My wife and I own a house in Chili (Churchville School District side). I never had to worry about sewer, so I guess that's covered in the taxes. In the fall and spring the town comes around and picks up leaves and debris if you pile it at the street...it's nice not to have to haul it to Basil. I've never asked, but I'm sure emergency responce is included...i saw that on an episode of My Name is Earl.
STAR saves you from paying School Tax on $30K of your home's value. Make sure you apply by March 1st.
We pay for water every three months and the bill is usually between $30 and $40. Its just the two of us and we use about 7K gallons a month. So $150/year is not far off.
We had many choices for garbage. WM, Suburban Disposal, Boone & Sons were the big ones I remember. I compared the offers and chose Waste Management for a two year contract. We get invoiced every three months and its about $90, so $30/month. It includes 1 Toter, 1 Bin, and up to six loose bags. We later paid $8 (1-time) for a second Bin. There are some special items that you need to call ahead for, but they will pick up most anything if you follow the rules.
RG&E is $140/month average (1900Sq/Ft, central air, gas heat, gas water heater). Other than that it's just optional stuff like Time Warner and Netflix. If you take care of your own lawn and snow removal then that's all I can think of.
I remember when we were looking/buying we got several worksheets and tools for calculating all these things from the Real Estate agency and the Bank. Make sure you ask them for anything they may have.
Hope this helps,
