The Quick Read: Usually up to 70% combined loan-to-value (CLTV) on a rental, minus the balance on your first mortgage, with lines from $50,000 to $500,000, when your credit score is 720 or better and the rent covers a stress payment on the whole line at 1.10x or better, subject to underwriting.
- The formula: value times 70%, minus every lien already on the property. What is left is your equity room.
- The size window: a second-lien line runs from $50,000 to $500,000 through select programs. The smaller of your equity room and your rent coverage sets the real limit.
- The score: 720 or better. Below 720, this program has no second-lien option.
- The counting rule: the full line limit counts toward leverage, not just the part you draw.
- The three gates: your first mortgage must allow a second lien, title must fit the program, and rent must cover the line.
Here is the plain version. A DSCR HELOC is a home equity line of credit on a rental, qualified on the property’s rent instead of your personal income. It sits behind the first mortgage as a second lien. Your first loan stays exactly as it is. The rest of this piece shows how the limit is built, why real equity can still leave little room, and what to do when the numbers fall short.
What a DSCR HELOC Is (and What It Is Not)
A DSCR HELOC is a revolving line secured by a rental you already own. DSCR stands for debt service coverage ratio, which is the property’s rent divided by the payment the lender uses to test it. The line qualifies primarily on property-level rental income covering that payment, subject to lender guidelines. No traditional personal-income documentation, W-2s, pay stubs or personal debt-to-income ratio come into it.
Across Lendmire’s wholesale network, this program is written one of two ways. It is a standalone second lien behind a first mortgage you keep. Or it is a standalone first lien on a rental with no mortgage at all. You are keeping a DSCR first mortgage, so you are in the first group.
A few boundaries matter right away:
- It is for non-owner-occupied rentals only, one to four units. It is never a line on your own home or a second home.
- It is never closed together with a purchase.
- It is never a third lien. If a second lien already exists, there is no room for another.
- DSCR loans are designed for investment properties. Because they are business-purpose loans, they are reviewed differently from a standard owner-occupied mortgage.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is the broker. It arranges the line through a wholesale lender, and the lender underwrites and decides.
How Much Can You Borrow? The Sizing Formula
Your equity ceiling is the rental’s value times the combined cap, minus every lien already on the property. On a second lien, the cap is 70% CLTV at a 720 score or better, and lines run from $50,000 to $500,000, subject to underwriting. Whatever is left after your first mortgage is your room.
CLTV counts every loan against the same value: the first mortgage, any second, any line, and any other recorded debt. In Lendmire’s network, the number is the first mortgage balance plus the full new line, divided by value. AdviceOnly’s CLTV glossary describes the same idea. Every lien is counted, and an open-end line is measured by its credit limit.
That last point trips people up. You might plan to draw only a little. The leverage test still counts the entire limit. A line sized at $200,000 counts as $200,000 even if you plan to leave most of it alone. (On this program, at least 80% of the line is drawn at closing anyway, so the whole limit is rarely a hypothetical.)
Here is how room shrinks as the first mortgage grows. These are percentages of value, because the dollars depend on your property.
| First mortgage as % of value | Room under 70% CLTV | What it means |
|---|---|---|
| 50% | 20 points | Wide room for a line |
| 60% | 10 points | Room, but check the line minimum |
| 65% | 5 points | Likely too thin for the minimum line |
| 70% or more | None | No second-lien room |
Read the table with the line minimum in mind. The smallest line is $50,000. If your room is worth less than that in dollars, there is nothing to write. On a modest-value rental, 10 points of room can fall short of the floor. On a high-value rental, the same 10 points can be plenty.
This is why a landlord can have real equity and still be stuck. Say you own a rental with a first mortgage at 65% of value. You have 35% equity on paper. But the program stops at 70% combined, so only 5 points are usable.
Three Ceilings, and the Lowest One Wins
The equity cap is only one limit. Three ceilings apply at once, and the lowest controls.
The equity ceiling. This is value times 70%, minus your first mortgage, as shown above.
The line-size ceiling. A second-lien line tops out at $500,000. A rental worth a lot with a small first mortgage still cannot get a bigger line from this program. If you need more than that, a cash-out refinance is the usual alternative.
The rent ceiling. The rent must cover a stress payment on the entire credit limit at 1.10x or better. The stress payment is a fully amortizing payment on the whole line, figured at a rate set above the starting rate. It covers principal and interest. Taxes and insurance are not part of it.
The rent used 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. A two-to-four-unit property may have at most one vacant unit.
A bigger line means a bigger stress payment, so coverage falls as the line grows. A rental can have enough equity for $300,000 and enough rent for only a smaller line. Rent, not equity, then sets your limit.
One question the rent test raises is whether the first mortgage payment is added to the qualifying payment on a second lien. That depends on the lender’s own coverage calculation, so confirm on your file how the lender treats it. Do not assume your first loan’s payment is ignored. Do not assume it is stacked on top, either. Ask before you size the line around either answer.
Gate One: Will Your First Mortgage Allow a Second Lien?
Your DSCR first mortgage is a contract, and that contract may say something about junior liens. Check this before you pay for an appraisal.
Pull the note and the deed of trust or mortgage. Look for language about additional liens, junior financing, or transfers of the property. Those clauses decide whether the first lender needs to be told, or must consent. Some loan documents are silent, and some are strict.
Then put the question to the servicer in writing. Ask whether a recorded second lien is permitted, whether consent is required, and whether a second lien affects the first loan’s terms. Keep the reply with your file. A written answer is worth more than a phone call you cannot prove.
If you already have a first mortgage you like, the whole point is to leave it alone. A line that triggers a default on that loan defeats the purpose.
Gate Two: Title and Vesting
Many investors hold rentals in an LLC. Vesting in your LLC is allowed on this program, for investment property only, subject to program terms. The LLC members sign as guarantors. If the title holder is not a borrower on the line, that holder signs a non-borrowing owner acknowledgment and the security instrument.
The borrowers on the line do not have to be the borrowers on the first mortgage. That helps when the first loan was written in one name and ownership has since changed. But any change to title can raise its own question with your first lender. Check the first loan’s transfer language before moving a deed.
Not every home equity product treats LLCs the same way. Lendmire also places an income-based investment HELOC, which is reviewed on the borrower’s personal profile and wants title in the individual’s name or a revocable trust. That is a different product with different rules. Do not blend the two.
Gate Three: Your Score, the Property and the File
Credit. A second lien needs a 720 score or better, on the lender’s own report. There should be no 30-day mortgage late in the last 12 months. The program wants 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required, subject to underwriting.
If your score is 700 to 719 and you keep a first mortgage, this program has no second-lien option. The common move is a DSCR cash-out refinance, which replaces the first mortgage. That trade-off is covered in Lendmire’s piece DSCR HELOC vs DSCR Cash-Out Refinance Behind a DSCR First Mortgage You Want to Keep.
Value. Lines up to $400,000 use an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal. Appraisal waivers are not accepted. The value you get drives every number above, so a low valuation shrinks your room.
Property. Single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums are eligible. Lots up to 10 acres work too. These are outside the program:
- Rural-designated property
- Row homes
- Condotels
- Commercial or agricultural property
- Leaseholds and land trusts
- Age-restricted communities and hobby farms
- Modular and log homes
- Land contracts and mixed-use
- A property listed for sale in the prior 2 months
- A property with a solar lien
A declining-market flag lowers the leverage ceiling. 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. NerdWallet notes that some lenders restrict investment-property HELOCs based on location and whether you rent the home all year.
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).
Borrowers. U.S. 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.
How the Line Works After You Close
The line has a 5-year draw period, interest-only on the drawn balance. After that comes a 25-year fully amortizing repayment period, with a 30-year maturity. The rate is variable. The rate and the pricing terms come with the lender’s disclosures.
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.
So available credit is not free credit. Most of the limit becomes a drawn balance on day one, and the interest-only payment on it starts then. Size the line for the cash you need, not for a cushion you hope to leave untouched. A general HELOC booklet from the Consumer Financial Protection Bureau describes the same shape in broad terms: a draw period, then a repayment period. It is written for owner-occupied homes, so use it for mechanics only.
DSCR Line vs. Cash-Out vs. Bank HELOC
The right tool depends on what you want to protect. The table compares structure, not pricing.
| Factor | DSCR HELOC | DSCR cash-out refinance | Bank HELOC |
|---|---|---|---|
| First mortgage | Stays in place | Replaced | Stays in place |
| Lien added | Second lien | None; one new first | Second lien |
| Who is underwritten | The rental’s rent | The rental’s rent | Usually you, personally |
| LLC title | Allowed, subject to program terms | Depends on program | Often not offered |
| Availability | 15 of Lendmire’s 16 licensed states | Wider footprint | Not offered by all lenders |
The bank column reflects what NerdWallet reports: a HELOC on an investment property is not offered by all lenders, and the requirements are strict. NerdWallet also cites at least 20% equity as a market figure. In this network, the second-lien cap is 70% CLTV at 720 or better, which means at least 30% stays untouched across all liens.
A cash-out refinance swaps your first mortgage for a bigger one. A line adds a payment on top of the one you have. If your first loan is one you want to keep, the line is the cleaner tool. If your first loan is not that attractive, the cash-out may do more.
Also think about the exit. A second lien has to be cleared before a cash-out refinance on that same property. If you plan to refinance the first mortgage later, the line gets paid off or dealt with first.
When the Numbers Fall Short
If the formula leaves you with too little room, you have four honest options:
1. Shrink the line. If your room covers the $50,000 minimum, a smaller line fits. If it does not, this path is closed for now.
2. Wait for paydown or value. Each point of first-mortgage paydown opens more room under the 70% cap. Added value may support a higher appraised value, depending on comps and underwriter review, which could also open more room. A rental held longer may reach the line minimum.
3. Improve the coverage. If rent is the limit, a stronger lease or three months of receipts supporting a lease above market may help. Whether it works depends on the lender.
4. Switch to a cash-out. If your score is under 720, or you need more than $500,000, a DSCR cash-out refinance replaces the first mortgage rather than adding behind it.
Using the line as a down payment on the next rental is a common plan. The purchase lender makes its own decision on borrowed down-payment funds, and the new property still has to cover its own payment. Check that before you draw.
On a rental with no mortgage, the first-lien path uses different numbers. A first-lien line reaches 75% LTV at 740 or better, and 70% LTV from 700 to 739, on lines up to $500,000. Lines above $500,000, up to $1,000,000, are capped at 65% LTV at 720 or better. That path is not open to you while you keep a first mortgage. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Key Terms Defined
DSCR (debt service coverage ratio): the rent divided by the qualifying payment. This program needs 1.10x or better on the whole line.
CLTV (combined loan-to-value): the first mortgage plus the full new line, divided by the property’s value.
Second lien: a loan recorded behind the first mortgage. If the property is sold or foreclosed, the first lien is paid first.
Stress payment: a fully amortizing payment on the entire credit limit, figured at a rate above the starting rate. It tests whether rent can carry the line.
Additional-lien covenant: language in a loan document that limits or conditions a junior lien on the property. Your first mortgage may carry one.
Subordination: an agreement that a lien sits behind another. It comes up when a first mortgage is refinanced later while a second lien stays in place.
Frequently Asked Questions
Does a DSCR HELOC change my first mortgage?
No. The first mortgage keeps its balance and terms, and the line is recorded as a separate second lien behind it. What the line can change is the combined picture: your combined leverage and your overall payment load. Whether your first loan’s documents allow a junior lien is a separate check, so ask the servicer in writing before you apply.
Can my LLC hold the line?
Yes, subject to program terms. Vesting in your LLC is allowed on investment property. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment. The answer is different for the income-based investment HELOC, which wants title in your own name or a revocable trust.
How long must I own the rental before I can open a 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). So a recent purchase or a recent refinance can both delay a file.
Do I need to show tax returns or personal income?
No. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The lender still documents the lease, the rent, your credit report and the property’s value. What it does not do is calculate your personal income or debt-to-income ratio.
What if I need more than $500,000?
A second-lien line stops at $500,000. For a larger amount, a DSCR cash-out refinance is the usual alternative, since it replaces the first mortgage instead of adding behind it.
