Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
The Quick Read: It depends on how much of the rental’s value is already pledged, because 70% is a combined ceiling and the existing first mortgage uses part of it. Your line is 70% of the property’s value minus the first-mortgage balance, capped at $500,000, subject to underwriting and the rent test. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
- A 735 score clears the 720 minimum for a second-lien line, so the score is not what limits you.
- On a second lien, the ceiling is 70% combined loan-to-value (CLTV): the first mortgage plus the new line, divided by value.
- On a rental with no mortgage, a 735 score sits in the 700-to-739 band, which allows 70% loan-to-value (LTV) on a first-lien line up to $500,000.
- Lines start at $50,000, and at least 80% of the line is drawn at closing.
Key Terms Defined
DSCR (debt service coverage ratio): Gross monthly rent divided by the qualifying payment on the loan.
LTV (loan-to-value): One loan balance divided by the property’s appraised value.
CLTV (combined loan-to-value): All loans secured by the property, added together, divided by value. A second-lien line is measured this way.
Lien position: Whether the lender is paid first (first lien) or after another mortgage (second lien).
Draw period: The stretch when you can borrow from the line and pay interest only on what you drew.
What Does 70% Actually Mean on a DSCR HELOC?
It means total debt against the rental can reach 70% of its value, not that you can borrow 70% of value. The new line gets whatever room is left after the existing mortgage.
A DSCR HELOC is a revolving line of credit on a non-owner-occupied one-to-four-unit rental. It is written as a standalone second lien behind the first mortgage you keep. On a rental with no mortgage, it is written as a standalone first lien. The rent qualifies the line. Your personal income is not calculated, and the owner’s LLC can stay on title, subject to program terms.
The sizing formula is simple:
Maximum line = (appraised value × 70%) − first-mortgage balance
Housing regulators teach the same logic for any home equity line. A borrower can generally borrow up to a set percentage of equity, and equity is value minus what is owed. The CFPB’s HELOC brochure lays that out for owner-occupied homes. A DSCR line works the same way on a rental, but with a rent test and its own caps.
If your first mortgage already equals 60% of value, only 10 points of value remain under a 70% ceiling. That is why two investors with the same score and the same 70% program can get very different lines.
The Math in Percentages: How Much Room Is Left?
Room equals 70% of value minus your first-mortgage balance, shown as a share of value. The table uses shares of value instead of dollar amounts, because your own appraisal sets the real number.
| First mortgage as % of value | Lien position | Room under the ceiling |
|---|---|---|
| None | First lien | 70% of value (735 score) |
| 30% | Second lien | 40% of value |
| 50% | Second lien | 20% of value |
| 60% | Second lien | 10% of value |
| 65% | Second lien | 5% of value |
| 70% or more | Second lien | None |
Two limits then trim the result. The first is the program’s $500,000 cap on a line at this leverage. On a higher-value rental with little debt, the cap binds before the percentage does. The second is the $50,000 minimum line. If the room left is smaller than that, there is no line to write.
Other items can shrink the result below the formula. A declining-market flag lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower. A value that comes in under your estimate cuts the room, and every point of value moves the line.
Run the formula yourself in three steps:
1. Take your best estimate of current value and multiply by 0.70. 2. Subtract the payoff balance on the first mortgage. 3. Compare the remainder with $500,000 and with the $50,000 minimum.
What Your 735 Credit Score Does and Doesn’t Change
Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
A 735 score qualifies you but does not raise the percentage. On a second lien, anyone at 720 or better gets the same 70% CLTV ceiling, so 735 and 790 sit in the same leverage cell. Below 720 there is no second-lien tier at all.
The score matters in two other ways. It is read from the lender’s own credit report, and it places the file in a tier. Pricing on non-QM lines is also tiered, though the rate and pricing terms come with the lender’s disclosures, not from this article. A practitioner thread on BiggerPockets describes the same pattern: higher leverage costs more, and scores are priced in small bands.
The first-lien path is where 735 has a visible edge. For a rental with no mortgage, the program offers 75% LTV at 740 or better and 70% LTV from 700 to 739, on lines up to $500,000. At 735, you sit five points under the top band. If you are close to 740 and have a free-and-clear rental, a small score improvement may be worth pursuing before you apply. For a second lien, there is no such step to chase.
Credit history counts too. The program looks for no 30-day mortgage late in the last 12 months. It also looks for at least 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. Scores at or above 700 skip the tradeline-depth rules.
The Rent Test Can Cap You Before Leverage Does
The rent must cover a stress payment on the entire credit limit at 1.10x or better. That payment is a fully amortizing payment on the whole line, not just the drawn amount, at the start rate plus 2 percentage points. Taxes and insurance are not part of it.
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. A two-to-four-unit property may have at most one vacant unit.
Because the test runs on the full limit, a larger line raises the qualifying payment even if you draw less later. Consider a rental with plenty of equity but modest rent. The leverage math might allow a big line, while the rent covers the stress payment at only about 1.05x. That is under 1.10x. The usual fix is a smaller line, and the line that passes may be well below the 70% number.
One detail is worth confirming on your own file. On a second lien, the published program facts do not say whether the first-mortgage payment joins the qualifying payment. Ask how the lender treats the first-mortgage payment, since the lender’s own coverage calculation governs. That answer changes how much rent you need.
Second Lien or First Lien: Which Path Fits You?
If you keep a first mortgage, you can only take a second lien. A first lien exists only on a rental with no mortgage. The two paths use different yardsticks.
| Feature | Second lien | First lien |
|---|---|---|
| Existing mortgage | Stays in place | None on the rental |
| Leverage measure | CLTV | LTV |
| Ceiling at 735 | 70% | 70% on lines to $500,000 |
| Minimum score | 720 | 700 |
| Top-tier ceiling | 70% at 720+ | 75% at 740+ |
| Largest line | $500,000 | Up to $1,000,000 |
Lines above $500,000 on a first lien carry a 65% LTV ceiling at 720 or better. So a larger line comes with less leverage, and at 735 the big-line path tops out lower than the standard one. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Before you choose, check these points against your situation:
- Keep the first mortgage if its terms are worth keeping. A second-lien line taps equity without resetting the whole loan.
- Use the first-lien path only if the rental is truly free and clear. A rental with a small balance is still a second-lien case.
- Expect the same lien rules on LLC-held properties. Subject to lender program eligibility, the members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment.
What the File Looks Like
The lender needs a value, a lease, a credit report and clean title. Valuation depends on the size of the line. Lines up to $400,000 use an automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
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).
Reserves and cash to close are not required. A single borrower can hold at most five loans or $2,500,000 with the program.
Property type matters. Single-family homes, planned unit developments, townhomes, two-to-four-unit buildings and condominiums are eligible. Rural-designated property, row homes, condotels, leaseholds, land trusts and mixed-use are not. A property listed for sale in the prior two months is out. So is one with a solar lien.
Borrowers must be U.S. citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Across the wholesale network, program rules vary by lender, so the figures here describe the select program Lendmire places files with, subject to underwriting.
What You Owe After the Draw: How the Line Behaves
The line has a 5-year interest-only draw period. A 25-year fully amortizing repayment period follows, 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. On the smallest lines, that means the whole line is drawn at closing. Later draws are at least $5,000 each. The CFPB’s overview of home equity lines describes the same two-stage design: a draw period, then repayment.
Two practical points follow. A line drawn mostly at closing starts with real interest cost on day one, so size it for the project in hand. And the payment steps up when the draw period ends and amortization begins. Plan the exit before that date: a sale, a refinance, or enough rent growth to carry the higher payment.
When the Math Leaves Little or No Room
If your first mortgage already uses 60% or more of value, the line may be too small to be worth setting up. Here are the usual alternatives.
| Option | How it works | Fits when |
|---|---|---|
| DSCR cash-out refinance | Replaces the first mortgage with a new, larger loan | The old first mortgage has no special value |
| Smaller line | Reduces the stress payment on the whole limit | The rent test is the limiting factor |
| Wait on score | Moves a free-and-clear rental from 70% to 75% LTV at 740 | You are within reach of 740 |
| Different collateral | Use a second rental with less debt | Another property has more equity |
A cash-out refinance resets the whole loan, while the line leaves the first mortgage untouched.
Using the money matters too. The new property’s coverage reads its own rent against its own payment, so a line secured by a different rental does not enter that ratio. The purchase lender still has to accept borrowed funds for the down payment, so confirm that before you commit.
The line is never closed together with a purchase, and it is never a third lien. It is not offered on a primary residence or second home.
Where the Complete Picture Lives
Across the wholesale network, programs differ on leverage, score floors and valuation. The figures above are one select program’s ceilings and floors, never offers. For the wider picture of how these loans work, see the complete DSCR loans guide. Qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines, credit approval and property review.
Frequently Asked Questions
Does a 735 score let me borrow more than a 720 score would?
Not on a second lien. Every score from 720 up falls into the same 70% CLTV cell, so the line is set by value, the first-mortgage balance, the rent test and the $500,000 cap. On a free-and-clear rental, 740 opens the 75% LTV band, so 735 sits just under it. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Can my LLC hold title to the rental?
Yes, 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. The property must be an investment property, since the line is never offered on an owner-occupied home.
How long do I have to own the rental before I can apply?
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 are checked at the file level, subject to underwriting.
Does the rent test use my drawn balance or the whole line?
The whole line. The qualifying payment is fully amortizing on the entire credit limit at a stressed start rate, so an undrawn balance still counts. The minimum is 1.10x, and the lender’s calculation governs the exact result.
Can I use this line to buy my next rental in cash?
You can use the funds toward a down payment, since the line is secured by a different rental. The purchase lender must accept borrowed funds, and the new property’s coverage reads its own rent against its own payment.
