The Quick Read: A home equity line on the house you live in can supply the down payment on a rental, but two separate lenders must each approve you. The line lender looks at your equity, credit, and debt load. The rental lender then checks where the down payment came from and whether the property’s rent covers its own payment.
- On a primary residence, the combined loan-to-value ceiling on our network reaches 90%, and only at a 720 or better credit profile.
- A line secured by an investment property tops out at 70% combined loan-to-value, with a 700 minimum credit score and a $500,000 maximum line.
- Whether the purchase lender accepts borrowed down payment funds depends on the program, so ask before you draw.
- Rental coverage and positive cash flow are different things. Your HELOC payment comes out of your pocket either way.
Two Ways to Use a HELOC for a Rental Purchase
You can borrow against the home you live in, or against a rental you already own. The title of this article points to the first option, but the second exists and follows different rules. Choosing between them is the first decision, and most investors never frame it that way.
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.
| Factor | Line on your home | Line on an existing rental |
|---|---|---|
| Collateral at risk | Your primary residence | A rental you own |
| Network CLTV ceiling | Up to 90% (720+ credit only) | 70% |
| Credit floor | 600 program floor | 700, no tier below it |
| Maximum line | $750,000 | $500,000 |
| Title | Individual or revocable trust | Individual or revocable trust |
Combined loan-to-value (CLTV) adds your first mortgage and the line together, then divides by the home’s value. Those figures describe the select wholesale lenders Lendmire works with, and every file is reviewed individually. Broader market surveys report different numbers for equity lines, and those describe the market at large, not this network.
The line on your home usually offers more leverage and a larger limit. It also puts the house you sleep in behind the rental purchase. A line on a rental keeps your residence out of it, but it caps at a lower CLTV and demands a higher credit score. Both need a property you already own. You cannot open a line on the rental you are about to buy.
Key Terms Defined
HELOC: A home equity line of credit is a revolving line secured by property you already own. You draw what you need, up to a limit.
CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the property’s value. It measures how much of the home is already pledged.
DSCR (debt service coverage ratio): A rental’s monthly rent divided by its full monthly payment. Above 1.00, the rent covers the payment.
PITIA: Principal, interest, taxes, insurance, and any association dues. It is the full monthly payment of the rental.
DTI (debt-to-income ratio): Your monthly debt payments divided by your monthly income. HELOC underwriting uses it. DSCR underwriting leans on the property instead.
Seasoning: The waiting period a lender wants between two events, such as buying a property and refinancing it.
Reserves: Liquid money left over after closing, usually counted in months of PITIA.
Non-QM: Loans that fall outside standard owner-occupied mortgage rules. DSCR loans for investors usually sit here.
How a HELOC Actually Works
A HELOC is an open-end line of credit. The Consumer Financial Protection Bureau describes it as a line you can borrow against repeatedly, and it defines equity as your home’s value minus what you owe on the mortgage. It also warns that if you fall behind or cannot repay on schedule, you could lose your home. That warning is the whole risk in one sentence.
The structure on our network is specific. Investment lines run a 5-year interest-only draw period followed by a 25-year fully amortizing repayment period. Primary residences and second homes can instead use a 3-year draw followed by 17 years of repayment. Texas shortens both structures, but the logic is the same.
Three more mechanics matter for an investor:
- At least 75% of the line is drawn at closing. This is not a standby reserve you can leave untouched.
- Pricing floats during the draw and the repayment period. It never converts to fixed. The CFPB’s HELOC booklet explains that lenders disclose variable-rate terms and may freeze or reduce a line in some circumstances.
- After closing, additional draws start at a $1,000 minimum on the 5-year program.
Think of it as a big, variable-cost loan with a payment that starts small and steps up when repayment begins. Plan for the step.
Requirements Lenders Check on the Line
The HELOC lender cares about you and the home. The rental you plan to buy matters very little here. Across the programs we place files with, the main checks look like this.
Credit. The program floor is 600, with a single-bureau score model keyed to the primary wage earner. The report can be no more than 90 days old at closing. On an investment line the floor rises to 700, and 720 and 700 both reach the same 70% CLTV. Credit above 700 buys eligibility, not extra leverage.
Debt-to-income. The maximum is 50%. It drops to 45% for credit profiles between 600 and 679, and any ratio above 45% requires at least a 680 score. The lender reviews your file on the interest-only payment calculated on the maximum draw, even if you plan to draw less.
Valuation. Lines at or below $500,000 ordinarily use an automated valuation, with no traditional appraisal. A full appraisal is required on every line above $500,000. You can also ask for one in any case.
Line size. Lines run from $25,000 to $750,000 (Michigan’s floor is $10,000). A line above $500,000 is for primary residences only. It needs a credit profile of 700 or better (720 on the 5-year draw program) and caps at 75% CLTV.
Derogatory history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by program on primary residences, with one program seasoning a foreclosure over 7 years and the other declining it entirely.
Property. Single-family, 2-4 units, PUDs, townhomes, and condos, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural zoning are not.
Exposure. A borrower is limited to three lines. Someone with more than 15 financed properties is not eligible.
These are guidelines from select wholesale lenders, never a promise. Availability for HELOC placements is limited to Lendmire’s 16 full-service states, which is narrower than its DSCR footprint of 41 markets, including Washington, D.C.
How Much Can Your Equity Support?
Your usable line is the ceiling CLTV minus your existing mortgage, each measured as a share of the home’s value. Here is the shape of it, using percentages only. Say your first mortgage equals 60% of your primary residence’s value. If you qualify for the 90% ceiling (720 or better), the line could add at most 30 points of value. If your profile only supports a lower ceiling, the room shrinks fast.
That is a ceiling, not a recommendation. Drawing the maximum means close to 100% financing across two properties, and a fully borrowed down payment can fail with some purchase programs on that point alone.
The same math applies to a line on a rental, but the ceiling is 70% CLTV. With a first mortgage already near that number, there may be no room at all.
What the Rental Lender Does With the Draw
The rental lender treats a HELOC draw as borrowed money, and it wants proof of where the cash came from. This step catches more investors than any other.
1. You draw the funds into your own account. The deposit should sit on bank statements so the underwriter can trace it to the line.
2. You provide the paper trail. That means recent statements, the HELOC statement, and a written explanation of large deposits.
3. The lender sorts the funds into a bucket. Down payment, closing costs, and reserves are separate tests, and borrowed money may count toward one but not another.
Programs sort into three camps. Some accept documented line proceeds toward the down payment. Some cap the borrowed share. Some require part of the down payment to come from your own unborrowed funds. Gift funds and unsourced cash follow their own rules, which vary by program.
Reserves deserve their own warning. Reserves are commonly around 6 months of PITIA. Conservative rate-and-term files at modest leverage under $1,500,000 can see them waived, and loans above that size typically step up to about 9 months. An undrawn line is not cash. Keep reserves outside the borrowed money, and confirm acceptance with the purchase lender before you pull a dollar. Sequence matters: open and fund the line first, then go under contract.
Yahoo Finance confirms that you can use a HELOC for a down payment on a second home or investment property. It also suggests the approach suits owners with healthy reserves and a plan to pay the line off or refinance within a short window. That matches what we see.
How the Two Loans Qualify Together
You face two tests, and they measure different things. This is where investors confuse “approved” with “profitable.”
The HELOC lender looks at your DTI. The rental lender, on a DSCR loan, looks at the property. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The HELOC payment generally sits outside that ratio, though a lender may still look at your overall debt picture. On a conventional loan, by contrast, the HELOC payment counts in your DTI like any other debt.
Here is what the rental side looks like on our network. Most files land at 75%-80% LTV on a purchase, which means 20%-25% down. Select high-leverage programs reach 85% LTV on a purchase (15% down) with roughly a 700+ score. Coverage of 1.00 is where many select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Credit floors run about 660 on most programs, a 620 floor exists in parts of the network, and 700+ unlocks the strongest leverage tiers. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders).
A bigger down payment lowers the monthly payment and can lift the coverage number. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
One property type is simply not offered on DSCR loans: manufactured homes (single- and double-wide), log homes, and barndominiums.
Clearing 1.00 is not positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. Add the HELOC payment and the real picture can turn negative while the DSCR looks fine. Our complete DSCR loans guide walks through the full calculation.
Where the Rule Breaks
The general rule is that a HELOC on your home can fund the down payment. These cases bend it.
Your rental is held in an LLC. A DSCR loan can close in an LLC, subject to lender program eligibility. A HELOC cannot. On our network, only an individual or a revocable living trust can hold title for a line. An LLC, corporation, partnership, or irrevocable, blind, or land trust cannot. If a property is already deeded to an LLC, it needs a vesting change, or a DSCR cash-out refinance instead.
You rent out the house the line sits on. The CFPB’s consumer materials note that renting your home to others may be prohibited under the terms of a line. House-hackers should read the occupancy language before they sign.
The line gets frozen. Lenders can freeze or cut a line if the home’s value falls or your finances worsen. If you were counting on later draws to cover rehab or reserves, that is a real risk.
The property is listed for sale. A property listed for sale, or within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
The line is fully borrowed. Putting 100% of the down payment on a HELOC can fail with some purchase programs on that alone.
You plan a quick exit. Many investors repay the line with a later cash-out refinance on the rental, and most programs expect about 6 months of seasoning before that refinance. Cash-out on a standard rental tops out around 75% LTV across most of the network. Check for a prepayment penalty on the purchase loan first, because it can block the exit.
Stress-Test the Plan Before You Draw
Run three bad scenarios on paper before you commit.
| Scenario | What changes | What to ask |
|---|---|---|
| Rental sits vacant | Both payments fall on you | Can your income carry them alone? |
| Home value dips | Line may be frozen or reduced | Can you finish the plan without it? |
| Repayment period starts | Payment steps up | Is the payoff plan in place? |
Add two more questions. Do your reserves sit outside the borrowed money? And does the rental still work if coverage lands near the low end of what your program allows?
When the Answer Leans Yes, and When It Doesn’t
It leans yes when you have meaningful equity, a credit profile at or above the tier you need, reserves in cash, and a rental that covers its payment with room to spare. It also helps to have a defined plan to pay the line down or refinance it.
It leans no when the line would fund close to 100% of the down payment, when your income only just carries your current debts, or when losing the line would break the plan. It also leans no when the rental’s coverage is thin and the HELOC payment would make cash flow negative.
Honestly, this is a toss-up for many investors. The equity is real, and the leverage is tempting. But using your residence to buy a second property doubles what a bad year can cost you.
Frequently Asked Questions
What credit score do I need for a HELOC to fund a rental down payment?
It depends on the collateral. The program floor is 600, and a home line at 720 or better reaches the highest ceiling. A line secured by an investment property requires at least 700. Most DSCR purchase programs then want around 660 on the rental side, with 700+ unlocking the strongest leverage.
Does the HELOC payment count in my DSCR?
Generally no. The ratio compares the rental’s rent to the rental’s own PITIA. A lender may still review your overall debt picture, and the payment still comes out of your pocket. Passing the ratio does not make the deal cash-flow positive.
Can my LLC take out the HELOC?
No. Only an individual or an inter vivos revocable living trust can hold title for a line on our network. The DSCR loan on the rental can be in an LLC, depending on program guidelines. Plan the HELOC in your personal name.
Can I use the line for reserves too?
Borrowed funds are commonly excluded from reserves, and an undrawn line is not cash. Treat reserves as a separate test and keep them in your own liquid funds. Confirm the exact treatment with the purchase lender.
Does every lender accept HELOC funds for the down payment?
No. Programs vary. Some accept documented proceeds, some cap the borrowed portion, and some require part of the down payment to be unborrowed. Ask before you draw.
