The Quick Read: It depends on equity first and rent second: through select programs, the line equals the property’s value times the combined loan-to-value ceiling, minus every lien already recorded, and then the rent must cover a stress payment on the whole line, so the smaller of those two limits sets your number, up to $500,000 on a second lien. Equity decides how big the line can be. Rent decides whether the line qualifies at all. Every figure below is a ceiling or floor from select wholesale programs, subject to underwriting, and never an offer.
- A second lien behind your existing first mortgage reaches 70% combined loan-to-value (CLTV) at a 720 credit score or better, on lines from $50,000 to $500,000.
- A first lien on a rental with no mortgage reaches 75% loan-to-value (LTV) at 740 or better, 70% from 700 to 739, and 65% on lines above $500,000, up to $1,000,000.
- The rent must clear a 1.10x coverage test calculated on the entire credit limit, not just the part you draw.
- At least 80% of the line is drawn at closing, so this works as a funded line you can re-borrow against, not an untouched standby account. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
The Sizing Formula: Value, Ceiling, Liens
The maximum line is a subtraction problem. Multiply the property’s value by the lender’s ceiling, then subtract every recorded lien. What remains is the most equity room the lender will let you use. A dollar cap and the rent test can shrink that number further, but they cannot raise it.
NerdWallet notes that rental properties get tighter limits than primary homes, with fewer lenders willing to offer a line. Across the select programs Lendmire places files with, a second lien on a rental tops out at 70% CLTV, which is a conservative ceiling.
The word “combined” matters. CLTV adds your first mortgage balance and the new line together, then divides by the value. A first mortgage that already uses most of the allowed leverage leaves little room. A first mortgage that has paid down, or a property that has appreciated, leaves more.
Second Lien or First Lien: Where the Percentages Differ
Lien position changes the leverage table. A borrower who keeps a first mortgage can only take a second lien. A first lien exists only on a rental with no mortgage at all. Neither is ever closed together with a purchase, and neither can be a third lien.
| Factor | Second lien | First lien |
|---|---|---|
| Fits when | You keep a first mortgage | The rental has no mortgage |
| Top leverage | 70% CLTV at 720+ | 75% LTV at 740+ |
| Mid tier | None below 720 | 70% LTV at 700-739 |
| Line size | $50,000 to $500,000 | To $500,000; to $1,000,000 at 65% LTV |
| Credit floor | 720 | 700 |
Two details trip people up. A first-lien line above $500,000 carries a 65% LTV ceiling at 720 or better, so the biggest lines get the least leverage. And a borrower with a 700-to-719 score and a first mortgage is not blocked by lien position. The second-lien tier simply starts at 720. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
A declining-market flag on the property lowers the ceiling by 5 points. That is a lender call on the property, not something you control.
How Rent Coverage Limits the Line
Rent does not size the line, but it can cap it. The program qualifies the rental on its income: no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines. Market surveys report that bank-style investment-property lines typically test personal debt-to-income between 40% and 50%, per NerdWallet. This program takes no personal debt-to-income ratio, and the property carries the test.
The test is a debt service coverage ratio (DSCR) of at least 1.10x. You divide gross monthly rent by a qualifying payment. That payment is a fully amortizing principal-and-interest payment on the entire credit limit, run at the start rate plus a cushion of 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 in place is required.
Here is the part that surprises first-timers. The stress payment covers the whole limit, so asking for a bigger line raises the payment the rent has to cover. A rental with plenty of equity room can still be rent-limited, and the lender sizes the line down until coverage clears. Whether the first-mortgage payment also enters the coverage calculation on a second lien is a file-level question. Confirm how the lender treats it before you count on a number. The lender’s own calculation governs.
Three Sizing Scenarios in Percentages
These are illustrative and expressed as shares of value. The lender’s calculation governs.
Equity-limited second lien. Say your first mortgage equals 55% of the rental’s value, and your score is 720 or better. The 70% CLTV ceiling leaves 15% of value for the line. If that works out below $50,000, no line is available. If it clears the floor, rent coverage is the next test.
Roomier second lien. Now say the first mortgage equals 40% of value. The ceiling leaves 30% of value. On a modest property, equity is the binding limit. On a high-value rental, the $500,000 program ceiling can bind before equity does.
Rent-limited first lien. Picture a rental with no mortgage and a 740 score. The ceiling is 75% LTV, but the stress payment on a line that large may push coverage under 1.10x. The lender then sizes the line down to the point where rent clears the test. In that case, rent, not equity, is your limit. At 700 to 739 the ceiling drops to 70% LTV, and the same logic applies. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
The practical method is to find the equity limit, find the coverage limit, then check the floors and caps. The smaller number wins.
What the File Needs
Valuation depends on line size. Lines 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 require a full interior appraisal. Appraisal waivers are not accepted.
Credit has clear lines too. The score minimum is 720 on a second lien and 700 on a first lien, using the lender’s own report. There can be no 30-day mortgage late in the last 12 months. There must be 48 months since any bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required, subject to lender guidelines.
On time in the property, two clocks apply, and both are measured in six-month blocks. 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).
Property type matters more than many investors expect. Eligible: single-family, PUD, townhome, two-to-four units, condominiums (warrantable and non-warrantable) and lots up to 10 acres. Not eligible on this lane: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts, mixed-use, a property listed for sale in the prior 2 months, and a property with a solar lien.
Borrower limits also apply. 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.
The line can sit in an LLC, per lender program requirements. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. This product applies to a non-owner-occupied one-to-four-unit rental, never to your own home or a second home.
Draw Rules: Why a Line Is Not a Standby Fund
Many investors picture a line as a cushion that sits untouched. This program works differently. At least 80% of the line is drawn at closing, and the closing draw is never under $50,000. On the smallest lines, that means the whole line is drawn at closing. Later draws must be at least $5,000 each.
The draw period is 5 years of interest-only payments on the drawn balance. A 25-year fully amortizing repayment period follows, and the loan matures at 30 years. The rate is variable, so the payment moves with the balance and with the rate.
The CFPB’s plain-language HELOC explainer describes the general shape: a revolving line you can borrow against repeatedly, followed by a stretch where you repay and can no longer borrow. The agency’s HELOC brochure adds two cautions that apply to lines in general. A lender may reduce a line if the home’s value falls, and a sale of the property generally requires paying the line off in full. It also warns that lines secured by an owner-occupied home may prohibit renting the home out. That is why a landlord converting a primary residence is working with a different product than the one described here.
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.
Line, Closed-End Second, or Cash-Out Refinance?
The “DSCR HELOC” label gets attached to several structures. Ask which one you are being offered before you compare numbers.
| Factor | DSCR HELOC (this program) | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced by a new loan |
| How money arrives | Draw at closing, then later draws | One lump sum |
| Qualified on | Rent covering a stress payment | Rent covering the new payment |
| Best fit | Keep a first mortgage; re-borrow | Reset the whole loan |
NerdWallet describes a cash-out refinance as replacing your mortgage with a larger one and handing you the difference. That trade makes sense when you want to reset the whole loan, and it makes less sense when your existing first mortgage is worth keeping. A line leaves that first mortgage alone.
The line is the wrong tool in a few cases. It fails if you need a lump sum at once and cannot meet the closing draw rules. It also fails when the rental was bought or refinanced recently, or when the property type is on the excluded list. And a thin equity cushion may leave nothing above the $50,000 floor. In those cases a different structure may fit better.

Key Terms Defined
DSCR (debt service coverage ratio): the rent divided by the qualifying payment. Here it must be at least 1.10x.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
Second lien: a loan recorded behind your first mortgage, so the first lender gets repaid first.
Stress payment: the qualifying payment, which assumes the whole credit limit is drawn at a higher start rate than the line’s actual rate.
Draw period: the stretch during which you can borrow from the line. Here it is 5 years, interest-only on the drawn balance.
Frequently Asked Questions
Does higher rent get me a bigger line?
No. Higher rent helps you clear the 1.10x coverage test, but equity and the leverage ceiling set the size. Strong rent can keep a large request from being sized down. It cannot push the line above the CLTV or LTV ceiling, or above the program’s dollar cap.
Can my LLC hold the line?
Yes, subject to program terms. Vesting in the owner’s LLC is allowed on investment property. The members sign as guarantors. The borrowers on the line do not have to be the same people as the borrowers on your first mortgage.
I have a first mortgage and a 710 score. What are my options?
A second lien requires a 720 score, so this program does not fit as written. A first lien starts at a 700 score, but it exists only on a rental with no mortgage. Raising the score or paying off the first mortgage changes which tier you can reach, subject to lender guidelines.
Is it available where I live?
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Those states are Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia and Washington. 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.
Do I need a lease?
Yes, a lease in place is required. Multi-unit properties can have at most one vacant unit.
