You’ve found the right neighborhood. You know roughly what you want in your next home. The only thing standing between you and making an offer is a question your lender hasn’t fully answered yet:
How do you fund the down payment on your next home before your current one sells?
This is the central financial puzzle of every move-up transaction in Denver Metro. And the answer depends entirely on which financing tool fits your equity position, your timeline, and your risk tolerance.
I work with move-up buyers in Broomfield, Erie, Lafayette, Louisville, and across the Northwest suburbs every week. The families who move with confidence are the ones who understand their financing options before they fall in love with a home they’re not yet positioned to buy.
Here’s a clear, side-by-side breakdown of the three main paths: bridge loans, HELOCs, and the traditional buy-then-sell sequence — so you can walk into your lender conversation already knowing the right questions to ask.
What Problem Are We Actually Solving?
The core challenge is simple. Your down payment for the next home is probably sitting in your current home as equity. You can’t access that equity until you sell — but you don’t want to sell until you’ve secured the next home.
This creates a liquidity gap. The three tools below each solve this gap in a different way, at different cost and risk levels.
Understanding the tradeoffs isn’t just financial housekeeping. It directly affects which offers you can make, how competitive you can be in a multiple-offer situation, and whether you can negotiate from a position of strength or desperation.
Option 1: Bridge Loan
A bridge loan is a short-term loan secured against the equity in your current home. It “bridges” the gap between the purchase of your next home and the sale of your current one.
How it works: Your lender advances you a loan — typically up to 80% of your current home’s value minus your existing mortgage balance. You use that cash as the down payment on your new home. When your current home sells, you pay off the bridge loan in full.
The cost: Bridge loans carry higher interest rates than conventional mortgages — often 1.5 to 3 percentage points above prime — plus origination fees. Because these loans are designed to be repaid within 6–12 months, the total cost is manageable for most buyers, but it’s real money. A $150,000 bridge loan at 8.5% for six months costs roughly $6,375 in interest before fees.
When it makes sense: Bridge loans work well when you have solid equity in your current home, high confidence it will sell quickly, and you need speed. You don’t need a pre-existing credit line — you apply for the bridge loan fresh when you need it. In Denver’s Northwest suburbs, where well-priced homes in Broomfield and Superior regularly go under contract within two weeks of listing, bridge loans are a tool that active move-up buyers should understand.
The risk: If your current home takes longer to sell than expected, you’re carrying two mortgage payments plus bridge loan interest. That’s a meaningful monthly burn. Make sure your lender models out a worst-case scenario — what does it cost you if your home takes 90 days instead of 30?
Option 2: HELOC (Home Equity Line of Credit)
A HELOC is a revolving credit line secured against your home’s equity. Think of it like a credit card backed by your house — you draw what you need, when you need it, and only pay interest on what you’ve actually borrowed.
How it works: You open a HELOC before listing your current home. Once approved, you have access to a credit line — typically up to 85–90% of your home’s appraised value minus your mortgage balance. When you’re ready to buy the next home, you draw from the line to fund your down payment. After your current home sells, you repay the balance.
The cost: HELOCs carry variable interest rates tied to the prime rate. In the current environment, HELOC rates are lower than bridge loan rates for most borrowers with strong credit. There’s typically no origination fee or closing cost the way there is with a bridge loan, making a HELOC the lower-cost option if you can open one in time.
The critical timing issue: Most lenders will freeze or close your HELOC the moment your property goes on the market. This means you must open the HELOC before you list your home for sale — ideally 30–60 days in advance. Many move-up buyers miss this window entirely because they don’t know the rule until it’s too late.
When it makes sense: A HELOC is ideal if you already have one open with available credit, or if you’re planning your move-up 60+ days in advance and can get one established first. It’s the most cost-efficient bridge tool available — but it requires early action and planning.
Option 3: Buy-Then-Sell (With Liquid Reserves or Financing)
The buy-then-sell sequence means purchasing your next home outright before listing your current one. This gives your family the cleanest possible experience — move in, get settled, then list and sell without the pressure of a simultaneous transaction.
How it works: You need enough capital to close on the new home before your existing home sells. That can come from: liquid savings or investment accounts, a bridge loan (see above), a HELOC draw (see above), retirement account loans (check tax implications with your CPA), or gift funds from family.
The cost: The direct cost depends on which funding source you use. If you’re drawing from liquid savings, the cost is the opportunity cost of having capital tied up. If you’re using a bridge loan or HELOC, those costs apply as above.
The real advantage: You become a non-contingent buyer. In competitive move-up markets across Louisville, Lafayette, and parts of Arvada, removing the home sale contingency from your offer can be the difference between winning and losing a multiple-offer situation. Sellers strongly prefer buyers who aren’t dependent on the sale of another property.
The risk: If your current home doesn’t sell quickly — or sells for less than projected — you’re carrying two full mortgage payments for an extended period. Know your exact monthly exposure before you commit to this path. And be honest about whether your current home is genuinely priced and positioned to move fast.

What I Tell My Clients Before They Talk to a Lender
The financing question always comes after the strategy question. Before you pick a tool, you need to know:
1. What is your current home actually worth — and how fast will it sell? This isn’t about what Zillow says. It’s about what comparably sized, comparably updated homes in your specific neighborhood have actually sold for in the last 90 days. I run this analysis for every client before we touch the financing conversation.
2. How much equity do you actually have? Call your mortgage servicer and get the current payoff amount. Then compare that to a realistic selling price (not an optimistic one). The difference is your accessible equity — and that number drives which tools are available to you.
3. What’s your family’s real monthly capacity if things go sideways? If you end up carrying two housing payments for 60 days, what does that cost you — and can you absorb it without stress? The answer shapes which risk level is appropriate.
These three questions tell me which financing path makes the most sense before we’ve spoken to a single lender. They also make your lender conversation dramatically more productive because you walk in with real numbers instead of rough guesses.
Frequently Asked Questions
What is a bridge loan and how does it work for move-up buyers in Denver?
A bridge loan is a short-term loan secured against your current home’s equity that gives you the cash to buy your next home before your existing property sells. In Denver, bridge loans typically cover 6–12 months and carry higher interest rates than conventional mortgages. They’re best for buyers with strong equity positions and high confidence that their current home will sell quickly.
Can I use a HELOC to buy my next home before selling in Denver?
Yes, but timing is critical. A HELOC must be opened before you list your current home — most lenders will freeze or close the line once the property hits the market. If you have an existing HELOC with available credit, you can draw from it to fund your down payment on the next home, then repay it when your current home sells.
What does buy-then-sell mean for Denver move-up buyers?
Buy-then-sell means purchasing your next home first and then listing and selling your current property afterward. This eliminates the risk of being between homes but requires either sufficient liquid reserves, bridge financing, or a HELOC to cover the down payment gap. It works best when you have substantial equity and confidence in your current home’s saleability.
Is a bridge loan or HELOC better for Denver move-up buyers?
It depends on your situation. A HELOC is generally lower cost and more flexible if you can open it before listing. A bridge loan is faster to obtain and doesn’t require an existing credit line, but costs more. Most Denver move-up buyers benefit from speaking with a lender about both options to compare the real cost difference given their equity position and timeline.
How much equity do I need to use a bridge loan or HELOC in Denver?
Most lenders require at least 20% equity in your current home to qualify for a bridge loan, and many prefer 30–40%. HELOC requirements vary by lender but typically allow you to borrow up to 85–90% of your home’s value minus what you owe. Denver’s appreciation over the past several years means many homeowners have more equity than they realize.
Let’s Figure Out Which Path Makes Sense for You
The financing question is one of the most consequential parts of the move-up process — and it’s one of the most underplanned. Most families don’t think about it until they’re already in love with a home they’re not yet positioned to buy.
My approach is to solve this well in advance. I help my clients map out their equity position, model the real cost of each financing option, and connect them with Denver-area lenders who specialize in move-up transactions. By the time we’re writing offers, the financing question is already answered.
