The Quick Read: A DSCR HELOC lets you borrow against the equity in a rental you already own, qualified primarily on that rental’s income, and put the cash toward the down payment on your next purchase. The line and the purchase are two separate files, so the purchase lender decides whether borrowed money counts. Everything below is subject to lender guidelines and underwriting.
- The line is a standalone second lien behind the first mortgage you keep, or a standalone first lien on a rental with no mortgage.
- The rent qualifies the line. Your personal income is not calculated.
- A second lien tops out at 70% combined loan-to-value, and a first lien at 75%, through select programs.
- At least 80% of the line is drawn at closing, so size it to the down payment you actually need.
- The new rental still has to carry its own loan and the cost of the borrowed cash.
What Is a DSCR HELOC?
A DSCR HELOC is a revolving line of credit secured by a rental property you own and qualified on that rental’s rent. It is written as a second lien behind your existing mortgage, or as a first lien if the rental has no mortgage. It is never a line on your own home.
Two terms first. DSCR, short for debt service coverage ratio, compares a property’s rent to its debt payment. A HELOC, short for home equity line of credit, lets you borrow against equity, which is the property’s value minus what you owe.
The phrase “DSCR HELOC” gets used two ways. Some people mean a line on their primary home that funds a down payment on a DSCR-financed rental. That is a consumer product judged on your personal income, and it is a different animal. Here it means a line drawn against a rental you own, qualified on rent, with the cash funding a down payment on a separate property.
Picture an investor holding a duplex with a low-balance first mortgage and strong rent. She wants to buy a fourplex without refinancing the duplex or opening her tax returns. She takes a line on the duplex, draws the cash, and uses it toward the fourplex. That is the whole idea. The details decide whether it works.
How Does a DSCR HELOC Work for an Investor’s Down Payment?
The sequence has six steps, and the order matters. The line closes first. The purchase loan comes after, under its own approval.
1. Confirm the source rental is eligible. You need real equity in a one-to-four-unit rental, a lease in place, and a clean property type. A two-to-four-unit building can have at most one vacant unit. A first-time investor with no rental has nothing to borrow against, so this route is closed to them.
2. Clear the seasoning clocks. 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). Seasoning is simply the waiting period a lender wants between events. A cash-out refinance on the source rental restarts it.
3. Pass the coverage test on the whole line. The program divides gross monthly rent by a qualifying payment. That payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points, a built-in stress test. The minimum coverage is 1.10x. Taxes and insurance are not part of the qualifying payment. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of 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. The lender’s own math governs.
1. Get the valuation. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
2. Draw the cash. At least 80% of the line is drawn at closing, and later draws are at least $5,000 each. The money lands in your account as a documented draw from the line.
3. Close the purchase under a separate DSCR loan. That loan is reviewed on the new property’s rent against its own payment, plus credit and leverage limits. The purchase lender traces the down payment back to the line draw and decides whether it accepts borrowed funds.
Steps one through five happen on the old property. Step six happens on the new one. Keep them mentally separate and most of the confusion disappears.
What Does the Program Actually Allow?
A second lien reaches up to 70% combined loan-to-value (CLTV) at a 720 credit score or better, on lines from $50,000 to $500,000, subject to underwriting. CLTV adds your first mortgage balance and the new line, then divides by the property’s value. There is no second-lien tier below 720. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
A first lien exists only on a rental with no mortgage. It reaches 75% loan-to-value (LTV) at 740 or better and 70% at 700 to 739, on lines to $500,000. Lines above $500,000, up to $1,000,000, cap at 65% LTV at 720 or better. Credit floors are 720 on a second lien and 700 on a first lien. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Here is what that looks like in percentages. Say your first mortgage balance equals about 50% of the rental’s value. A second lien at the 70% CLTV ceiling leaves room for a line worth about 20% of value. The lender’s valuation sets the real number.
The rest of the structure:
- Draw period: 5 years, interest-only on the drawn balance.
- Repayment period: 25 years, fully amortizing, for a 30-year maturity.
- Rate: variable. The rate and pricing terms come with the lender’s disclosures.
- Credit history: no 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
- Reserves and cash to close: none required on the line.
- Exposure: at most 5 loans or $2,500,000 per borrower with the program.
- Ownership: your LLC can hold title on an investment property, subject to program terms. Members sign as guarantors.
- Borrowers: U.S. citizens, permanent residents, and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Rural property, row homes, condotels, mixed-use, leaseholds, land trusts and properties listed for sale in the prior 2 months are outside this lane. A declining-market flag lowers the ceiling 5 points.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is a broker. It arranges the line through a wholesale lender in its network. It does not lend.
This line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. For how DSCR files work more broadly, see Lendmire’s complete DSCR loans guide.
Second Lien, First Lien, or Cash-Out Refinance?
The choice usually comes down to one question: do you want to keep the first mortgage you have? A line adds a lien. A cash-out refinance replaces your first mortgage with a bigger one.
| Factor | DSCR HELOC | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place (second lien) | Paid off and replaced |
| How you get cash | Revolving line, drawn at closing and later | One lump sum at closing |
| Draw structure | 5-year interest-only draw period | No draw period |
| Source rental afterward | New lien added; first mortgage untouched | Restarts seasoning on that rental |
The refinance has its own rules, leverage caps and costs, and they differ from the line’s.
A line tends to win when your existing first mortgage is worth keeping and you want the cash in stages. A refinance tends to win when you want one clean loan and the existing mortgage has no special value.
Where the General Rule Breaks
The headline rule is simple: the line funds the down payment, and the purchase loan buys the property. These cases bend it.
The purchase lender may reject borrowed funds. Across Lendmire’s wholesale network, programs differ. Some accept a documented line draw as the down payment. Some cap the borrowed share. Some want unborrowed cash. Large retail lenders often resist borrowed down payments altogether. Ask the purchase lender before you open the line, not after.
A fully borrowed down payment is the hardest version. Borrowing the entire down payment means the new property starts with essentially 100% leverage across two loans, as investors on BiggerPockets point out. Some programs decline it even when the rent coverage is strong. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Down payment, closing costs and reserves are separate pots. A program may accept borrowed funds for one and not the others. Borrowed money is commonly excluded from reserves. Line draws are also meant to be a sourced deposit, not cash that appears the week before closing.
The 80% closing draw can overshoot. Most of the line comes out on day one, and on the smallest lines the whole line does. You pay interest on what you draw. A line much bigger than the down payment you need means carrying idle borrowed cash. Size the line to the need.
The prepayment penalty can collide with an early payoff. Many investors plan to pay the line down fast with a cash-out refinance on the new property. That can run into a step-down prepayment penalty, which is a fee for paying a loan off early, on the purchase loan. One BiggerPockets thread describes exactly that collision. Read the purchase loan’s penalty terms before building the exit plan.
The draw period ends. The interest-only stretch is five years, then a 25-year amortizing repayment begins. The CFPB’s explanation of a HELOC notes that monthly payments are often much higher once repayment starts. Plan for the step up.
The line puts a lien on the source rental. If the new deal underperforms, the lender’s claim runs to the property securing the line. That is the real downside.
Does the Deal Still Cash-Flow?
This is where careful investors separate from hopeful ones. Clearing the coverage ratio and paying for itself are different tests.
The HELOC payment generally stays out of the new property’s DSCR. But it still has to be paid from somewhere. On a conventional purchase, the line’s payment would typically count in your debt-to-income ratio. Under DSCR underwriting, your personal debt-to-income ratio is not the constraint. Cash flow is.
Run the numbers on a modeled scenario. Say the new rental clears its own payment at roughly 1.25x. That looks healthy. Now add the interest on the drawn line, paid from the same rent. The cushion shrinks and can slide toward break-even. The ratio the lender sees stays at 1.25x. Your bank account sees something thinner.
The stronger play is to treat the line as a second monthly obligation on the new property. Strong rent against both payments is a deal. Rent that covers only the purchase loan is a bet. Borrowed down payments also mean no built-in equity cushion in the new property, so a soft market has less room to hide.
Investors who plan to pay the line down quickly, with a flip or a refinance, tend to carry the cost more comfortably than buy-and-hold investors planning to live with the line for years. It is a genuine toss-up for long holds. The rent math decides, not the strategy label.
On the interest itself, 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.
A first-time investor with no rental is better off with savings, seller credits, a partner, or a smaller first purchase.
Key Terms Defined
Second lien: a loan secured by a property that already has a first mortgage, paid after the first mortgage if the property is ever sold to satisfy debts.
Combined loan-to-value (CLTV): the first mortgage balance plus the new line, divided by the property’s value.
Draw period: the stretch when you can borrow from the line. Here it is 5 years, interest-only on what you have drawn.
Repayment period: the stretch after the draw period when you can no longer borrow and the balance amortizes. Here it runs 25 years.
Qualifying payment: the stress payment the lender divides rent by. It is a fully amortizing payment on the whole credit limit at the start rate plus 2 percentage points.
Seasoning: the waiting period a lender requires after you buy or refinance before a new loan is allowed.
Frequently Asked Questions
Can a DSCR HELOC cover the entire down payment?
Sometimes, but it is the hardest version to place. The line can supply the cash, yet the purchase lender decides whether borrowed funds count. Some programs cap the borrowed share or want some unborrowed cash. A fully borrowed down payment also means very high leverage across two loans, which can run past the combined loan-to-value limits that second liens and purchase programs typically apply. Ask the purchase lender first. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Does the HELOC payment lower the new property’s DSCR?
Generally no. The purchase loan is reviewed on the new property’s rent against its own payment, and the line’s payment stays out of that ratio. The payment still has to come out of cash flow. A deal can clear the coverage test and still run thin once both payments exist.
How long do I have to own a rental before I can borrow against it?
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 cash-out refinance on the source rental restarts the first clock.
Can I put the line on my own home?
No. This line is secured by a non-owner-occupied rental. A line on an owner-occupied home is a different consumer product, underwritten on personal income and debts. This program is never offered on an owner-occupied home or a second home.
Can my LLC hold the property and the line?
Yes, on an investment property, subject to program terms. The LLC can stay on title, and its members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
