MashaAllah, may Allah make it easy for you.Alright so first of all congratulations. I am also planning to move to the North of Somalia to start a business in the near future. I am tired of the West.
What you said about the problems in real estate in Somalia is spot on. You essentially have to be there to be safe and fraud is also rife and add that to the undeveloped legal system which is unsurprisingly built on "ninka aad garanaysid"
Your investment application idea sounds good but what we really need is a property management company that is headquartered somewhere in Somalia to manage the various assets of Somalis abroad who do not have the time to deal with qashin and politics. The East and South Asian diaspora has done the same thing successfully.
It is true that this happens, however it is much less common than it was before & much more difficult for someone to do now. On the plus side, when you look at the percentage of people who have bought land and had nothing happen to their asset, and you compare that to people who have had their land stolen from them--the overwhelming majority of people have been safe with their purchases Alhamdulillah. Nonetheless, evil people do exist and you could end up having your land stolen from you if you are not careful lol.
Property management would be a good idea if it were to assume responsibility for your land in the future if it becomes disputed. However, knowing the situation on the ground--no private business would have the power to do so. They would primarily be responsible for maintenance & finding you a tenant (someone paying rent if you built a house), however anything past that would be impossible.
