Leviticus 25:29

And if a man sell a dwelling house in a walled city
Which was so from the days of Joshua the son of Nun, as Jarchi:

then he may redeem it within a whole year after it is sold:
any time within the year he pleased, either he or any near of kin to him; and if they would, on the day it was sold, or any time after within the compass of the year, even on the day in which the year ended; in this such an house differed from fields, which could not be redeemed under two years, (See Gill on Leviticus 25:15);

[within] a full year may he redeem it;
from the time it was sold, paying what it was sold for: this is to be understood, Maimonides ^F8 says, of a solar year, which consists of three hundred sixty five days, and within this space of time such an house might be redeemed.
