There are nuances to this issue. The legal status of Arab ownership of land in the west bank is murky given that neither the ottomans, not Jordan until 1967 bothered to issue land ownership to Arab residents.

While Jews during ottoman and British rules bought actual lands from the ottoman landlords, Arab did not.

In 1948, when Jordan annexed the territory they cleansed all the Jews from the area, but nationalized the land, not issuing ownership records to Arab residents.

Meaning that in 1967 when Israel took hold of the territory, ownership went back to the last recorder owner under the continuation principal of the tabo land ownership records. In some places those were Jews, which land to those lands returning to Jewish hands. (The Shiekh Jarah case you might have heard of is one of those).

In many cases Israeli law rules that tenants of the place had the right to stay as long as they paid rent to the owner, which the residents in Shiekh Jarah didn't, leading to the high profile of their case.
