Buying your next home in Willowbrook before your current one sells can feel like a high-wire act. You want to make a strong offer without a home sale contingency, but you also need funds for the down payment and closing costs. The good news is you have tools to bridge the gap. In this guide, you’ll learn the key differences between a bridge loan and a HELOC, how lenders underwrite each, when each option fits best, and what to expect in DuPage County. Let’s dive in.
Bridge loans: what to know
A bridge loan is a short-term loan designed to give you cash for a down payment or closing costs when you buy before you sell. It is usually secured by your current home and sometimes also by your new purchase. Terms are typically 6 to 12 months.
Many bridge loans have interest-only payments during the term, with a balloon payoff when your current home sells. Costs often include an origination fee, appraisal, lender legal and closing fees, and the interest rate is usually higher than a standard mortgage. Lenders review your credit, income, combined loan-to-value limits, and may require a listing agreement or a sales contract for your current home.
The main risk is timing. If your current home does not sell within the term, you are still responsible for the bridge loan plus your new mortgage. Extensions can be possible, but they add cost.
HELOCs: what to know
A HELOC, or home equity line of credit, is a revolving credit line secured by your current home. You draw what you need during a draw period, commonly 5 to 10 years, and you often pay interest only on what you use.
HELOC interest is commonly variable, tied to a benchmark rate, sometimes with options to fix portions of the balance. Upfront costs are usually lower than for bridge loans, and underwriting focuses on your credit, debt-to-income, and total equity in the home. The lender will look at the combined loan-to-value, which includes your first mortgage plus the HELOC.
Keep in mind that the new mortgage lender may treat the HELOC as outstanding debt, even if the balance is low or zero, which can affect how much you qualify to borrow. Timing matters too. Some HELOCs take longer to set up and may require the loan to be recorded before you can draw.
Key differences that matter
Speed and competitiveness
Bridge loans are built for buy-before-sell situations and can often close quickly. This can help you write a cleaner, non-contingent offer in a competitive Willowbrook market. HELOCs are flexible and often cheaper, but setup can take longer and may not align with a fast purchase timeline.
Cost structure and payments
Bridge loans tend to carry higher interest rates and fees, but they are short term and often interest only. HELOCs usually have lower upfront costs and rates, but they are variable. A rising benchmark rate can increase your payment during the draw period.
Underwriting and CLTV limits
Both options depend on total equity. Lenders cap the combined loan-to-value across your first mortgage and any new financing. Your new mortgage lender will verify your funds and may count the bridge or the HELOC in your qualifying ratios. Last-minute HELOC draws must be documented to avoid delays.
Risk if your home sells slowly
With a bridge loan, a slow sale can push you toward an extension or carrying two properties longer than planned. With a HELOC, rate changes can raise monthly costs, and keeping the line open at purchase can reduce borrowing capacity for the new mortgage.
When a bridge loan fits best
- You need to make a non-contingent offer and close fast.
- You want a single short-term solution that is designed for buy-before-sell.
- You prefer predictable short-term payments and plan to sell quickly.
When a HELOC fits best
- You have time to set up the line and want lower upfront costs.
- You prefer flexibility to draw only what you need and reuse funds.
- You plan renovations after moving and want ongoing access to credit.
Local factors in DuPage County
Market timing and seasonality
Buyer and seller activity in Willowbrook and nearby suburbs often increases in spring and summer. In tighter inventory periods, sellers may favor quick closings without sale contingencies. Build your plan around realistic market timelines for listing, showing, and closing.
Property taxes and closing logistics
Property taxes and assessments are handled at the county level. As you plan carrying costs, account for tax proration at closing and any exemptions or appeals on your current home and the home you are buying. Verify transfer taxes, recording fees, and any municipal requirements early to avoid surprises.
Inspections, disclosures, and other checks
Older suburban homes may call for lead-based paint disclosures or a radon test. Lenders for bridge loans or HELOCs may require clear title and certain repairs before closing. Flood zones and school district boundaries can influence marketability and future sale prospects, which matters if you need your current home to sell promptly.
Timeline example: buy before you sell
- Week 1 to 2: Get pre-approved and discuss a bridge loan versus a HELOC with a lender. Align on combined loan-to-value limits and document how funds will be sourced for your down payment.
- Week 2 to 4: Prepare your Willowbrook home for market. Your agent provides a conservative pricing and net proceeds estimate plus a timeline.
- Week 3 to 6: Shop and write offers. If using a bridge loan, target a quick close. If using a HELOC, confirm the line is open and draw-ready before you write.
- Week 6 to 8: Close on the new home. Keep detailed proof of funds for any draws. Coordinate possession timing and any rent-back agreements.
- Week 8 to 16: List and sell your current home. Use sale proceeds to pay off the bridge loan or pay down the HELOC.
Your exact timing depends on market conditions, lender processing, and your home’s readiness. Build in buffers for underwriting, appraisal, and closing coordination.
Cost and risk checklist to compare
Use real quotes from lenders and run side-by-side scenarios.
- Upfront fees: origination, appraisal, legal and closing costs for each option.
- Interest cost: estimate total interest for 1, 3, and 6 months based on expected timelines.
- Rate type: short-term but higher rate for bridge loans, variable rate for HELOCs.
- Extensions and prepayment: bridge loan extension fees, HELOC prepayment or inactivity fees.
- New mortgage impact: how each is treated for qualifying, rate, loan-to-value, and mortgage insurance.
- What-if risks: slower sale than planned for a bridge loan, rate increases for a HELOC, or carrying two properties longer than expected.
- Tax questions: confirm mortgage interest deductibility with a tax advisor based on how funds are used.
Step-by-step plan to prepare
- Get pre-approved and discuss both products with a lender who understands DuPage County norms.
- Ask your agent for a conservative proceeds estimate and sale timeline for your current Willowbrook home.
- Request detailed fee sheets plus best-, base-, and worst-case scenarios for 1, 3, and 6 months.
- Align purchase and sale dates early. Put seller possession, rent-backs, or contingency terms in writing.
- Confirm title, insurance, HOA dues, and payoff details for both properties before closing.
- Keep a clean paper trail for all funds, especially any last-minute HELOC draws.
- Talk to a tax professional about interest deductibility and any implications for your situation.
Common pitfalls to avoid
- Waiting too long to open a HELOC, then finding it is not draw-ready at offer time.
- Assuming a zero HELOC balance will not affect qualifying. Lenders may still count it.
- Underestimating market time for your current home. Plan for a slower-than-hoped sale.
- Forgetting extension fees on a bridge loan or payment changes on a variable-rate HELOC.
- Skipping documentation of funds, which can delay your purchase closing.
Choose with confidence
Both tools can work well for Willowbrook move-up buyers. A bridge loan can help you win in a fast, competitive situation. A HELOC can lower costs and add flexibility if your timeline allows. The best choice comes down to your equity, qualifying capacity, risk tolerance, and how quickly you need to close.

How fast can a bridge loan or a HELOC close in DuPage County?
- Bridge loans often close in days to a few weeks when documentation is ready, while HELOCs typically take longer due to underwriting and appraisal.
Is the interest on a bridge loan or HELOC tax deductible?
- It depends on how the funds are used and current tax law. Confirm deductibility with a qualified tax professional.
