The Quick Read: It depends on equity, door by door, because each line sits on one property. On a second lien behind a first mortgage on an investment property, combined leverage tops out at 70% CLTV for scores of 720 or better, with lines up to $500,000, subject to underwriting.
- Equity sets the ceiling: value times 70% CLTV, minus the first mortgage, on each rental separately.
- Rent sets a second ceiling: the property must cover the qualifying payment at 1.10x on a stress test of the whole line.
- A rental with no mortgage can take a first-lien line at up to 75% LTV (740 or better), with a lower ceiling on bigger lines.
- Three doors means up to three separate files, not one pooled equity number.
- Each file is subject to lender guidelines, credit approval and property review.
The Formula Behind Every Line Size
The line size comes from equity, not from rent. Take the property’s value and multiply it by the combined loan-to-value cap. Subtract every lien already recorded against that property. The result is the most the line can be, and the program’s dollar cap can lower it further.
Lendmire is a broker, and across its wholesale network this product is a standalone second lien behind the first mortgage you keep. It can also be a standalone first lien on a rental with no mortgage at all. The rent qualifies the file. The program does not calculate your personal income, and it does not ask for tax returns, W-2s or pay stubs. The LLC can stay on title, subject to lender program eligibility.
Combined loan-to-value, or CLTV, counts the first mortgage balance plus the new line, divided by value. Yahoo Finance’s CLTV explainer describes the same idea: total debt against the home’s value, with the amount you plan to borrow included. Paying down debt, borrowing less or rising value all lower the ratio.
For a second lien on an investment property, the ceiling is 70% CLTV at a 720 credit score or better. Lines run from $50,000 to $500,000. Below 720 there is no second-lien option on this program. Programs change, and every file is underwritten on its own facts. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
One Pool or Three Lines?
Three single-family rentals mean three liens, and equity is measured on each one. A strong door does not subsidize a weak one. A property with plenty of equity cannot lend its room to a property that is heavily mortgaged.
The practical result is simple. Size each door with the formula above. The three-door total is the sum of up to three separate lines, and each line needs its own valuation, its own title work and its own coverage test.
Here is a modeled example using only percentages of value:
| Door | First mortgage | Room under 70% CLTV |
|---|---|---|
| Door A | 40% of value | 30% of value |
| Door B | 55% of value | 15% of value |
| Door C | 68% of value | 2% of value |
Door A carries most of the borrowing power. Door B is workable if its value is high enough to produce a line above the $50,000 minimum. Door C is effectively out. A 2% sliver is too thin for the minimum line size on almost any property.
The same math shows the flip point. If the first mortgage is 55% of value, a 70% CLTV cap leaves about 15% of value. At 65% there is only 5% left. At 70% or more, nothing is left. A landlord whose doors all sit near the cap is not a candidate for a second lien, and a cash-out refinance may be the better tool. That comparison comes up again below.
There is also a program limit on total exposure. A borrower can have at most 5 loans or $2,500,000 with the program. Three doors fit comfortably inside that, but a landlord with a larger book should count what already sits with it.
What If “Three Doors” Means One Triplex?
A three-unit building is one property and one lien. It gets one line, sized at up to 70% CLTV of the whole building’s value when a first mortgage stays in place. It does not get three lines.
Rent works differently here too. The coverage test uses the building’s rent, and a lease must be in place. A two-to-four-unit property may have at most 1 vacant unit. A triplex with one empty unit can still be reviewed. A triplex with two empty units cannot.
The tradeoff is concentration. Three single-family doors give you three separate pools of equity and three separate collateral risks. A triplex puts everything on one parcel. That is simpler to manage and it can be cheaper to carry, but a single bad inspection or valuation affects the whole line.
The Second Ceiling: Rent Coverage
Even when the equity is there, rent has to cover the line. The minimum DSCR is 1.10x. That is gross monthly rent divided by a qualifying payment. The qualifying payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It is a stress test, and it assumes you draw everything. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Two details matter. First, the qualifying payment is principal and interest only. Taxes and insurance are not part of it. Second, rent is the lesser of the appraiser’s Form 1007 market rent and the lease, unless three months of rent receipts support a lease above market.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. That treatment decides how much cushion the rent leaves, and the lender’s own calculation governs.
Which ceiling binds first depends on the property. A high-value rental with modest rent tends to hit the coverage test before the equity test. A low-value rental with strong rent and a small first mortgage tends to hit the dollar cap or the minimum line first. Run both numbers on every door before you pay for an application.
Broker experience across the network shows the practical pattern. Lenders size to the weaker of the two tests, and the coverage test is calculated on the full limit, not the amount you plan to draw. Asking for a smaller line can improve the coverage number even when the equity room is large.
A Paid-Off Door Plays by Different Rules
A rental with no mortgage can take a standalone first-lien line. This is the cleanest structure for a landlord with a free-and-clear door. The leverage is written as loan-to-value, not combined, because there is no other lien.
- 740 or better: up to 75% LTV on a first lien, on lines up to $500,000.
- 700 to 739: up to 70% LTV on a first lien, on lines up to $500,000.
- Lines above $500,000, up to $1,000,000: 65% LTV on a first lien at 720 or better. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
The first-lien credit floor is 700. A rental with a mortgage cannot take a first lien. A borrower who keeps a first mortgage can only take a second lien, and that route requires a 720. A borrower at 700 to 719 with a mortgage on the door is therefore stuck on this lane, and the 700 floor only helps when the rental is unencumbered.
If a free-and-clear door could support a line above $500,000, the 65% ceiling means the bigger line gets less leverage than a smaller one. The larger the ask, the more equity the program expects you to keep. Some landlords find the $500,000 line at 75% serves them better than stretching for the larger tier.
The Other Gates: Credit, Valuation, Seasoning, Property
Passing the ceilings is not enough. Several other conditions apply.
Credit and history. The program wants 720 on a second lien and 700 on a first lien, using the lender’s own credit report. It also looks for no 30-day late payment on a mortgage in the last 12 months. After a bankruptcy, foreclosure, short sale or deed-in-lieu, 48 months must pass. No reserves and no cash to close are required, subject to underwriting.
Valuation. For lines to $400,000, the lender uses an automated valuation with a confidence score of 85 or better, paired with a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal on Form 1004, 1073 or 1025. Appraisal waivers are not accepted. A declining-market flag lowers the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower.
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).
Property type. Single-family homes, PUDs, townhomes, two-to-four-unit buildings, and warrantable and non-warrantable condominiums are eligible. Lots up to 10 acres are eligible too. Rural-designated property is out. So are row homes, condotels, mixed-use and commercial property, leaseholds, land trusts, age-restricted communities, modular and log homes, and any property listed for sale in the prior 2 months or carrying a solar lien. If one of your three doors is a row home, it needs a different loan.
Borrowers. U.S. citizens, permanent residents and non-permanent residents with a Social Security number qualify. Foreign nationals and ITIN borrowers do not.
Where it is offered. The program is available in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
How the Line Draws and Repays
You do not get a blank checkbook. 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 up front. Later draws must be at least $5,000 each.
The line has a 5-year interest-only draw period on the drawn balance. Then a 25-year fully amortizing repayment period begins, for a 30-year maturity. The rate is variable.
A line like this works best for a landlord who has a use for most of the money on day one: a down payment on another rental, a major renovation, or paying off higher-cost debt. It works less well as a standby reserve, because most of the line is drawn and interest-bearing from the start. The CFPB’s explainer on home equity lines describes the general structure: a revolving line with a draw period followed by repayment, and a risk that falling behind could cost you the property.
HELOC, Cash-Out or a Bank Line?
The right tool depends on what the landlord wants to protect. Here is how three common options compare:
| Factor | DSCR HELOC (second lien) | DSCR cash-out refinance | Bank HELOC on personal income |
|---|---|---|---|
| First mortgage | Stays in place | Replaced by one new loan | Stays in place |
| Qualified on | Rent coverage | Mainly the rent | Personal income and debts |
| Leverage | Up to 70% CLTV | Generally higher | Set by that bank |
| Entity title | LLC allowed, per program terms | Often allowed | Often personal title |
If the current first mortgage is one you would hate to give up, a second lien keeps it intact. If your personal income file is messy or your debts are heavy, property-rent-based lender review may be cleaner. Self-employed landlords with several properties often fit that profile.
Flip the case when the first mortgage is already near 70% of value. A second lien has no room, and a cash-out refinance, which generally reaches higher leverage and larger loan amounts, may be the only way to reach the equity. Flip it again if you need more than $500,000 against a single door. This line has no higher tier on a second lien. The complete DSCR loans guide covers the cash-out side.
A bank HELOC on personal income is a different product with different rules. Some banks lend on rentals and many do not. This program does not depend on that.
Risks Worth Sizing
Variable-rate exposure is the biggest one. The CFPB booklet on home equity lines notes that if you sell the home you are generally required to pay off the line in full. For a landlord, that means selling a door requires paying off the line on that door at the closing table. The interest-only draw period also makes payments look smaller than they will be when repayment begins, so test cash flow against the later payment.
Stacking debt on rental equity can also raise the risk across the whole portfolio. Three lines on three doors means three liens, and a vacancy on one property still has to be carried. Keep a cushion above the 1.10x minimum for your own planning.
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.

Before You Apply: A Self-Check
1. Write down the value, first-mortgage balance and vesting for each door. 2. Compute value times 70% minus the first mortgage for each door with a mortgage. 3. For any paid-off door, check your score against the 740 and 700 tiers. 4. Confirm a lease is in place and no more than 1 unit is vacant on a two-to-four-unit building. 5. Confirm the property is not on the excluded list, such as a row home or rural-designated property. 6. Check both six-month seasoning clocks on every door. 7. Confirm with the lender whether the first mortgage allows a second lien. 8. Count your existing loans against the 5-loan, $2,500,000 exposure limit.
If a door fails step 2 or 6, take it off the list and size the rest.
Frequently Asked Questions
Can I get one line against all three rentals?
No. Each line is a lien on one property, so three doors means up to three separate files. Each door is sized by its own value and its own mortgage balance. A three-unit building is the exception because it is a single property with a single line.
Does the first mortgage have to be a DSCR loan?
No. The first mortgage you keep does not have to come from any particular program, but its terms must allow a second lien. A second-lien line also needs a 720 credit score and combined leverage at or under 70% CLTV on an investment property. Confirm the first loan’s terms before you apply. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Can my LLC be the borrower?
Yes, on investment property, subject to program terms. The LLC members sign as guarantors, and a title holder who is not a borrower 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.
How soon after buying 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). A newly purchased door has to age before it can be tapped.
Why would a line come back smaller than my equity suggests?
The rent test runs on the full credit limit, so a high limit can fail 1.10x even when equity is ample. The dollar caps and the 5-point declining-market adjustment can trim it further. Requesting a smaller line often helps the coverage number.
