Why Your Parents (Or You) Won't Sell That Big House – And What to Do About It
Here's a story you might recognize: Joel and Kathryn Friedman are empty nesters ready to downsize. Their kids are grown, the house feels too big, and the maintenance is getting overwhelming. But they won't sell. Why? Because selling would trigger a massive capital gains tax bill – 20% on profits over $500,000. And they're not alone. About 34% of U.S. homeowners are sitting on gains that would put them in the same situation.
This is why you can't find a decent family home to buy, and why your parents are rattling around in a house that's way too big for them. Empty-nest boomers own twice as many 3+ bedroom homes as millennials with kids. Until they start selling, inventory in established neighborhoods stays tight, and prices stay high. Everyone wants to move, but nobody wants to pay Uncle Sam.
Here's how the tax reality works: If you're married, you can exclude up to $500,000 in capital gains when you sell your primary residence ($250,000 if you're single). Anything above that gets taxed at 20%, plus a 3.8% net investment income tax if your income is high enough. So if you bought your house for $200,000 thirty years ago and it's worth $1.2 million today, you're looking at taxes on $500,000 of gains. That's potentially $119,000 in federal taxes alone, not counting state taxes.
If you're the homeowner facing this situation, talk to a tax professional before making any decisions. There are strategies that might help – 1031 exchanges, installment sales, charitable remainder trusts. None eliminate the tax, but they might reduce it or spread it out. Also consider your total financial picture: if staying in your current home means spending $30,000 a year on maintenance, property taxes, and utilities you don't need, the math might still work out despite the tax bill.
If you're an adult child watching your parents struggle with this decision, have the conversation. Your parents might be staying put because they think they have to, not because they want to. Help them understand their options, including the real costs of staying versus the tax costs of selling. Connect them with professionals who can lay out strategies they might not know about.
The current tax rules are keeping people in homes they don't want, which keeps those homes away from families who need them. It's not good for anyone. But waiting for perfect tax policy is like waiting for perfect weather – you might be waiting a long time. Life keeps happening while you're waiting for the rules to change.
If you're a boomer thinking about downsizing, don't let tax fear paralyze you. Get professional advice, run the real numbers, and remember that the goal isn't to minimize taxes – it's to maximize your happiness and financial security. Sometimes the best financial decision isn't the one that saves the most money – it's the one that gives you the life you actually want to live.
