i don't know what type of houses ya'll are building but as an example i backed out the cost of the lot on this house and it came to $113 per foot. as you can see it's a nice house with 10' ceilings through out except 12' in the living room. tray ceilings, 11' walk through shower, double garage, back patio with fireplace, and outdoor kitchen with grill, sink, and fridge. and that includes the sod, landscaping, fencing and appliances.
