I found it odd that so many guys have missed your analogy on occupation and replacement value. (Don't worry this is is part of a global problem that actually got Trump into office and will keep him there for 2 terms. A majority of the world's population loves screaming headlines and wont read beyond the first paragraph. Call it the "Twitter effect".)
As the article says, YES, DAR ES SALAAM has a higher real estate value than NAIROBI. But first this wasn't a ranking, 2nd it is explained in the lower paragraphs that private investment in real estate (Which nairobi has more of) is desired over government investment (TZ government entities are involved in most of the projects) therefore making Nairobi more attractive than Dar es Salaam.
This by the way is a reporters perspective of the world bank report, who has actually partly failed by making it a Nairobi - Dar affair which from the report it is not. Read the report further and come up with your own perspective, prompt even better arguments on what we may need to do to to make the situation better. Otherwise we are all just trolls on the internet.
Sadly what we have here is basically a shouting match between two very uninformed camps.
