Made my first million at the age of 19, while still in university in UK. I used to paint peoples houses on my own (at half the cost of local painters), as i got more houses to paint I got other uni students to work for me, and soon i was painting around 5 houses a week. Within two years I saved up around 20,000 pounds and used it as down payment to buy a small rundown 2 bedroom house(my family really helped me at this time in getting the mortgage and giving me confidence). I renovated the house and within 4 months sold it at a 30% profit. After that i kept buying and selling property till i finished my course and headed back to Kenya.
Came back home with enough money to buy a plot of land and build a block of apartments and got into the property developing business.
