Oh, you bought your house a decade ago. In your 20's too, which either means you live in a cheap shit hole, or mommy and daddy's money helped you out (either directly, or by shielding you from things like student debt).
I'm assuming that your house is a Patrick Star style rock, and you've been living under it for this whole time, because house prices are up 60%+ since then, in some places more than doubling, all while wages stagnate.
If you're paying a mortgage on a house you bought in your 20's, you aren't going to be affected by the taxes on unrealized gains exceeding $100,000,000, because if you had that kind of wealth you wouldn't have a mortgage...
