Newbie Determining Repair Cost?

[Eric DeVito]

Hello al, my question is since I am new to the investing business when I go to check out properties I am interested in how do I determine as a newbie what needs to be repaired and what doesn't? Will my Real Estate agent help me? Should I have a appraiser walk through with me or an inspector? If so at what point do I have these people walk through the home with me? I can't have them coming to every home I am somewhat interested in.  Any tips/advice much appreciated.
