I get a lot of questions via my blog in terms of how to find a house in Dar es Salaam, rent and procedures. I'm rather fortunate in this regard as accommodation is part of my contract and provided for. Hence, let me also underline, that I'm not the right person to ask in this matter.
However, to answer these questions, please read this article 'House Hunting Dar es Salaam Style', done by a friend of mine, and recently published in the South African Mail & Guardian here.
