Leviticus 25:31

ובתי החצרים BUT THE HOUSES OF THE VILLAGES — Understand this as the Targum does: פצחין i. e. “houses of open cities” such as have no rampart. The term חצר occurs many times in this sense in the Book of Joshua, e.g., (Joshua 13:29) “the cities and the unwalled places thereof (וחצריהם)”; so also (Genesis 25:16) "by their unwalled places (בחצריהם) and by their strongholds” (see Rashi on that verse). על שדה הארץ יחשב [BUT THE HOUSES OF THE VILLAGES]… SHALL BE ACCOUNTED AS THE FIELDS OF THE COUNTRY — i. e. they shall be like the fields which may be redeemed until the Jubilee(not only in the first year) and go out in the Jubilee into the possession of their owners if they have not been redeemed in the meantime (Arakhin 33a). גאלה תהיה לו THEY MAY BE REDEEMED — at once if he (the vendor) so desires. In this respect it (the house in an unwalled city) has even a greater advantage than the fields, for the fields cannot be redeemed until two years have elapsed from the date of the sale (Arakhin 33a; cf. Rashi on v. 24). וביבל יצא AND THEY SHALL GO OUT IN THE JUBILEE — for nothing.

וּבָתֵּ֣י הַחֲצֵרִ֗ים אֲשֶׁ֨ר אֵין־לָהֶ֤ם חֹמָה֙ סָבִ֔יב עַל־שְׂדֵ֥ה הָאָ֖רֶץ יֵחָשֵׁ֑ב גְּאֻלָּה֙ תִּהְיֶה־לּ֔וֹ וּבַיֹּבֵ֖ל יֵצֵֽא׃

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