New York - Lower Hudson Valley

Any rehabbers doing business in the NYC suburbs. Orange, Rockland, Dutchess, Putnam county areas. I am looking to do rehabs, have found a few properties that may be deals. Mostly around Monroe. Anybody here familiar with the market in this area, are starter homes $150-300K selling. I see alot of listings on the MLS, but how many are actually selling at or close to asking price, how long are they sitting before getting an offer.

I have some $$ to invest, I can find properties about 60-70% below market, and do most of the work myself, How likely is it that I can then sell quickly. I dont want to invest $200K of my money for $6K in profit when its all over.
