Leviticus 27:14-15 - Redemption Of Vowed Houses
14 And when a man shall dedicate his house to be holy unto the LORD, then the priest shall value it, whether it be good or bad: as the priest shall value it, so shall it stand. 15 And if he that dedicates it will redeem his house, then he shall add the fifth part of the money of your valuation unto it, and it shall be his.
