Leviticus 25:29

27 he shall calculate the years since its sale, repay the balance to the man to whom he sold it, and return to his property.

28 But if he cannot obtain enough to repay him, what he sold will remain in possession of the buyer until the Year of Jubilee. In the Jubilee, however, it is to be released, so that he may return to his property.

If a man sells a house in a walled city, he retains his right of redemption until a full year after its sale; during that year it may be redeemed.

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

31 But houses in villages with no walls around them are to be considered as open fields. They may be redeemed, and they shall be released in the Jubilee.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
