As for the cities of the Levites, the Levites always have the right to redeem their houses in the cities they possess.

Leviticus 25:31
But houses in villages with no walls around them are to be considered as open fields. They may be redeemed, and they shall be released in the Jubilee.

Leviticus 25:33
So whatever belongs to the Levites may be redeemed--a house sold in a city they possess--and must be released in the Jubilee, because the houses in the cities of the Levites are their possession among the Israelites.

Numbers 35:1
Again the LORD spoke to Moses on the plains of Moab by the Jordan across from Jericho:

Numbers 35:8
The cities that you apportion from the territory of the Israelites should be given to the Levites in proportion to the inheritance of each tribe: more from a larger tribe and less from a smaller one."

Joshua 21:2
at Shiloh in the land of Canaan and said to them, "The LORD commanded through Moses that we be given cities in which to live, together with pasturelands for our livestock."

Ezekiel 48:14
They must not sell or exchange any of it, and they must not transfer this best part of the land, for it is holy to the LORD.

Notwithstanding the cities of the Levites, and the houses of the cities of their possession, may the Levites redeem at any time.
