Leviticus 27:17-19

New Century Version

¹⁷ If the person gives a field at the year of Jubilee, its value will stay at what the priest has decided. ¹⁸ But if the person gives the field after the Jubilee, the priest must decide the exact price by counting the number of years to the next year of Jubilee. Then he will subtract that number from its value. ¹⁹ If the person who gave the field wants to buy it back, one-fifth must be added to that price, and the field will belong to the first owner again.
