Leviticus 25:29-33

29“If a man sells a residence in a walled city, his right of redemption will last until a year has passed after its sale; his right of redemption will last a year.

30If it is not redeemed by the end of a full year, then the house in the walled city is permanently transferred to its purchaser throughout his generations. It is not to be released on the Jubilee.

31But houses in settlements that have no walls around them are to be classified as open fields. The right to redeem such houses stays in effect, and they are to be released at the Jubilee.

32“Concerning the Levitical cities, the Levites always have the right to redeem houses in the cities they possess.

33Whatever property one of the Levites can redeem  — a house sold in a city they possess — is to be released at the Jubilee, because the houses in the Levitical cities are their possession among the Israelites.
