I am from the UK but have spent around half my time in Botswana where I have a house.
Because Botswana is to xenophobic I decided to leave and hopefull not return there.
I had done voluntary work in Kenya with the Maasai in 2012 and find Kenya far superior to SADC countries.
That said I have had my problems dealing with potential property sellers the police and border officials but nothing compared to Zambia and Tanzania both of which are simple scum bag, corrupt countries. I hope never to revisit them too!
