The Quick Read: Usually yes: a HELOC on your current home can fund the down payment on a rental, but only if the line is already open before you list the home, the purchase lender accepts documented borrowed funds, and the new deal can carry the old mortgage, the HELOC, and the new loan at the same time. The order of events matters more than the equity itself.
- Open the line first. A lender generally won’t approve a new line once the home is on the market.
- Ask the purchase lender before you draw. Borrowed down payments are program-dependent, and reserves are usually a separate bucket.
- Expect close to 100% financing. Borrowed down payment plus a purchase loan leaves little of your own money in the deal.
- Plan for the overlap. You may carry three obligations at once until the old home sells or the line is repaid.
What Is a HELOC, and Why Would an Investor Draw on One?
A HELOC, or home equity line of credit, is a revolving credit line secured by your home. You borrow against equity, which is the home’s value minus what you owe on it. You draw cash as needed, up to the line’s limit.
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.
For a seller-investor the appeal is simple. Your equity is locked in a house that hasn’t sold yet, and the next deal won’t wait. A line lets you tap that equity, make an offer without a sale contingency, and keep your savings intact.
The catch is equally simple. The line is borrowed money, and your current home secures it. NerdWallet’s guide to buying before selling describes the same basic play: draw on the current home’s equity to fund the next down payment.
Timing: Open the Line Before You List
The line has to exist before you need the money. Lenders generally won’t approve a HELOC after the home is listed for sale. Approval can also take longer than a first mortgage, so starting early is part of the plan.
On the home equity lines our wholesale network places, the same logic shows up in the guidelines. In a number of the 16 states where we place these lines, a property that is listed for sale, or was listed within the past 60 days, is ineligible. Listing first and borrowing second is the order that fails.
Here is a clean timeline:
1. Decide you may buy before you sell.
2. Apply for the line while the home is still off the market.
3. Draw the funds you need.
4. Make the offer and close on the new property.
5. List and sell the old home, or keep it.
Skip step two and the rest gets harder.
How the Sequence Works, Step by Step
Step 1: Ask the purchase lender first. Before you open or draw anything, confirm that the DSCR program you plan to use accepts borrowed funds for the down payment and closing costs. DSCR, or debt service coverage ratio, compares a rental’s income to its monthly payment. The loan is a business-purpose investor loan, so it is reviewed differently from a standard owner-occupied mortgage.
Step 2: Size the line. Cover the down payment, closing costs, and a cushion. Do not oversize it. On the home equity lines in our network, at least 75% of the line is drawn at closing, so a bigger line means a bigger drawn balance from day one.
Step 3: Draw and document. Borrowed down-payment money is verified like any other source. Expect the lender to ask for the line agreement, recent statements, and proof that the draw landed in your account. Large unexplained deposits trigger source-of-funds questions. Some lenders also want the money to sit in the account for a period, which is called seasoning. That habit varies by lender, so ask rather than assume.
Step 4: Exit the line. If you sell the old home, the line is generally repaid from the sale proceeds. If you keep the old home, the line stays and you keep paying it. Many lines allow interest-only payments during the draw period and then shift to principal repayment. That step-up catches people.
What the Network’s Home Equity Lines Allow
The home equity lines we broker are standalone lines, placed in first or second lien position, through select wholesale partners. Our brokerage is never the lender, and every figure below is subject to lender guidelines and full file review. They are not a commitment to lend.
Ceilings depend on how the home is used. CLTV, or combined loan-to-value, adds your first mortgage and the new line together and divides by the home’s value.
| Occupancy | Max CLTV | Minimum credit | Max line |
|---|---|---|---|
| Primary residence | 90% only at 720+ | 600 | $750,000 |
| Second home | 90% only at 720+ | 640 | $500,000 |
| Investment property | 70% | 700 | $500,000 |
The 90% figure applies only to lines up to $500,000. On a primary residence, 85% CLTV is available from roughly 660 to 719, and lines up to $750,000 cap at 75% CLTV. These ceilings step down as credit drops.
Several other points shape the plan:
- Draw structure. Primary and second-home lines come in two structures: a three-year interest-only draw followed by a 17-year repayment, and a five-year draw followed by a 25-year repayment. Investment lines run the five-year structure only. Pricing floats and never converts to fixed.
- Debt-to-income. DTI, the share of your monthly income that goes to debt payments, can run up to 50%, and 45% for credit profiles from 600 to 679. The line is qualified on the interest-only payment at the maximum draw, not on what you actually draw.
- Valuation. Lines at or below $500,000 ordinarily use an automated valuation. A full appraisal is required above that size.
- Title. The individual borrower or a revocable living trust holds title. An LLC cannot. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance may be the better route, subject to lender program eligibility.
- Availability. These lines are placed in 16 states, which is narrower than our 41-market DSCR footprint.
Will the DSCR Lender Accept Borrowed Funds?
It depends on the program. Across our network, borrowed funds with clear documentation is commonly accepted for the down payment and closing costs. Some programs cap the borrowed share. Some lenders want a portion to come from your own funds. That is why the first call goes to the purchase lender, not the home equity lender.
Reserves are a separate question. Reserves are the cash left in the bank after closing, commonly around six months of PITIA. PITIA is principal, interest, taxes, insurance, and association dues. Borrowed money may count toward the down payment but often cannot double as reserves. Reserve rules also vary by lender, leverage, loan size, and transaction type, so confirm yours before you commit.
Large retail banks are a different story. Big banks writing owner-occupied loans may insist that a down payment come from unborrowed funds. Investor programs are often more flexible, but flexible is not unlimited.
Does the Rental Still Clear the Coverage Test?
Here is the part people miss. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The HELOC payment is not in that ratio. The ratio looks only at the new property’s rent against its own PITIA.
So the number can look clean while your real position is stretched. Picture an investor buying a rental at 75% LTV on a purchase, with the other 25% funded by a HELOC on the old home. The rent clears roughly 1.2x on the new loan alone. That sounds comfortable. But the total debt against the new property is close to 100% of its price, and the HELOC payment, plus the old mortgage, sits outside the ratio. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Run the numbers this way, as a modeled assumption rather than a market fact. Take the new loan’s coverage, then add the HELOC payment and the old mortgage payment on top. If the combined picture only works when the old home sells on schedule, the deal depends on the sale, not on the rental.
A few program realities help frame this:
- On a purchase, most files land at 75% to 80% LTV, which means 20% to 25% down. Select high-leverage programs reach 85% LTV on a purchase with roughly a 700 or better score.
- 1.00 is where many select programs start for coverage. A separate path through select lenders in the network takes coverage below 1.00, with leverage and terms adjusted.
- Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation.
- A larger down payment lowers the new loan’s payment and can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility.
Our complete DSCR loans guide covers the full set of purchase parameters. The strongest files clear two tests: enough equity and enough rental coverage.
The Exceptions That Break the Plan
A listed home. If the old home is already on the market, a new line may be unavailable. NerdWallet lists a bridge loan as the alternative. A bridge loan is short-term financing against the home you are selling, and it usually costs more and carries tighter terms than a line.
A frozen or reduced line. Lenders generally reserve the right to freeze or cut a line if home values fall or your finances worsen. Draw what you need before the contract, and do not count on undrawn availability. Money you haven’t pulled isn’t money you have.
Payment step-up. An interest-only draw period is cheap while it lasts. When the repayment period begins, the payment rises because principal joins it. Know the date.
Renting the old home. Some lines restrict renting the home to tenants. If you plan to keep the old home as a rental, read the line’s terms first. A line on a home you already rent is underwritten as an investment line, with the 70% CLTV ceiling and the 700 credit floor shown above.
A slow sale. The line is repaid on a sale. If the home sits, you carry both loans. That is the scenario to stress test before you borrow.
Counting on the old home’s equity twice. The same equity can’t fund the new down payment and also pay off the old mortgage if the price drops. Build in a cushion for price cuts and selling costs.
Risk: Your Home Secures the Line
A HELOC is borrowed money, and the CFPB’s explainer on home equity lines of credit is blunt about it. Falling behind could cost you the home that secures the line. That includes the case where the borrowed funds went into a rental that later underperforms.
Honestly, this one is a toss-up for many investors. The strategy rewards the person who has a tested sale timeline, a rental with real margin, and a cash buffer. It punishes the person who treats a credit line as free money.
When Not to Do It
Skip the HELOC approach if any of these fit:
- Your old home is already listed or about to be.
- The new rental only works at close to 100% financing with no slack.
- You have no reserves outside the borrowed funds.
- The old home’s sale depends on one buyer or a rising market.
- Your credit sits near a program floor, so the line may be capped or priced harshly.
- The old home sits in an LLC or an ineligible property type. Manufactured homes, co-ops, condotels, log homes, and commercial or mixed-use properties are not offered on these lines.
HELOC vs. the Alternatives
| Option | Fits when | Main tradeoff |
|---|---|---|
| HELOC on old home | You have equity and haven’t listed | Line must exist before listing |
| Bridge loan | Home is listed and sale is near | Short-term; usually costs more |
| Cash-out refinance on old home | You are keeping the old home | Resets the first mortgage |
| Sale contingency | Seller will wait on your sale | Weaker offer |
If you plan to keep the old home, a cash-out refinance can replace the line with one loan. A BiggerPockets Rookie episode compares a HELOC with a cash-out refinance for the next down payment.
Key Terms Defined
HELOC: A revolving credit line secured by your home, with a draw period followed by a repayment period.
CLTV: Combined loan-to-value, which adds every loan secured by the home and divides the total by its value.
DTI: Debt-to-income ratio, the share of monthly income that goes to debt payments.
DSCR: Debt service coverage ratio, a rental’s income compared with its monthly payment.
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly housing obligation.
Seasoning: The time borrowed or deposited money must sit in an account before a lender treats it as settled.
Frequently Asked Questions
Can I open a HELOC after my home is listed?
Generally not. Lenders usually won’t approve a new line once the home is on the market, and in a number of states our network treats a recently listed home as ineligible. Open the line before you list, even if you are not sure you will use it.
Does the HELOC payment count against me?
On the home equity lines our network places, yes. The payment counts in DTI, calculated on the interest-only payment at the maximum draw. On a DSCR purchase, the loan itself qualifies primarily on the property’s rental coverage, but the HELOC still affects your cash flow and your ability to qualify for the line.
Can borrowed money also cover my reserves?
Often not. Borrowed funds are commonly accepted for the down payment and closing costs with documentation, but many programs exclude them from reserves. Plan separate liquid reserves, and confirm the rule with your purchase lender.
What happens to the HELOC when the old home sells?
The line is generally repaid in full from the sale proceeds. If you keep the home as a rental instead, the line stays in place and you keep servicing it. Check whether the line’s terms restrict renting before you rely on that path.
Can I use a HELOC on an investment property?
Yes, within limits. On the network’s investment-property lines, the ceiling is 70% CLTV, with a 700 minimum credit profile and a $500,000 maximum line. An LLC cannot hold title on these lines.
