Beware the Doctrine of Merger

This doctrine states that, upon closing, the agreement and the parties’ rights therein are “merged” in the deed. This means that after closing, the parties can no longer rely any warranties or representations of the original contract.

Make sure that your Offer expressly states that a warranty or a representation will survive the closing, otherwise this doctrine can preclude you from doing anything when a promise is not fulfilled or a representation is false.
