contractor when viewing houses to calculate rehab costs

[Holly Rogers]

Hello!  I am doing my first flip and I have a couple of houses I am interested in making an offer on.  I need a general contractor to walk through the houses with me to tell me what the costs of the rehab will be before I make an offer.  These properties are in the NJ tinicum area and PA upper black eddy area.  I need someone who knows what they are doing and can give me a good estimate of real repairs that need to be done.  Does anyone have suggestions of how to go about this?  A. does anyone have a good contractor?  B. Do people usually take a contractor on site visits prior to making an offer and do they pay the general contractor for this visit, or is it built into the ultimate work? C. if the answer to B is that you pay the contractor for each visit, doesn't that get really expensive?

appreciate the help!
