I am in an old building, 1 year after buying, we discovered fire safety is not done as well as well as termites. The contract says buyer cannot chase after seller for compensation. Going forward, I was thinking of amending the contract to "if anything is discovered within 3 years, of a problem that originated prior to the 3 years, then buyer can chase after compensation." My question is, Has anyone seen this type of term before? I want to know if it is outrageous or reasonable.
