If you are full time here expect that your summer electric bill may be high. Mine gets up to $300 a month but I work at home all day and have a pool. I have clients who can keep it to $125 in the summer. The great news is most people don't even use the heat in the winter or when they do it is for a short period of time. Our utility companies will average your bill if you do not want the seasonal spikes.
As far as the water goes this is also determined by the home because of our on-going sewer project. If you buy a home on septic monthly costs are lower.
I have a FREE booklet I can mail to you called Energy Savers which will provide you some tips to saving energy and money at home. All I need is your name and address and I will get this right out to you.

I would estimate that an average electric bill to be approx. $ 200. Many homes do not have gas available and are all electric. If you heat your home, water, cooking and dryer with gas that runs about $ 50 per month but would be reflected in a lower electric bill average.
Hope that helps in your decision to move here. Lake Havasu is a wonderful place to live, blue sky, sparkling lake, surrounded by mountains and great people.
