Final answer:
In a 15 day contract, the owner can guarantee the resident a refund of any paid sums if possession of the residence cannot be provided on the agreed date. The contract will begin on the actual possession date if not canceled.
Step-by-step explanation:
In a 15 day contract, the owner can guarantee the resident a few things. Firstly, if the owner is unable to deliver possession of the residence on the agreed date due to various reasons, both the owner and the resident have the right to cancel the agreement and any sums paid will be refunded in full. Additionally, if the agreement is not canceled, it will be prorated and begin on the date of actual possession.
