There are a lot of factors that can sway the range of these utilities bills. Age of the home, pool, number of people living in the home, type of insulation, type of windows, etc.
But to give you a rough estimate my house is 4100 sqft with a pool and I pay:
-gas $40-$200 mo
-electricity $180 to $600 mo. -water $150 to $300 mo (I live on a 1/3 acre with a pool and lots of grass and trees etc)
-trash $45 a quarter
Hope this is helpful.
