The Quick Read: The best program depends on your situation, but the structure is the same everywhere: a line of credit secured by a rental you already own supplies the cash, and a separate loan buys the new property. The line is reviewed on its rent, and the purchase lender decides whether the drawn funds count as acceptable down payment money. Lendmire, a mortgage broker, matches the file to a wholesale program.
- A DSCR HELOC is a standalone second lien behind your first mortgage, or a standalone first lien on a paid-off rental, qualified on rent rather than personal income.
- Through select programs, a second lien reaches 70% combined loan-to-value at a 720 score or better, on lines up to $500,000, subject to underwriting.
- You need an existing, seasoned rental. First-time investors with no rental need a different route.
- The HELOC payment sits outside the new property’s coverage ratio, but it still comes out of your real cash flow.
- Ask the purchase lender how it treats borrowed funds before you draw a dollar.
What Is a DSCR HELOC, and Why Use One for a Down Payment?
A DSCR HELOC is a revolving line of credit on a non-owner-occupied one-to-four-unit rental, qualified on the property’s rent instead of the owner’s personal income. It is written as a standalone second lien behind the first mortgage you keep, or as a standalone first lien on a rental with no mortgage. It is never closed together with a purchase, and it is never a line on your own home.
The appeal is simple. You reach equity in a rental you want to keep, without refinancing a first mortgage you may like, and without opening your personal income file. The rent, the lease, the credit report and the valuation are all documented. What drops out are tax returns, W-2s, pay stubs and a debt-to-income calculation. Qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines.
A HELOC is an open-end line you can borrow against repeatedly, and its rate is usually variable. That describes the product category. This particular program has its own structure, covered below. For the broader picture of how these loans work, see Lendmire’s complete DSCR loans guide.
How Does the Underwriting Work, Step by Step?
Two loans, two approvals. The line is approved on the rental securing it. The purchase loan is approved on the new property. Neither file approves the other.
1. Pick the collateral. It must be a rental you own, with a lease in place. A two-to-four-unit property may have at most one vacant unit.
2. Size the line. On a second lien, combined loan-to-value counts your first mortgage balance plus the new line, divided by value. The cap is 70% CLTV at 720 or better, on lines up to $500,000.
3. Run the coverage test. Minimum DSCR is 1.10x. Gross monthly rent is divided by a qualifying payment calculated on the entire credit limit, using a stress assumption. Rent is the lesser of the appraiser’s market rent or the lease. The lender’s own calculation governs. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
4. Value the property. Lines 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.
5. Draw the cash. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each.
6. Document the funds. Keep the line terms, the statements showing the draw, and the deposit trail into the account that will fund the purchase.
7. Apply for the DSCR purchase loan. This is a separate file with its own leverage, credit and reserve rules. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Zero-down does not exist on a DSCR purchase. Borrowed funds do not waive down payment, reserve or credit requirements.
First Lien or Second Lien: Which Structure Fits?
If your rental still carries a mortgage, you are in second-lien territory. If it is paid off, a first lien opens up more room. The tiers differ, so label every figure by lien position.
| Factor | Second lien (CLTV) | First lien (LTV) |
|---|---|---|
| Top leverage | 70% CLTV | 75% LTV |
| Score for top tier | 720 or better | 740 or better |
| Credit floor | 720 | 700 |
| Line size | $50,000 to $500,000 | Up to $1,000,000 |
| Larger lines | Not offered | 65% LTV above $500,000 |
On a first lien, 720 to 739 and 700 to 719 both sit at 70% LTV on lines to $500,000. All figures are ceilings through select programs, subject to underwriting. A declining-market flag lowers the ceiling by 5 points, and the actual number depends on the property. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
The practical tradeoff: a second lien keeps your existing first mortgage intact, which matters if that first loan is a good one. A first lien on a free-and-clear rental can pull more equity, but it only works if there is no mortgage to protect.
Will the Purchase Lender Accept Borrowed Funds?
Sometimes. Across a wholesale network, treatment of borrowed down payment funds varies by program. Some accept a documented draw. Others cap the borrowed share or want unborrowed cash in the file. Nobody should tell you it is universally accepted or universally banned.
Three buckets matter, and lenders often treat them differently:
| Bucket | Often treated as | What to ask |
|---|---|---|
| Down payment | Borrowed funds sometimes accepted | Is there a cap on the borrowed share? |
| Closing costs | Borrowed funds sometimes accepted | Same rule as down payment? |
| Reserves | Borrowed funds often excluded | Must reserves be unborrowed? |
The pattern we see is that reserves are where borrowed money gets refused most often. Plan your own cash for that bucket.
Seasoning is the other gate. Some purchase lenders want drawn funds to sit in your account for a period before closing. Ask what that period is before you draw, not after.
What Makes a DSCR HELOC the Best Fit for a Down Payment?
No single program wins. Judge fit by criteria:
- Leverage ceiling. How much cash can the rental’s equity actually release after the first mortgage?
- Draw structure. At least 80% drawn at closing means you pay interest on most of the line immediately. Size the line to your need, not to the maximum.
- Draw and repayment terms. This program has a 5-year interest-only draw on the drawn balance, then a 25-year fully amortizing repayment, with a 30-year maturity. The rate is variable. The CFPB notes payments often rise sharply at repayment on lines generally.
- 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).
- Exposure cap. At most 5 loans or $2,500,000 per borrower with the program. Investors building a portfolio hit this ceiling.
- Property type. Rural property, condotels, row homes, mixed-use and leaseholds are outside it.
- Entity title. Vesting in your LLC is allowed on investment property, subject to program terms, with members signing as guarantors.
- Fit with the purchase lender. The best line on paper fails if the purchase program rejects the funds.
A broker that shops several wholesale lenders can test those criteria against your file. That is the real value of the question of which program is best. The answer depends on property type, credit profile, leverage need and how the purchase lender treats borrowed funds.
Does the HELOC Payment Count Against the New Property’s DSCR?
Usually not. The new loan’s ratio compares that property’s rent to its own payment: principal, interest, taxes, insurance and any HOA dues. A line secured by a different property generally sits outside that calculation.
But a passing ratio does not mean the deal cash flows. The line’s interest comes out of your pocket every month. A deal can clear 1.2x on the purchase loan and still run thin once you add the draw cost on top.
Run a stress test before you commit:
- Rent against the new property’s full payment.
- Plus the interest on the amount drawn.
- Plus a scenario where the variable rate moves higher.
- Then ask what happens when the interest-only period ends.
If the deal only works in the best case, the line is carrying a deal that should not be done. As the NerdWallet explainer notes, an investment-property HELOC puts the secured property at foreclosure risk if you cannot pay. Experian makes the same point about the lender’s ability to foreclose on that property. Your existing rental is the collateral for your new down payment.
Where the General Rule Breaks
First-time investors. A rent-qualified line needs an existing, seasoned rental. If you own none, you need another route, such as a line on your primary home. That is a different, owner-occupied product, and the lien risk falls on the place you live.
Prepayment clashes. Buying with a DSCR loan and then refinancing early to repay the line can run into a prepayment penalty on the purchase loan. Ask about the penalty structure before you plan an early payoff.
Same-week plans. The line is never closed with the purchase. It must exist, season and be drawn first. Sequencing matters more than most investors expect.
Equity trade-off. If the entire down payment is borrowed, you hold little real equity in the new property. A price dip leaves you exposed on two properties at once.
Short-term rental income. Short-term rental rules can vary by city, county, HOA and property type, so investors should confirm local rules before relying on projected rental income.
Eligible borrowers. US citizens, permanent residents and non-permanent residents with a Social Security number qualify. Foreign nationals and ITIN borrowers are not eligible on this program.
HELOC, Cash-Out Refinance or Cash: How Do They Compare?
| Option | Best fit | Watch for |
|---|---|---|
| DSCR HELOC (second lien) | Keep a good first mortgage | Variable rate, 6-month seasoning |
| DSCR HELOC (first lien) | Paid-off rental | Lower ceiling above $500,000 |
| DSCR cash-out refinance | Replace the first loan and pull equity | New first-mortgage terms |
| Cash savings | Simplest underwriting | Ties up liquidity |
The HELOC leaves your first mortgage in place and adds a second lien. A cash-out refinance replaces the first lien entirely.
Key Terms Defined
CLTV (combined loan-to-value): Your first mortgage balance plus the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line and pay interest only on the drawn balance. Here it is 5 years.
Repayment period: The stretch after the draw period when the balance amortizes. Here it is 25 years.
Seasoning: The time a property has been owned or a loan has been in place before it can qualify.
Standalone second lien: A loan secured by a property behind a first mortgage, closed on its own, not alongside a purchase.
DSCR: Gross monthly rent divided by the qualifying payment. This program requires a minimum of 1.10x.
What Should You Do Before You Draw?
Sequence is the whole game. A workable order:
1. Ask the purchase lender whether borrowed funds count, in which bucket, and with what seasoning.
2. Confirm the rental securing the line meets the seasoning rule and has a lease in place.
3. Size the line to the down payment and closing costs, not the maximum.
4. Open the line, and draw into your own account.
5. Keep statements showing the draw and the deposit, and be ready to explain large deposits.
6. Apply for the purchase loan as a separate file.
Frequently Asked Questions
Can the HELOC be the entire down payment?
Sometimes, but it depends on the purchase program. Some lenders cap the borrowed share or require part of the cash to be unborrowed. Reserves are the bucket most often restricted. Ask before drawing.
Does the HELOC payment lower my DSCR on the new loan?
Usually not. The purchase loan’s ratio compares that property’s rent to its own payment. The line’s payment still reduces your real monthly cash flow, so model both together.
Can an LLC hold the line?
Yes, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. Vesting is allowed on investment property only.
Where is this program offered?
In 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Property eligibility and all figures are subject to underwriting.
Is zero-down possible on the purchase?
No. Borrowed funds supply the down payment but do not waive it, nor credit or reserve rules. The DSCR purchase loan keeps its own leverage tier.
