Rental property in Orange Count NY

[Kemona Palmer]

My partner and I have been looking to get a rental property in Orange County NY (Port Jervis or Highland Falls areas.  We have seen several properities that we like and the price is within our price range - 250k.  Being that this will be our first rental property, we don't want to spend a great deal out the gate.  We are looking at multi-family places.  We believe both areas to be good rental areas.  Many homes in the Port Jervis area are older homes.  We are new to this and just want to know if anyone can give us some advice on what to look out for and how can we tell if an area is a good location to invest in?
