Best HELOC Program to Fund the Down Payment Before Selling Your Current Home

The Quick Read: The right fit is a standalone line on your current home, opened before you list, sized to the down payment and closing costs, accepted by the lender funding your rental purchase, and repaid from the sale proceeds, with the overlapping payments tested first. No single program wins for everyone. The best program for your situation depends on your credit profile, the equity you hold, and how the rental lender treats borrowed funds.

• The line is approved against you and your home. The rental loan is approved against the property and its rent.
• Open the line before the home is listed. In several states the network serves, a property listed within the past 60 days is ineligible.
• Primary-residence lines reach 90% combined loan-to-value only at a 720 credit profile. Lines on investment properties stop at 70%.
• Clearing 1.00x on the rental does not make it cash-flow positive. You still carry the old mortgage and the line payment.
• Size the line to what you need. At least 75% of it is drawn at closing.

What Is Actually Happening in This Move?

You are using two separate loans. One borrows against the home you already own. The other buys the rental. The first gives you cash, and the second decides whether that cash is welcome.

That second decision is where most plans succeed or fail. A HELOC places no restriction on how you spend the money. The purchase lender, however, sets its own rules on borrowed down payments. Some programs accept them with documentation. Others cap the borrowed share or want part of the cash to come from your own seasoned funds. A plan built on 100% borrowed money can fail on that point alone.

So the “best program” question splits in two. First, which equity line fits your home and credit. Second, which rental loan will accept what that line produces. A broker who shops several wholesale lenders can match both halves at once. Lendmire works that way, arranging financing through select lenders in its wholesale network rather than lending directly.

Availability is narrower for the line than for the rental loan. HELOCs through Lendmire run in 16 full-service states, while its DSCR investor programs cover 41 markets, including Washington, D.C.

How Underwriting Treats It, Step by Step

Each step below has its own approver, so walk through them in order.

1. Open the line before you shop or list. Lenders don’t usually approve home equity financing once a home is already on the market, which is why it pays to open the line before you list or start shopping. On our network, the same logic shows up as a listing-status rule in several states.

2. Qualify the line. The line lender reviews your credit, your combined loan-to-value (CLTV), and your debt-to-income ratio (DTI). CLTV is your first mortgage plus the new line, divided by the home’s value. DTI is monthly debts divided by monthly income. On our network, the maximum DTI is 50%. It drops to 45% for credit profiles from 600 to 679. Anything above 45% needs at least a 680 score. The test uses the interest-only payment on the maximum draw, so a large line can hurt even if you draw little.

3. Value the home. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal. A higher CLTV may trigger a second valuation, and you can request a full appraisal anyway. Every line above $500,000 needs one.

4. Draw and document. The cash lands in your own account. Lenders funding the rental treat down payment, closing costs, and reserves as separate buckets. Borrowed funds are commonly accepted toward the down payment and closing costs with a paper trail, but they are often excluded from reserves. Some lenders also want a large deposit to sit for a few months first.

5. Close the rental. The DSCR lender compares the rent to the property’s full monthly obligation, known as PITIA (principal, interest, taxes, insurance, and association dues). Your HELOC payment sits outside that ratio, and personal DTI is generally not part of a DSCR review. A bigger down payment shrinks the new loan and can lift the coverage number.

6. Sell and repay. The CFPB’s HELOC booklet says a sale generally requires you to pay the line off in full. The sale proceeds retire it. If the home sells slowly, the line keeps costing you.

What Makes a Program the Right Fit?

A good program fits your file on five points: lien position, occupancy, leverage tier, draw structure, and valuation. The network has a standalone line that can sit in first or second lien position. At least 75% of it is drawn at closing, and pricing floats through both the draw and repayment periods. It never converts to fixed.

Two draw structures exist on primary residences and second homes. One is a 3-year interest-only draw followed by a 17-year repayment period. The other is a 5-year draw followed by a 25-year repayment period. Investment lines run only the 5-year/25-year structure. Yahoo Finance reports a typical market draw period of 10 years with repayment over about 20. The network structures above are the ones that apply to your file.

Most buyers in this situation use a primary-residence line. Here is how the ceilings run by credit tier, subject to lender guidelines:

Read the first row carefully. The 90% ceiling exists only at a 720 credit profile. Scores of 700 and 720 and above can also reach 75% CLTV on a line up to $750,000. A line above $500,000 is primary-residence only, requires a 700 credit profile or better (720 on the longer-runway program), caps at 75% CLTV, and needs a full appraisal.

Lendmire places files with two wholesale programs, so the terms differ slightly. The higher-leverage program caps combined exposure at $2,000,000 across three lines. The longer-runway program caps it at $750,000 and applies stricter tradeline and housing-history standards. Both exclude manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning.

A Worked Example in Percentages

Say you own a home with a first mortgage equal to 50% of its value. Your credit sits in the 700 range. On the table above, your cap is 85% CLTV. That leaves room for a line worth up to about 35% of the home’s value, subject to the $500,000 line cap and the valuation.

Now picture the rental. You plan to buy at 75% loan-to-value, which means 25% down, plus closing costs. Size the line to that total, not to the full 35%. At least 75% of whatever limit you choose gets drawn at closing, so an oversized line means interest-only payments on cash you never needed. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

Next, stress-test the carry. For a stretch of time you will owe the old mortgage, the line payment, and the new rental loan. The rental’s rent covers its own payment if coverage is above 1.00x. It does not cover the line. Picture two outcomes: the old home sells on plan and the line disappears, or the sale drags and you carry all three obligations for months. Run both before you draw a dollar.

Which Step Comes First? A Timing Table

The cleanest path is to open the line, get preapproved for the rental with the line disclosed, draw what you need, and make an offer that does not depend on selling first. Redfin’s buy-and-sell guide describes that non-contingent offer as the main payoff of buying first.

Where the Rule Breaks

The fully borrowed down payment. Some rental lenders require part of the cash to be your own seasoned money. If every dollar of your down payment comes from the line, a lender with a borrowed-share cap may decline. Ask before you draw, not after.

LLC-held homes. The line needs title held by you individually or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead, subject to program terms.

Keeping the old home as a rental. The CFPB’s overview of how a HELOC works says you can fall behind on the payments and risk losing the home, and the booklet above notes that a line’s terms may prohibit renting out the property. Read your line terms before you convert. If you do keep the home as a rental, a new line on it is an investment-property line, which is a different product. Investment lines top out at 70% CLTV and $500,000, require a 700 minimum, and use only the 5-year/25-year structure.

Credit and DTI. The rental loan may ignore your DTI, but the line lender will not. A borrower who clears a DSCR review easily can still fail the line on income.

Credit floor. The program floor is 600. Second homes floor at 640 and investment properties at 700. Sub-640 borrowers are limited to single-family primary residences on the longer-runway program, with a clean 12-month housing history.

Property type and exposure. Single-family, 2-4 unit, PUD, townhome, and condominium properties, including non-warrantable condos, are eligible. A borrower is limited to three lines, and anyone with more than 15 financed properties is not eligible.

Bridge loans. A bridge loan is short-term with interest-only payments, and the old home is usually the repayment source. It is a different tool from a HELOC. Some investors prefer a bridge loan when the home is already listed, since a HELOC may no longer be available.

What the Rental Loan Needs From Its Side

Funding the down payment is only half the test. The rental still has to clear the DSCR review. Most purchase files land at 75% to 80% loan-to-value, which means 20% to 25% down. Select high-leverage programs reach 85% with a score around 700 or higher. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

Coverage of 1.00x is where many select programs start. A separate select-lender path takes coverage below 1.00x, with leverage and terms adjusted. A stronger ratio opens better pricing and leverage. Credit floors of 620 exist in parts of the network, most programs want around 660, and 700 or better unlocks the strongest tiers. Reserves vary by lender, leverage, loan size, and transaction type, and are commonly around 6 months of PITIA.

A bigger down payment lowers the new payment and can lift coverage, but it never erases leverage caps, credit floors, reserve rules, or property eligibility. Clearing 1.00x also does not mean positive cash flow, because repairs, vacancy, management, and utilities sit outside the calculation. Lendmire’s complete DSCR loans guide walks through the coverage math in detail.

Key Terms Defined

CLTV: Combined loan-to-value, meaning your first mortgage plus the new line, divided by the home’s value.

Draw period: The stretch when you can borrow from the line, usually with interest-only payments.

Repayment period: The stretch after the draw period when the full balance is paid down.

DTI: Debt-to-income ratio, meaning monthly debts divided by monthly income.

PITIA: Principal, interest, taxes, insurance, and association dues on the new property.

Seasoning: The time money has sat in your account before a lender will count it as your own.

Making the Decision

Start with three questions. Do you have enough equity to reach the down payment within the CLTV cap for your credit tier? Will the rental lender accept the borrowed share? Can you carry three obligations if the sale takes longer than planned?

If the answer to all three is yes, open the line before listing, size it tightly, and draw only what the purchase needs. If any answer is no, consider a bridge loan, a sale contingency, or waiting.
