Dear Jr. In a Purchase and Sale Agreement the term "as is" refers to the fact that the parties have agreed that the buyer will accept the property "as is, where is, what you see is what you get." Many times for whatever reason a property owner or bank prefers to price the property allowing for its condition, rather than full market value. Or, parties may negotiate to the "as is" position so that the buyer can pay a lower price.
From the seller's point of view, this does not relieve you of the duty to disclose., In fact, disclose everything for your protection as much as the buyers. Anything that you disclose to a buyer potentially insulates you from that buyer's successful lawsuit against you.
In most cases if you have disclosed a property condition the buyer would be unsuccessful in pursuing litigation against a seller after the fact. If you are aware of a property condition like a structural problem as you have indicated, you have two choices when it comes to selling residential real estate. 1. Bite the bullet, have the repair made and then sell your property at full market value. or 2. offer the property "as is" disclosing all property conditions, including the structural problem, and prepare to negotiate the price accordingly.
Best of luck to you in Monroe.
