gzz, we had never planned to sell our properties, since we’re very happy with the cash flow and other benefits, and always knew we’d be leaving it all to the kids, as you plan to do, but I can understand how you might want to sell, especially if you’re not happy in your primary.
Imo, whatever you have to do to make it work will be worth it. As has been mentioned, you have some options, and even with a cap gains hit–you’d still be way ahead–and you and your family would be able to enjoy your lives in a home you love. Believe me, loving the home you live in is definitely one of the best things in this life.
