Matthew Henry on Leviticus 27:14-25
Here is the law concerning real estates dedicated to the service of God by a singular vow.
I. Suppose a man, in his zeal for the honour of God, should sanctify his house to God (Lev 27:14), the house must be valued by the priest, and the money got by the sale of it was to be converted to the use of the sanctuary, which by degrees came to be greatly enriched with dedicated things, Kg1 15:15. But, if the owner be inclined to redeem it himself, he must not have it so cheap as another, but must add a fifth part to the price, for he should have considered before he had vowed it, Lev 27:15.

John Gill on Leviticus 27:23
Then the priest shall reckon unto him the worth of thy estimation, even unto the year of jubilee,.... The priest was to estimate the field of purchase sanctified, and set a price upon it according to the best of his judgment, and give it to the person that sanctified it, or whoever would redeem it; and this estimate was made, according to the number of years there were to the year of jubilee:
and he shall give thine estimation in that day; the price set upon the field by the priest immediately, either the sanctifier, but without adding the fifth part, as in Leviticus 27:19; so Maimonides (g) observes, or any other purchaser:
as a holy thing unto the Lord; to sacred uses, as the repairs of…
