Should be no big difference on the gas cost. Z* F9 W2 h6 p& lI 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.)
