Banks That Offer a HELOC to Purchase a Second Home Without Selling Your Current One

The Quick Read: Many lenders will let you open a home equity line on a property you keep and spend the cash as a down payment on another property. The line agreement and the purchase lender’s own rules decide whether your file works. The line is only a source of cash, and the new mortgage is a separate loan with its own approval.

• Across Lendmire’s wholesale network, a line on a primary residence or second home reaches up to 90% CLTV only at a 720-or-better credit profile. A line on an investment property tops out at 70% CLTV.
• Lines run from $25,000 to $750,000, so the size of the line should match the cash you actually need.
• A rental purchase usually moves to a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

Which Banks Offer a HELOC to Purchase a Second Home?

The honest answer is that it depends on the lender type, the property securing the line, and the wording of the line agreement. Lendmire is a mortgage broker, so it does not rank or recommend individual banks.

Lender categories lean in different directions. These are tendencies, not promises.

A broker shops several wholesale lenders and matches the property, credit profile, and leverage you need to the program that fits. The right program for you depends on your situation, not on a brand name. One limit applies: Lendmire’s HELOC placement covers 16 full-service states, which is narrower than its 41-market DSCR footprint (40 states plus Washington, D.C.).

Which Property Can Secure the Line, and How Much Can You Borrow?

Occupancy sets the ceiling. The line is secured by a property you already own, and the lender caps your combined loans against that property’s value. That measure is called combined loan-to-value, or CLTV: the first mortgage plus the new line, divided by the home’s value.

On a second home you already own, the ceiling steps down with credit. A 700 or 680 score tops out at 85% CLTV, 660 at 80%, and 640 at 75%. A primary-residence line above $500,000 is primary-only and caps at 75% CLTV. It requires 700 or better (720 on the longer-runway structure, the 5-year-draw structure described below) and a full appraisal.

Lines on primary and second homes come in two structures. One has a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other has a 5-year interest-only draw followed by a 25-year fully amortizing repayment. This article calls them the 3-year-draw structure and the 5-year-draw structure. Investment-property lines use the 5-year-draw structure only.

Pricing on both structures floats through the draw and the repayment period and never converts to fixed. Every figure here is subject to lender guidelines and full file review. This is not a commitment to lend.

How the Process Runs, Step by Step

The order matters more than any single number. Here is the sequence from first look at your equity to carrying all your payments.

1. Choose the collateral. Most owners pick their primary residence. An existing second home or rental can also secure a line, with the tighter limits above.

2. Run the CLTV math. The CFPB’s HELOC booklet describes the standard method. The lender takes a percentage of the appraised value and subtracts your mortgage balance. What is left is the room for a line.

3. Underwrite the line on you. Lines are personal-credit products. The maximum debt-to-income ratio (DTI, your monthly debts divided by your monthly income) is 50%. It is 45% for credit profiles from 600 to 679, and anything above 45% needs at least a 680 score. Qualifying uses the interest-only payment on the maximum draw, even if you plan to draw less.

4. Value the home. A line of $500,000 or less ordinarily uses an automated valuation instead of a traditional appraisal, though a higher CLTV may call for a second valuation. A line above $500,000 always needs a full appraisal. You can also ask for one on any line.

5. Close and draw. At least 75% of the line is drawn at closing, so you start paying on most of it right away. Plan the line around the cash you need, because a large undrawn line still costs you at closing and counts in your qualifying math.

6. Underwrite the purchase separately. The new loan has its own lender, its own approval, and its own rules on where your down payment came from. Ask about borrowed funds before you draw, not after.

7. Carry everything at once. Your first mortgage, the line, and the new loan are all due. Plan for that before you make an offer.

The CFPB defines a HELOC as an open-end line you can borrow against repeatedly during a draw period. A repayment period follows. The same page warns that you could lose your home if you cannot repay, because the home secures the line.

Run the Numbers: Three Payments, One Rental

Picture a homeowner whose first mortgage equals about 55% of the primary residence’s value. The credit profile is 720 or better. The 90% ceiling leaves meaningful room to borrow, and a lender may approve less. Say the owner sizes the line at a modest slice of the home’s value, which puts combined leverage near 70% CLTV. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

Now the owner buys a rental at 75% LTV on a purchase, which means 25% down. The line supplies that down payment. The rental carries 75% debt, and the owner’s home carries the borrowed equity on top. Across both properties, the owner has financed close to the full price. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

That stacking is the main risk of this strategy. A DSCR loan compares the rent to the property’s monthly principal, interest, taxes, insurance, and association dues (together called PITIA). Suppose the rental clears roughly 1.2x on that test. That ratio says nothing about the line’s payment, which belongs on the home’s side of the ledger. Judge the rental on its own, then look at the household with all three payments.

Clearing 1.00 on coverage is also not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the DSCR calculation. Budget for them separately.

A larger down payment lowers the new loan’s payment and can lift coverage. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files have enough equity and enough rental coverage.

Where the General Rule Breaks

Several situations change the answer. Know them before you apply.

LLC-held collateral. A line must be held by you personally or by an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. If a rental is already deeded to an LLC, it needs a vesting change, or a DSCR cash-out refinance is the better fit.

Use restrictions in the line agreement. Terms vary by plan. Some agreements limit renting out the home that secures the line, and some lenders discourage using proceeds elsewhere. Read the agreement before the home might become a rental.

Borrowed down payment. Whether the purchase lender treats line proceeds like seasoned savings is that lender’s call. It may also count the line payment as a debt or ask about reserves. A DSCR purchase is reviewed primarily on property-level rental income, but asset sourcing still follows the lender’s program.

An owner-occupied purchase. 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. If you plan to live in the new property, the DSCR route is off the table, and a line may be one of your few cash sources.

Selling the collateral home later. A line generally has to be paid off in full when you sell the home, so build the payoff into your exit plan. Lenders can also reduce a line if the home’s value falls substantially.

Property types. Neither line structure accepts manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, or agricultural zoning. Eligible collateral includes single-family homes, 2-4 units, PUDs, townhomes, and condos, including non-warrantable ones. On the purchase side, DSCR financing is not offered on manufactured homes (single- and double-wide), log homes, or barndominiums.

Borrower limits. You can hold up to three lines. Combined exposure caps at $2,000,000 on the 3-year-draw structure and $750,000 on the 5-year-draw structure. A borrower with more than 15 financed properties is not eligible. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by structure, so the history matters when you match the file to a program.

Why a Rental Purchase Usually Moves to a DSCR Loan

Lines depend on your personal income and credit and get harder to qualify for as you add properties. A DSCR loan looks at the rental property instead. The two products pair well: the line supplies the down payment, and the DSCR loan finances the property. The complete DSCR loans guide walks through the full mechanics.

Typical ranges across select lenders in the network look like this, always subject to guidelines:

• Purchase leverage: most files land at 75% to 80% LTV on an investment purchase, which is 20% to 25% down. Higher leverage is possible only on select programs and depends on credit strength.
• Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
• Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700 or higher unlocks the strongest leverage tiers.
• Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000 the network generally holds to 30-year fixed structures.
• Reserves: commonly around 6 months of PITIA. They vary by lender, leverage, loan size, and transaction type.

The line is usually a short-term bridge. A common exit is a DSCR cash-out refinance once the rental has seasoned. About 6 months is the common expectation, and cash-out tops out around 75% LTV on most of the network. Lendmire’s piece Best Cash-Out Refinance Program to Purchase a Second Home Without Selling Your Current One covers that route, which replaces your first mortgage instead of adding a second lien.

Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.

What to Ask Before You Apply

Take this list to any lender or broker. Each answer closes a gap before you draw.

• Does the line agreement allow proceeds to fund another property?
• Does it restrict renting out the collateral home?
• Will the purchase lender accept line proceeds as a down payment, and what reserves does it want?
• Does the purchase lender count the line payment as a debt?
• What is the CLTV ceiling for my occupancy and credit profile?
• How much of the line must I draw at closing?
• What happens to the line if I sell the collateral home or its value drops?
• What is my plan to pay the line down?

Key Terms Defined

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

Draw period: the stretch when you can borrow from the line, paying only interest on this network’s lines.

Repayment period: the stretch after the draw period when you pay the balance down in full.

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

DSCR (debt service coverage ratio): a rental’s monthly rent divided by its monthly PITIA.

PITIA: principal, interest, taxes, insurance, and association dues on a property.

Lien position: whether a loan is paid first or second if the property is sold or foreclosed.
