@IT'd - You should read, "How to get Rich - By Gerishon Kirima". Too bad it hasn't been published yet. As many people are telling you, don't let your earning power dictate how much you spend - especially recurrent expenditure. Higher earnings should be used to achieve your financial goals
faster.
I have a friend who works for the UN. I doubt any of his workmates live in the estate [Middle income] he lives in. But guess what. He is now a landlord - he owns a flat - three floors in addition to the house he lives in. He has numerous plots & other investments. His friends? Some have resulted to "hook up" with elderly expatriates to maintain their lifestyles!!! Who would you wanna be?
It's very difficult to down grade your lifestyle. Choose a simple [but comfortable] lifestyle now and fast track your investments. You can always upgrade if and when you want. My two Zim cents.
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
