If you are moving to the 65802 zip code, the City Utilities has an on-line access of bills for Realtors and Landlords. We enter the address and the date span we want to get a report for and it pops instantly. Ask your landlord to supply you with the report, if he/she hasn't done that, have him login to http://www.cityutilities.net/index.htm, choose tab 'business services', then 'Landlords/Realtors'. It takes 2 minutes for him to get access. I hope this helps.
Go to the utility company web site and see if it lets you look up the bill. Or just call their customer relations department. Being a full service realtor I have an agreement with my local city utilities that allows me to access their utility history. I'm able to advise my clients on the previous tenants utility bill. Most of my commercial clients have to have this information for their business plan!
# If you will be paying an electric bill, ask the electric company for billing on your unit for the past 12 months. The company must tell you. The same rule applies to natural gas pipeline utilities.
# Ask to see the landlord's "Energy Efficiency Disclosure Statement." He is required to post it in the building and to have you read and sign it before you rent. Get a copy of the form and more information about this law.
# Be sure that all utilities and appliances are working right. Make sure the landlord agrees to fix appliances, furnace and all other building systems.
If you are renting from a landlord, ask them for potential copies of previous bills. Some landlords actually have decent relationships with tenants or may keep the utilities in their name and have the deposit cover the previous month's utility payment. Sounds complicated, but there are some situations like this.
