Leviticus 25:28

25:28 If he has not prospered enough to refund a balance to him, then what he sold will belong to the one who bought it until the jubilee year, but it must revert in the jubilee and the original owner may return to his property.

Leviticus 25:30-31

25:30 If it is not redeemed before the full calendar year is ended, the house in the walled city will belong without reclaim to the one who bought it throughout his generations; it will not revert in the jubilee. 25:31 The houses of villages, however, which have no wall surrounding them must be considered as the field of the land; they will have the right of redemption and must revert in the jubilee.

Leviticus 25:33

25:33 Whatever someone among the Levites might redeem – the sale of a house which is his property in a city – must revert in the jubilee, because the houses of the cities of the Levites are their property in the midst of the Israelites.
