Just my two cents. I am by no means a seasoned investor. I have however walked away from two deals, they would have each potentially been my "1st" deal. The 1st of the two the chimney was separating from the house, SFR, and who know how much that would have cost to fix, found during inspection at a cost of $350. Second deal was a duplex that bad sewer line out to the main city sewer. The seller tried to lie about it and my realtor at the time who is no longer my realtor got mad at the plumber who told me the truth and called him and gave him an earful because he had informed me. This cost me about $600 in inspection fees. So total I invested almost $1000.00 and had no deals, however, now I also don't have any headaches that may have come with either of those two deals.
I took about 8 months off from looking then I ended up finding a little gem in the rough.
The thing I have learned here from BP, and life, is to go with your gut. If you don't trust it walk. No harm in this. The money you are out for the appraisal and inspection are just part of doing business. This money spent could possibly be saving you thousands upon thousands of dollars in potential headaches later on. One suggestion is to partner up with a local in the area who might be on BP and try to sort something out on a future deal. People on here are beyond willing to assist, especially if it means maybe partnering on a deal. Remember half a deal is better than the whole of a no deal. Also don't rush it. There will always be more deals.
Good luck friend. Keep us posted.
