Best way to find foreclosures/ preforeclosures in Charlotte (looking for primary residence)

[Coley Mitchell]

Hello - I want to find a good source to locate for foreclosures (preferably pre-foreclosures) in Charlotte, NC. Considering making a purchase with FHA loan as primary residence for 2 years or so if I can find a good enough deal.

Is driving neighborhoods, locating empty houses, writing letters, etc. the best way or is there some sort of service that specializes in pre-foreclosure listings? Also, at what point should I get a realtor involved?

Any input would be appreciated - thanks!
