Using a HELOC to Buy Your Next Colorado Home: How It Works and When It Beats a Bridge Loan

By Prerna Kapoor, CLHMS | REAL Brokerage | July 7, 2026

A couple I worked with in Lone Tree last year found their next home before their current one had even hit the market. They loved it, the sellers wanted a quick close, and waiting for their own house to sell first wasn’t realistic. Instead of scrambling for a specialty bridge loan, their lender opened a HELOC against the equity in their current home, and that gave them the down payment they needed to move on the new house without a rushed sale. It’s one of the more useful tools I bring up with clients who are buying and selling at the same time, and it’s also one of the more misunderstood.

How a HELOC Actually Works

A home equity line of credit lets you borrow against the equity in a home you already own, typically up to somewhere around 80% of the combined value between your mortgage balance and the new line. Unlike a home equity loan, which hands you a lump sum upfront, a HELOC works more like a credit card. You get approved for a credit limit, and you draw against it as you need it during what’s called the draw period, which usually runs five to ten years.

During the draw period, most lenders only require interest-only payments on whatever you’ve actually borrowed. Once the draw period ends, you move into the repayment period, often another ten to twenty years, where you start paying down both principal and interest. That transition is worth planning for, since the payment jump from interest-only to fully amortizing can be significant if you’re not expecting it. HELOC rates are also usually variable, tied to the prime rate, so your payment on any outstanding balance can move over time.

Using Your Current Equity to Buy Before You Sell

If you already have equity built up and your current home isn’t going anywhere in the next few months, a HELOC can be a genuinely efficient way to access cash for a down payment on your next place. You open the line, draw what you need for the new purchase, and pay it down once your current home sells and the proceeds come through. The appeal is using equity you already have instead of taking on a new specialty loan product built just for this one transaction, like a bridge loan.

The tradeoff is that you’re carrying your existing mortgage, a new mortgage on the next home, and the HELOC payment all at once until the sale closes. That’s manageable for a lot of buyers if the gap is short, but it’s worth running the actual numbers with your lender before you commit to a timeline, especially if there’s any chance your current home takes longer to sell than you’re planning for.

The Tax Deduction Detail Most People Miss

Under current IRS rules, HELOC interest is only deductible when the funds are used to buy, build, or substantially improve the home that secures the loan. If you take out a HELOC against your current house and use that money as the down payment on a different home, the interest generally doesn’t qualify for the deduction, since the funds weren’t used on the property securing the debt. I’m not a tax advisor, and this is exactly the kind of detail worth confirming with your CPA before you file, but I bring it up because a lot of buyers assume all HELOC interest is automatically deductible, and that isn’t true.

HELOC or Bridge Loan: Which Fits Your Situation

A bridge loan is built specifically for this transaction. It’s typically a shorter-term loan, often six to twelve months, sized around the equity in your current home, with the expectation that it gets paid off the moment your old house sells. Bridge loans usually carry higher rates and more fees than a HELOC, but they don’t depend on you already having an open line of credit in place.

A HELOC tends to make more sense if you already have one set up, or if you have time to open one before you need the funds, since underwriting a new HELOC usually takes a few weeks. A bridge loan tends to make more sense if your timeline is tight, you don’t already have equity access set up, or your current lender’s HELOC terms aren’t competitive. If you’re weighing other ways to put existing assets to work for a purchase, I’ve also written about how asset depletion loans let some buyers qualify using investment accounts instead of W-2 income. My Colorado buyer financing playbook covers the fuller range of ways to structure a purchase like this. Either way, I’d rather walk through both options with you and your lender before you’re under contract on the next house, not after.

Quick answers

Do I need to sell my current home before opening a HELOC? No. A HELOC is based on the equity you already have, so it can typically be opened while you still own and live in the home.

Will my lender let me keep a HELOC open once my home is under contract to sell? It depends on the lender. Some restrict new draws once a home is under contract, so this is worth confirming early, not after you’ve written an offer on the next house.

Is a HELOC cheaper than a bridge loan? Usually, yes, in terms of rate and fees, but it depends on whether you already have one in place and how much equity you actually have to draw against.

If you’re weighing a HELOC against a bridge loan for your next move, I’m happy to walk through both with you and connect you with lenders who handle this regularly. No pressure, just the real tradeoffs.
