re: neighborhoods in Baton Rouge for young married couple

If you think you will be moving again in a few years my advice as a 5 time BR home owner would be to get in a neighborhood with older homes where there is less parity between houses. New subdivisions with very similar styles and plans tend to pit houses against each other and hurt sales and property value growth. Even if you are the type that will fix up and maintain your house.
Good Luck.
