Real Estate Law
Have Real Estate Law Questions? Ask a Real Estate Lawyer.
If it is something that an inspector should reasonably have caught, then the inspector can be sued for missing it. If it is something that the previous homeowner knew was there, but didn't tell anyone about, then the previous homeowner can be held responsible.
Not against the previous homeowner. But if you got an inspector, then potentially against the inspector.
I would suggest hiring a local real estate attorney who can help you seek any potential claims you might have.
