@migi. this will help. http://a4architect.com/2...oject-for-rent-at-thika/ Return on Investment is the same, around 7 years if your units are designed with viability in consideration. Ensure you dont mix the2 due to social conflict. 2 bdr renters usually hava families while 1 bdr renters are single hence social clash.

@migi..welcome. Since return on investment is the same for all, my advice is just stick with all 2 bdm or mix only 1bdm and bedsitter units for the whole block.

My opinion. Not professional. I will go for 1 bedroom, targeting single occupants. Singles pop is increasing as many young people are not keen on marriages any more.

@Migi, heed a4arc, and welcome to my neighborhood around slaughter house near the water tanks opp Ashut. here is My experience: 1. Single units are in high demand but the costs associated with their management is an issue to consider before embarking on brick and mortar. One such cost is septic exhausting and water management. Compare this a flat with say 50 units will fetch you 8000 per unit per month on the higher side. The cost of such a building will be over 40 million. Cost of management could be about 50k per month. Compare with: 2. Two bedroom self contained units on a similar sized plot will fetch you about 20 units each generating 15,000 per unit per month. Will cost less than 30 million to build and monthly expenses may not exceed 30k. I have 2 bedroom units and don't envy my neighbours with their many singles.
