When Safety Inspector Prentice suspects an abandoned oil tank while showing a rural bungalow, what should the buyer require?

When Safety Inspector Prentice suspects an abandoned oil tank while showing a rural bungalow, the buyer should require that the seller remove the tank before closing and show compliance with environmental standards. This is the correct course of action because abandoned oil tanks can pose environmental risks, including leaks that can contaminate the soil and groundwater. By insisting that the seller removes the tank before closing and provides evidence of compliance with environmental standards, the buyer ensures that any potential hazards are properly addressed before taking ownership of the property. This proactive approach protects the buyer from inheriting any environmental liabilities associated with the abandoned oil tank.
