Should I go to small claims court

Hey guys. I went to put an offer on a house that seemed to be in good condition and pretty on the inside. The inspector found major foundation work being needed, and none of the plumbing,HVAC,or electricity that had been completely redone had permits to go with them. Multiple things are out of code.

We have signed paperwork from the seller stating that the house didn't have foundation problems. Their realtor gave mine a screenshot of the email that was dated 2 months ago from a foundation inspector coming through and quoting 15-20k in repairs. The screenshot has the owner's emails, the date, and the companies name. I'm out $900 in inspector fees, which are the only thing I wanted back because I never would have paid them if I knew the house had major foundation problems.

Should I go to small claims court? It feels like I have a pretty cut and dry case with the screenshot of the email I was sent. I'm sure I could get something from the company they used to do the inspection too.
