ANYONE WITH EXPERIENCE WITH PRE FABRICATED SFH? Some Insight Would Be Helpful

[Tia Ricketts]

I am a fairly new (2.5 years) BRRR investor in the Pittsburgh Area and I've found myself in a tough situation where a property I bought at the sheriff sale (sight unseen …. I know 🫠) was condemned.
I just had a structural engineer and a professional builder come out and the general advice is to tear down the structure due to major foundation issues that will be costly to address.

I am now considering replacing the structure with a pre-fabricated SFH due to financial restraints. 
Has anyone used this option before? Any recommendations for companies that are easy to work with? Reasonable prices? Reasonable turnaround time for getting the pre fab onto the job site? 
I have so many questions!
