Does anyone know how to find deals on low-end houses in high-end neighborhoods?

[Matthew Fidler]

I am a new real-estate investor looking at flipping properties in a higher end neighborhood. I was hoping someone with some experience would be able to answer a few questions I have, such as: What kind of deal finding strategies are most efficient in areas like these? How do you approach an owner when asking them to sell their property? What kind of database should I use to keep track of my leads and client base? Any advice would be very much appreciated.

Thank you.
