The way I’m reading it, A would be the whole quadrant and B would just be that specific stripe. I don’t know if A includes B, or excludes it though. I also can’t tell if the stripes are just that specific box, or the entirety of the countries that fall partway in the box; is B just that rectangle or all of the U.S., Canada, and Mexico?
“A” would be your pick, but the odds aren’t great.
Everyone in here is ripping these people and ignoring their actual situation and the problem it creates for all of us.
If their profit is that high, they bought decades ago, when the price of a home like this was in the reach of a normal high paid professional. Decades later after raising kids, paying for college, and saving normally, they might not be wealthy, or even rich in cash and investments. This house might be a large majority of their net worth. And guess what? Anywhere they want to move is going to have had the same crazy inflation as their current home. Why would they sell when, after taxes, any place they buy with what’s left will be a major step down.
And for their specific example, 55-plus communities usually sell for much less per sqft because they come with huge HOA fees to fund all their amenities. Generally people expect to pay these fees with the difference between the sale of their old home and the new one. They might not be able to afford the HOA fees after taxes.
They’ve got two choices: They can sell and either make up the taxes with their savings, drastically reducing their standard of living (if they’re even able to do that, don’t forget if they take 700k out of a 401k all at once they’ll get wrecked in taxes that year) or move somewhere shittier with the after tax proceeds. Or stay in their too large home, keeping it off the market. Edit: I forgot a commonly used option; keep the old place, rent it out and charge enough to pay the mortgage on the new place and property tax, HOAs, and maintenance on both (and why not a little profit too?), further fucking the market.
Empty nesters staying in their family homes keeps them off the market driving up the costs for young families and everyone else in the market as a whole.
As far as a solution goes, I’m not a fan of a larger exemption. I would advocate a special account for home sale profits, kind of like an HSA or a 529, that could only be used tax free for qualified expenses like purchasing a home, property taxes, and HOAs. But anything that encourages older people to leave their too-large homes for something more suitable would help the market for everyone.
If you can’t get past “boo hoo rich people problems,” cut the numbers in half, or more. The problem persists. In California a profit in excess of 500k (250k for a single person) after decades of living in a modest family home is not at all rare. Many normal people who are not rich by any stretch find themselves in this situation.
My MiL was in this exact situation (selling and moving to a 55-plus community), and she is not rich. To make the numbers work I had to make her investments higher risk/higher reward than they should be for her age to allow for larger withdrawals. Luckily she has my wife and I to make up the difference if it goes tits-up, but not everyone has that luxury.
