The Quick Read: Only when the lender on your next purchase accepts borrowed, documented funds and the rental behind the line can carry the extra debt without help from your paycheck. The line is a home equity line of credit on a rental you already own, qualified on that rent. The draw is cash you document and bring to the purchase. Whether it works comes down to four checks:
- The line sits on a rental you have owned for at least 6 months, not on your own home.
- The purchase lender decides if borrowed money counts, so ask before you draw.
- Rent is tested against a stress payment on the whole line, then your cash flow has to carry two debts.
- The draw usually helps the down payment bucket only. Closing costs and reserves are separate tests.
What Is the Structure, Exactly?
Two loans do two jobs. A DSCR HELOC on an existing rental supplies cash. A separate DSCR purchase loan buys the next property. The two files never close together.
The line is a standalone second lien behind the first mortgage you keep. If the rental is paid off, it can be a standalone first lien. Either way, the rent qualifies it and your personal income is never calculated. The LLC can stay on title, subject to underwriting and program terms.
This differs from a line on your own home. A primary-residence HELOC is an owner-occupied product, and this line is never written on an owner-occupied home.
Lendmire is a broker. It places these lines through a wholesale lender in its network, and the lender underwrites each file. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee: Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia and Washington.
Key Terms Defined
DSCR (debt service coverage ratio): monthly rent divided by the monthly debt payment. It shows whether the property pays for itself.
HELOC: a revolving credit line secured by property. You draw cash from it as you need it.
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value.
Seasoning: the waiting period a lender wants after you buy or refinance a property before it will lend against it again.
Draw period: the stretch when you can borrow from the line. On this program it runs 5 years, interest-only on the drawn balance.
Reserves: cash left in the bank after closing. Lenders count it as a safety cushion.
Will the Purchase Lender Accept Borrowed Down Payment Money?
Often yes, but it is not automatic. No regulator sets this rule for DSCR loans. Each lender writes its own, so the answer lives in the guidelines of the program buying the next property.
Across a wholesale network, files tend to land in one of three buckets:
| Treatment | What it means | What to ask |
|---|---|---|
| Fully accepted | Documented line draw counts as down payment | Any limit on source or amount? |
| Capped share | Part must be your own cash | What share can be borrowed? |
| Own funds only | Borrowed money is rejected | Is a smaller purchase an option? |
One BiggerPockets thread says only some lenders allow a HELOC for a down payment. WhiteCoat Investor confirms that HELOC funds can serve as an investment-property down payment, and that the size of your line depends on the equity you hold.
Large retail lenders tend to be the strictest, and specialty investor lenders tend to be the most flexible. A few lenders in a network will ask for some unborrowed, seasoned cash even when they accept the draw. Treat that as a question to answer before you open the line, not after you sign a contract.
Can This Line Even Be Opened on Your Rental?
Check the line’s own rules first, because a rental can fail them. They are ceilings and floors, never offers, and all are subject to underwriting.
- 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).
- Credit: at least 720 on a second lien and 700 on a first lien, with no 30-day mortgage late in the last 12 months.
- Leverage on a second lien: up to 70% CLTV at a 720 score or better, on lines from $50,000 to $500,000.
- Leverage on a first lien (rental with no mortgage): up to 75% LTV at 740 or better and 70% from 700 to 739, on lines to $500,000. Lines above $500,000, up to $1,000,000, top out at 65% LTV at 720 or better.
- Coverage: a minimum DSCR of 1.10x, measured against a stress payment on the entire credit limit. The lender’s own coverage calculation governs.
- Property: single-family, townhome, PUD, condominiums that meet program rules, and two-to-four units with at most one vacant. Rural property, condotels, row homes and leaseholds are outside it. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
The draw rules matter for this use. At least 80% of the line (never less than $50,000) is drawn at closing, and later draws are at least $5,000. So you cannot open a big line and sip from it. Size the line to the cash you actually need, because interest runs on what you draw.
What Does Documented Actually Mean?
Documented means a clean paper trail from the line to the closing table. Purchase lenders want to see where the money came from and that it is yours. Keep these in order:
1. The signed line documents for the HELOC.
2. The statement showing the draw and the balance.
3. Your bank statement showing the deposit.
4. The same funds, still traceable, when they move to escrow.
5. A short written explanation if the underwriter asks for one.
Some programs add a short seasoning requirement on the deposit. Others do not. That is program-specific, which is why the pre-draw call matters.
Here is the sequence that avoids trouble:
1. Get the purchase lender’s written position on borrowed funds.
2. Open the line and confirm the draw schedule.
3. Draw and park the cash in the account that will close.
4. Keep every statement.
Never move the money around casually. A deposit that bounces through three accounts is harder to trace than one that sits still.
Gift money and a relative’s credit line are different categories. A BiggerPockets reply notes that you cannot use a parent’s HELOC. The line has to be yours, or your entity’s.
Does the HELOC Payment Hurt Your DSCR on the Purchase?
Generally not. The purchase loan compares the new property’s rent to that property’s own payment. DSCR files do not run a personal debt-to-income calculation, so the line’s payment does not enter that ratio.
A conventional loan works differently. On a debt-to-income-based loan, a new line payment counts as a personal debt and can break the ratio. That is a big reason investors who borrow their down payment gravitate to DSCR. For the wider picture, see Lendmire’s complete DSCR loans guide.
Here is the catch. The ratio ignores the line, but your bank account does not. Passing the ratio is not the same as having positive cash flow.
Down Payment, Closing Costs, Reserves: Three Different Tests
Lenders treat these as separate buckets. A program may take borrowed money for one and not the others.
| Bucket | Borrowed funds often… |
|---|---|
| Down payment | Accepted, sometimes capped |
| Closing costs | Varies by program |
| Reserves | Often excluded |
The line itself requires no reserves and no cash to close. The purchase loan may have its own reserve test. If reserves matter on your deal, draw less against the line and keep your own savings intact. Ask the purchase lender which bucket each dollar will fill.
Does It Make Sense? A Two-Part Test
Approval is one question. Prudence is the other. Run both.
Part one, the property test. Does the new rental clear its coverage ratio on its own? A scenario that comfortably clears 1.2x on the purchase loan has cushion. One that barely touches 1.0x does not. Some select lenders in a network review purchases below 1.00 with adjusted leverage and terms, but a borrowed down payment on top of that is a lot of risk to stack.
Part two, the cash-flow test. Add the new property’s full payment to the line’s interest, then compare the total to rent after repairs and vacancy. The rent has to carry both. BiggerPockets investors repeat the same test: the new property carries its own mortgage plus the line.
Consider a rental that clears about 1.25x on the purchase loan. That looks healthy. Now fold in the line’s interest-only payment during the draw period. Cushion may shrink toward break-even before you budget a single repair. Then add a vacancy month and the real picture appears.
Sometimes the stronger play is a smaller line and a cheaper first purchase. Sometimes it is waiting for more savings. Reasonable investors differ here.
Stress Scenarios Worth Running
The line’s rate is variable, so the payment can change even if you draw nothing more. The CFPB’s HELOC booklet explains the structure of a draw period followed by a repayment period. Plan for these four pressures:
| Stress | What breaks | What cushions it |
|---|---|---|
| Vacancy | Rent stops, both debts continue | Own cash on hand |
| Variable rate moves up | Line payment rises | Smaller draw |
| Repairs | Cash goes out unplanned | Savings, not credit |
| Value drops | Equity cushion thins | Lower leverage |
The last row deserves attention. If the whole down payment is borrowed, you are effectively financing close to the full price across two properties. A BiggerPockets moderator makes this point: with a fully borrowed down payment you have no real equity cushion if values fall.
Your collateral is also different from a typical purchase. A default on the line puts the rental behind it at risk, not just the new property. That is a real risk concentration, and it is more contained than a line on your own residence.
One more practical point. If you plan to refinance the new property to pay off the line, a prepayment penalty on the purchase loan can interfere. Read the note before you count on that exit.
Practitioner Notes: How These Files Actually Go
In files like this, the stumbling block is rarely the coverage ratio. It is sequencing. Investors open and draw the line first, then learn the purchase lender wants own-funds seasoning or caps the borrowed share. The investors who avoid this call the purchase lender before they sign anything. A second common surprise is the 6-month ownership wait on the rental behind the line, which can stall a plan built around a recent purchase.
HELOC Versus the Alternatives
| Option | Best when |
|---|---|
| DSCR HELOC on a rental | You want to keep your low first mortgage |
| DSCR cash-out refinance | You want one fixed-term loan instead |
| Savings | You want the least risk |
| Smaller purchase | Funding is the bottleneck |
A line keeps your existing first mortgage in place and lets you pay interest only on what you draw. A cash-out refinance replaces that mortgage entirely. The right choice depends on the first mortgage you already have, the equity available and how long you plan to hold.
A rental line suits a hold of several years better than a short flip. A BiggerPockets investor argues a HELOC fits poorly with a 30-year hold, and a refinance exit may not work if appreciation is modest.
Exit Plan for the Line
Have one before you draw. The three real options are:
1. Pay it down from rent and savings.
2. Refinance the new property later and sweep the proceeds into the line.
3. Sell something.
Option one is the safest. Option two depends on appreciation and on any prepayment terms. Option three is the fallback, not a plan.
Go or No-Go Checklist
- The rental behind the line has been owned at least 6 months.
- Credit meets the tier (720 for a second lien, 700 for a first).
- CLTV stays at or under 70% on a second lien, or LTV within the first-lien tiers.
- The purchase lender confirmed in writing that borrowed funds count.
- The new property clears coverage with room to spare.
- Rent covers the new mortgage and the line, with a vacancy month budgeted.
- You hold cash outside the line for repairs and reserves.
Miss two or more and the answer is usually not.
Frequently Asked Questions
Can a DSCR HELOC draw be my entire down payment?
Sometimes, but it depends on the purchase lender. Some programs accept a documented draw in full. Others cap the borrowed share or want some of your own seasoned cash. Even where it is allowed, an all-borrowed down payment leaves you with no equity cushion, so many investors blend borrowed and own funds.
Does the HELOC payment lower my DSCR on the purchase?
Generally not, because the purchase loan compares that property’s rent to that property’s payment. The line payment still comes out of your cash flow. Run a second calculation that includes it before you commit.
Why can’t I borrow against my own home on this program?
This line is written only on non-owner-occupied one-to-four-unit rentals. A line on an owner-occupied home is a different product with different rules. The rental line is qualified on the rent and can sit in your LLC, subject to program terms.
What if the purchase lender refuses borrowed funds?
You have three choices: a smaller purchase, your own cash or a different program. Programs differ widely on this point, and a broker can compare several. Ask before you draw so that a refusal costs you nothing.
Can I use the same line again for another purchase?
Later draws are allowed at a minimum of $5,000 each during the 5-year interest-only draw period, subject to the line’s terms and your balance. The draw still has to meet the next purchase lender’s rules. Program exposure is capped at 5 loans or $2,500,000 per borrower.
