the coverage test on a second lien depends on the lender’s own calculation. Confirm on the file how the lender treats it. The qualifying arithmetic here is illustrative, and the lender’s calculation governs.
5. Every lien is counted against value. CLTV adds the first mortgage balance and the full new line, then divides by value. Unused room still counts. A consumer explainer on second HELOCs makes the same point about most lenders: they use the credit limit, not the current balance.
6. Credit and history are checked. The ceiling follows your credit tier. There must be no 30-day mortgage late in the last 12 months. At least 48 months must have passed since a bankruptcy, foreclosure, short sale or deed-in-lieu.
Only the income test changes. Credit, equity, the property and title are all still reviewed. For the full picture of how these loans work across products, see Lendmire’s complete DSCR loans guide.
The Leverage Ladder
The ceiling depends on lien position and credit tier, and the tiers do not overlap. The table lists each one for a non-owner-occupied one-to-four-unit rental, through select programs and subject to underwriting.
| Position on a rental | Credit score | Ceiling | Line size |
|---|---|---|---|
| Second lien | 720 or better | 70% CLTV | $50,000–$500,000 |
| Second lien | Below 720 | None | Not available |
| First lien (no mortgage) | 740 or better | 75% LTV | Up to $500,000 |
| First lien (no mortgage) | 700–739 | 70% LTV | Up to $500,000 |
| First lien (no mortgage) | 720 or better | 65% LTV | Over $500,000 to $1,000,000 |
Two readings matter. First, the second-lien ceiling is 70% CLTV and never higher on a rental. Second, a borrower who keeps a first mortgage can take only a second lien, which carries the 720 floor. A first lien exists only on a rental with no mortgage.
Primary-home HELOCs sometimes advertise much higher combined leverage. That is a different, owner-occupied product. This line is never offered on an owner-occupied home, so do not read a primary-residence figure as a rental number.
How Much Room Is Left Behind Your First?
The maximum line equals value times the CLTV ceiling, minus the first mortgage, then capped at the program’s dollar limit. The first mortgage eats most of the room. Say you own a rental and your first mortgage is a given share of its value. This table shows what is left under a 70% CLTV ceiling on a second lien.
| First mortgage as % of value | Room left (share of value) |
|---|---|
| 40% | 30% |
| 50% | 20% |
| 60% | 10% |
| 65% | 5% |
| 70% or more | None |
Lines start at $50,000, so a thin sliver of room works only on a high-value property. At 65% of value, the property would need to be quite valuable for 5% to reach the minimum line. The binding constraint is usually leverage, not rent coverage. A property can clear the 1.10x test and still fail the CLTV test.
A low appraisal shrinks the room further. Value sits in the denominator, so a lower number cuts the line in direct proportion.
Where the General Rule Breaks
Credit between 700 and 719. With a first mortgage, you have no second-lien cell. A 700 score works only for a first lien on a rental with no mortgage, and then at 70% LTV. Raising the score above 720, or looking at a DSCR cash-out refinance, are the usual alternatives. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
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).
Draws are front-loaded. 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. The draw period is 5 years of interest-only payments on the drawn balance. Then a 25-year fully amortizing repayment period follows, with a 30-year maturity. The line is variable-rate.
Lenders can freeze a line. The CFPB’s HELOC overview notes that a lender may stop further draws if the home’s value drops significantly. Treat the undrawn balance as conditional.
Value path. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, plus 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. A rehab may not show up in an automated value, so a full appraisal is the cleaner route when you want improvements counted. Value gains are not guaranteed and depend on comps and underwriter review.
Property types. Single-family, PUD, townhome, two-to-four-unit and condominium properties are eligible, along with lots up to 10 acres. Several types fall outside this lane: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts and age-restricted communities. So do hobby farms, modular and log homes, land contracts, mixed-use property, a property listed for sale in the prior 2 months and a property with a solar lien. A declining-market flag lowers the ceiling by 5 points. Hazard insurance must cover both liens, with flood coverage where required.
Borrower limits. US citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not. Exposure is capped at 5 loans or $2,500,000 per borrower with the program. There are no reserve or cash-to-close requirements, subject to underwriting.
HELOC, Cash-Out Refinance or Closed-End Second?
Pick the line when you want to keep a low-cost first mortgage in place and take equity in pieces. Pick a cash-out refinance when you need the highest leverage or one lump sum. A DSCR cash-out replaces the first mortgage, so it can reach higher combined leverage than a second lien. Doing so means giving up the existing first.
A closed-end second behind your first gives a lump sum with no further draws. It fits a one-time need. The line fits staged projects, such as a rehab funded over time.
A bank HELOC on a rental, with personal income as the test, may suit a borrower whose tax returns show strong income. Few traditional banks offer one, though, so a borrower whose state has no lender writing a rent-qualified line may still need to look at a bank product. The DSCR line fits a borrower whose tax returns understate cash flow, or one who wants the LLC on title.
Lendmire’s piece Banks That Offer an Investment Property HELOC Behind an Existing First covers that structure from the personal-income side. Its piece on investment property HELOCs behind a DSCR first lien covers the case where the first mortgage is itself a DSCR loan.
What to Ask Before You Apply
- Is the line revolving or closed-end, and can I draw again after repaying?
- What is the ceiling for my credit tier and lien position?
- Does the lender count the first-mortgage payment in the coverage test?
- Is an automated valuation allowed for my line size, or does it need a full appraisal?
- Can my LLC stay on title, and who signs?
- Does my property type, or its market, trigger a lower ceiling?
- How does the draw schedule work at closing and afterward?
Frequently Asked Questions
Do big banks offer a HELOC on a rental property?
Some do, but many do not. Those that do usually qualify you on personal income, and the lender pool is smaller than for a primary home. A DSCR HELOC qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. It is placed through a wholesale lender rather than a retail bank.
Does the undrawn part of the line count toward CLTV?
Yes. CLTV uses the full credit limit plus the first mortgage balance, not just what you have borrowed. At least 80% of this program’s line is drawn at closing anyway, so the unused portion is small. An unused line still uses up CLTV room if you stack more than one.
Can my LLC take the line?
Vesting in an LLC is allowed on investment property, 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.
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).
Is this available in every state?
No. It is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
