US housing prices are so out of whack you'd be surprised. I live in the metro Washington D.C. area and housing prices have been rising at least 10% per year here in the last 4 years. I used to work at a mortgage company, so I have a pretty good idea about housing prices across the US and lemme tell ya, they're skyrocketing. I advised my mother to buy a townhouse three years ago, and somehow I actually convinced her to do so. Pretty small actually, 2 bedrooms, 2 full baths, finished basement. She paid $112,000 in April 2000. It is a corner townhome though so it's a tad bigger than the rest. The house two houses down just sold last week...not a corner townhouse, no deck like my mother's, and a bit smaller...selling price: $198,000. Single-family homes here go for at least $350,000 plus, and that's usually for a home that's easily a good hour-hour and a half commute from work unless you're extremely lucky.
Thinking of moving to Boston? Be prepared to pay, and pay big, to get a home. I strongly recommend the outskirts of town. Mortgage prices are showing a tendancy to rise now, after a 3 year period of almost record lows. I'd strongly advise against Adjustable-rate mortgages because chances are they won't go down lower than this for a while now, but then again I've always hated ARM's. Best of luck on your search.
