Selling a home within a walled city operates under entirely different rules than standard land transactions. If the original owner or his relatives fail to redeem the property within a year, ownership transfers absolutely and permanently to the buyer. This one-year countdown begins exactly on the day of the initial transaction, remaining unchanged even if the first buyer resells the property to someone else during that time.
The timeframe granted for redemption is an exact, complete year, calculated strictly from day to day without missing a single twenty-four-hour period. In the event of a leap year, commentators differ on how this duration is measured. The primary approach among commentators is that the calculation includes the added leap month, thereby granting the seller extra time to reclaim his home. Conversely, [רבי יהודה הנשיא] maintains that the timeframe strictly follows a solar year of exactly 365 days, independent of the lunar calendar. Once this precise year expires, the property is entirely removed from the seller's control and stands definitively in the possession of the buyer.
The law extends beyond standard residential homes to encompass all structural elements within the city, including olive presses, bathhouses, cisterns, trenches, and caves. However, opinions diverge regarding unbuilt plots of land. While [רבי מאיר] suggests the rule also applies to rocky fields used for gathering building stones, the accepted view of [רבי יהודה] dictates that open fields are not classified as houses and are therefore excluded from this regulation.
The definition of a walled city relies on historical status rather than present reality. The law applies to a city even if its walls have fallen, provided it was enclosed by a wall in the past, specifically dating back to when the Israelites entered the land under Joshua. Furthermore, the physical relationship between the house and the wall is crucial. Because the legal focus remains strictly on the structure itself, [רבי יהודה] derives that the city wall must encompass the house from the outside. Consequently, a home built directly into the city wall does not qualify under these specific laws.
The transfer of ownership after the first year is absolute, a principle that applies equally whether the house was sold or given as a gift. The property remains with the recipient and his heirs forever. This requirement of generational inheritance excludes property dedicated to the Temple, which cannot be permanently retained in this manner because the Temple has no heirs. Similarly, these rules do not apply to homes in Jerusalem. Since Jerusalem was never formally divided among the tribes, no private individual can claim absolute ownership over property there.
Because the transfer of a walled-city home becomes permanent after a year, it naturally does not return to its original owner during the Jubilee year, unlike regular land. The specific consideration of the Jubilee addresses a unique scenario: if the Jubilee year occurs during the first year of the sale. In this case, the arrival of the Jubilee does not cancel the transaction or automatically revert the property. Instead, the seller retains the right to redeem the home until the full year concludes; if he fails to do so, the sale becomes final. Ultimately, the laws governing walled cities are inextricably linked to the Jubilee, applying only during historical periods when the broader Jubilee regulations are actively observed.
