You ask about the best place to buy....Bellevue is closest to Offutt so would offer the shortest commute to work if you're working on base. There are a range of homes in Bellevue, from older established neighborhoods to new developments.
Papillion was voted the #6 place in America to live by Money Magazine last year. Here is the article: http://money.cnn.com/magazines/moneymag/bplive/2007/ . There is also a good range of homes to choose from, from older to newer in every price range.
LaVista is a bit further away from the base, but is closer to Omaha, so if you have another member of the family working there it might be a convenient location for both of you.
Schools in all 3 areas have excellent reputations. Here are some links to check out concerning the schools.
If you'd like further information or to see listings of local area homes, please contact me directly.
