As a resident of the 5T for over 25 years, i must say that it is a wonderful area to live in. Granted some parts are pricey, but you can buy a house at a decent price. Many young couples have moved to Inwood, North Woodmere, parts of Cedarhurst and Woodmere. There is even talk of a group moving to Valley Stream. All of these areas are relatively close to the shopping and restaurants in the 5T.
