Yes. A tennis court can add value to your home if you are able to use it frequently for recreational or competitive play. However, if the court sits empty most of the time and isn't used, it will likely have a negative impact on the value of your home.

It depends on your area and the other homes that are for sale in your area. A tennis court can be a huge selling point if there are few of them in the area, but it could also be a turnoff if there are many. In my market, it would likely add value because it is rare and people who love tennis would love to live in a house with one already installed. But, as I said, this varies depending on where you live. Talk to a local real estate agent to get an idea of what kind of impact having a tennis court would have on the value of your home.
