I am attaching the Selma city website below. Selma is a charming small town about 30 to 45 min from Raleigh. I guess it really depends on what you are looking for in a place to live. LIke most small towns I would say just make sure they have enough of what you like to do or are at least close to somewhere that does.
If you do not already have a relocation qualified agent in the Selma area and need on just let me know.
It appears that you can finance a NEW mobile home through USDA but they have a list of approved vendors. I have attached the link to the vendors belowfc. Also, your lender must be a USDA approved lender. The USDA also has a great website with informantion on their loan programs and the eligiblity requirements.
