The Israel Land Administration, which administers 93% of the land in Israel (including the land owned by the Jewish National Fund), refuses to lease land to non-Jewish foreign nationals, who include Palestinian residents of Jerusalem who have identity cards but are not citizens of Israel. When ILA land is "bought" in Israel it is actually leased to the "owner" for a period of 49 years. According to article 19 of the ILA lease, foreign nationals are excluded from leasing ILA land, and in practice foreigners may just show that they qualify as Jewish under the Law of Return.
