The trouble with counting on the worth of your house as part of your net worth for retirement purposes is that many times, at least around here, it takes forever to sell a house; and even if you do manage to sell it, you still have to live somewhere. I don't know what my house is worth, really, but it's the cheapest place for me to live, even considering repairs and property taxes, etc., because it's paid for. There are houses in my neighborhood that have been on the market for over 2 years. Real estate is VERY slow here. My sister lives in a decent, but very little bitty apartment not too far from me and she pays more than I do for housing, and her rent keeps going up every year.
