The Quick Read: The right line size is the smaller of two limits: the equity room left under the leverage cap, and the amount the rent can carry on a stress payment calculated across the whole credit limit, with both tested by the lender and subject to underwriting. The equity limit comes from value and existing liens. The rent limit comes from the lease, the appraisal and the size of the line itself.
- On a second lien, combined loan-to-value (CLTV) tops out at 70% with a 720 credit score, on lines up to $500,000.
- On a first lien with no mortgage, loan-to-value (LTV) reaches 75% at 740 or better, and drops to 65% on lines above $500,000.
- Rent must cover the stress payment at least 1.10 times, and the payment is figured on the entire limit, not just the drawn balance.
- At least 80% of the line is drawn at closing, so plan the line as a real borrowing amount, not a standby cushion. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

What Is a DSCR HELOC, Exactly?
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. There is no traditional personal-income documentation: no W-2s or pay stubs, and no personal debt-to-income calculation.
The label is loose. Across the market, people use “DSCR HELOC” for several different products, including cash-out refinances and closed-end second mortgages. The version described here is a true line. It is written as a standalone second lien behind the first mortgage you keep, or as a standalone first lien on a rental with no mortgage.
Three structural facts shape every sizing decision:
- It is never closed together with a purchase.
- It is never a third lien.
- It is never placed on your own home or a second home.
Your LLC can hold title, subject to lender program eligibility. The members sign as guarantors. A title holder who is not a borrower signs an acknowledgment and the security instrument.
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.
Lendmire is a broker. It arranges this line through a wholesale lender in its network, and the program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Everything below is subject to underwriting, and the figures are ceilings and floors, not offers.
Key Terms Defined
DSCR (debt service coverage ratio): gross monthly rent divided by the qualifying payment. A result of 1.10 means the rent is 110% of that payment.
CLTV (combined loan-to-value): every lien on the property, including the new line, divided by the property’s value. Yahoo Finance’s CLTV explainer notes that CLTV falls when you pay down debt, take a smaller loan or the value rises.
LTV (loan-to-value): the same idea with one lien. On a first-lien line, there is no other mortgage, so LTV is the right label.
Stress payment: the payment the lender uses to test coverage. It is a fully amortizing payment on the entire limit, at a rate 2 percentage points above the line’s starting rate. You never pay it during the draw period. It only sets the size of the test.
Draw period: the first 5 years, when you pay interest only on what you have drawn. The 25-year repayment period follows.
Lien position: your place in line if the property is sold to pay debts. A second lien sits behind the first mortgage.
What Does the Lender Test, and in What Order?
The lender checks gates in a fixed order. Each one can cap or kill the line, so knowing the order tells you where to look first.
1. Property. One-to-four units, owned and rented, with a lease in place. A two-to-four-unit property may have at most 1 vacant unit. Rural-designated property, row homes, condotels, leaseholds, land trusts, mixed-use and a few other types are outside this lane.
2. Lien position. A second lien needs a first mortgage that stays in place. A first lien needs a rental with no mortgage.
3. Credit. A 720 minimum on a second lien and 700 on a first lien. The lender looks for no 30-day mortgage late in the last 12 months. It also wants 48 months since any bankruptcy, foreclosure, short sale or deed-in-lieu.
4. Coverage. Rent must reach at least 1.10x of the qualifying payment on the full limit.
5. Leverage. CLTV or LTV must fit the tier for your credit score and line size.
6. Valuation. An automated valuation or a full interior appraisal, depending on line size.
7. 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 who qualify are U.S. citizens, permanent residents and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. The program requires no reserves and no cash to close.
Sizing Step One: The Equity Ceiling
The equity ceiling is value times the leverage cap, minus every lien already on the property. That is the most the equity can support, whatever the rent says.
On a second lien, the cap is 70% CLTV at a 720 score or better, on lines up to $500,000. Below 720 there is no second-lien option. Work in percentages of value and the arithmetic stays simple:
| First mortgage (% of value) | Room for the line at 70% CLTV |
|---|---|
| 40% | 30% of value |
| 55% | 15% of value |
| 65% | 5% of value |
| 70% or more | None |
Two quirks catch investors.
Equity on paper is not equity available. Owning 30% equity sounds like room. With a first mortgage at 70% of value, a second lien has none, because the cap applies to total liens. Usable equity is always smaller than total equity.
Leftover room can be too small to use. Lines start at $50,000. On a lower-value rental with a first mortgage near the cap, the remaining room can fall under that floor. Then there is no line to write.
On a first lien, the tiers work differently. A rental with no mortgage can reach 75% LTV at a 740 score or better, and 70% LTV from 700 to 739, on lines up to $500,000. Lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. Write these as LTV, not CLTV, because no other lien exists. Only a rental with no mortgage can take a first-lien line. An owner who keeps a first mortgage takes a second lien. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Value moves the answer. Say your first mortgage sits at 55% of value and you take a line that brings combined debt to 70%. If the valuation later comes in 10% lower, that same debt is about 78% of the new value. A declining-market flag on the property can also lower the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
Hazard insurance must cover both liens, with flood coverage where required. Note that every lien counts, so an old second or an unreleased line reduces the room. This program does not write a third lien.
Sizing Step Two: The Rent Ceiling
The rent ceiling is the largest line whose stress payment the rent still covers at 1.10x. Because that payment is figured on the entire credit limit, a bigger limit means a bigger test payment and a lower ratio.
Start with the rent that counts. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The appraiser documents market rent on Form 1007.
The qualifying payment is principal and interest on the full line. Taxes and insurance are not part of it. On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation, since the lender’s own calculation governs.
Here is the useful part. The stress payment rises roughly in proportion to the limit. So you can work backward from the ratio:
- Say a requested limit tests at 1.00x. You need 1.10x. Shrinking the limit by about 9% gets there.
- A limit that tests at 0.95x needs to shrink by about 14%.
- A limit already above 1.10x has no rent problem at all, so equity decides.
Drawing less does not rescue a thin ratio, because the test uses the whole limit. Also, at least 80% of the line is drawn at closing, so the line size is the real choice you are making.
Which Limit Wins? A Sizing Worksheet
Run both ceilings and take the lower one. Do this on each property separately, because equity does not pool across rentals.
1. Value. Use a realistic value, then think about a drop of 10% as a stress case.
2. Equity ceiling. Value times 70% for a second lien, minus the first-mortgage balance. For a no-mortgage rental, use the first-lien tier your score allows.
3. Rent ceiling. Start from the requested limit. Check the coverage ratio, then scale the limit down until the ratio reaches 1.10x.
4. Take the smaller number. That is your maximum.
5. Check the floors. The line must be at least $50,000, and the closing draw is never less than $50,000.
6. Check your exposure. The program allows at most 5 loans or $2,500,000 per borrower.
If equity is the binding limit, the fix is more equity: pay down debt, wait for value, or consider a first lien if the property has no mortgage. If rent is the binding limit, the fix is a smaller line or stronger documented rent.
What Does the Valuation Do to Your Number?
Lines up to $400,000 use either an automated valuation with a confidence score of 85 or better and a property inspection report, or a full interior appraisal. Lines above $400,000 require a full interior appraisal (Form 1004, 1073 or 1025). Appraisal waivers are not accepted.
Improvements may support a higher appraised value, depending on comps and underwriter review. Plan around that number, not around your own estimate. If the value comes in low, both ceilings can shrink at once, since equity room falls and market rent may follow.
Why a Bigger Line Is Not a Better Line
The maximum is a ceiling, not a target. Three things make the largest possible line a risky choice.
The rate is variable. The CFPB notes that HELOCs usually carry a variable rate, so payments can change from month to month. A line sized to the very edge of the rent test leaves little cushion if rent softens or a unit sits vacant.
The payment steps up. You pay interest only on the drawn balance for 5 years. After that, the 25-year amortizing repayment period begins, and principal joins the payment. A line that feels easy in year two can feel tight in year six. Run your own cash flow at the amortizing payment before you commit.
The closing draw is large. With at least 80% of the line drawn at closing, you begin paying interest on most of it right away. Later draws are at least $5,000 each, so the unused portion is a small reserve. This is not a standby line for rainy days.
Use of proceeds matters too. Putting the money into a down payment on the next rental or into improvements that raise rent can turn the borrowing into income. Using it to cover negative cash flow is the opposite. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Here is a judgment call worth weighing. Someone with a first mortgage at a modest share of value could take the full equity ceiling. But the more prudent play is often a line sized with a 10% valuation drop and a rent dip in mind. The smaller line costs you some firepower and buys a lot of safety.
When the Numbers Do Not Fit
Not every rental fits this lane. Here are the common breaks and what usually follows.
- The first mortgage is already at the cap. There is no second-lien room. A DSCR cash-out refinance replaces the first mortgage with a new loan, which is a different product with its own rules.
- Credit is 700 to 719 on a rental with a first mortgage. A second lien needs 720. The first-lien tiers do not apply because the property is not mortgage-free.
- Rent is too thin. Shrink the line, document market rent more strongly, or look at another structure.
- The property type is excluded. Rural-designated property, row homes, condotels, leaseholds, land trusts, a property listed for sale in the prior 2 months, and a property with a solar lien are all outside this lane.
- You bought or refinanced recently. The seasoning rule above applies.
A side-by-side look helps frame the choice:
| Feature | DSCR HELOC | Income-qualified HELOC from a bank | DSCR cash-out refinance |
|---|---|---|---|
| Reviewed on | Rental income | Personal income and DTI | Rental income |
| First mortgage | Stays in place | Stays in place | Replaced |
| Structure | Revolving line | Revolving line | Closed-end loan |
| LLC title | Allowed, per program terms | Often limited | Often allowed |
The middle column describes that product’s rules, not this program’s. NerdWallet reports that rental HELOCs from banks carry strict requirements and come from a smaller pool of lenders. It lists typical criteria of a 40% to 50% DTI and six months or more of reserves. This DSCR line, by contrast, has no DTI calculation and no reserve requirement, subject to underwriting. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Frequently Asked Questions
How much equity can I borrow with a DSCR HELOC?
It is the lower of two numbers. The equity limit is value times the leverage cap, minus existing liens, which means 70% CLTV on a second lien with a 720 score. The rent limit is the line size at which rent still covers the stress payment at 1.10x. Both are subject to underwriting.
Do I need tax returns or a debt-to-income ratio?
No. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The lender still reviews the lease, the credit report and the valuation. Those are documented, and the personal income file stays closed.
How soon after buying a rental can I 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).
Can I borrow less than the maximum, or draw only a little?
You can request a smaller line, and it helps coverage. You cannot plan to draw only a little, though, because at least 80% of the line is drawn at closing. Later draws must be at least $5,000.
Can my LLC hold the property?
Yes, subject to lender program eligibility. The members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment and the security instrument. The borrowers on the line need not match the borrowers on the first mortgage.
