That's a good question but not able to answer it correctly. For the past 15 years the house was used as a studio for film makers. No one lived in the house 24 hours a day, but there was a lot of electronics going on, so what they paid would not be what a normal family would pay.
I can share my information which may be similar except I have a pool which uses electricity all day.
My electricity with 2 adults, the pool, 2 refrigerators, electric cooking and electric clothes drying my bill runs about $250 for 2 months. Water runs about $125 for 2 months. Gas runs about $25 a month.
If you want to see the house please call me on my cell phone 310-717-6114, Thank you for asking about 4404 Westlawn.
