On the issue of increasing in rent. I think most landlords will. I had a stall in tao and it happened to me when gova introduce vat on commercial properties. The landlord just past the vat on our rents. So you either take it or leave.
Look at Nyayo Highrise Embakasi. The rents were at 25-27 the other day for 3 bed flat. Because of the new road, they have gone up to 28-30. You can argue that this is marginal. What a landlord will do is to increase rent marginally say by 3-5K to maybe 32K. He then works out his costs such that whatever he pays has a minimal impact on him.
Again demand and supply comes into play here. For one tenant rent of 32K may be high so he moves out. For another, that is the kind of rent he would be comfortable with.
Where I leave, my friends are prepared to pay 5 to 10k more. So they keep telling me to get them a house in my estate. Infact my landlord really wishes I move out as he knows he will get higher rent.
LONG TERM effect is that if there is LITTLE investment in this sector because of ROI, demand will be so high that rents will sky rocket. How may of us can afford to buy houses? It is really a catch twenty twenty and the victim might end up being you and me.
