Leviticus 25:29-34 - Release Of Houses
29 And if a man sells a dwelling-house in a walled city, then he may redeem it within a whole year after it is sold. For a full year he shall have the right of redemption. 30 And if it be not redeemed within the space of a full year, then the house that is in the walled city shall be made sure in perpetuity to him who bought it, throughout his generations. It shall not go out in the jubilee. 31 But the houses of the villages which have no wall round about them shall be reckoned with the fields of the country. They may be redeemed, and they shall go out in the jubilee.
32 Nevertheless the cities of the Levites, the houses of the cities of their possession, the Levites may redeem at any time. 33 And if a man purchases from the Levites, then the house that was sold, and the city of his possession, shall go out in the jubilee. For the houses of the cities of the Levites are their possession among the sons of Israel. 34 But the field of the suburbs of their cities may not be sold, for it is their perpetual possession.
