The Quick Read: The best program for your situation is a standalone line of credit on a rental you already own, qualified on that rental’s income, with the draw sent to your account to fund the down payment on the next purchase. It works only when two separate approvals both hold: the line must close first, and the purchase lender must accept borrowed money as a down payment source. The new rental must cover its own payment, and your real monthly cash flow must also carry the line.
- A DSCR HELOC is a second lien (or a first lien on a rental with no mortgage) on a rental you keep. It is never closed together with a purchase.
- The line is qualified on the rental’s rent, with a 1.10x minimum coverage test. It does not use your personal income.
- The purchase lender decides whether borrowed funds count, and the answer can differ for the down payment, closing costs and reserves.
- A line payment does not enter the purchase loan’s coverage ratio, but it still comes out of your pocket every month.
- No true zero-down DSCR purchase exists. The line only changes where the down payment comes from.
Key Terms Defined
DSCR (debt service coverage ratio): gross monthly rent divided by the monthly payment the property has to carry.
DSCR HELOC: a revolving line of credit secured by a non-owner-occupied rental, qualified on that rental’s rent instead of the owner’s personal income.
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value.
Seasoning: the time you have owned a property, or the time since a purchase or refinance, before a program treats it as eligible.
Borrowed funds: down payment money that came from a loan instead of your savings. Lenders usually require it to be documented and may limit how much of it counts.
Reserves: liquid cash a lender wants left in your accounts after closing. It is tested separately from the down payment.
How Does a DSCR HELOC Fund a Down Payment?
It is a two-loan structure with two separate files. The line is secured by a rental you already own. The purchase loan is secured by the new property. Cash moves from the first to the second through your own bank account.
Lendmire is a mortgage broker, so the sequence below is how files run across the wholesale network it works with.
1. Qualify the source rental. It must be a one-to-four-unit, non-owner-occupied rental with a lease in place. It must also have enough equity to leave room under the combined leverage ceiling.
2. Close the line. The line is written as a standalone second lien behind the first mortgage you keep. It can also be a standalone first lien if the rental has no mortgage. It is never combined with the purchase, and it is never placed on the property you are about to buy.
3. Draw and park the funds. The draw lands in your account, or in your LLC’s account if the line is vested there. That account holds the money while the purchase moves forward.
4. Document the source. The purchase lender wants statements showing the draw and where it went. Lenders often want to see the money in your account before it counts.
5. Close the purchase. The purchase file is underwritten on its own. The new rental’s rent is tested against the new loan’s payment.
The line payment does not enter the purchase file’s coverage ratio. A larger down payment lowers the purchase loan payment, so it can lift that ratio. The line payment is still a real obligation. CFPB’s HELOC explainer describes a HELOC as an open-end line you borrow against repeatedly. It also notes that a lender can restrict further credit if the home’s value drops significantly. That is why Lendmire’s guidance is to get the line closed before shopping for the purchase.
What Does Best Mean When You Are Short on Cash?
The best program depends on the property, the equity, your credit profile and what the purchase lender will accept. No single lender wins for every file. A broker that shops several wholesale lenders matches the scenario to the program, and the criteria below are what separate programs for a down payment shortfall.
| Criterion | Why it matters for a shortfall | What to ask |
|---|---|---|
| Rent-qualified line | Keeps your personal income out of the file | Does the rent test use the lease or market rent? |
| Lien position | Decides how much equity you can reach | Second lien or first lien on this rental? |
| Draw rules | Sets how much cash you take on day one | What share is drawn at closing? |
| Entity title | Decides whether the LLC can stay on title | Are guarantor and title-holder signatures required? |
| Purchase lender fit | The purchase lender controls borrowed-fund acceptance | Is a documented draw accepted toward the down payment? |
| Property eligibility | An ineligible source rental ends the plan | Does the rental type fall inside the program? |
The last two rows matter most. A line that closes cleanly is no help if the purchase lender rejects the funds.
What Does the Program Itself Look Like?
The mechanics below are ceilings and floors across select programs, subject to underwriting. They are never offers.
Qualification. The rent qualifies the line. Under this program, there is no traditional personal-income documentation, such as W-2s or pay stubs, and no debt-to-income ratio, subject to lender guidelines. The minimum coverage is 1.10x. That is gross monthly rent divided by a stress payment, which is a fully amortizing payment on the entire credit limit. Rent is the lesser of the appraiser’s Form 1007 market rent or the lease. A lease in place is required. A two-to-four-unit property can have at most one vacant unit. On a second lien, the lender’s own coverage calculation governs how the first mortgage payment is treated.
Leverage. The program states leverage differently by lien.
- On a second lien behind your first mortgage, CLTV reaches up to 70% at a 720 credit score or better, on lines up to $500,000.
- On a first lien with no mortgage, LTV reaches up to 75% at 740 or better on lines up to $500,000. It is 70% from 700 to 739.
- First-lien lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. Every figure here varies by lender and program: guidelines, property type, leverage, and credit profile all apply.
Draw terms. Lines start at $50,000. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000. 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 rate and pricing terms come with the lender’s disclosures.
Credit. The minimum score is 720 on a second lien and 700 on a first lien. The program requires no 30-day mortgage late in the last 12 months. It also requires 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required on the line. A borrower can have at most 5 loans or $2,500,000 with the program.
Valuation. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines require a full interior appraisal. Appraisal waivers are not accepted.
Where it is offered. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Those states are Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia and Washington. Foreign nationals and ITIN borrowers are not eligible. For the full picture of how DSCR financing fits together, see Lendmire’s complete DSCR loans guide.
Will the Purchase Lender Accept Borrowed Funds?
It depends on the purchase program, and this is the point where most plans of this kind succeed or fail. Across the wholesale network, many DSCR purchase programs accept a documented draw from a line on another property toward the down payment. Some cap the borrowed share, and a few want a minimum from your own savings. Programs that sit with large retail lenders are often the strictest. That is why the purchase lender should be asked in writing before the line is opened.
Treat three pots separately, because a program can accept borrowed funds for one and reject them for another.
- Down payment: the pot most often open to a documented draw.
- Closing costs: commonly treated the same way as the down payment.
- Reserves: often required to be unborrowed. The line itself requires no reserves, but the purchase loan may.
Investors also hear conflicting stories, which is understandable. One BiggerPockets discussion shows investors reporting that borrowed down payment funds went through on their purchases. Investors in other threads say a bank turned them away. Both reports can be true, because treatment varies by program.
The documentation file is short but strict.
- Statements showing the draw leaving the line and landing in your account.
- Statements showing the money sitting there before closing.
- The line’s closing documents, so the lender can see the new obligation.
- Entity documents, if the draw lands in an LLC account.
A draw that arrives right at closing with no paper trail is the usual reason a file gets stuck.
How Do You Size the Draw to the Shortfall?
Size the line to the gap, but expect the minimums to force a larger draw than a small gap needs. At least 80% of the line is drawn at closing, and never less than $50,000. A small shortfall can therefore leave you holding idle borrowed cash, and the variable-rate balance costs money while it sits in your account.
| Gap size | Practical path |
|---|---|
| Small gap | Use savings or seller credits. The draw minimum may be larger than the gap. |
| Mid-size gap | A line near the program minimum can fit, with the excess applied to reserves from your own funds. |
| Large gap | A larger line, a first-lien structure, or a blend of line, savings and partner capital. |
A blended down payment is often safer than a fully borrowed one. A fully borrowed down payment means roughly 100% financing across two loans, so the rent has to carry both payments. Some purchase programs reject that outright.
What Does the Math Look Like in Ratios?
Run the numbers on a modeled deal, using ratios and percentages. These are illustrative inputs, not market facts, and the lender’s own calculation governs.
Say you own a rental with a first mortgage at about 40% of its value. A second lien up to 70% CLTV leaves roughly 30% of value in reach, subject to the $500,000 line cap and the credit and valuation requirements above. The source rental’s rent has to clear the 1.10x test on a stress payment sized to the whole credit limit. That is a tougher test than the drawn balance alone would suggest.
Now say the new purchase clears roughly 1.2x on its own loan. The purchase file looks clean. Your real cash flow then has to carry three layers.
1. The new rental’s rent against its own loan payment.
2. The line payment, which is interest-only on the drawn balance during the draw period.
3. The first mortgage on the source rental, which keeps running.
A simple carry test is the new rental’s rent minus its loan payment, minus the line payment. If that number goes negative, the deal depends on your personal income to stay current, and the lender’s coverage ratio will not warn you. CFPB’s HELOC booklet explains that with a variable rate, monthly payments can change even when you draw nothing more. A draw period that ends and moves into principal-and-interest payments is the other point that catches investors off guard.
This is a genuine judgment call. Some investors in a BiggerPockets thread argue that a line suits a short hold, such as a BRRRR plan with a planned refinance, better than a long hold on a 30-year loan. The strongest argument for the line is the cash-flow math, and the strongest argument against it is leaving a variable-rate balance outstanding for years.
What Is the Right Order and Timing?
Order matters. The line comes first, the draw follows, and the purchase contract goes in only after the funds are documented. If the closing date arrives before the funds are cleanly documented, the file can stall or the down payment can be rejected.
Seasoning applies to the source rental. 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). A rental you just bought cannot fund your next purchase through this program.
Tax treatment varies; consult a qualified professional before relying on any deduction.
How Does It Compare With Other Ways to Fill the Gap?
| Option | Best fit when |
|---|---|
| DSCR HELOC on a rental | You own a seasoned rental with equity and want to keep its first mortgage |
| DSCR cash-out refinance | The first mortgage on the source rental is worth replacing |
| Partner capital | You want to share equity instead of adding personal debt |
| Seller credits | The gap is mostly closing costs |
| Savings | The gap is small, or the purchase lender wants unborrowed funds |
A cash-out refinance on a seasoned rental swaps your first mortgage for a new, larger one. A line leaves the first mortgage untouched.
Where Does the General Rule Break?
Several property and borrower details can end the plan before it starts.
- Primary residence lines. A line on your own home is a different, owner-occupied product.
- Ineligible source rentals. Rural property, row homes, condotels, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts, mixed-use property, a property listed for sale in the prior 2 months, and a property with a solar lien fall outside the program.
- Declining markets. A declining-market flag lowers the leverage ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower.
- LLC title. Vesting in your LLC is allowed on an investment property. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. Entity document gaps are a common source of delay.
- Insurance. Hazard insurance has to cover both liens, with flood coverage where required.
What If You Do Not Own a Rental Yet?
A DSCR HELOC needs an existing, seasoned rental, so a first-time investor has no line to draw on. The practical routes are savings, seller credits where the contract allows them, a partner, or a lower-priced first purchase with a smaller down payment. After a first rental is seasoned, equity on it becomes the source for the next one.
Frequently Asked Questions
Can a DSCR HELOC cover the whole down payment on a rental?
It can on some programs, but it depends on the purchase lender. Some accept a fully borrowed down payment, and others require a minimum from your own funds or a cap on the borrowed share. A fully borrowed down payment also means two loans carried against one rent stream, so the cash-flow test gets harder.
Does the line payment hurt my DSCR on the new rental?
Usually it does not. The purchase file’s ratio compares the new rental’s rent with the new property’s own payment, and the line payment generally sits outside it. Your actual monthly cash flow still carries the line, so run the carry test before drawing.
Can the line sit on the property I am buying?
No. The line is a standalone lien on a rental you already own and is never closed together with a purchase. The property you are buying can only be financed by the purchase loan.
Do borrowed funds count toward reserves?
Often they do not. Many purchase programs want reserves unborrowed, even when they accept a documented draw for the down payment.
Is there a true zero-down DSCR purchase?
No. A line only changes where the down payment comes from, and the purchase loan still has its own down payment, credit and property requirements.
