Buy or Sell First? 5 Ways to Move Up in the South Denver Metro

Written for people who've outgrown their home in Littleton, Highlands Ranch, and the rest of the South Denver Metro.

"We need a bigger house. But before we can buy a bigger house, we have to sell this one." That's the loop almost every homeowner is stuck in when they call. And it leads straight to the question everyone asks next: do we buy first or sell first?

Here's the good news: buying first is possible for more homeowners than most people realize. You don't always need to carry two mortgages or have a pile of cash in the bank. Programs available today can unlock the equity in your current home so you can buy the next one first, move once, and sell the old one after you're settled. This guide walks through all five ways to move up in the South Denver Metro, starting with the one most homeowners prefer, and shows what each costs using a real-numbers example of a family selling in Littleton and buying in Highlands Ranch.

Jacob Stark is a South Denver Metro REALTOR® who also renovates and invests in homes, so he looks at both the process and the numbers. And if selling first turns out to be the better fit for you, this guide covers that too.

Could You Buy Your Next Home First?

For most South Denver Metro homeowners, buying first is the better experience. You move once. You never have to keep the house showing-ready with work, kids, and life going on. And your offer on the next home doesn't hinge on selling yours, which matters when other buyers want the same house.

What usually stops people is money. Your equity is locked in your current home until it sells, and most families can't, or don't want to, carry two mortgages at once. That's exactly the problem an equity advance is built to solve. Not sure which path fits you? Answer three quick questions below.

This is general guidance, not a loan approval. Your equity, income, and the home you're buying all matter, and that's what a quick conversation with a lender and Jacob Stark sorts out.

Which of the 5 Ways to Move Up Does Jacob Stark Start With?

Jacob Stark starts with the equity advance, because it's the smoothest path for most homeowners: one move, no showings to live through, and a strong offer on the next home. It isn't the cheapest option, but many people happily pay for that kind of convenience. From there, the options get cheaper but ask more of you in timing, qualifying, or stress.

1. Use an equity advance (buy-before-you-sell program)

An equity advance unlocks part of your current home's equity before it sells. With the program Jacob Stark uses most often, the advance is interest-free and covers the down payment and closing costs on the new home, plus a few months of payments on the old home if there's enough equity left over.

The biggest benefit for many homeowners: it can keep your old mortgage from counting against you when you qualify for the new one. That's what stops most people from buying first, and it's why this option works for homeowners who could never carry two mortgages on paper.

Here's how it plays out. You make an offer that doesn't depend on selling first, so it competes like a buyer without a home to sell. You close and move in. Your old home is refreshed, cleaned, and staged, then listed and sold, and the advance is repaid from your proceeds. If the old home hasn't sold by the program's deadline (about four months), the program buys it for the amount needed to pay off your loans, and you get any upside when it resells, minus costs.

Best for: homeowners with at least about 20% equity who want to move once and skip living through showings. Trade-off: a program fee of about 2–3% of the sale price (up to 5% with some programs), and you keep paying the old mortgage unless the advance has room to cover it. Some programs also exclude FHA loans on the new home. See how buying before you sell works, step by step, and read the honest catches before you sign up for a program.

Equity advances are offered by third-party partner companies. Equity advance eligibility is subject to approval and is not guaranteed. Advance amounts depend on your home equity and qualification.

2. Open a HELOC before you list

A home equity line of credit lets you borrow against your current home's equity and use it as the down payment on the next one. You pay it off when the old home sells. HELOC rates are usually variable, and lately they've run close to 30-year mortgage rates, per Bankrate and Freddie Mac.

Best for: homeowners with solid equity and income who can qualify with both payments counted. Trade-off: the HELOC payment counts when you qualify for the new mortgage, and timing matters. Most lenders won't open a HELOC on a home that's listed for sale, so it has to be in place before your listing goes live. According to NerdWallet, most lenders let you borrow up to 85% of your home's value minus what you owe, and closing costs run from nothing to 2–5% of the line.

3. Use a bridge loan

A bridge loan is a short-term loan secured by your current home that covers the down payment on the next one. According to NerdWallet, you can typically borrow up to 80% of the combined value of both homes, usually for six months to a year, at higher rates than a regular mortgage, plus closing costs and fees that "can cost thousands."

Best for: homeowners whose home is already listed or under contract, or who can't get a HELOC in time. Trade-off: it's usually the most expensive way to borrow on this list, and the payment counts against you when you qualify for the new mortgage. A little planning can keep a bridge loan from being your only option: starting an equity advance application early, or opening a HELOC before you list, gives you better choices.

4. Make an offer contingent on selling your home

This is what many homeowners do. Colorado's standard purchase contract has a section built for it. Section 10.7 of the Colorado Real Estate Commission's residential contract (mandatory since January 1, 2026), titled "Conditional Upon Sale of Property," lets you cancel if your current home hasn't sold and closed by a deadline you negotiate. Miss the deadline without sending notice, and you've waived the right to cancel.

Whether a seller says yes depends on the market. Right now, there's a lot of inventory in the Denver area. In September 2026, more than half of active listings in every South Denver Metro city (53–64%) had already cut their price, per REcolorado MLS data, so some sellers will consider a contingent offer. But expect them to want your home ready to list, or already listed, plus a short deadline and the right to keep showing their home for a backup offer. That means prepping, listing, and showing your home while you're trying to close on the next one, and that timing stress isn't for everyone.

Best for: homeowners whose home is ready to go and who are comfortable with a tight timeline. Trade-off: it's the cheapest route but the weakest offer, and some sellers won't accept it at all.

5. Sell first, then rent back or rent short-term

You list and sell your current home, and the proceeds fund the next down payment. To avoid moving twice, you ask the buyer for a rent-back, where you stay after closing while you buy and close on the next home. Colorado has a standard form for this, the Real Estate Commission's Post-Closing Occupancy Agreement:

• 60 days is the limit when the buyer will live in the home. Anything longer needs a full lease, and most buyers' loans require them to move in within about 60 days anyway. Some lenders allow only 30.
• Rent is negotiated. It's sometimes waived in exchange for a deposit, and sometimes set to cover the buyer's daily cost of owning the home.
• The deposit is currently capped at two months' rent. A new state law, SB26-054, removes that cap for rent-backs starting January 1, 2027.

The catch is the market. With this much inventory, buyers have plenty of homes they can move into right away, and many won't agree to wait 30 to 60 days. If yours won't, you'll likely rent short-term or stay with family in between. That means moving twice and possibly paying rent on top of everything else.

Best for: homeowners who need all of their equity for the next home, or who can't qualify for the new mortgage until the old one is sold. Trade-off: you're shopping on a deadline, and you may end up moving twice.

What Does Each Option Really Cost?

Here's an illustrative family (not a real client) selling a single-family home at Littleton's 2026 median and buying at Highlands Ranch's, using year-to-date figures through August from the Colorado Association of REALTORS®:

• Selling in Littleton: $710,000 sale price, $340,000 mortgage balance (our assumption), and about 8% in selling costs (a typical commission plus seller closing costs). Net proceeds: roughly $313,200.
• Buying in Highlands Ranch: $755,000 purchase, 20% down ($151,000) plus about 2.5% in closing costs. Cash needed at closing: roughly $169,900.
• The new payment: a $604,000 loan at Freddie Mac's 7.40% average 30-year rate (week of October 15, 2026) is about $4,180 a month in principal and interest, before taxes, insurance, and HOA.

The equity is there. The problem is that the $313,200 isn't available until the Littleton home closes, and the Highlands Ranch seller wants $169,900 at their closing. Here's what bridging that gap costs each way, assuming the Littleton home takes 2 to 3.5 months to sell and close and costs $2,600 a month to carry (our assumption for the old mortgage, taxes, and insurance).

Two things jump out. First, the cheapest options on paper (contingent offers and selling first) are cheap because they push the cost somewhere else: a weaker offer, a tight deadline, or a second move. Second, a HELOC only works if the line is big enough. Lenders usually cap you at 80–85% of your home's value minus what you owe. This family clears that easily, but a homeowner with less equity might not.

The equity advance usually has the highest price tag, and it's the only path here that lets you buy first without adding a payment that counts against you when you qualify. Whether it's worth it depends on your priorities, not just the math. For many homeowners, moving once, skipping months of showings with kids at home, and making a stronger offer on the right house are worth paying for. In Jacob Stark's experience, the fee is often offset by that stronger offer, a single move with no storage or short-term rental, and a refreshed, cleaned, and staged home that shows at its best. If keeping costs as low as possible matters most to you, another path may fit better.

When Does Jacob Stark Tell Homeowners to Sell First?

Buying first is the better experience for most people, but it isn't right for everyone. Jacob Stark recommends selling first when:

• You have less than about 20% equity. Most equity advances, HELOCs, and bridge loans need more room than that.
• The next home only works with every dollar of equity. If a lower-than-expected sale price would break the purchase, lock in the sale first.
• Keeping costs as low as possible matters more than convenience, and you're comfortable with a tighter timeline.
• You're flexible on timing and a short-term rental or a few weeks with family doesn't bother you.

Either way, the fees and the trade-offs should be laid out side by side before you decide. That's the conversation, not a sales pitch.

How Does Your City's Market Speed Change the Answer?

Speed matters on both ends. How fast your current home sells sets how long you carry two homes. How fast homes sell where you're buying tells you how much room you have to negotiate. Here's how single-family homes in South Denver Metro cities compared from January through August 2026, per the Colorado Association of REALTORS®:

• Littleton: 38 days on market, 99.3% of list price received.
• Highlands Ranch: 34 days, 99.6% of list price.
• Centennial: 31 days, 99.5% of list price.
• Englewood: 36 days, 99.1% of list price.
• Parker: 42 days, 99.1% of list price.

Fall has been slower than those year-to-date numbers suggest. Metro-wide, the DMAR September 2026 Market Trends Report put months of inventory at 4.76, with the most active listings for a September since 2011. That gives buyers more room to negotiate, including room to ask for a contingency.

For sellers, a slower market rewards preparation. A home that's prepped well and priced right shouldn't sit, even now. Jacob Stark's strategic approach to prep and pricing often beats these market averages, which keeps the carrying time on a buy-first move as short as possible.

What Mistakes Cost Homeowners the Most?

• Assuming every seller will take a contingent offer. Some won't, even in this market. Have a plan B before you find the house.
• Counting on a long rent-back. With this much inventory, many buyers want to move in right away.
• Waiting too long to explore buy-first options. Equity advance approvals and HELOCs take time to set up. Starting early keeps more doors open and keeps a bridge loan from being your only choice.
• Overpricing the old home after buying the new one. Every extra month on the market is another month of carrying it.
• Budgeting for a perfect timeline. Closings slip. Build in a cushion of a few weeks.

Frequently Asked Questions

What is an equity advance program?

An equity advance program lets you tap part of your current home's equity before it sells, usually to cover the down payment and closing costs on your next home. You buy first, move once, and then your old home is prepped, listed, and sold, with the advance repaid from the proceeds. Programs typically require at least 20% equity and charge a fee of about 2–3% of the sale price. Some also keep your old mortgage from counting against you when you qualify for the new loan. Jacob Stark, a South Denver Metro REALTOR®, can tell you whether you're likely to qualify.

How much does a buy-before-you-sell program cost?

Most charge a program fee of about 2–3% of your current home's sale price (some charge up to 5%), on top of normal selling costs. In our Littleton-to-Highlands Ranch example, that fee plus a few months of carrying the old home came to roughly $19,400–$30,400. Many homeowners find the convenience worth it: one move, no showings to live through, and a stronger offer on the next home. Eligibility and terms vary by program.

Can I buy a house before selling mine?

Often, yes. You need a way to cover the down payment before your current home sells and a way to qualify for the new mortgage. The usual paths are an equity advance program, a HELOC opened before you list, a bridge loan, or savings. With an equity advance, some programs keep your old mortgage from counting against you when you qualify, which is what makes buying first possible for many homeowners who can't carry two mortgages.

What happens if my house doesn't sell after I buy?

You keep paying your old home's costs while it's listed, so preparing and pricing it well matters. With an equity advance, programs typically set a deadline of about four months; if the home hasn't sold by then, the program buys it for the amount needed to pay off your loans, and you get any upside when it resells, minus costs. With a HELOC or bridge loan, there's no backstop, so you carry both homes until it sells.

Can I rent back my home after selling in Colorado?

Yes, if the buyer agrees. Colorado's standard Post-Closing Occupancy Agreement lets a seller stay up to 60 days after closing when the buyer will live in the home, with rent and deposit negotiated. In a market with plenty of homes for sale, many buyers won't wait that long to move in, so have a backup plan such as a short-term rental.

Wondering if you could buy first? In 30 minutes, Jacob Stark will look at your home, your equity, and your timeline. You'll leave knowing whether buying first is possible for you, which path fits, and roughly what it costs. If the answer is "sell first" or "not this year," that's a perfectly good outcome.
