Its not all land in Kajiado that has been X-marked for nullification, your agent should better be knowing areas that have disputes, other than that, the real deals are getting better by the day.
The land problem in kajiado emanated from within, A guy with huge chunks of land passes on, the children are not of age yet, relatives take over and sell off the land, when the kids come of age they demand the land back. basically that is it.
the warmer the blankets, the colder the future
