Hello C. Perlosky,
Ballantyne Country Club (22 active listings) or Kensington Forest or Allyson Park or Ardrey Commons are beautiful with plenty of custom homes to choose from, especially in the Spring. For a custom home in a great neighborhood with great amenities, you can expect to pay $400,000 and up.
For semi-custom homes, you can find housing for $325,000 and up in good neighborhoods. If you can live on a smaller lot, then you can find even more housing. There are plenty of apartments to live in temporarily too.
If you want more specifics, then email me your criteria.
