I know a landlord in Thika Town who built one bedroom units on six floors, then on the ground floor, he merged three one bedroom units and modified them into a cozy place to stay with three bedrooms and a large living room area, he even has his own, for his own unit, standby generator.. the house is managed by an agent and not many people know he is the Landlord.. why build rental units then go rent elsewhere a place to stay?
