Right now in the process of closing on a 2 family residence. Both units are oil heat, and after a decent inspection, I have a couple letters from the oil company (that the inspector was from), offering me a special deal on a one year furnace replacement free of charge on the existing equipment in one of the units if I sign an oil contract with them, and not extending the offer on the other side.
The amusing part, is that they mixed up the floors and the addresses that relate to the specific unit. The reason this is amusing is they have accidentally offered me this special deal on an original vintage coal furnace from the late 1920s that was converted to oil heat sometime in the 50s, and is coated with 3 inches of glorious asbestos.
They have specifically denied the offer for the other side, an early 90s oil furnace in great shape.
Im tempted to take them up on the offer, but I don't think there is anyway I can make it stand up once they figure out their blunder (since the inspector went on and on about it, amazing that the thing was functioning 70-80 years later). Yes, I would be very happy if they removed that monster that costs fortunes to run (that still has coal tools hanging around it amazingly) and modernized the house free of charge.
