Not at all suggesting that you don't move if you want to ... but if the price of propane is an issue, track it over several years compared to natural gas rather than just considering this winter. We've had propane since 1997. Some years gas is cheaper, other years it's higher.

And our propane company now lets us refill when we're down to 20%, instead of the 10% they used to require. Makes it much less likely that we'll run out when we don't have to cut it so close ... you might check yours, too.
