Buy Before You Sell: Using a HELOC for the Down Payment on Your Next Home

The Buyer’s Dilemma

You found the next home. You want to move on it now. But most of your money is locked up in the home you already own.

The right home doesn’t wait. And in most markets, contingent offers — offers tied to the sale of your current home — get pushed aside. Sellers pick the clean buyer who can close on time.

Selling first sounds like the safe play. In practice, it puts you on the street or in temporary housing while you shop. It also costs you leverage in the next negotiation.

Buying first sounds risky. How do you come up with the down payment when your equity is tied up in the current house?

There is a clean answer: pull the down payment out of your current home with a HELOC — before you sell it or move out. Then write a clean, non-contingent offer on the next home. Then decide what to do with the first one.

The Strategy in One Box

How the Strategy Works

There are two ways this plays out. The choice depends on whether you plan to sell the current home or keep it.

Both start the same way. You apply for a Lightning Equity HELOC against your current home. You draw the cash you need for the down payment on the next home. You close on the new home.

From there, the paths split.

Path 1 — Sell the current home

After you move into the new home, you list and sell the old one. At closing, the HELOC gets paid off out of the sale proceeds. You walk away with whatever is left. The HELOC was a short-term bridge.

Path 2 — Keep the current home as a rental

You move out, find a tenant, and keep the property as a rental. The HELOC stays on the property. You pay it back over time — typically from rental income or other cash flow.

Both paths are allowed under the Lightning Equity Hybrid HELOC. The product was built to handle both.

Path 1: You Plan to Sell Your Current Home

This is the classic bridge use case. You need cash now. You will get cash back when the old house sells. The HELOC fills the gap.

How it works

• Apply for the HELOC while your current home is still your primary residence.
• Draw the cash for the down payment on the next home.
• Close on the next home.
• List your old home for sale when you are ready.
• When the old home sells, the HELOC is paid off at closing out of sale proceeds. You net the difference.

What’s different when the home is listed for sale

Lightning Equity allows a HELOC on a property listed for sale, but with tighter limits than a non-listed property:

The smarter move: apply before listing

If you have not listed yet, you can usually apply for the HELOC at the better non-listed terms (up to $750,000, up to 85% CLTV on strong credit). The home is still your primary residence. The listing comes later.

“The order matters. Apply for the HELOC before the MLS listing goes live. You get a bigger line at better terms.”

Path 2: You Plan to Keep Your Current Home as a Rental

This is the portfolio play. You upgrade to a new home but turn the old one into a rental property. The HELOC stays. Rental income covers the payment.

How it works

• Apply for the HELOC while you still live in the current home — it is your primary residence on paper.
• Draw the cash for the down payment on the next home.
• Close on the next home and move in.
• List your old home for rent, sign a lease, and start collecting rent.
• Keep paying the HELOC over time. The rental cash flow typically covers it.

Why this works

The HELOC is approved on owner-occupied terms because that is what the property is at the time of application. Lightning Equity does not require ongoing occupancy verification after closing. You can convert to a rental later without renegotiating the HELOC.

What you get on owner-occupied terms

Compare that to applying after you move out. If the home is already a rental at application, you are looking at non-owner-occupied terms: max 70% CLTV, max $350,000 loan amount. The earlier you apply, the better the terms.

“Apply while the home is still your primary residence. You lock in the owner-occupied terms. What happens next is up to you.”

The Math: A Real Example

Let’s walk through both paths with the same starting numbers.

Starting position

HELOC available on the current home

At 80% CLTV on owner-occupied terms (applying before listing):

$600,000 × 80% = $480,000 maximum combined loan amount
$480,000 − $300,000 first mortgage = $180,000 HELOC available

That covers the $145,000 down payment with $35,000 left over for closing costs, moving expenses, or reserves.

Path 1 outcome (sell the current home)

• Use $145,000 of the HELOC for the down payment on the new home.
• Move into the new home.
• List the current home for sale. Assume it sells for $600,000.
• At closing on the sale: first mortgage payoff ($300,000) + HELOC payoff ($145,000) + closing costs (~$40,000 with agent commission) = $485,000.
• Net cash to seller: ~$115,000.

That net cash funds reserves, future repairs on the new home, or a one-time lump sum redraw on the HELOC for the next opportunity.

Path 2 outcome (keep as a rental)

• Use $145,000 of the HELOC for the down payment on the new home.
• Move into the new home.
• Rent the current home for, say, $3,200/month.
• First mortgage (P&I + tax + insurance): ~$2,100/month. HELOC interest-only payment on $145,000: ~$1,200/month (rate varies). Total monthly: ~$3,300/month.
• Cash flow is roughly break-even. The property pays for itself. You keep the appreciation, the principal paydown, and the tax benefits.

Over time, you can pay down the HELOC, refinance into a fixed second mortgage, or just let rent service the debt while the property appreciates.

Why Lightning Equity Uniquely Allows Both Paths

Most lenders will not give you a HELOC on a property that is listed for sale. The risk of payoff timing makes them nervous. Most lenders will also not give you owner-occupied terms if they suspect you are about to move out.

Lightning Equity is built for both scenarios.

“The product was built to handle the exact transition this strategy creates. Most lenders treat that transition as a problem. This one treats it as a feature.”

What to Watch For

Apply before you list

If you can, apply for the HELOC before the listing goes live on MLS. You get higher loan amounts and higher CLTV. Once the property hits MLS, the $400,000 cap and 80% CLTV apply.

Stay on top of your DTI

During the transition you may carry two mortgages plus the HELOC. Lenders on the next-home purchase will look at all three when they calculate debt-to-income. Run your numbers before you commit.

Have a plan for the old home

Path 1 needs a sale. Path 2 needs a tenant. Either way, the HELOC payment starts as soon as you draw. Map out the timeline before you submit the application.

Use of proceeds is flexible

The HELOC funds can be used for the down payment, closing costs, moving expenses, repairs on the new home, or kept as reserves. No documentation is required on how you spend the money once the HELOC is funded.

Lender-of-record for the new home matters

Your purchase lender will count the HELOC payment in your DTI. Some lenders are more accommodating than others when an applicant has a HELOC plus two mortgages in the picture. Pick a lender who has seen this strategy before.

Ready to Run the Numbers?

Apply takes about two minutes. Soft credit pull only — no SSN required to see your offer. You’ll see your maximum HELOC, your estimated rate, and your monthly payment.

From there, you can decide whether the strategy works for your situation.
