The Quick Read: The best fit is a standalone line of credit on a rental you already own, qualified on that rental’s income. You draw the cash, season it in your account, and then use it as part of the down payment on the next rental. The line and the purchase loan are two separate files, and the purchase lender decides whether it accepts borrowed funds. Which program fits depends on your lien position, credit tier, equity, and how many loans you already carry.
- The line is a standalone second lien behind your first mortgage, or a standalone first lien on a rental with no mortgage. It is never closed together with a purchase.
- Rent qualifies it at a minimum 1.10x coverage, with no personal income calculation and no traditional personal-income documentation, subject to lender guidelines.
- Second-lien leverage tops out at 70% combined loan-to-value (CLTV). First-lien leverage reaches 75% loan-to-value (LTV) at the top credit tier.
- At least 80% of the line is drawn at closing, so size it to the cash you need.
- Lines run through select programs in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee, subject to underwriting.
What Does a DSCR HELOC Actually Do for a Down Payment?
It turns equity in a rental you keep into cash for the next purchase, without refinancing the first mortgage and without opening your personal income file. That is the whole job. The line does not buy the property. A separate purchase loan does that.
You will see “DSCR HELOC” used loosely online. Some pages mean a line on your own home. Others mean a purchase loan with a line bolted on. Neither is this program. Through the wholesale network Lendmire works with, the line sits on a non-owner-occupied one-to-four-unit rental. It is never offered on your own home or a second home. It is never a third lien.
DSCR stands for debt service coverage ratio. It is the monthly rent divided by the monthly payment the lender uses to test the loan. A DSCR loan is built for investment properties. Because it is a business-purpose investor loan, it is reviewed differently from a standard owner-occupied mortgage. Lendmire’s complete DSCR loans guide covers the purchase side in depth.
Think of the portfolio as a chain. Rental one carries equity. The line converts part of that equity to cash. The cash becomes part of the down payment on rental two. Rental two gets its own DSCR purchase loan, qualified on its own rent.
Your LLC can stay on title, subject to program terms. The members sign as guarantors. 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.
How Underwriting Treats the Line, Step by Step
The lender tests the rental, the equity, and your credit, in that order of importance. Here is the sequence a file follows.
1. Pick the rental that carries the line. It needs a lease in place. A two-to-four-unit property can have at most one vacant unit. 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).
2. Set the rent. The lender uses the lesser of the appraiser’s Form 1007 market rent or the lease. A lease above market can count if you have three months of receipts.
3. Run the coverage test. Gross monthly rent is divided by a stress payment. That payment is fully amortizing, calculated on the entire credit limit at the start rate plus 2 percentage points. The minimum coverage is 1.10x. The undrawn part of the line counts, so an oversized line hurts your ratio.
4. Check combined leverage. On a second lien, the lender adds your first mortgage balance and the new line, then divides by value. The ceiling is 70% CLTV, and the program requires a 720 credit score or better. The lender’s own coverage calculation governs how the first mortgage payment is treated on a second lien. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
5. Order the valuation. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines need a full interior appraisal. Appraisal waivers are not accepted.
6. Review credit and borrower status. No 30-day mortgage late in the last 12 months. At least 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. Citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
7. Close and draw. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
No reserves and no cash to close are required on the line, subject to underwriting. Every figure here is a ceiling or minimum on select programs, never an offer. Whether the line is approved is the lender’s call on each file.
The Program Tiers at a Glance
Lien position drives most of the math. The table lays out what the network’s program allows, subject to underwriting.
| Factor | Second lien | First lien (no mortgage) |
|---|---|---|
| Leverage measure | CLTV, up to 70% | LTV, up to 75% |
| Credit needed | 720 or better | 700 or better |
| Top tier | 740+: 70% CLTV | 740+: 75% LTV |
| Mid tiers | 720-739: 70% CLTV | 700-739: 70% LTV |
| Line size | $50,000 to $500,000 | $50,000 to $1,000,000 |
| Lines over $500,000 | Not available | 65% LTV at 720+ |
| Seasoning | 6 months since last note date and 6 months on title | Same |
Two details trip people up. First, there is no second-lien tier below 720. Second, a first-lien line above $500,000 drops to 65% LTV, so bigger lines do not mean bigger leverage. A declining-market flag on the property lowers the ceiling by 5 points. Lines in Philadelphia carry a ceiling 10 points lower. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
What “Best” Means for a Rental Portfolio
The best program for your situation is the one where the structure, the leverage and the exposure limits fit the plan. Rate-shopping is not the test. Lendmire works with a network of wholesale lenders and matches the file to a program. The lenders that write this product vary in their overlays, so the match matters more than any single headline number.
Here is the checklist a broker runs, in order of how often it decides the file:
- Lien position. Do you keep the first mortgage, or is the rental free and clear? That decides the leverage table above.
- Combined leverage. How much of the rental’s value is already spoken for? A first mortgage using most of the 70% CLTV leaves too little room to bother.
- Credit tier. A 740 score unlocks the top first-lien leverage. A 700 score is the program’s lowest entry point, and only on a first lien.
- Property type. Single-family, PUD, townhome, two-to-four units, and condominiums are eligible. Rural property, row homes, condotels, leaseholds, and mixed-use are not.
- Exposure. The program caps a borrower at 5 loans or $2,500,000. A growing portfolio can hit that ceiling before it runs out of equity.
- Draw mechanics. You must draw most of the line at closing, so a $50,000 minimum is the real floor on your cash need.
- Exit plan. The line is interest-only for 5 years on the drawn balance, then moves to a 25-year fully amortizing repayment period, with a 30-year maturity. The rate is variable. You need a plan for when it turns into a full payment.
Walking a Portfolio: Rental One Funds Rental Two
Two scenarios show how the structure plays out. Both are illustrative, use percentages instead of dollars, and are not offers.
Scenario one: a rental with a first mortgage. Say you own a duplex that has held title for well over 6 months. The first mortgage uses about half of its value. The program’s 70% CLTV cap leaves about 20 points of value for a line, and your score is 735. That is inside the 720 tier. The lender runs the 1.10x test on a stress payment calculated on the whole limit, using the rent from the lease and the Form 1007 schedule. If the rent clears that test, the line can proceed. The valuation path depends on line size.
Scenario two: a paid-off rental. You own a fourplex free and clear. At a 740 score, the first-lien ceiling is 75% LTV on lines up to $500,000. The 1.10x test still applies to the entire limit at the stress payment. Here the whole line is first lien, so there is no first mortgage payment to weigh. A line above $500,000 would drop to 65% LTV. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Now the second leg. Rental two is bought with a DSCR purchase loan. That loan is qualified on rental two’s own rent against its own payment. A larger down payment means a smaller first loan and a smaller payment, which lifts the coverage number. The line’s payment does not enter that ratio in the usual DSCR math. You still owe it.
Rental one and rental two must both carry. If rental two’s rent only barely clears its own payment, the line’s payment lands on your pocket, or on the rent from rental one. Ask what happens at 1.00x on rental two before you draw.
The next step in the chain works the same way. Rental two needs 6 months before it can carry its own line, and the 5-loan or $2,500,000 exposure cap counts every loan you hold with the program. Plan the chain around those limits, not around equity alone.
Where the General Rule Breaks
Four edge cases change the answer.
You do not own a rental with equity. The program never lends against your own home or a second home. If your only equity is in your residence, a primary-residence home equity line is a different, owner-occupied product with its own rules. It is not what this article covers.
The purchase lender’s rules on borrowed funds. Rules for a borrowed down payment belong to the purchase loan, not to the line. Some DSCR purchase programs accept borrowed funds with a paper trail. Others restrict them or ask for more. There is no single rule across all lenders, so the answer comes from the specific purchase program you pick. Ask first.
Effectively full financing. Between the purchase loan and the line, you may have borrowed close to the whole price. That is workable on a short hold, where the line is repaid by a refinance or a sale. It strains a long hold, where both payments run for years.
Variable payments and the end of the draw period. The CFPB’s HELOC explainer notes that HELOCs usually carry variable rates, so payments can change from month to month. Its booklet on HELOCs also describes a repayment period that follows the draw period. On this program the draw period is 5 years of interest-only payments on the drawn balance. After that, a 25-year fully amortizing repayment begins. Payments can step up sharply at that point, so model the repayment phase now.
Tax treatment varies; consult a qualified professional before relying on any deduction.
Which Route Fits Which Situation?
The line is one of several ways to fund a down payment. The table shows where each fits. Other programs’ rules are theirs, not this program’s.
| Situation | Likely route | Why |
|---|---|---|
| Free-and-clear rental, want cash | First-lien line | Keeps no first mortgage to disturb |
| First mortgage worth keeping | Second-lien line | Leaves the first mortgage alone |
| Need a larger lump sum, fine to reset | DSCR cash-out refinance | Replaces the first mortgage |
| Rental bought within 6 months | Wait | Seasoning not yet met |
| Cash on hand | Cash down | No second payment |
A DSCR cash-out refinance replaces the first mortgage. A line leaves the first mortgage alone, which matters if its terms are better than today’s market.
Ask Before You Draw
Run this sequence with both lenders. A broker can put these questions to the purchase lender while the line file is open.
1. Does the purchase program accept borrowed funds, and what paper trail does it want? 2. Must the funds season in your account before the contract, and for how long? 3. Does the purchase lender separate down payment, closing costs and reserves? 4. Does the purchase program require reserves? The line itself requires none. 5. What is the rental’s coverage if the rent drops or vacancy hits? 6. How many loans do you already hold with the program, and how close are you to 5 loans or $2,500,000? 7. What is the exit for the line: refinance, sale, or paydown from cash flow?
Order matters. Know the purchase lender’s answer on borrowed funds before the line closes, since the 80% minimum draw puts most of the line on your balance right away.
Key Terms Defined
DSCR (debt service coverage ratio): the rental’s monthly rent divided by the payment the lender uses to test the loan.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
Second lien: a loan that sits behind your first mortgage in repayment priority on the same property.
Draw period: the stretch when you can borrow from the line. On this program it is 5 years, interest-only on the drawn balance.
Seasoning: the waiting period a lender requires before a property or funds become eligible.
Form 1007: the appraiser’s single-family rent schedule, which sets market rent.
Frequently Asked Questions
Can a DSCR HELOC cover the entire down payment on a rental?
It can supply cash toward the down payment, but whether it can be the whole amount depends on the purchase program. Some programs limit borrowed funds or ask for a portion from your own money. Ask the purchase lender before you draw.
Does the line’s payment affect the DSCR on the new rental?
Not in the usual way. The purchase loan is qualified on the new rental’s rent against its own payment. The line’s payment is still real, so the cash flow from your portfolio has to cover it.
Can I borrow against a rental held in an LLC?
Yes, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment and the security instrument. The property must be investment property.
How many lines can I stack across a portfolio?
The program caps each borrower at 5 loans or $2,500,000, whichever comes first. Every loan with the program counts toward that limit. Each rental also needs its own seasoning, lease and coverage.
Is a line better than a cash-out refinance for a down payment?
It depends on whether you want to keep your first mortgage. A line leaves the first mortgage untouched and adds a second payment. A cash-out refinance replaces the first mortgage with one new loan. The right pick depends on your first mortgage’s terms, your equity and your plan.
