Leviticus 27:13-15

New Century Version

¹³ If the person wants to buy back the animal, an additional one-fifth must be added to the price.

Value of a House

¹⁴ “‘If a person gives a house as holy to the Lord, the priest must decide its value, according to whether the house is good or bad; as the priest decides, that is the price for the house. ¹⁵ But if the person who gives the house wants to buy it back, an additional one-fifth must be added to the price. Then the house will belong to that person again.
