Why Know the Age of Your House?

Whether you are a professional, real estate agent, or a house owner, calculating the accurate age of the house is very important & helps in certain official works. These include insurance for both the house and the owner.

Also, knowing the age of the house helps in understanding why owners preferred certain designs to adore their houses over time. Still today, older houses have less energy-efficient systems like HVAC, insulation, and appliances running. And house age lets you plan how you can renovate it according to the remaining age.

The age of house can affect its selling costs. Every other buyer tends to purchase a newly built property and that is why, increasing the age of the house decreases its market value over time.

What Is the Average Lifespan of a House?

On average, the age of a house is between 50 to 100 years. This lifespan is not the same for every other property. It depends on the construction material. With that, the weather conditions also affect the life of the house.

Houses that are in areas with extreme weather conditions have comparatively shorter lifespans as compared to those in areas with stable environments.

Average Life of Different Construction Materials:

Material Expected Life Span
Cement and Bricks Structure 75-100 years
Stone Structure 150-200 Years
Concrete Structure 50-60 Years
Wooden Structure 100-150 Years
