I would check with the firm that has this property listed, McNaughton Realtors. They may have a rental record for this. However, they may not, and if they don't, it probably doesn't matter. Utility usage depends on the renter/owner of the property. If the previous renter tried to keep the temperature at 65 degrees in the middle of the summer, the electric bill will be high. If they had their thermostat set at 75, then their bills will be much smaller. Utility bills depend on usage, and your usage may be completely different from the previous inhabitant's.
