Oof, yeah how do you plan for the future of propane prices though. I sold 6ac to my buddy who built next door to me. He also didn't want to pay to tap into the natural gas line at the road and run it 600' back to his house. Despite my pleas, he went propane also, due to the low upfront costs (free tank, only need a basic furnace, etc). 2 years later after spending THOUSANDS on propane refills and getting jerked around by the delivery company, he had to take out a home equity loan to get a woodstove (foolish, sure, but) and now they try to never use the furnace. That low upfront cost of propane actually turned out to be pretty expensive. Of course they still have to use it for water heating and the oven, and look out the window at a big ugly tank sitting there.
I'll say it here one more time before I shut up (haha), but a modest solar PV array can easily cover the consumption of a set of very-affordable mini-splits, especially if you supplement with wood heat. With solar payback times under 10 years for almost every location now, then you're looking at decades of free heat and free electricity.
