ooh, forgot about housing. Is there a reason you are choosing Riverton? If you are looking for foreclosures you may want to look at Draper. Lots of people bought homes they could not afford and are now in foreclosure. We thought about that too but because there are so many foreclosures in the newer areas we felt the home values would fall faster. We bought in Sandy in a neighborhood called Pepperwood. Absolutely love it! There are some great deals to be had in Pepperwood right now also. It's the only community we felt had a similarity to the East coast feel, lots of trees, decent yards and spectacular views of the mountains. A big seller was the recreation center with basketball, tennis, volley ball courts, a pool, small playground and lots of space for kids to play. Also, all of the cul-de-sacs are connected by bike paths to make getting around for the kids easier and safer. It's also a gated community. It's a pretty easy commute to SL also.
Check out zillow.com and of course realtor.com. Zillow will let you zoom in on the house, yard, street etc.. It was a great tool when we were looking from the East. You really just have to list your priorities first. Bedrooms should not be a problem because houses have a lot of them out here - and finished basements are very common. You have to decide more if you want a view, a yard, how many car garage, do you want to be in the valley or the mountains...stuff like that. The valley is a little more congested but you get less snow. We liked the neighborhoods off of Wasatch Blvd. Nice homes, a lot of different price ranges and some great views. If you're moving from the East coast you at least need a great view!

Good luck again!
