The Quick Read: It depends on the equity left after every lien: on a second-lien line against a rental, the cap is 70% combined loan-to-value at a 720 credit score or better, so the most you can borrow is 70% of value, minus the first mortgage and any open-line balance still recorded, then limited to a $500,000 line. Rent has to clear the coverage test too, and that test can bind before equity does. Every figure here is subject to underwriting and lender guidelines. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
- The formula: value × 70% CLTV, minus all recorded liens, capped at $500,000 on a second lien.
- The rent test: a 1.10x minimum DSCR, measured against a stress payment on the entire credit limit.
- The line floor: lines start at $50,000, and at least 80% of the line is drawn at closing.
- The seller catch: a rental listed for sale in the prior 2 months is not eligible for a new line.
- Where it’s offered: 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
The phrase “sellers who still owe on an open line” can describe two different owners. One holds a rental with a drawn home equity line and wants more capital before deciding what to do with the property. The other is preparing to sell and wonders what the open balance does to the sale. This article covers both. The borrowing math comes first, because the same lien arithmetic drives each decision.
How Is the Maximum Line Calculated?
The maximum line is property value times the program’s combined cap, minus every lien already recorded against the property, then trimmed to the program’s line limit. A drawn balance on an old line counts as a lien in exactly the same way a first mortgage does.
That sizing logic is not unique to rental lending. The CFPB’s HELOC booklet explains that lenders set a credit limit as a percentage of appraised value and then subtract what is owed on the existing mortgage. A DSCR HELOC works the same way. It simply qualifies the line on the rental’s income instead of the owner’s.
A DSCR HELOC, as Lendmire places it, is a revolving line secured by a one-to-four-unit rental. It is written as a standalone second lien behind a first mortgage the owner keeps. On a rental with no mortgage, it is a standalone first lien. It is never a third lien. It is never a line on your own home. It is never closed together with a purchase.
Here is how the second-lien room shakes out. Treat the property value as 100% and the cap as 70% CLTV (720 credit score or better, investment property, subject to underwriting). Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
| First mortgage balance | Room under 70% CLTV | Read |
|---|---|---|
| 30% of value | 40% of value | Wide room |
| 40% of value | 30% of value | Healthy room |
| 55% of value | 15% of value | Thin; check the line floor |
| 65% of value | 5% of value | Rarely workable |
The line floor matters at the bottom of that table. Lines start at $50,000. If the leftover room works out below that, there is no line to write, no matter how the percentage looks.
Two more things can move the number. A declining-market flag on the property lowers the ceiling by 5 points. Philadelphia properties carry a ceiling 10 points lower. These adjustments apply on top of the 70% cap, subject to lender guidelines.
Why Rent Can Cap You Before Equity Does
The rent test sizes the line against the full credit limit, not the amount you draw. That makes a large line harder to qualify than its drawn balance suggests.
The program reviews the file on the rental’s income: no traditional personal-income documentation, W-2s, pay stubs, or personal income calculation, subject to lender guidelines. The test is a minimum DSCR of 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 a stress rate set above the starting rate. 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 building can have at most one vacant unit.
Picture an owner with plenty of equity room and a modest rent. Asking for the full line may push the coverage ratio below 1.10x. Asking for a smaller line may clear it. In that case, rent is the binding limit, not the 70% cap. Whether the first-mortgage payment joins the qualifying payment on a second lien is a detail to confirm on the file. The lender’s own coverage calculation governs, and the arithmetic here is illustrative only.
Most DSCR programs across a wholesale network size the line on rent first and equity second, or the reverse, depending on the property. Running both tests early shows which one is your ceiling.
What if the Open Line Is Already in Second Position?
If an existing line sits behind your first mortgage, it occupies the second-lien slot, and this program writes only a second lien. A new line cannot stack behind it as a third lien. The open balance counts against combined leverage either way.
Even a zero balance matters. The lien stays recorded until the lender files a release. Title will still show it. Whether the old line must be paid off and released before a new line is written is a file-level question. Confirm it before you plan around the new capital.
Sequence matters for the first mortgage too. A borrower who keeps a first mortgage can only take a second lien, and that needs a 720 score. Another point to check is whether the first mortgage’s own documents allow a junior lien at all. This is a broker’s practical checklist item, not a formality.
For readers still weighing options, Lendmire’s piece How to Qualify for a DSCR HELOC for Sellers Who Still Owe on an Open Line walks through the qualification side in more detail.
Can a Bank Line Do the Same Job?
Sometimes, but it is a different product with a different test. NerdWallet notes that fewer lenders offer a HELOC on an investment property, and that more than one appraisal may be required. Lines from large banks and other depository institutions typically test the owner’s personal debt-to-income and reserves. Those are that product’s rules, not this program’s.
The investor decision often comes down to profile. A salaried owner with one rental and clean personal income may find a bank line workable. A self-employed owner, or one with a portfolio held in an LLC, may find the personal-income file is the obstacle. For that investor, a line qualified on rent solves a real problem. Vesting in the owner’s LLC is allowed on this program (investment property only, subject to program terms). The members sign as guarantors. Many bank lines require the property in the owner’s own name.
Selling the Rental With an Open Line
A seller does not have to pay down an open line first. The balance is a payoff item at closing, like the first mortgage.
The title company requests a payoff statement and wires the funds from escrow. The lender then records a lien release. Because the line is tied to the collateral, it cannot follow you to the next property. As I Will Teach You To Be Rich explains, the line ends with the sale. That makes the stages before closing the part worth planning.
| Stage | New line on this property | Existing open line |
|---|---|---|
| Before listing | Possible if eligible | Counts against CLTV |
| Listed for sale | Not eligible (prior 2 months) | Lender may freeze or reduce |
| Under contract | Not available | Paid from proceeds |
| Closing | Not applicable | Payoff, then lien release |
The listing rule is the sharp edge. A rental listed for sale in the prior 2 months is outside this program. An owner who might sell should decide before the listing goes live, not after.
Existing lines have their own exposure. The CFPB’s HELOC booklet confirms that lenders may freeze or reduce a line under certain conditions. Then there is a practical risk: borrowing against a property you plan to sell. A drawn balance reduces net proceeds dollar for dollar. If the capital will not earn more than the balance costs to carry before the sale, drawing it is hard to justify.
What About a Rental With No Mortgage?
A paid-off rental can take a standalone first lien, and the caps are a little higher. These are loan-to-value figures, not combined, because no other lien exists.
On lines up to $500,000, the cap is 75% LTV at a 740 score or better. It is 70% LTV from 700 to 739. First-lien lines above $500,000, running to $1,000,000, are capped at 65% LTV at 720 or better. The first-lien floor is 700. Remember that a first lien exists only on a rental with no mortgage. A borrower with a mortgage stays in second-lien territory. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
An owner with a nearly empty first mortgage may sometimes find that a cash-out refinance replacing the first lien fits better than a line. That is a separate program with its own rules. Lendmire’s complete DSCR loans guide covers how the options fit together.
What the File Looks Like
The file is built around the rent, the lease, the credit report, and the valuation. None of these is skipped. Here are the points that most often shape a line request, all subject to underwriting.
Valuation. 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 need a full interior appraisal. Appraisal waivers are not accepted.
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).
Credit. The minimum is 720 on a second lien and 700 on a first lien. The mortgage history needs no 30-day late in the last 12 months. Bankruptcy, foreclosure, short sale, or deed-in-lieu needs 48 months of seasoning. No reserves and no cash to close are required.
Property. Eligible types include single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums. Rural-designated property, row homes, condotels, leaseholds, land trusts, mixed-use property, and properties with a solar lien are outside this lane.
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 limited to 5 loans or $2,500,000 per borrower with the program.
Draw Rules You Should Know Before You Size the Line
Plan the draw before the line, because the structure is less flexible than a typical revolving account.
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 must be at least $5,000 each. The draw period is 5 years, interest-only on the drawn balance. A 25-year fully amortizing repayment period follows, with a 30-year maturity. The rate is variable, and the lender’s HELOC disclosures carry the pricing terms.
The CFPB’s overview of home equity lines makes the general point that after the draw period ends, you can no longer borrow and repayment begins. The 80% closing draw has one consequence worth stating plainly. This is not a line to open “just in case” and leave idle. The investor who wants a standby reserve will find the structure a poor fit. The investor who has a defined use for the capital will find it a better one.
Keep the Line, Close It, or Refinance?
The answer turns on what you plan to do with the property.
| Goal | Path | Flip point |
|---|---|---|
| Sell within a year | Pay off at closing | New line is ruled out once listed |
| Hold and add capital | New line behind the first | Rent and CLTV room must both clear |
| First mortgage is the problem | Cash-out refinance | Replaces the first lien; separate program |
Say you own a rental with a modest first mortgage and a strong lease. A second-lien line may suit you, since it leaves the first mortgage untouched. Now say your first mortgage is the thing you want to change, or your equity need exceeds the line limit. Then the cash-out route is the cleaner answer. Lendmire’s piece HELOC for Sellers Who Still Owe on an Open Line covers the seller-side tradeoffs further.
A HELOC is a genuine toss-up for a hold-or-sell owner. A line adds optionality, but a possible sale makes it a short-term liability against the proceeds. Writing out both exits before drawing is worth the hour it takes.
Key Terms Defined
DSCR: debt service coverage ratio, meaning the rental’s monthly rent divided by the qualifying payment.
CLTV: combined loan-to-value, meaning the first mortgage balance plus the new line, divided by property value.
Draw period: the 5 years during which you can borrow on the line, paying interest only on the drawn balance.
Lien position: where a loan sits in line for repayment, with a second lien paid after the first.
Lien release: the recorded document that clears a paid-off line from title, even if the balance was zero.
Frequently Asked Questions
Does an open HELOC balance reduce how much I can borrow?
Yes. Every recorded lien comes out of the combined cap before any new line is sized. A drawn balance on an old line reduces your room the same way a first mortgage does. A zero balance does not remove the lien, so confirm with title that the old line is released.
Can I take a DSCR HELOC while my property is listed for sale?
No. A rental listed for sale in the prior 2 months is not eligible for this program. An owner who may sell should settle the question of a new line before listing. An existing line is a separate matter, and it is paid from proceeds at closing.
How long must I own the rental before opening 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). Both tests are measured from recorded dates, so check your closing documents.
Can the line be written in my LLC?
Yes, on investment property, subject to program terms. The LLC holds title, and the members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line need not be the borrowers on the first mortgage.
What happens to the line if I sell?
The balance is paid from sale proceeds through the title company, and the lender records a lien release. The line cannot be moved to another property. Net proceeds fall by the payoff amount, so a recent draw directly reduces what you walk away with.
