I am told that an appraiser did an inspection in May and made no mention to the owner, which he is not obligated to, anyway. The crack, by all accounts, was unknown to the owner until this inspection. He is not selling, but has a warranty ready to expire. The grading does slope toward part of the foundation wall on the southwest side and there is erosion. This part of the landscape lays under a deck supported on concrete peirs (at least for now, since the erosion is washing the clay away from them, as well).
