What happens if the purchaser observes a defect after closing?

If the purchaser observes a defect after closing, unless it was actively hidden by the sellers, there isn’t much that the buyer’s lawyer can do to help. The buyer’s lawyer can send a letter to the seller’s lawyer asking for compensation, but the seller’s lawyer will likely respond with the Latin phrase “caveat emptor,” which translates to “let the buyer beware.” This is the general principle accepted by the courts, indicating that the onus is on the buyer to thoroughly examine the property before they complete the purchase, and if there are plainly visible issues that they did not address in the Agreement of Purchase and Sale, they are deemed to have accepted those issues.
