As retirement approaches, many people start thinking about downsizing, relocating, or moving into a retirement community. The instinct is understandable — simplify life, lower expenses, and reduce maintenance. But there’s a hidden cost that’s often overlooked: selling too early can eliminate one of the most powerful tax benefits in the entire code.
That benefit is the step-up in basis, and for many families, it’s the difference between paying a large capital gains tax bill and paying none at all.
Why Selling Too Early Can Be Expensive
If you bought your home decades ago, the appreciation is often significant. Sell during your lifetime and you may owe capital gains tax on that increase (after the $250k/$500k exclusion). Hold the home until death, however, and the property’s basis resets to its fair market value at that time. Your heirs can often sell the home with little to no tax owed.
For a home purchased for $180,000 and now worth $780,000, that step-up could eliminate roughly $100,000 of taxable gain, and the $15,000 capital gains tax that comes with it.
It’s one of the most overlooked tools for preserving family wealth.
But What If You Do Want to Move? You Still Have Options
Keeping the home doesn’t require living in it.
If downsizing or a retirement community makes sense from a lifestyle standpoint, you can still preserve the step-up by simply retaining ownership.
Smart options include:
- Renting the home
You keep ownership, generate income, and still preserve the step-up. Even better, any accumulated depreciation (and the depreciation recapture tax that normally comes with it) is wiped out at death. - Converting it into a vacation property
Use it seasonally, let family enjoy it, or keep it lightly used; the step-up still applies. - Leaving it vacant temporarily
Even if the home sits unused, the tax benefit remains intact as long as you continue to own it.
In short: you don’t have to choose between lifestyle flexibility and smart tax planning.
The Bottom Line
Selling a highly appreciated home late in life can unintentionally trigger avoidable taxes. Before you downsize, move closer to family, or transition into a retirement community, it’s worth understanding the tradeoff. In many cases, retaining the home—even if you no longer live in it—can preserve a major tax advantage for your heirs.
