Sink Hole - Investigation

[Steve Kordish]

Hello all, I just went under contract on a home in Pasco county FL that has a report of "sink hole" activity in 2010. I have a good amt of experience with fix/flips but I have never flipped a home with a sink hole. This sink hole was never remediated and there are no visible signs of cracks, settling, etc. A written estimate from 'Sinkhole Titan", from November 2021 to pin the home, was provided to me by the owner and that cost was worked into my numbers. I'm not concerned about selling a home with a properly remediated sinkhole along with the appropriate engineering sign-off, my question is, does anyone know of an engineering firm or company that can further investigate the sinkhole to determine exactly where and how large? I'd like to find someone who doesn't stand to profit from the repair work. I also want to verify there actually is an issue, since we had a whole lot of shenanigans going on around here 2010 regarding fraudulent claims and insurance money. Once again, this house is in Pasco county FL( New Port Richey) - any referrals would be greatly appreciated!
