Should be no big difference on the gas cost.& T% f) w+ H- p8 s+ ~
I like the split level very much because less stairs to climb. It's perfect for seniors and kids.

No big difference but 4-level split should have less cu ft of space, a little bit less of fee is expected provided that there is no other variables (like insulation R-value etc.)
