Zillow: ‘Hidden costs’ of homeownership can add $15k yearly

What are the hidden costs of homeownership?

Between mortgage payments, homeowners insurance and general maintenance, the costs of homeownership can add up quickly. In fact, according to a recent analysis by Zillow, hidden homeownership costs can be as high as $20,000 a year in some metropolitan cities. Zillow calculated its totals based on "three unavoidable expenses for single-family homeowners — property taxes, homeowners insurance and utility payments."

Of these three unavoidable expenses, there's one you can chip away at over time — utility bills. Savings from energy efficiency improvements around your house can add up quickly, and there are a few simple things you can do right now to make a big difference.

Easy energy efficiency upgrades

• Upgrade to a smart thermostat: Installing a smart thermostat can be an easy way to lower your heating and cooling bills with minimal effort. These devices can automatically adjust the temperature in your home to optimize your heating and cooling while lowering energy costs. According to Energy Star, most smart thermostats "learn your temperature preferences and establish a schedule that automatically adjusts to energy-saving temperatures when you are asleep or away."
• Replace old home appliances: Older appliances are often less energy-efficient than modern models. You can always buy an energy usage monitor for around $30 to see how much energy your appliances consume. Alternatively, the Department of Energy has a free online energy usage calculator to help you find your home's biggest energy hogs.
• Use energy-efficient lightbulbs: Energy Star-certified LED lightbulbs often require up to 80-90% less energy than a standard lightbulb. Those with smart capabilities can be set up with routines that shut them off automatically if you forget.
• Seal your windows and doors: Windows and doors may be worth replacing if they are relatively old. Still, newer windows and doors can be sealed with foam insulation and caulked to help your home retain warm or cold air.
