Instructions
Walk up to the wooden sign posted in front of any house that you own. Press the "A" button.
Look at the details that appear on the screen. If the house is currently occupied, you will see the amount of rent the tenants are paying, as well as an "Evict tenant" option.
Highlight "Evict tenant" and press "A." The people living in the house are immediately removed. You can now use this house as a place to sleep, have a party or raise your family.
Interact with the sign in front of the house if you decide to rent it out again. Set a rent price and select "Rent out" to instantly gain a new tenant.
