I have a R182 and it costs about 150/hr if I fly 150 hrs/yr. So I fly more, my overall costs go up but my hourly drops.

2000/yr insurance
2500 annual with minor fixes
I own my own hanger but still I have to pay 60/mo for electric and taxes.
I figure it costs me about 25k/yr to own and fly 225 hrs/yr, at least I hope it does.
If you figure in the cost of the money, which most people neglect to do, a fixed gear 182 of 1980 vintage was broken down to 200/hr in Private Pilot Mag flying 150hr/yr.
I would say that unless you NEED to fly for business, renting is much cheaper.
If you score a good deal on a plane it usually ends up costing more on the back end also. There really is no cheap way to own.
I live 2 miles from the airport so it makes it worthwhile for me, I suppose you have to sit down and be honest with what your mission needs to be.
Flying is more important to me than a big house, so getting a plane was an easier decision.
You only live once, you might as well enjoy life, just don't get in over your head and end up in too much debt.
