Banks That Offer a HELOC to Tap Condo Equity for the Down Payment Before Selling

The Quick Read: Banks and credit unions that write a home equity line on a condo will generally let you borrow against it for the next down payment, but only if you open the line before the condo is listed, the building passes review, and the lender financing your next property accepts borrowed funds. No single list of banks holds up, because each lender sets its own rules on condos, investment use, and listings. The better question is what these lenders look for and how to find the one that fits your file.

• Open the line before you list the condo. Many lenders decline once a listing is live.
• The condo is underwritten as a building, not just a unit, so association finances and insurance matter.
• The lender buying your next property decides whether borrowed funds count as your down payment.
• Passing the rental coverage test on the new property does not mean the deal cash flows once the line payment starts.
• Within Lendmire’s network, an investment-property line tops out at 70% combined loan-to-value (CLTV), subject to lender guidelines.

Key Terms Defined

Home equity line of credit (HELOC): A revolving credit line secured by your property. You borrow against it, repay it, and borrow again during a set window.

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

Repayment period: The stretch after the draw period ends, when you pay down principal and interest until the balance is zero.

CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the property’s value. It caps how much you can borrow.

Warrantable condo: A building that meets the standards for conventional agency financing. A non-warrantable condo misses one or more of them, often over reserves, litigation, or investor concentration.

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

Bridge loan: A short-term loan that supplies a lump sum for a down payment while you wait for another property to sell.

Which Banks Offer This? It Depends on Four Things

Lenders that write condo equity lines differ on four points: how they treat condos, whether they allow investment use, how they handle a listed property, and what they want in the file. That is why a fixed list of banks goes stale. Lendmire is a mortgage broker, not a lender, so it does not rank institutions. Instead, it places lines through select wholesale lenders and matches the file to the program.

Here is how the lender channels differ in general.

Retail lenders sometimes decline the stated purpose outright. A BiggerPockets thread describes one bank saying its rules barred using a line for an investment purchase. That is one anecdote, but it shows why the purpose you state matters before you apply.

Availability also narrows on the Lendmire side. Its DSCR programs span 41 markets, including Washington, D.C. The home equity line described here is offered only in the 16 states where Lendmire provides full-service mortgage lending.

How the Strategy Works, Step by Step

The sequence matters more than the product. Each step has to happen in order, because the condo’s sale is what finally retires the line.

1. Open the line while the condo is unlisted. The application, valuation, and condo review all happen before a listing exists.

2. The lender underwrites the condo as a project. Expect questions about association finances, insurance, owner-occupancy levels, and litigation.

3. Draw the money into your own account. The cash then sits there as your down payment funds. Within Lendmire’s network, at least 75% of the line is drawn at closing, so size the line to the need.

4. Document the source for the purchase lender. The purchase lender, not the line’s lender, decides whether borrowed funds are acceptable. A BiggerPockets thread describes one lender wanting about two months of funds sitting in the account. That is anecdotal and varies by lender.

5. Close on the next property and carry three debts. You pay the first mortgage on the condo, the line, and the new loan until the condo sells.

6. Sell the condo and pay off the line. Sale proceeds retire the balance.

Leverage and reserves are separate questions. Some programs accept borrowed funds for the down payment but exclude them from reserves, or cap the borrowed share.

What a Wholesale Network Line Looks Like

The best program for your situation depends on occupancy, credit profile, and how much equity the condo holds. Across Lendmire’s wholesale network, the ceiling is tied to how the condo is used.

Those 90% ceilings exist only at a 720 credit profile or better. Lower scores step down through tiers, and the larger primary-residence lines carry tighter CLTV caps. Lines above $500,000 are limited to primary residences and require a full appraisal.

A few other mechanics shape the plan:

• Structure: Primary residences and second homes can choose a 3-year interest-only draw with a 17-year repayment, or a 5-year draw with a 25-year repayment. Investment lines use the 5-year draw and 25-year repayment only.
• Payments: Pricing floats through both the draw and repayment periods and never converts to a fixed figure.
• Debt-to-income: The maximum is 50%, and the lender reviews your file on the interest-only payment calculated at the maximum draw.
• Valuation: Lines at or below $500,000 ordinarily use automated valuation. A higher CLTV may require a secondary valuation, and you can request a full appraisal in any case.
• Exposure: A borrower is limited to three lines and cannot own more than 15 financed properties.

Every figure is subject to lender guidelines and full file review. Market-wide surveys report different equity cushions and ceilings, and those describe the broader market, not this network.

Does the Condo Itself Pass?

Condo lines are possible in many cases, but approval is more involved than for a detached house. CBS News notes that lenders look at your credit and equity, and also at the association’s financial stability, insurance coverage, owner-occupancy levels, and litigation status.

Here is what that means in practice. Low association reserves, a pending lawsuit, or a heavy share of investor-owned units can complicate approval. They do not automatically disqualify the condo. Within Lendmire’s network, condominiums are eligible even when non-warrantable. Condotels are not offered. Neither are co-ops, manufactured homes, log homes, or barndominiums.

Title matters too. The borrower must hold title as an individual or through a revocable living trust. A condo deeded to an LLC cannot take this line, so it needs a vesting change first, or a DSCR cash-out refinance instead.

Listing Day Is the Deadline

Within Lendmire’s network, a property that is listed for sale, or was listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington. Texas adds more rules for primary residences, including a lower combined cap.

If the condo is already listed, the usual workaround is to pull equity from a different property. One path is a DSCR cash-out refinance on a rental you already own. Lendmire’s piece Best Cash-Out Refinance Program to Tap Condo Equity for the Down Payment Before Selling covers that route in detail.

What Happens to the Line When the Condo Sells

A HELOC is an open-end line you can borrow against repeatedly during the draw period, according to the Consumer Financial Protection Bureau. The same page notes that borrowers who cannot keep up with payments could lose the home.

The payoff rule is what makes this work as a bridge. The agency’s HELOC booklet says that if you sell the home, you are generally required to pay the line off in full right away. The sale closes, the title company pays off the first mortgage and the line, and you keep what remains.

The risk sits on the other side. If the sale slips, the line stays open and the payments keep running. Plan for that before you draw.

The Carry Math: Passing Coverage Is Not Positive Cash Flow

Run the numbers on a modeled scenario. Say your condo is your primary residence, your credit profile is 720 or better, and your first mortgage sits well under half of the condo’s value. That leaves room under the network’s 90% CLTV ceiling, which applies to primary residences at 720 and above.

You use the line to cover the down payment on a rental. On a purchase, most DSCR files land at 75%-80% LTV, so you need 20%-25% down, plus closing costs. Select programs reach 85% LTV on a purchase with roughly a 700-plus score. Assume the rent covers the new property’s PITIA at about 1.15x. That clears 1.00x, which is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.

Now look at what the 1.15x leaves out. DSCR compares rent to PITIA only. The line payment sits outside the ratio, and so do repairs, vacancy, management, utilities, and capital expenses. A deal can clear the coverage test and still lose money each month after the line payment. A BiggerPockets thread makes the same point: cash flow has to cover both the mortgage and the line.

A fully borrowed down payment also means you are financing nearly the whole price. Lenders that buy the new loan still apply their own leverage caps, credit floors, and reserve rules. Reserves vary by lender, leverage, loan size, and transaction type, and commonly run around six months of PITIA. A larger down payment can lift coverage, but it never erases those rules. The strongest files clear both tests: enough equity and enough rental coverage.

Alternatives Worth Comparing

Several routes can fund a down payment before the condo sells, and the right one depends on timing. A home equity line costs less setup if you plan ahead, while a bridge loan suits a tight timeline. The comparison below shows where each option fits.

For the full picture of how rental-income loans work, see the complete DSCR loans guide. On a cash-out refinance, the network tops out around 75% LTV, with seasoning of about six months a common expectation. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

Who This Fits and Who It Doesn’t

The strategy fits an investor with strong equity, a credit profile at or above the tiers above, and a condo in a building that will sell within the draw window. It also helps if the next property has coverage to spare.

It fits poorly in four cases:

• The building has troubled finances or active litigation.
• The condo is already listed.
• The title sits in an LLC.
• The sale timeline is uncertain, and you cannot carry three debts.

Short-term rental purchases follow their own rules. They go to 75% LTV with a 640-plus score and about 12 months of hosting history. Short-term rental rules vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
