Can you give a more precise link? Your link goes to the toplevel of the site and I couldn’t find this. I thought the 3.8% was levied on investment income. I guess I could see that extended to capital gains on a home, which for properties held for a long time, could be fairly significant.

Nope. This is a change to increase the capital gains tax rate for sales of home prices above the amount exempt from the cap gains tax. It isn't from the first dollar unless you have a zero cost basis and make a large income. Most home sales probably won't be hit at all.
