Final answer:
Usually, the seller is responsible for maintaining the property's condition until closing. They would typically need to repair a broken garage door opener or compensate the buyer. This should be verified with the sales contract and local laws.
Step-by-step explanation:
The question concerns who is responsible for repairing and paying for a broken garage door opener on a property in Dover one week before the closing date. Typically, the seller is responsible for maintaining the property in the condition it was in when the offer was accepted until the final closing. If the garage door opener breaks during this period, the seller would generally be required to fix it or provide some form of compensation to the buyer. This may be stipulated in the purchase agreement and can also vary by local laws or customary practice. It's essential for both parties to refer back to their sales contract and consult with their real estate agents or attorneys to determine the specific terms outlined regarding such eventualities.
