Negotiation after inspection

[Assad Oskuei]

Hello everyone, My first renal property investment. 

Had inspection done yesterday. 

1) The roof is 15-20 years old. A few broken shingles here and there, curled up shingles, damaged skylight frame window.

2) Mold noted on the basement walls. 

Its a 5400 sq 3 unit MFH. Built in 1930. 

Would you get a GC and give you an estimate of repairs and ask for credit based on that? Do I have any negotiating power here?  Would you get a mold specialist? 

Thanks in advance.
