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 27:24
In the year of jubilee, the field shall return unto him of whom it was bought,.... Not to him that sanctified it, whether he redeemed it or not; nor to him that bought it of the treasurer of the temple after it was sanctified; but to the original proprietor and owner of it, of whom he bought it that sanctified it, for so it follows:
even to him to whom the possession of the land did belong; which was a possession of his he had by inheritance from his fathers, and therefore, according to the law of the year of jubilee, was then to return to him, and could be retained no longer, nor even converted to holy uses; for as it is said in the Misnah (h),"a field of purchase goes not out to the pries…
