The Quick Read: Money drawn from a home equity line is borrowed, so a DSCR lender decides under its own guidelines whether it counts fully as down payment, counts up to a cap, or must be paired with cash you already hold and have seasoned. Two lenders are involved, and the purchase lender’s answer is the one that matters. Ask before you open or draw the line.
- The line lender approves the line. The purchase lender decides how the draw is treated.
- On an investment property, a line through the network tops out at 70% combined loan-to-value. On a primary residence the ceiling reaches 90% only at a 720-or-better credit profile.
- Down payment, closing costs and reserves are tested separately. Borrowed money is least reliable as reserves.
- The line payment sits outside the DSCR ratio but inside your real cash flow.
- All figures here are subject to lender guidelines and full file review.
DSCR, short for debt service coverage ratio, compares a rental’s income to its monthly housing obligation. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. That is why investors ask about borrowed down payments: the loan looks at the property, but the cash to close still comes from somewhere.
Two Lenders, Two Files
Two separate approvals sit behind this strategy, and they are underwritten differently. One lender decides whether you get the line. A different lender decides whether the money you drew counts toward the purchase.
The phrase portfolio lender gets used two ways. A bank that keeps loans on its own books is a portfolio lender in the older sense. Here it means a lender that writes its own guidelines instead of following one agency rulebook. Lendmire arranges DSCR loans through a wholesale network of these lenders, and no single rule governs what they do with borrowed funds. Each program’s overlay decides.
A third use matters later. A portfolio DSCR loan puts several rentals under one note. The section on that structure comes after the basics.
For background on how the loans themselves work, see Lendmire’s complete DSCR loans guide.
How Underwriting Treats the Draw, Step by Step
Here is the sequence a file usually follows, from the line to the purchase lender’s review.
1. Line approval. The line lender reviews credit, debt-to-income, equity and collateral. A NerdWallet explainer notes that a HELOC on a rental is possible but not offered by all lenders, and that qualification is strict because lenders see higher default risk on rentals. On the lines Lendmire brokers, debt-to-income tops out at 50%. It is measured on the interest-only payment at the maximum draw.
2. Open and document the line first. The line must be secured by property you already own. It cannot sit on the rental you are about to buy. Have it open and documented before the purchase contract goes in. Opening it afterward is not ideal.
3. Draw and move the money. Draw the funds, deposit them in your own account and keep the statements. Draw early enough that the deposit is not a fresh, unexplained item on recent statements. That is a good habit, not a DSCR rule.
4. Purchase-lender review. The DSCR lender divides the subject property’s rent by its PITIA, which is principal, interest, taxes, insurance and any HOA dues. The line payment generally sits outside that ratio. Across the network, program treatment of borrowed money falls into three camps:
- accept a documented line draw as down payment,
- cap the borrowed share, or
- require a slice of unborrowed, seasoned cash.
5. Paper trail. Expect to provide the line agreement or statements showing the draw, the transfer into your account, and account statements tracing the money to closing.
What decides the outcome:
- whether the program accepts borrowed funds at all,
- whether it wants a minimum of unborrowed money,
- which pot the money is for,
- whether the rent clears the coverage floor,
- the leverage tier, and
- your credit.
Three Buckets, Three Different Answers
The same draw can pass one test and fail another. A purchase file has three pots of money, and a program may treat each differently.
| Pot | Can borrowed funds count? | What the lender checks |
|---|---|---|
| Down payment | Program-dependent: accepted, capped or paired | Draw trail, total leverage |
| Closing costs | Varies; may differ from down payment | Same trail, plus source |
| Reserves | Not reliably; a line is debt, not an asset | Verified, unborrowed assets |
Most single-rental purchases through the network land at 75% to 80% LTV on a purchase, so 20% to 25% down. Select programs reach 85% LTV at roughly a 700 score. That down payment is the pot people try to fund with a line. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Reserves work differently. They are the months of PITIA you hold after closing. They commonly run around six months, though they vary by lender, leverage, loan size and transaction type. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Larger loans typically step up to about nine months. Borrowed money does not prove you can absorb a bad stretch, so lenders resist counting it here.
Where the Line Payment Sits
The DSCR ratio uses the subject property’s rent and its PITIA. Your line payment is not in that math. It is still a real monthly cost, and it lands on your budget.
Picture an investor buying a duplex at 75% LTV on a purchase, so 25% down. Assume rent clears the full obligation at roughly 1.2x. The investor draws on a line against their home to fund the 25%. The DSCR still reads 1.2x. But now two payments come out of one rental’s income: the new mortgage and the line. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities and capital expenses all sit outside the calculation. Coverage near 1.00 leaves little room to carry a second payment.
For context, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger coverage opens better pricing and higher leverage, but it never erases the equity requirement.
Now the harder case. Say the investor borrows the entire 25%. That investor has financed essentially the whole purchase. A program that wants unborrowed cash may decline the file on that point alone, even with strong rent coverage. The strongest files clear both tests: enough equity and enough rental coverage.
Line on Your Home or Line on a Rental?
Occupancy changes the ceiling. Through the network, the two kinds of line compare like this.
| Factor | Primary residence line | Investment property line |
|---|---|---|
| Max CLTV | 90%, only at 720+ | 70% |
| Minimum credit | Tiered; 720+ for top ceiling | 700, a hard floor |
| Line size | $25,000 to $750,000 | Up to $500,000 |
| Draw structure | 3-year or 5-year draw options | 5-year draw, 25-year repayment |
| Valuation | Automated at or under $500,000 | Automated; commonly no appraisal |
CLTV is the total of all loans against the property as a share of its value. On a primary residence, a line above $500,000 needs a 700 or better credit profile (720 on the longer-runway structure) and a full appraisal. The 90% ceiling appears only with a 720-or-better profile. On an investment property, 720 and 700 both reach the same 70%, so a higher score buys eligibility, not leverage.
The NerdWallet explainer cites a typical 10-year draw period followed by up to 20 years of repayment. A White Coat Investor guide reports investment-property line requirements of roughly a 720 score, debt-to-income no higher than 50%, at least 20% equity and an LTV not above 80%. Those are market-wide figures. On the network Lendmire brokers, an investment-property line caps at 70% CLTV with a 700 minimum, and at least 75% of the line is drawn at closing. Pricing floats during the draw and repayment periods and never converts to fixed.
That 75% draw rule changes the sizing question. You do not get to leave most of the line idle. Size it to the money you need, not the most you can get.

What Changes When the Purchase Is a Portfolio Loan
A portfolio DSCR loan, also called a blanket or cross-collateralized loan, is one note secured by several rentals. Two structures exist.
The 30-year portfolio DSCR loan covers 2 to 20 properties under one note. Loan sizes run $300,000 to $5,000,000, with larger balances on review. Leverage goes up to 80% of value on purchase and rate-and-term. Coverage is measured on the pool, so pooled rent is tested against pooled debt service, with a 1.00 floor. An interest-only period is available. Eligible property types are single-family, two-to-four-unit, condo and townhome.
The rental portfolio term loan covers five or more rental properties or units. Loan sizes run $500,000 to $50,000,000, with leverage up to 75% of value. Terms are fixed at 3, 5, 7 or 10 years with a balloon at maturity. It can be recourse, meaning a personal guarantee, or non-recourse, where the lender looks to the real estate with recourse limited to carve-outs such as fraud and bankruptcy. Small multifamily is eligible only on this term loan. Properties in several markets can sit under one note.
The credit floor on these portfolio programs is 640, and 680 or 720 on some structures. A rental below 1.00 coverage can sit inside a pool, but underwriting tests the pooled coverage, the leverage and the terms. Every property still needs a lease or an appraiser-supported market rent.
Why does this matter for a line? The down payment is larger in absolute terms. A single investment line caps at $500,000, and a borrower is limited to three lines. One line may not fund a portfolio-sized down payment. Cash-out on a portfolio loan never exceeds 75% of pooled value, and a cash-out inside the first six months of ownership is capped by a cost-basis seasoning rule. Portfolio leverage ceilings bind regardless of how much cash you bring.
Where the General Rule Breaks
Several situations change the answer.
LLC-owned rentals. Many DSCR loans can be made to an LLC, subject to lender program eligibility. A home equity line cannot. Title must sit with the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change or a DSCR cash-out refinance instead.
Borrowing close to 100%. When the line funds the full down payment, you are financing essentially the whole deal. Some programs decline that point alone.
DTI-based loans. If you leave DSCR for a debt-to-income loan, the line payment counts. Fannie Mae’s borrowed funds guidance accepts asset-secured borrowed funds for down payment, closing costs and reserves, and requires the secured-loan payment to count as debt. Its monthly debt obligations section puts a line with a required payment into recurring debt. That is the conventional default. DSCR programs are not agency products, so they may or may not mirror it, and the reserves treatment in particular does not carry over.
Debt limits. A borrower owning more than 15 financed properties is not eligible for the line. Combined exposure also has caps.
The draw-period cliff. On an investment line, the 5-year interest-only draw ends and a 25-year fully amortizing repayment begins. Plan your exit before you draw, whether that is rent, savings or a refinance.
Prepayment terms. If you plan to refinance out of the line soon after buying, check the prepayment terms on the DSCR note first. A prepayment penalty can complicate an early exit.
Property type. Manufactured homes are not reviewable on these programs. Co-ops, condotels, log homes and commercial or mixed-use property are not eligible for the line.
Risk to your home. A line on your primary residence puts a lien on it. A bad rental outcome can reach your house.
If the Purchase Lender Says No
A refusal does not end the deal. Several paths exist.
| Fallback | Best when | Watch for |
|---|---|---|
| Cash-out on an owned rental first | The rental has seasoned equity | About six months of seasoning |
| Larger share of your own cash | You hold liquid savings | Reserves still apply |
| A different program | Lender overlays differ | Terms and leverage may adjust |
A cash-out refinance on a standard rental tops out around 75% LTV across most of the network. The ceiling is 70% on a short-term-rental collateral. Proceeds that sit documented in your account read as your own cash. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Pre-Draw Checklist
Put these questions to the purchase lender before you open or draw.
1. Does the program accept borrowed funds for the down payment?
2. Is there a cap on the borrowed share?
3. Is a slice of unborrowed, seasoned cash required?
4. Do closing costs follow the same treatment?
5. Can any borrowed money count as reserves?
6. What documents show the draw and transfer?
7. What does the prepayment term look like if I refinance out of the line?
8. Does my vesting, entity or trust work for the line?
Key Terms Defined
CLTV: the total of all loans on a property as a share of its value.
Debt-to-income (DTI): your monthly debts as a share of your income, used on the line and on conventional loans.
Draw period: the window when you can borrow from the line before repayment starts.
Source of funds: the documented origin of the money you bring to closing.
Seasoning: the time money has sat in your account, or the time you have owned a property.
Reserves: liquid assets you hold after closing, usually measured in months of PITIA.
Frequently Asked Questions
Can I use a HELOC for the down payment on a DSCR rental?
Often, but it depends on the program. Some accept a documented draw, some cap the borrowed share, and some require unborrowed seasoned cash. Ask the purchase lender before you open or draw the line.
Does the line payment lower my DSCR?
Generally no. The ratio uses only the subject property’s rent and PITIA. The payment still hits your real cash flow, and it counts against you on a debt-to-income loan.
Can HELOC money count as reserves?
Not reliably. A line is debt, not an asset, and lenders usually want verified, unborrowed assets for reserves. Some programs may treat it differently, so confirm before relying on it.
Can I take the line on the rental I’m buying?
No. The line must be secured by property you already own, held in your name or a revocable trust. A rental deeded to an LLC points toward a DSCR cash-out refinance instead.
How much can I borrow against an investment property?
Through the network, up to 70% CLTV with a 700 minimum credit score, and lines top out at $500,000. A primary residence reaches 90% CLTV only at a 720-or-better credit profile.
