There are many things to consider when buying a house for short term (3 years). The interest rates are very low and a very good time to buy. However, if you plan to sell in three years, this may not be a good move. We have many military families that are up-side-down with houses in the area. They have been transferred to other bases, and their house is still on the market here in the New Bern/Havelock area. We have hundreds of houses that have been on the market for a year or more. What will be market be in three years? Who knows? There may be an increase in value, but maybe not enough to pay the selling expenses. I suggest that you talk with some military families and get their views. If I can help you, please give me a call.
