My take:-for middle to upper class housing,then it could be a "bad investment"
But for low end housing,returns are good.
Example:-The same 15M will buy you a 33 by 66 around Embakassi for 5M then use 10M to do at least 4 floors of bedsitters 8 per floor.
Total units 32.Rental income 9000 per unit
Total 9000×32=288,000.
There is a possibility of doing 40 units(5 floors)hence Kes360,000 or even 48(6floors)hence Kes 432,000 though not advisable.Hizi ndio zina anguka.
So for me its low investment,high returns but of course high risk too.
Love is beautiful and so are those who share it.With Love, Marriage is an amazing event in ones life time, the foundation of joy, happiness and success.
