The majority of homes up here are heated with oil. Could that be a coincidence? More likely all these thrifty Yankees have found oil to be lower cost than propane in rural areas. So I don't think that propane would, on average, be a selling point here.
And oil does not go Kaboom. A few times a year we hear of an entire house blowing apart due to propane.

I would not spend a single night in such a house ever. I'll stick to safe activities like riding the Harley.
