Why Colorado Retirees Are Buying Bigger Homes With Their Kids Instead of Downsizing

For decades, downsizing was a retirement rite of passage: sell the big family home, buy something smaller, pocket the difference, and simplify. Along the Colorado Front Range in 2026, that math has quietly stopped working—and a surprising number of retirees are doing the opposite. They're buying bigger homes, often alongside their adult children, and treating it as an early inheritance.

It's not nostalgia. It's a response to a housing market that has turned a simple lifestyle decision into a full-blown family-finance calculation.

The Downsizing Payoff Has Shrunk

The old playbook assumed a smaller home would cost meaningfully less than the family house. That assumption has broken down. In much of the country, even a modest starter home now pushes toward seven figures, so the "smaller, cheaper" replacement isn't nearly as cheap as it used to be. Once a longtime owner sells, buys, moves, and settles up, much of the equity they hoped to preserve can evaporate.

Three forces are squeezing the payoff in particular:

• Mortgage rate lock-in. A large majority of existing mortgages carry rates below 6%, and roughly half are at or under 4%, according to realtor.com's analysis of federal mortgage data. Selling often means trading a cheap, locked-in loan for a much pricier one. A 2024 Federal Reserve paper found this lock-in explained a big share of the drop in homeowner mobility.

• Capital gains exposure. The IRS exclusion—up to $250,000 in gains for singles, $500,000 for married couples filing jointly—hasn't changed since 1997, even as Colorado home values have soared. The National Association of Realtors estimates roughly 15% of owner households now sit on gains above their exclusion. The very appreciation that built your wealth can become a penalty when you try to unlock it.
• The real cost of moving. A recent realtor.com study pegged the average move at around $17,000 once closing costs, movers, and prepping the new place are tallied. We almost always underestimate that number.

Add it up and "sell big, buy small, pocket the difference" can turn into "sell big, buy small, and barely break even."

From Lifestyle Choice to Wealth-Transfer Strategy

Here's the shift we're seeing across the Front Range, from Fort Collins through the Denver metro to Colorado Springs. Instead of shrinking their footprint and sitting on equity for later, some retirees are putting that equity to work now—by buying a larger home together with their adult kids.

The logic is compelling on both sides. Younger buyers are boxed out by high prices, elevated rates, rent, and student debt; realtor.com's economists estimate well over a million potential Gen Z and millennial households went missing from the market in a single recent year. Meanwhile their parents are sitting on exactly the kind of housing wealth those kids can't build on their own.

Combine them and the equation changes. The retiree brings accumulated equity; the adult child brings current income. Together that's frequently a stronger lending profile than either side alone—and it can unlock a home neither could qualify for independently.

The timing is the real prize. An inheritance that arrives when a child is in their twenties or thirties and trying to buy is worth far more than the same money decades later. Research from realtor.com found that buying a first home young can translate into roughly 22.5%—about $119,000—more net worth by age 50 than waiting another decade. In other words, the wealth transfers while the next generation needs it most.

This Is Multigenerational Living—And It's Our Specialty

What this trend really describes is multigenerational living: parents and adult children (and sometimes grandkids) under one larger, well-designed roof. Done right, it cuts the cost of running two households, keeps family close, and moves an inheritance forward by 20 years.

It also demands the right house. That means flexible floor plans, a true second living suite or a basement that can be finished for privacy, dual primary options, and—where the lot allows—an accessory dwelling unit (ADU). These are exactly the property types The Kenna Real Estate Group team works in every week across the Front Range, and they're not always easy to find or evaluate.

A Construction-Trained Eye on a Bigger Decision

A multigenerational purchase is far more than a square-footage question—it's a question of what a home will actually cost to own, adapt, and share over the next 20 years.

With more than 25 years in real estate and 13 years as a multifamily construction superintendent, I read these homes differently. Can this floor plan be split for two households without a teardown? Is an ADU feasible on this lot, and what will it really cost to build? Are the doorways, entries, and primary suite set up for aging in place? Which "great deal" is actually hiding expensive problems? That's the layer most buyers don't see until the bills arrive.

The Risk Nobody Talks About: The Paperwork, Not the Mortgage

Buying bigger together is not automatically better. A larger home brings higher property taxes, insurance, utilities, and maintenance. But experts agree the biggest risk isn't the loan—it's leaving the family agreement undefined.

Before the first box is packed, a multigenerational purchase needs clear, written answers to questions like:

• How is title held, and what does each person actually own?
• Who contributes what to the down payment and the monthly costs?
• Who covers the surprise repair, the new roof, the property tax increase?
• What happens if someone wants out, needs long-term care, divorces, loses a job, or passes away?
• How does the home transfer to the next generation when the time comes?

Treat it like the inheritance it is and protect it accordingly. The arrangements that fail rarely fail on the financing—they fail because nobody put the terms in writing. We help families bring in the right attorney and lender early so the plan is solid before anyone moves in.

So—Should You Upsize, Downsize, or Stay Put?

There's no universal answer, only the right answer for your numbers and your family. For some Front Range retirees, a larger multigenerational home is a powerful early inheritance. For others, the smartest move is staying in a paid-off home and investing in age-in-place upgrades instead of absorbing $17,000 in moving costs.

The only honest way to decide is a side-by-side comparison: your current home versus the target home—total monthly cost, equity position, tax exposure, transaction costs, and how the space actually fits the life (and family) you want. When you can see the real numbers next to each other, the decision tends to make itself.
