Hi Lakeowner. You had an attorney represent you at the closing, right? I would go back and ask the attorney to review the case, then file a suit against the seller if what you're saying is correct. Was there a contract? Was there a survey? Was there title insurance? Was there an inspection performed? This is why buyers and sellers need the services of not only a REALTOR, but also a lawyer.
If you didn't use an attorney, then for sure you need one now.
