ויקרא, פרק כ״ז, פסוק ט״ו

When an individual dedicates personal property to the Temple treasury, a unique legal and financial framework governs the process of reclaiming it. The original owner, along with his wife and heirs [מלבי״ם, אדרת אליהו, פירושי רד צ הופמן], retains a special right to buy the property back. This process is specifically defined as a redemption, as the property returns to its original source. By contrast, if an unrelated person were to acquire the property from the Temple, it would merely be a standard purchase [ביאור יש״ר].

Reclaiming a consecrated house requires the owner to pay its assessed value along with an additional penalty of one-fifth. This surcharge accounts for human nature; people naturally tend to undervalue their own assets when trying to buy them back. To protect the Temple treasury from financial loss, this extra payment is mandated [בכור שור]. The calculation is done inclusively, meaning the added amount is a quarter of the principal, ensuring that the surcharge constitutes exactly one-fifth of the total final payment [פרדס יוסף]. This added fifth carries strict sanctity of its own. If a person improperly benefits from this specific surcharge, they commit a trespass against the Temple and must pay yet another fifth on top of it [תורה תמימה].

The obligation to pay the added fifth applies strictly to the original owner redeeming the originally consecrated item. If a person transfers the sanctity from the first object to a second one, and then redeems that second item, the surcharge does not apply [תורה תמימה, רש ר הירש, העמק דבר, אדרת אליהו]. Similarly, if someone designates an offering for a friend's atonement, the friend may redeem it without the extra penalty, since he was not the one who consecrated it [תורה תמימה]. A creditor who redeems the property to collect an outstanding debt is also exempt from the additional charge [העמק דבר].

The redemption transaction must be executed with cash or movable goods of equivalent value, entirely excluding payments made through land, slaves, promissory notes, or rental fees [רלב״ג, מלבי״ם, צפנת פענח]. Furthermore, ownership only reverts to the redeemer once the funds are physically in the hands of the Temple treasurers. Standard methods of finalizing a transaction, such as physically drawing an object toward oneself, are ineffective here [רלב״ג, אדרת אליהו, צפנת פענח]. Consequently, if the property's market value rises before the payment is finalized, the owner must pay the new, higher price [תורה תמימה].

The immediate practical reality of consecrating a house is eviction. While a consecrated animal might temporarily remain in its owner's barn, a house must be vacated immediately upon dedication. Only after the redemption funds are fully paid may the owner return to live there [העמק דבר]. Once redeemed or purchased from the Temple, the property dynamics differ from standard real estate. A house bought from the Temple treasury does not remain with the buyer forever, as it reverts to the original owner during the Jubilee year [תורה תמימה]. Additionally, unlike a regular house sold in a walled city, which becomes permanently unredeemable if not bought back within a year, a consecrated house maintains its redemption status indefinitely, allowing the original owner to reclaim it at any time [רלב״ג, פירושי רד צ הופמן].
