The Average Life Expectancy and Cost of Everything in Your Home

When you own a home sometimes things break.

And nobody wants to deal with a $4000 unexpected expense, scrambling to pay and putting the entire purchase on a credit card. Wouldn’t it be nice to have a general idea of how long your water heater might last and how much it will cost to replace?

Below is list of all of the major systems and components in the average home along with the life expectancy and installed cost.

Hopefully it will help you to plan out your home’s future maintenance costs. A good rule of thumb is to expect your home’s annual maintenance bill to be roughly 1-3% of your homes cost.
