At the moment I'm currently in the process of looking for an owner occupied duplex relatively close to my current work place in Westmoreland county to get out of the renting world now the I'm more familiar with the area. 

@Will BarnardWell your not harming anyone with asbestos shingles.

Our agent said that since we already did the inspection, there is no harm in putting an offer at our comfortable price.

There certainly is no harm in trying though. 

If anyway I can report about him not providing w9 or 1099 or anything, atleast this should not harm other people like me.I totally agree at the time of selecting the handyman, I have asked verbally if he can provide receipt with tax ID/ssn and he said yes, but after work he is not, and there is nothing in writing which confirm he agreed upon to provide the same/tax ID.Its my fault.

You do not need to close on all the properties you identify so if a property falls through, no harm no foul.

Were you harmed by them?  

Check out a few local credit unions and see what they'll offer - no harm in asking. 

Does the person doing them need to be bonded or insured since they will be climbing a ladder & could fall & harm themselves on your property

Should I use some land mark or workplace as a pin point (Hospital, stadium...etc) Do you have any pocket listing around these area??
