So I'm looking to hire a structural engineer to assess the foundation and give me me a quote if it needs repair. 

If what you say is true I'd:A) Hire a lawyer who will likely get a notarized letter from the inspector stating there was no damage as well as scare the heck out of the realtor and potential buyerB) Report the buyer's realtor here: http://www.dre.ca.gov/Consumers/FileComplaint.htmlIf you want to back out of the contract I'd speak with the lawyer first.

So far the damage includes the air conditioner, brand new refrigerator, brand new stove, brand new microwave and several ceiling fans.

@Joe Splitrock I will have to remember to hire you if I ever need to coax a tenant out!

RIP) and while the contractor for the Home Warranty company is saying it needs to be replaced the tenant is pissed because it's been 4-5 days without air conditioning. 

Steve, you should also have Hired and Non-owned Auto and strongly consider EPLI and Cyber.

I completely gutted and remodeled the kitchen and bathroom, refinished the hardwood floors, added central air all while living in the property.

This will probably require creating an LLC and obtaining a IRS employer identification number. 

It's a sense that because the city has hired someone to fix things like that, it's ok to break it.

Try looking into house hacking a multifamily property like a duplex, triplex, or quadplex with the intent of doing Air bnb.
