The Quick Read: A DSCR HELOC supplies the cash while a separate DSCR purchase loan buys the short-term rental, so the line must sit on a rental you already own, qualify primarily on that property’s rent covering the payment, and produce funds the purchase lender will accept as a down payment, all subject to lender guidelines. The two loans never merge, and each gets its own approval.
- The line is a standalone second lien behind your first mortgage, or a standalone first lien on a paid-off rental. It is never closed with a purchase.
- Through select programs, the line needs a 1.10x coverage ratio on a stress payment, a 720 score on a second lien, and up to 70% combined leverage.
- The purchase lender decides whether borrowed money counts as down payment, and it may treat down payment, closing costs and reserves differently.
- The line payment sits outside the new property’s coverage ratio, but it still comes out of your bank account every month.
How the Two-Loan Setup Works
The structure is simple to say and easy to get wrong. One loan is a line of credit on a rental you keep. The other is the mortgage on the short-term rental you are buying. Each lender looks at a different property.
| Factor | DSCR HELOC | DSCR purchase loan |
|---|---|---|
| Secured by | A rental you already own | The short-term rental you buy |
| Lien position | Second or first lien, standalone | First lien on the new property |
| What it funds | Cash you draw | The purchase balance |
| What is tested | Rent against the line’s stress payment | Income against the new loan’s payment |
Lendmire is a broker, so it arranges both pieces through select lenders in its wholesale network. It does not lend on either one. Your first-time reading of the file will feel like two separate mortgages because it is exactly that.
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. If you want the full background on how these loans work, Lendmire’s complete DSCR loans guide covers it.
Key Terms Defined
DSCR (debt service coverage ratio): monthly rent divided by the monthly payment the lender counts, such as principal, interest, taxes, insurance and any HOA dues on a purchase loan.
HELOC: a revolving line of credit secured by property equity, which you draw from as needed up to a limit.
Second lien: a loan that sits behind your first mortgage. If the property is ever sold or foreclosed, the first mortgage is paid first.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
Draw period: the years when you can borrow from the line and pay only interest on what you have drawn.
Source of funds: the paper trail showing where your down payment cash came from.
Seasoning: a waiting period between events, such as buying a property and borrowing against it.
What the Line Itself Requires
The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. There is no traditional personal-income documentation: no W-2s, pay stubs or personal debt-to-income calculation. The lender does document the lease, your credit report and the property value.
Here is the core of what select programs in the network ask for.
| Item | Second lien | First lien |
|---|---|---|
| Collateral | Rental with a mortgage you keep | Rental with no mortgage |
| Minimum score | 720 | 700 |
| Maximum leverage | 70% CLTV | 75% LTV at 740+; 70% LTV at 700 to 739 |
| Line size | $50,000 to $500,000 | To $500,000, then to $1,000,000 |
On a first lien, lines above $500,000 carry a 65% LTV ceiling at 720 or better. 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. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
The coverage test. Gross monthly rent has to reach 1.10x the qualifying payment. That payment is a fully amortizing principal-and-interest payment on the entire credit limit at an assumed higher rate than the start rate. Taxes and insurance are not part of it. Because the stress payment covers the whole limit, a bigger line makes the test harder to pass even if you draw less than the limit later.
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. A two-to-four-unit property can have at most one vacant unit. On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation, because the lender’s own calculation governs.
Draws and terms. The draw period is 5 years, interest-only on the drawn balance. A 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable. At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. Later draws are at least $5,000 each.
That 80% rule matters for planning. You cannot open a large line and leave most of it unused. Size the line to the cash you need, because interest-only payments start on most of it right away.
Credit and exposure. Mortgage history needs no 30-day late in the last 12 months. The program wants 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required. Each borrower is limited to 5 loans or $2,500,000 with the program.
Valuation. Lines up to $400,000 use an automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal. Larger lines 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).
Who and what is eligible. U.S. citizens, permanent residents and non-permanent residents with a Social Security number can apply. Foreign nationals and ITIN borrowers cannot. Single-family homes, PUDs, townhomes, two-to-four units and condominiums are eligible property types. Rural property, condotels, row homes, leaseholds, land trusts, age-restricted communities, mixed-use buildings, properties listed for sale in the prior 2 months and properties with a solar lien are outside this lane.
The line can be vested in your LLC, subject to program terms. The members sign as guarantors.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. All figures here are ceilings and floors through select programs, subject to underwriting. They are not offers.
Will the Purchase Lender Accept Borrowed Money?
Sometimes. This is a purchase-program rule, not a HELOC rule. Some DSCR purchase programs accept borrowed funds for the down payment, and others want unborrowed cash. The same program may treat down payment, closing costs and reserves as three separate pots and accept borrowed money in only one of them.
Anecdotes show the range. In one BiggerPockets thread on using a HELOC to buy an investment property, a lender wanted the funds to sit in the borrower’s account for two months. That is one lender’s practice, not a rule. The same thread points to reserves as the harder place to use HELOC money.
Across Lendmire’s wholesale network, the practical pattern is that purchase lenders look at the cash after you draw it. It lands in your own bank account. The lender then applies its own sourcing and seasoning rules to those funds.
Ask the purchase lender these questions before you draw anything:
1. Are borrowed funds allowed for the down payment at all?
2. Are they allowed for closing costs and reserves?
3. Must the money sit in my account for a set period before the contract?
4. What paperwork shows where the draw came from?
5. How is the line’s payment treated in your calculation, if at all?
Get the answers in writing. Then pick the line size.
Does the Line Payment Hurt Your Coverage Ratio?
On the purchase loan, the coverage ratio compares the new property’s income with the new property’s payment. The line’s payment is not part of that ratio. That is why people say a DSCR HELOC does not hurt the DSCR.
That statement is true and also misleading. Your bank account still pays both obligations. The line is interest-only on the drawn balance during the draw period, and the new loan’s payment starts at the same time. One investor in a BiggerPockets thread on a HELOC-funded short-term rental points out that using a HELOC means paying interest on 100% of the borrowed dollars and starting with no equity in the deal.
Think of it as two tests. The first is the lender’s ratio. The second is your own cash-flow test, and the lender does not run it for you.
How the Purchase Loan Sees Short-Term Rental Income
The purchase side has its own income evidence, and it varies by program. Programs commonly look at some mix of a hosting history, a property management statement, or a market-data projection of nightly income. The appraiser’s rent survey, Form 1007, often reads lower than a busy short-term rental’s potential. Which evidence a program accepts, and what leverage and score it asks for, are set by the lender on the purchase file.
One more distinction trips people up. The property being bought is not the collateral for the line. The collateral is a rental you already own. The program’s rent test is built around a lease and the appraiser’s market rent, so a rental on a long-term lease is the cleanest collateral. If your existing rental is itself a short-term rental, confirm early how the lender will count its income.
A Worked Scenario in Ratios
Consider an investor who owns a leased duplex outright and wants to buy a short-term rental. These are modeled assumptions, not market data.
The duplex has no mortgage, so the line would be a first lien. A score of 740 or better allows up to 75% LTV. Suppose the lender’s test shows rent covering the full-limit stress payment at 1.25x. That clears the 1.10x minimum with some room. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
The investor sizes the line to the down payment and nothing more. At least 80% is drawn at closing, so the investor opens a line that is close to the amount needed. After closing, the draw sits in the investor’s bank account and seasons if the purchase lender requires it.
Then the purchase loan is underwritten on its own. The short-term rental’s income is documented under that program, and the new loan’s coverage ratio ignores the line. In a peak month, both payments are easy to cover. In a slow month, the vacation property earns less while the line’s payment stays the same, since it is tied to the drawn balance. That slow-month test is the one that matters.
Now change one thing. If the investor had a first mortgage on the duplex, the line would be a second lien. The investor would need a 720 score, and the first mortgage balance plus the line could reach 70% CLTV. The coverage test would also come out differently, and the lender’s own calculation governs how.
The Sequence, Step by Step
1. Check the purchase lender’s rules first. Ask the five questions above.
2. Pick the collateral. It must be a one-to-four-unit rental you own, leased, outside the excluded list, past both six-month clocks.
3. Size the line. Match it to the cash you need, not the largest line you can get.
4. Close the line on its own. It is never closed with the purchase.
5. Draw and park the cash in your account. The purchase lender will see it as bank funds.
6. Document the short-term rental’s income under the purchase program.
7. Close the purchase loan.
8. Plan the payoff. Pay the line from cash flow, savings or a later refinance.
Document what you draw and when. Source-of-funds paperwork matters whenever borrowed money is involved.
Where the Rule Breaks
Borrowed money in the wrong pot. HELOC cash may work as a down payment and still be rejected for reserves or closing costs.
No collateral rental. A first-time investor with no rental has nothing to borrow against. This line is never offered on your own home or a second home.
A line on the new property. The short-term rental you are buying cannot secure the line at purchase. The line is never closed with a purchase, and the 6-month clocks block it right after.
Entity quirks. An LLC can hold title, but a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Full leverage. A BiggerPockets thread on a HELOC down payment shows the risk. When both the down payment and the loan are borrowed, there is no cushion if income slips.
A prepayment penalty on the next loan. If you later refinance to pay off the line, check whether the new loan carries a prepayment penalty. That is a purchase-and-refinance question for each file.
A primary-home line. A home equity line on your own residence is a different, owner-occupied product. Its terms can restrict renting out the home, so read that agreement before you borrow against it, as the CFPB’s overview of HELOCs explains for lines in general. The same page notes that falling behind on a line can put the secured home at risk.
DSCR HELOC, Cash-Out, Primary-Home Line, or Cash?
| Option | Collateral | Reviewed on | Best when |
|---|---|---|---|
| DSCR HELOC | Existing rental | Rent covering a stress payment | You keep a low-leverage first mortgage |
| DSCR cash-out refinance | Existing rental | The refinance program’s coverage test | You want one new loan replacing the old |
| Primary-home HELOC | Your owner-occupied home | Personal income, per that product | You accept personal-residence risk |
| Cash | None | Nothing to qualify | You have savings to spare |
A DSCR cash-out refinance replaces your first mortgage, and a DSCR HELOC leaves it alone. If your existing mortgage is worth keeping, the line is the cleaner tool. If not, the refinance may fit better.
When This Is the Wrong Move
The line is a bridge, not permanent capital. It is a variable-rate product, so its payment can move. It works best when you have a plan to pay it down within a year or two, rather than a hope that the new property will carry it.
Skip it if the new property barely clears its own payment. Skip it if your savings cannot absorb two payments during a slow stretch. Skip it if the purchase lender will not take borrowed funds, because you will have paid for a line you cannot use as planned.
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.
Frequently Asked Questions
Can a DSCR HELOC cover my entire down payment?
It can cover as much as the line size and leverage limits allow, but whether it counts depends on the purchase lender. Many programs accept borrowed funds in some form, and some do not. Ask whether the purchase program treats down payment, closing costs and reserves differently. If the whole down payment is borrowed, you carry two payments from day one.
How long do I have to own the rental before opening the 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 must be satisfied for the collateral property.
Can my LLC hold the property?
Yes, subject to program terms. The line allows vesting in the owner’s LLC on an investment property. The 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 match the borrowers on the first mortgage.
Can I use this if I have never owned a rental?
No. The line is secured by a rental you already own and keep, and it is never offered on an owner-occupied home or a second home. A first-time investor without a rental would look at other funding for the down payment, such as savings or a different loan product.
Does the line payment lower my coverage ratio on the new loan?
No, the new loan’s ratio compares the new property’s income with its own payment. The line’s payment still reduces your real cash flow. Model both payments against a slow month, not a peak one.
