Hire the home inspector (after the seller accepts the contract, as stated above) and have them check the place thoroughly. As far as the utilities go, some localities will turn the power and water on for a day to have the property inspected. Check with yours as it may be necessary for the inspector to schedule the time/day of the inspection.
Water is generally more important than electrical to have on during the inspection. Of course, for a property with a well, power is necessary as well to get water. On county/city property, sometimes the inspector will have the tool necessary to turn on the water at the meter themselves. Again, it depends on the local laws/customs.
