I am purchasing a short sale home, did a home inspection, and removed home inspection contingency. Based on some of the exchanges I had with the seller, i am concerned that there might be a damage to the house or missing appliances,etc . I would like to add an addendum stating that COE to take place only after buyer verifies and approves the condition of the house after seller vacates. The seller agreed. If I find things that are not satisfactory, can I cancel the contract because I don't approve the condition of the house according to the addendum?
