Hi and welcome to JA. I am Ray and will be the expert helping you today.
Here your lawyer would send demand letters for the cost to repair and remediate the property.Alternatively you could sue here to set aside the sale.
This is a shotgun deal you go after the seller, the inspector, and the realtor.You also can file complaints against realtor and first inspector for professional negligence here--failure to disclose.
California overall is a full disclosure state.They would hold all of these folks liable.You would likely get offers from the realtor and the inspector because they have errors and omissions coverage.The seller here may have had homeowners
coverage too this may come into play.
You are more likely to get some serious damage money here than setting aside the sale.Your lawyer will likely get a forensic accountant or other professional to estimate what it costs to bring the house up to the condition it should be at sale as well as ancillary costs like rent for you if you have to move out for a period.
Your lawyer will also seek legal fees and costs as well and this is all added up here.
You need a real estate
litigation lawyer, you can get one here.
File complaint against realtor here.
You have recourse here through the courts to recover your losses and possibly to set aside the sale.
I am so sorry that you are having to go through all of this.
I appreciate the chance to help you today.
