1. Verify the account and rate context
Use a current bill supplied through an authorized transaction channel. Confirm the service address, billing period, utility, rate classification, meter count, and whether the account uses a standard, time-of-use, net-metering, or another approved schedule. NV Energy says the rate classification appears at the top of the bill and that optional services use different rate types.
Do not request login credentials or take control of another person's utility account. If a classification or charge is unclear, ask the utility or a qualified energy professional—not the real-estate agent—to explain it.
2. Ask for a full seasonal pattern
One summer bill can exaggerate a normal year; one mild-month bill can hide peak cooling use. When the seller is willing and the transaction permits it, request a 12-month history or a month-by-month summary. Record kilowatt-hours or other usage separately from dollars because rates, fees, credits, taxes, and billing structures can change.
NV Energy says enrolled MyAccount users can inspect use down to 15-minute intervals. That level of detail may help the account holder understand peaks, but it is still their private account data. The buyer needs only the information authorized and necessary for the property decision.
3. Match use to the house and the household
Inventory the facts that can move consumption: square footage, orientation, glazing, insulation evidence, HVAC age and service history, thermostat behavior, water heating, pool equipment, irrigation controls, electric appliances, vehicle charging, occupancy, work-from-home hours, and solar or battery agreements.
The U.S. Department of Energy says Home Energy Score can provide comparable information about a home's energy use, where available. Its FAQ also says the score does not include utility bills or resident behavior. Use the score, prior bills, inspection, equipment records, and your own intended use as different evidence—not interchangeable answers.
4. Build a range and list the unknowns
Do not convert the seller's average into a buyer promise. Create a low, planning, and stress case using current rate information and documented use assumptions. Label unresolved items such as equipment condition, solar transfer, pool schedule, future rate classification, or planned occupancy as pending or unavailable. Route technical, contractual, utility, financing, insurance, tax, and legal questions to the responsible professional.
Example: the low bill came with a different routine
A buyer sees a low recent electric bill and assumes the home is inexpensive to cool. The file later shows that the seller traveled often, used a different thermostat schedule, had no electric vehicle, and participated in an optional rate plan. The correct response is not to call the bill misleading. The buyer records the differences, verifies current service and equipment facts, and builds a budget for the buyer's intended use.
FAQ
Is the seller required to guarantee my future utility cost?
No. A prior bill documents the prior account and period. Your cost can differ because of rates, weather, occupancy, equipment, behavior, and service choices.
Is a Home Energy Score the same as a utility history?
No. DOE says the score does not include utility bills or resident behavior. It is a separate standardized assessment and may not be available in every area.
Should I ask for the seller's utility password?
No. Use consent-based documents or summaries shared through an appropriate channel. Never request or retain another person's account credentials.
