The Quick Read: A HELOC can cover a down payment shortfall on a rental when two separate approvals line up. The line lender approves you against equity in a property you already own. The DSCR purchase lender then decides whether borrowed funds count and whether the rent covers the payment.
- The line is secured by a property you already own, so it must be in place before the rental closes.
- The DSCR lender decides whether borrowed funds count as a down payment, and programs differ on that rule.
- DSCR measures rent against the new property’s payment only. Your line payment sits outside the ratio but still hits your cash flow.
- Down payment and reserves are separate requirements. Borrowed cash often cannot fill both.
- On Lendmire’s network, a line on an investment property is limited to 70% CLTV and $500,000 total.
How a HELOC Helps You Purchase Investment Property for a Down Payment Shortfall
A HELOC is a funding source, not a purchase loan. It does not buy the rental. It puts cash in your account, and that cash goes toward the down payment and closing costs on a separate DSCR loan.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
That makes two loans, two sets of collateral, and two approvals. The new rental secures the DSCR loan. Your home, or another property you own, secures the line. Losing the rental does not release the line.
You cannot open a line against a property you have not bought yet. That is why the order matters. Raise the plan with your DSCR broker before you open the line, and certainly before you go under contract.
A shortfall is a gap, not the whole down payment. Most purchase files land between 75% and 80% LTV on a purchase of an investment property, which means 20% to 25% down. Select programs reach 85% LTV on a purchase, with 15% down and roughly a 700 or better score. The gap is whatever your own seasoned cash cannot cover, plus closing costs. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Key Terms Defined
HELOC: A revolving credit line secured by a property you own, usually with a draw period followed by a repayment period.
CLTV: Combined loan-to-value, which adds every loan secured by the property and divides by its value.
DSCR: Debt service coverage ratio, which is monthly rent divided by principal, interest, taxes, insurance and any HOA dues on the property being financed.
PITIA: The monthly total of principal, interest, taxes, insurance and association dues.
Seasoned funds: Money that has sat in your account long enough for a lender to treat it as yours rather than as new borrowing.
Reserves: Liquid funds a lender wants left after closing, commonly measured in months of PITIA.
Will the DSCR Lender Accept Borrowed Down Payment Funds?
It depends on the program, and this is the question that decides most of these files. Some programs accept a documented line draw as the down payment. Some cap the borrowed share or want a slice of your own seasoned cash. Some require unborrowed funds only.
A plan that relies on 100% borrowed money can fail on that point alone. In effect you would be financing close to the whole purchase. Many programs are built to stop exactly that.
Across the wholesale network, the pattern is consistent. Lenders want to see where the money came from and where it landed. A clean file usually includes:
- the line’s closing documents,
- a draw confirmation,
- bank statements showing the draw landing in an account in your name,
- the statements that show the rest of your funds, with no unexplained deposits.
Ask three things before you open the line. Do documented line proceeds count as down payment? Is there a minimum of your own funds? Can any of it also count toward reserves? Get the answers from the program, not from a general rule.
The complete DSCR loans guide covers how these programs are built if you want the full structure first.
How Underwriting Treats the Line, Step by Step
1. Choose the collateral. A line on your primary home is the common route. It is easier to get, but it puts your residence behind the investment. A line on an existing rental is harder. Bankrate reports that these lines are less common and cost more than lines on a primary home.
2. Size the line. The basic formula takes the home’s appraised value, applies the lender’s percentage, and subtracts what you still owe. Your income, debts and credit history also count.
3. Get the line approved. This approval rests on you, your equity and your credit. The DSCR lender is not part of it, and neither approval guarantees the other.
4. Draw the cash and park it. Move the draw into an account in your name. Keep it traceable. Do not mix it with unrelated deposits.
5. Run the purchase through DSCR underwriting. The lender divides the new property’s rent by its PITIA. Leverage caps, credit floors, reserves and property eligibility all still apply.
6. Check reserves separately. Reserves vary by lender, leverage, loan size and transaction type. Around 6 months of PITIA is common. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up to about 9 months. Borrowed cash often cannot double as both the down payment and the reserves.
7. Test your own monthly cash flow. The question is whether your total cash flow survives the added payment.
The Two Tests Every File Must Pass
The strongest files clear both tests. One looks at the property. The other looks at you.
| Factor | DSCR purchase lender | Line lender |
|---|---|---|
| What it reviews | Rent against PITIA | Your equity, credit, debts |
| Collateral | The new rental | Your home or a rental you own |
| Key limit | LTV cap, credit floor, reserves | CLTV cap, DTI, credit floor |
| Borrowed funds | Program-dependent | Not applicable |
On the DSCR side, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and more leverage. Credit follows a similar ladder. A 620 floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), subject to lender guidelines.
On the line side, a higher down payment on the rental can lift the DSCR, but it never erases leverage caps, credit floors, reserve rules or property eligibility.
Here is the catch that surprises people. Clearing 1.00 does not mean the property cash flows. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities and capital expenses sit outside the calculation. Your line payment sits outside it too.
What the Network’s Home Equity Lines Look Like
Lendmire brokers home equity lines through select wholesale partners. It does not lend them. Lines are available in 16 full-service states, a narrower footprint than the DSCR side, which covers 40 states plus Washington, D.C., 41 markets in all. Every figure below is subject to lender guidelines and a full file review.
Investment property lines. The ceiling is 70% CLTV, with no tier above it. The maximum line is $500,000. The minimum credit profile is 700, and 700 and 720 both reach the same 70% CLTV. Extra credit buys eligibility rather than leverage. Lines of this size ordinarily run on an automated valuation, so a traditional appraisal is often not required.
Primary residence lines. The ceiling reaches 90% CLTV, and only at a 720 or better credit profile. That is a top tier, not the general case, and it never applies to an investment property.
Draw structure. Investment lines run a 5-year interest-only draw followed by a 25-year repayment. Primary and second-home lines can also use a 3-year draw with a 17-year repayment. Pricing floats during both the draw and the repayment period and never converts to a fixed structure.
The 75% rule matters for shortfalls. At least 75% of the line is drawn at closing. You cannot open a large line and draw a sliver. If your gap is small, a small line fits better. A larger line means you carry interest on money you did not need.
DTI. The maximum is 50%, and it is qualified on the interest-only payment calculated on the maximum draw. That means the underwriter assumes you borrow the full line, not just what you plan to use.
Title and property. Title must sit with you as an individual or in a revocable living trust. A property deeded to an LLC cannot hold the line. DSCR loans can close in an LLC, subject to lender program eligibility, but the line side cannot, so entity structure needs planning before either closes. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties are not eligible for the line. DSCR is also not offered on manufactured homes, log homes or barndominiums.
Sizing the Draw to the Gap
Start from the shortfall, not the line limit. Add the down payment gap, closing costs and any reserve gap. Then ask what your own cash covers.
Take a purchase at 75% LTV. The down payment is 25%. If your seasoned cash covers most of that, the line only needs to fill the remainder and closing costs. A program that wants a slice of your own funds is happy with that mix. A program that requires unborrowed funds only will not move on a draw at all. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
A draw that is too large costs you in two ways. You pay interest on idle cash from day one. The larger payment also shows up when the underwriter reviews your file on the maximum draw.
If the available line is smaller than the gap, you have three honest options. Raise more of your own cash. Move to a lower-leverage purchase. Or choose a smaller property. Do not fix the gap by borrowing from a second source without telling the DSCR lender, because that can turn a clean file into one with unexplained funds.
Where the Rule Breaks
The 100% borrowed down payment. Some programs fail this outright. It is a common reason a promising file gets pended.
Passing DSCR but losing money. Say a rental clears around 1.2x on rent against its own PITIA. It still has to carry the line payment out of your pocket, plus repairs and vacancy. The file can qualify and still run negative once everything is stacked.
Prepayment penalties. Some DSCR loans carry a step-down prepayment penalty. If your plan is to refinance and repay the line early, that penalty makes the exit costlier. Read the prepayment terms before you rely on a refinance as the way out.
No built-in exit. The line has no end date that fits your rental plan. Investors usually repay it from cash flow, from a sale, or from a refinance of the rental. A refinance only works if the rental has enough value and coverage. A cash-out refinance on a standard rental tops out around 75% LTV across most of the network. On short-term-rental collateral the cash-out ceiling is 70%. Seasoning of about 6 months is the common expectation, so the exit is not instant.
Payment shock. The CFPB notes that payments are often significantly higher once the repayment period starts, and in some cases the whole balance comes due when repayment begins. Lines usually carry variable pricing, so payments can change month to month. The CFPB’s HELOC brochure adds that some plans allow interest-only payments during the draw, and that payments can change even if you draw nothing more.
Scaling. Each line-funded purchase adds a payment. Repeating the strategy strains the portfolio faster than the rent grows. A borrower is also limited to three lines, and one who owns more than 15 financed properties is not eligible.
High DTI. DSCR avoids a borrower DTI test on the purchase. The line does not. A high DTI can stall the line even when the rental itself is strong.
Short-term rentals. If the target is a short-term rental, DSCR leverage differs. Purchases run to 75% LTV, refinances around 70% and cash-out 70%. Expect a 640 or better score and about 12 months of hosting history. 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. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Stress-Testing the Plan
Run three failure cases before you commit.
| Scenario | What changes | What to check |
|---|---|---|
| Base case | Rent covers PITIA | Both payments covered |
| Line cost rises | Variable pricing moves | Can you carry it? |
| Vacancy | Rent stops | Reserves outside the draw |
| Closing slips | Draw sits idle | Interest while you wait |
A plan that only works at current pricing and full occupancy is thin. Keep reserves in unborrowed cash. A line draw is a liability, not a cushion.
Is a HELOC the Right Tool?
Use a line when your gap is modest, your credit and equity are strong, and the DSCR program accepts documented borrowed funds. It also fits when the rental has enough rent coverage to carry its own debt without help from you.
Look elsewhere when the plan needs 100% borrowed funds, when your DTI is already near the ceiling, or when the only collateral is a property held in an LLC. A larger down payment from savings, a lower-leverage purchase or a different cash-out route may fit better. The same borrower on different collateral can reach different answers, so compare structures before you pick one.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
A Pre-Application Checklist
1. Confirm with your broker whether the target DSCR program accepts documented line draws.
2. Confirm whether the program requires a minimum of your own funds, and whether any borrowed cash counts as reserves.
3. Calculate the shortfall, including closing costs, and size the line to it, remembering the 75% draw at closing.
4. Check that the collateral can hold title under the line’s rules: individual or revocable living trust, not an LLC.
5. Open the line, draw the cash and park it in an account in your name.
6. Gather the line’s closing documents, draw confirmation and bank statements.
7. Verify the rental’s coverage, and run your own cash flow with both payments included.
8. Keep reserves in unborrowed cash.

Frequently Asked Questions
Can a HELOC be the whole down payment?
Sometimes, but it is the weakest version of the plan. Programs differ, and some cap borrowed funds or require a share of your own seasoned cash. A plan that is 100% borrowed can fail on that point alone, so confirm the rule before drawing anything.
Does the HELOC payment count in the DSCR ratio?
Generally no. DSCR divides the new property’s rent by that property’s PITIA. Your line payment sits outside the ratio, but it still comes out of your monthly cash flow, and the line lender counts it when it reviews you.
Can HELOC money also count as reserves?
Often not. Down payment and reserves are separate requirements, and borrowed cash frequently cannot fill both. Reserves commonly run around 6 months of PITIA, though they vary by lender, leverage, loan size and transaction type.
Can I get the line after I’m under contract?
That is risky. A line takes time to set up, and the DSCR lender has to confirm it will accept borrowed funds first. Raise the plan before you go under contract.
Can I use a line on a rental I already own?
Yes, but it is harder. On Lendmire’s network, an investment property line caps at 70% CLTV and $500,000 total, with a 700 minimum credit profile. Eligibility is subject to lender guidelines and full file review.
