We lease out tank from our supplier, because it was already set up that way by the previous owners. Tank lease is $85 a year. Current price is $2.28/gallon. That being said, we paid $2.65 when we bought the home last winter, and the tank was almost empty. the only thing the propane gets used for is cooking on the stove, as we use a pellet stove to heat the house. That being said, after talking with the propane company, they mentioned that the previous owners hadn't called for a fill in over 3 years.. So if my 250 gallon tank full lasts me 3 years, I'll be happy with that..
