If you're on iOS you will not be able to add a property to your Trov. This feature is currently only available to customers on Android.
On Android, once you're in the Trov app, click “Property” from the (+) menu to add your home. If you’re at home, allow Trōv to see your location, and your address will pop up on the screen. Click on it and press “Add” in order to have your home, its market value and a description added to your Trōv. You can also manually enter your address in the search bar.
