100k to invest east coast area

Hi all, I have been slowly looking to get into the real estate market for the last year or two. My main interest in the begiining in cash flow, which then can turn into appreciation by either selling off, and buying into a new market or if the area turns around.

I have about 100k to invest on the east coast, and am wondering what are some affluent/good areas to look into. I have began my search, but wondering if there are some other areas I should keep my eyes on. Any other tips would be greatly appreciated.

Thank you.
