A HELOC, home-equity loan or bridge loan can turn equity in your current house into cash for the next purchase before the current house sells. The products solve a liquidity problem, not automatically a mortgage-qualification problem. The new debt and both housing payments may still affect whether you qualify for the next mortgage.
The three tools work differently:
- a HELOC is a revolving line of credit secured by your current home;
- a home-equity loan generally gives you a lump sum secured by the current home; and
- a bridge loan is temporary financing designed to cover a short gap, including the period between buying a new dwelling and selling the current one.
The CFPB says HELOCs usually have adjustable rates, while home-equity loans commonly provide a lump sum and may have a fixed rate. Federal Regulation Z specifically uses a new-home purchase before sale of the current dwelling as an example of a temporary bridge loan. CFPB, HELOC vs. home-equity loan CFPB, Regulation Z §1026.43
What problem are you actually trying to solve: cash or qualification?
Move-up buyers often confuse equity with available cash. A home can contain substantial equity while the owner still lacks liquid funds for the next down payment.
Start with two separate tests:
Test 1 — Liquidity
How much cash do you need before the old house sells?
Include:
- due diligence fee and earnest money;
- down payment;
- inspections and appraisal;
- closing costs and prepaids;
- moving expenses; and
- reserves you do not want to spend.
Test 2 — Qualification
What payments will the lender count when underwriting the next mortgage?
Fannie Mae's current September 2026 guidance says that when a borrower's current principal residence is pending sale but will not transfer before the new purchase closes, the current and proposed PITIA generally must both be used for qualification. Fannie provides an exception when the lender has the executed sales contract for the current residence and confirmation that financing contingencies have cleared. Fannie Mae B3-6-06
A HELOC can solve the cash problem while making the qualification problem harder because it creates another debt obligation. Model both before opening or drawing the line.
How does a HELOC work for a move-up buyer?
A HELOC lets you borrow repeatedly up to an approved limit against your home equity during the draw period. It can be useful when you need access to cash but do not know the exact amount or timing in advance.
The CFPB's current guidance says:
- a HELOC is an open-end line secured by home equity;
- the borrower can generally draw repeatedly during the draw period;
- HELOCs usually have variable interest rates;
- payments can change with the outstanding balance and rate; and
- the lender can in some circumstances reduce or freeze additional borrowing, including after a significant decline in home value or a material deterioration in the borrower's financial condition. CFPB, What is a HELOC?
For a move-up purchase, the useful questions are:
- What credit limit will actually be available?
- What is the payment if I draw the amount needed for the next purchase?
- Is the rate variable, fixed-option or both?
- What fees apply to open, draw or close the line?
- What happens to the line when I sell the current house?
- Will the new HELOC payment affect qualification for the next mortgage?
Do not treat the unused credit limit as guaranteed cash forever. The CFPB's freeze/reduction warning is one reason to build a backup plan.
How is a home-equity loan different from a HELOC?
A home-equity loan normally provides one lump sum, while a HELOC is a reusable line during its draw period.
The CFPB says home-equity loans commonly have fixed rates while HELOCs usually have adjustable rates. Both are loans secured by the home, and if the borrower already has a first mortgage they are commonly second mortgages. CFPB, HELOC vs. home-equity loan
A lump-sum home-equity loan may fit better when the amount is known and payment predictability matters. A HELOC may fit better when the buyer wants flexibility to draw only what is needed.
Neither should be evaluated only by interest rate. Compare setup fees, minimum draws, required payments, payoff terms and what happens when the collateral property is sold.
What is a bridge loan?
A bridge loan is short-term financing used to span a temporary gap. In residential real estate, federal mortgage rules expressly give the example of financing a new dwelling when the consumer plans to sell the current dwelling within 12 months. CFPB, Regulation Z §1026.43
Regulation Z does not create a single national bridge-loan product. It recognizes temporary bridge financing as a category. Actual lenders can differ on:
- loan amount;
- collateral;
- interest rate;
- origination and other fees;
- whether payments are monthly or accrued;
- maximum term;
- required sale/listing status; and
- payoff mechanics after the current home sells.
For comparison, ask every bridge lender for a written total-dollar cost if the old house sells in 30, 60, 90 and 180 days.
Bridge loan vs. HELOC vs. home-equity loan
| Feature | HELOC | Home-equity loan | Bridge loan |
|---|---|---|---|
| Cash access | Repeated draws up to line limit | Lump sum | Typically lump sum/transaction-specific advance |
| Typical rate structure | Usually adjustable | Often fixed, though products vary | Product-specific |
| Intended time horizon | Can be multi-year | Can be multi-year | Short-term transition |
| Main move-up use | Flexible down-payment/closing liquidity | Known lump-sum need | Purpose-built timing gap |
| Main risk | Variable payment; secured by home; line can be reduced/frozen in some cases | Added fixed debt secured by home | Short maturity and carrying cost if sale is delayed |
| Qualification impact | New debt may be counted | New debt may be counted | Depends on lender/product and overall underwriting |
| Best comparison metric | Cost for amount actually drawn | Total cost and payment | Total dollar cost at multiple sale dates |
This table describes structure, not a recommendation. Product terms vary by lender.
How much does bridge financing cost if my sale is delayed?
Instead of comparing only rates, calculate time-to-sale cost.
A simple planning formula for interest-only illustration is:
Estimated interest = amount borrowed × annual rate × days outstanding ÷ 365
Then add lender/origination/closing fees.
Hypothetical example—not a market rate quote
Assume a borrower uses $100,000 of temporary financing at a hypothetical 10% annual simple rate, excluding compounding and fees.
| Time outstanding | Hypothetical interest |
|---|---|
| 30 days | about $822 |
| 60 days | about $1,644 |
| 90 days | about $2,466 |
| 180 days | about $4,932 |
The lesson is not that bridge loans cost 10%. The rate is deliberately hypothetical. The lesson is that sale timing is part of the price of temporary financing. A loan that looks inexpensive at 30 days can feel different at 180 days.
How much equity can I actually use?
Usable equity is not simply home value minus mortgage balance. A lender determines how much it is willing to lend based on its underwriting and collateral limits.
Use three separate numbers:
- Estimated market equity: home value minus debts secured by the home.
- Approved borrowing capacity: the actual HELOC/home-equity/bridge amount the lender is willing to provide.
- Net usable cash: approved amount minus fees, required payoffs and cash you intentionally keep in reserve.
Only the third number solves your down-payment problem.
What happens if I sell the old house after buying the new one?
The sale proceeds generally become the source for paying off loans secured by the old property, including the first mortgage and any equity borrowing that must be satisfied at sale.
The CFPB notes that repayment of a home-equity loan is often required when the home is sold. CFPB, Similar loans to a HELOC
Ask the lender and closing attorney for an estimated payoff/net-proceeds view before committing to the next home's down payment. A homeowner who says “I have $400,000 in equity” may have materially less in spendable sale proceeds after mortgages, equity loans, selling costs and adjustments are paid.
A four-scenario worksheet to run before house hunting
Ask the lender to show:
| Scenario | What to model |
|---|---|
| A. Buy first with cash | New mortgage while old home remains owned |
| B. Buy first + HELOC | New mortgage + old mortgage + expected HELOC payment |
| C. Buy first + bridge | New mortgage + bridge terms + old-home carrying costs |
| D. Sell/contract first | Qualification once old home is under executed sales contract and reaches required underwriting status |
For each scenario, record:
- cash needed before closing;
- monthly housing/debt payments during overlap;
- lender reserve requirements;
- estimated cost if sale takes 30/60/90/180 days; and
- the fallback if the old house does not sell on schedule.
That worksheet is more useful than choosing a financing product based on its name.
The key takeaway
HELOCs, home-equity loans and bridge loans can all help a homeowner buy before selling, but they solve different versions of the same problem. A HELOC provides flexible access, a home-equity loan provides a lump sum, and bridge financing is designed for a short transition. All add risk because the money is borrowed, not withdrawn from a savings account.
For a Cary or Morrisville move-up buyer, run the liquidity and qualification math separately. The right plan is the one that still works if the current home takes longer than expected to sell.
