Best HELOC Program to Buy a New Home Before Selling

The Quick Read: The right HELOC setup is one opened on your current home before it is listed, sized to the equity and occupancy involved, and paired with a purchase loan that tests the new property’s rent instead of your personal debt-to-income ratio, subject to lender guidelines. No single program wins on every file.

• Open the line before the home is listed. The network’s equity lines are ineligible on a home that is listed or was recently listed in some states, including NC, PA, TN, TX and WA.
• On an investment property, the network’s equity line tops out at 70% CLTV. Primary-residence lines reach 90% CLTV only at a 720-or-better credit profile.
• Most lines are substantially drawn at closing, so plan for a real line payment, not a standby cushion.
• A DSCR purchase loan leaves the line payment out of the coverage ratio. That does not make the payment disappear from your cash.
• Lendmire is a broker. It matches the file to a wholesale lender and never lends itself.

What “Best” Means on This Kind of File

The best program for your situation depends on four things: the occupancy of the home you own, your credit profile, how much leverage you need, and how the next purchase will be underwritten. Anyone who names one winner without those inputs is guessing.

Lendmire is a mortgage broker. It works with a network of wholesale HELOC lenders, shops the scenario across them, and matches the file to a program. It does not rank or recommend lenders. What follows is how those lenders think, so you can walk in prepared.

Two tests run on every buy-before-you-sell file. The first is the line on the home you own. The second is the loan on the home you are buying. Investors tend to polish the first and neglect the second. The second one decides whether the deal holds together.

How the Buy-Before-You-Sell Play Works, Step by Step

The play is simple on paper. You borrow against equity in the current home, use the cash for the down payment and closing costs on the next property, then repay the line from sale proceeds. Here is the sequence as it actually runs inside a file.

1. Open the line first. Many lenders will not open a new line on a home that is already listed. In NC, PA, TN, TX, and WA, the network’s equity-line programs treat a home that is listed, or was recently listed (a 60-day lookback applies), as ineligible. Sequence matters more than any other choice here.

2. Size the line to the equity. The line is limited by combined loan-to-value, meaning the first mortgage plus the new line against the home’s value. Credit profile sets the ceiling. More on that below.

3. Draw and document. Pull the funds into your own account and keep the trail. A purchase lender will want to see where the down payment came from.

4. Qualify the new purchase. This is the step that breaks files. A DTI-tested loan counts the line payment and the old mortgage against your income. A DSCR loan tests the new property’s rent against its own payment.

5. Sell the old home and repay the line. The line is generally paid off at the sale closing, and the settlement statement reconciles it.

Steps 1 and 4 cause most of the damage. The first fails on timing. The second fails on the wrong loan type.

What the Network’s HELOC Lenders Look For

On a primary residence, the ceiling reaches 90% CLTV. That figure exists only at a 720-or-better credit profile, on lines up to $500,000. Lines above $500,000, up to the $750,000 maximum, cap at 75% CLTV and need a credit profile of 700 or better (720 on the longer-runway program). Lower credit tiers step down: for example, 640-plus scores sit at 80% CLTV on a primary residence, and the program floor is 600.

The ceiling depends on how the home is occupied, so read this table by row.

A few more mechanics that matter on a buy-before-you-sell file, all subject to lender guidelines and full file review:

• Line size. Lines run from $25,000 to $750,000. A line above $500,000 is primary-residence only, caps at 75% CLTV, and needs a full appraisal. The credit requirement there is 700 or better (720 on the 5-year-draw, 25-year-repayment structure).
• Structure. Two draw structures exist on primary residences and second homes. One has a 3-year interest-only draw with a 17-year repayment. The other has a 5-year interest-only draw with a 25-year repayment. Investment lines use the 5-year structure only.
• Draw at closing. At least 75% of the line is drawn at closing. Pricing floats across the draw and repayment periods and does not convert to fixed.
• Valuation. Lines at or below $500,000 ordinarily run an automated valuation. Above $500,000, a full appraisal is required.
• DTI. Maximum 50%, and 45% for credit from 600 to 679. The test uses the interest-only payment on the maximum draw.
• Title. The individual borrower or a revocable living trust holds title. Not an LLC.
• Availability. The equity-line programs cover Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the 41-market DSCR footprint.

Texas deserves a flag. A Texas primary residence is a homestead and caps at 80% combined loan-to-value, so the higher matrix tiers never apply there. Texas second homes and investment properties follow the standard tables.

The Part Investors Skip: Qualifying the New Purchase

The line gets you the cash. It does not get you the loan. That second test comes down to one question: is the new purchase underwritten on your income or on the property’s?

On a DTI-based loan, the line payment counts as a liability. Debt-to-income, as Cornell’s Legal Information Institute explains it, compares your monthly debt payments to your gross monthly income. Add the line payment and the old home’s mortgage, and a borrower with solid income can still stall out. Lendmire’s piece Can You Buy a New Home Before Selling With a Conventional Loan? covers that route.

A DSCR loan works differently. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The line payment sits outside the coverage ratio. For the full picture, see the complete DSCR loans guide.

Credit, assets, reserves, and the appraisal are still reviewed. Here is what the network’s DSCR programs typically look like:

• Purchase leverage. Most files land at 75% to 80% LTV on a purchase, which means 20% to 25% down. Select programs reach 85% LTV with roughly a 700-plus score.
• Coverage. 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. A 620 floor exists in parts of the network. Most programs want around 660, and 700-plus unlocks the strongest tiers.
• Reserves. Commonly around 6 months of the full monthly obligation, though this varies by lender, leverage, loan size, and transaction type.
• Loan size. Loans run up to $3,000,000 on standard programs (smaller balances available through select lenders).

Two points trip people up. DSCR loans always require a down payment, so the line funds that, not the whole price. And clearing 1.00 is not positive cash flow. DSCR compares rent to the monthly obligation only. Repairs, vacancy, management, utilities, and capex sit outside it, and so does your line payment.

Policy on borrowed down-payment funds varies by lender. Ask before you draw, not after.

Run the Numbers: One Full Cycle

Picture an investor who owns a primary residence with solid equity and a credit profile above 720. A rental property is under contract at 75% LTV on a purchase. Rent on the new property is modeled to clear about 1.2x. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

The stages run like this.

• Stage one. The line is open and drawn. The investor carries the old mortgage and the line payment while the house is on the market.
• Stage two. The rental closes. Now three obligations stack: the old mortgage, the line payment, and the rental’s own payment. The rental’s rent covers its own payment at 1.2x, but the other two come from the investor’s pocket.
• Stage three. The old home sells. The old mortgage and the line are both paid off at the sale closing. Only the rental’s payment remains, and the rent covers it.

Now stress it. Run a three-month sale delay, then six, then nine. Each added month is another month of the first two obligations with no sale proceeds. Three months is a nuisance. Nine is a reserves problem. The DSCR ratio looks the same in all three cases, which is exactly why it misleads.

This is also why the 75% draw at closing matters. You cannot count on a large undrawn cushion to absorb a slow sale. Hold liquid reserves outside the line.

Where the General Rule Breaks

Here are the edge cases that change the answer.

The home is already listed. The line is often unavailable, and in five states it is ineligible by program rule. Fall back to a different structure: a bridge loan, a cash-out on the old home, or waiting out the lookback period.

The old home becomes a rental. Check the line’s terms first. The CFPB’s HELOC booklet says renting your home out may be prohibited under the terms of your line, and that a sale generally requires paying the line off. If you keep the home instead of selling, the line is not repaid at sale. The home can later move into a DSCR cash-out refinance on its rent. That tops out around 75% LTV on a standard rental, with about 6 months of seasoning as the common expectation.

The property is deeded to an LLC. The network’s equity lines cannot be written on a property titled in an LLC, corporation, partnership, or irrevocable, blind, or land trust. A property already in an LLC needs a vesting change or a DSCR cash-out instead. This is the sharpest structural difference between the two products. Where DSCR loans to LLC-titled borrowers are used, they remain subject to lender program eligibility.

You want a line on a rental you own. Investment lines exist in the network, but they are tight: 70% CLTV, a 700 credit floor, and a $500,000 maximum line, on the 5-year draw structure. Some lenders in the wider market advertise higher leverage on investment-property lines, according to BiggerPockets. That is a market-wide observation. The network’s investment ceiling is 70% CLTV. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

You were counting on a family member’s line. A line has to be yours. Another person’s equity line generally cannot serve as your funds.

The property type is off the list. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible on the equity lines. Condos, including non-warrantable ones, are eligible. On the DSCR side, manufactured homes (single- and double-wide), log homes, and barndominiums are not offered.

You have a history. A bankruptcy needs 4 years of seasoning. Foreclosure-family history splits by program and property use, so a file with one gets matched, not assumed.

HELOC, Bridge Loan, or Something Else?

A bridge loan is a short-term loan on the current home, built for this exact gap. Morgan Stanley says bridge loans tend to cost more than a typical mortgage and carry fees of 1.5% to 3% of the loan amount. Those are market figures, not network figures.

A bridge loan is not automatically worse. It is built for the listed-home case where the line is off the table. The line is usually cheaper and more flexible, but approval odds and fees differ by file. This is a toss-up on some files, and the broker’s job is to price both against the actual scenario.

Key Terms Defined

HELOC: An open-end line of credit that lets you borrow repeatedly against home equity. The CFPB describes it that way, with a draw period followed by a repayment period.

CLTV: Combined loan-to-value, which adds the first mortgage and the new line together and divides by the home’s value.

DTI: Debt-to-income ratio, your monthly debt payments divided by gross monthly income.

Draw period: The stretch when you can borrow against the line, usually interest-only on these programs.

Repayment period: The stretch after the draw ends, when the balance amortizes.

DSCR: Debt service coverage ratio, the rent divided by the property’s own monthly obligation: principal, interest, taxes, insurance, and any HOA dues.

Questions to Ask Before You Apply

A broker earns its keep on these. Bring them to any lender conversation.

• Is the line eligible if I list within the lookback period in my state?
• Which draw structure applies, and what does it do to my payment after the draw ends?
• Will the new purchase lender accept line proceeds as the down payment, and what documents does it need?
• Does the purchase test my DTI or the property’s rent?
• Does the line allow me to rent out the home if the sale stalls?
