Leviticus 25:28-31

²⁸And if his hand have not found what sufficeth for him to restore it to him, then that which is sold shall remain in the hand of the purchaser, until the year of jubilee; and in the jubilee it shall go out, and he shall return unto his possession.

²⁹And if any one sell a dwelling-house in a walled city, then he shall have the right of redemption up to the end of the year of the sale thereof; for a full year shall he have the right of redemption.

³⁰But if it be not redeemed until a whole year is complete, then the house that is in the walled city shall be established for ever to him that bought it, throughout his generations: it shall not go out in the jubilee.

³¹But the houses in villages that have no wall round about them shall be reckoned as the fields of the country: they may be redeemed, and they shall go out in the jubilee.
