Top HELOC Providers to Buy Another Home Before Selling the First

The Quick Read: A home equity line of credit (HELOC) lets you borrow against a home you already own and use the cash as a down payment on the next one. Which lenders write that line depends on your occupancy, credit, equity, and state, so the right program is the one that fits your file. Lendmire is a mortgage broker, not a lender, and it matches files to wholesale lenders in its network.

• Open the line before you list the old home. Several states bar lines on homes that are listed or were recently listed.
• On an investment property, network lines top out at 70% combined loan-to-value (CLTV). On a primary residence, 90% exists only at 720 or better credit.
• The line is a personal-credit loan, so your debt-to-income ratio (DTI) matters even when the purchase loan is a DSCR loan.
• A HELOC is variable and secured by the home you may still be living in.

Key Terms Defined

CLTV (combined loan-to-value): every loan recorded against a property, including the new line, divided by the property’s value.

Draw period: the stretch when you can borrow from the line, usually paying interest only.

Repayment period: the stretch after the draw ends, when you repay principal and interest and can no longer borrow.

DTI (debt-to-income): your monthly debt payments divided by your monthly income.

DSCR (debt service coverage ratio): monthly rent divided by the property’s full monthly payment (principal, interest, taxes, insurance, and any HOA dues). That payment is called PITIA.

Source of funds: the paper trail showing where your down payment came from.

What Does “Top Provider” Mean for This Strategy?

The best HELOC provider is the one whose rules match your property, credit, equity, and state. No single lender is best for every borrower.

That is why this article does not rank companies. Lendmire works with a network of wholesale HELOC lenders, and each one sets its own limits on occupancy, leverage, property type, and listing status. A broker’s job is to match your file to a program that fits. A lender that suits a high-credit owner of a primary home may not write a line on a rental at all.

The sections below show how these programs operate. They also show what to ask any provider before you apply.

How Does Buying Before Selling Work, Step by Step?

You open a line on a property you own, draw cash, buy the next property, and pay the line off when the old home sells or is refinanced. Order matters more than any other detail, because lenders restrict lines on homes already for sale.

1. Choose the collateral. The usual choice is your primary residence. A line on a rental you already own is possible, but Bankrate notes that investment-property lines are less common and carry stricter criteria.

2. Run the equity math. Available line equals the home’s value times the lender’s maximum CLTV, minus every existing lien. Lenders measure against the full approved line, not what you plan to use.

3. Apply before you list or go under contract. Darrow Wealth Management advises securing the equity line on your current home first. It names the down payment and staying within an acceptable DTI as the two main challenges.

4. Close the line and draw. On the network’s programs, at least 75% of the line is drawn at closing. You start paying interest on that cash right away, so plan the purchase timing around it.

5. Buy the next property. The purchase lender sees the new line as debt and asks where your down payment came from. Bankrate points out that not every lender allows home-equity funds as a down payment when you also take a mortgage on the new property.

6. Pay the line off. When the old home sells, the proceeds retire the line. If you keep the old home as a rental, you refinance or pay it down another way.

What Do Network Lenders Look For?

Leverage depends on the occupancy of the home securing the line. Across the wholesale lenders Lendmire places HELOC files with, the ceilings differ sharply by occupancy.

Lower credit tiers step the ceiling down. On a primary residence, 700 or better supports 85% CLTV up to $500,000, and a 640 score supports 80%. A line above $500,000 is for primary residences only. It requires 700 or better credit (720 on the 5-year draw, 25-year repayment structure) and a cap of 75% CLTV.

Two draw structures exist on primary residences and second homes. The first runs a 3-year interest-only draw, then a 17-year repayment. The second is a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Investment lines use the 5-year draw, 25-year repayment structure only. Pricing floats during both the draw and the repayment period and never converts to a fixed figure.

Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal. Every line above $500,000 requires a full appraisal, and you can request one at any size. Everything here is subject to lender guidelines and full file review.

How Is Your File Underwritten?

The line is underwritten to you, and the purchase loan is underwritten to the new property. Expect two separate reviews.

The line looks at credit, DTI, and equity. Maximum DTI is 50%, and 45% for credit profiles from 600 to 679. A ratio above 45% requires at least a 680 score. Lenders review your file on the interest-only payment calculated on the maximum draw, not the amount you plan to use. The line therefore looks smaller on paper than it does to the underwriter.

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. A DSCR purchase is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Across the network, most purchase files land at 75%-80% LTV (20%-25% down), and select programs reach 85% LTV at roughly a 700+ score. Market surveys report 15%-25% down on investment purchases, per Bankrate, which overlaps the network’s range.

Coverage of 1.00 is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, management, and capital expenses sit outside the ratio. The complete DSCR loans guide walks through the full calculation.

The HELOC does not replace the DSCR test. The strongest files clear both: enough equity for the line and enough rent for the new property. Expect the DSCR lender to ask for source-of-funds documentation. Reserves vary by lender, leverage, and loan size, and they commonly run around 6 months of PITIA.

Where Does the General Rule Break?

Most of the surprises come from eligibility rules that sit outside the numbers. These are the edge cases that change which providers can write your line.

Listed homes. A property listed for sale, or listed within the past 60 days, is ineligible in several states, including Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington. Open the line first, even if you are not sure you will sell soon.

LLC-titled rentals. The line must be held by you individually or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead. This is the sharpest structural difference from a DSCR loan.

Occupancy. Lenders underwrite the line at the occupancy you truthfully declare. If you plan to move out of the home securing the line, raise it with your broker up front, because the occupancy tier changes the ceiling.

Property types. Single-family, 2-4 units, PUDs, townhomes, and condos (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.

Exposure. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. An owner of more than 15 financed properties is not eligible.

Availability. HELOC placements run in 16 states, which is narrower than Lendmire’s 41-market DSCR footprint (40 states plus Washington, D.C.).

What Does a Worked Example Look Like?

Here is the shape of the math in percentages only. Say you own a primary residence and have a 700 credit score. The home carries a first mortgage equal to 55% of its value. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

At that credit tier, the ceiling is 85% CLTV on lines up to $500,000. Subtract the 55% already recorded, and the line could reach up to 30% of the home’s value, capped at $500,000. The calculator on this page can turn those percentages into dollars as an illustrative estimate.

Now stress the personal side. The lender tests your DTI using the interest-only payment on the full line, even if you draw only part of it. At least 75% of the line is drawn at closing in any case. If your DTI is already near 50%, a smaller line may fit better than the maximum. For borrowers with strong rent coverage on the new property, the DSCR purchase may still work at a leverage tier that suits the available down payment.

What Are the Risks?

The main risk is that your home secures the line. According to the CFPB, you could lose your home if you fall behind on a HELOC. The agency also notes that payments are often significantly higher once the draw period ends, and in some cases the whole balance can come due when repayment begins.

Variable pricing means your payment can move. While the old home is unsold, you may carry three obligations: the first mortgage, the line, and the new loan. A sale that stalls leaves you carrying all three, so build a plan for that case before you draw.

The CFPB’s HELOC brochure adds that some plans require an initial draw or a minimum draw per transaction. Read those terms before you sign.

What Are the Alternatives?

Two alternatives come up most often. A DSCR cash-out refinance borrows against a rental you already own and qualifies primarily on that property’s rent, which helps when personal DTI is the bottleneck. Cash-out tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation.

The other is a sale contingency in the purchase contract. It removes the carrying risk but may weaken your offer, depending on the seller and the market.

How Do You Vet a Provider Before You Apply?

Ask these questions of any provider, or have your broker ask them:

• Does the line allow the home to be listed, or recently listed, in your state?
• What is the maximum CLTV at your credit tier and occupancy?
• Can the line be used toward the down payment on an investment purchase?
• What share of the line must be drawn at closing?
• Is the draw period three or five years, and what follows it?
• Does the provider qualify you on the full line or on the amount you draw?
• Will it accept your vesting (individual or revocable trust)?
