John and Carly took a leap of faith five months ago and moved from Florida to Nashville, where John hopes to launch a music career. Now that the lease is up on their tiny two-bedroom town house, they've decided to make ''Music City USA'' their permanent home, and are looking to buy a place as close to the happening downtown scene as possible. Both are eager to find a place with a bigger kitchen, and extra rooms for John to practice his guitar and Carly to work on her crafts. With a budget of $330,000, can the couple find a home that has the kind of architectural charm John loves, along with the practical features Carly demands?
