Leviticus 27:15-19

Yet if the one who consecrates it should want to redeem his house, then he shall add a fifth of your assessment price to it, so that it may be his.

‘Again, if someone consecrates to the Lord part of the field of his own property, then your assessment shall be proportionate to the seed needed for it: a homer of barley seed at fifty shekels of silver.

If he consecrates his field as of the year of jubilee, according to your assessment it shall stand.

If he consecrates his field after the jubilee, however, then the priest shall calculate the price for him proportionate to the years that are left until the year of jubilee; and it shall be deducted from your assessment.

If the one who consecrates it should ever want to redeem the field, then he shall add a fifth of your assessment price to it, so that it may belong to him.
