Leviticus 27:14-15 - Redemption Of Vowed Houses
14 'And when a man sanctifieth his house, a holy thing to Jehovah, then hath the priest valued it, whether good or bad; as the priest doth value it so it standeth; 15 and if he who is sanctifying doth redeem his house, then he hath added a fifth of the money of thy valuation to it, and it hath become his.
