That seems reasonable to me.
In regard to the closing of so-called loopholes, I think you might want to amend your use of language in the future. I think it's “closing advantages surrounding the capital gains exemption on the sale of a principal residence”. I've had a number of people who are quite concerned. For this year's tax, people had to note if they sold their principal residence, and I've had people ask me, “Where's this going?” Can you go over that one particular area again, and the page it's on?
