Hi Ron - I always like these real world examples!
My 2c
Firstly, it would help if you could trim your expenses a bit - what, you eat cavier for breakfast, lunch and supper??
I also second selling your second house, for the same reasons, but you say the investment house is R620K, I am guessing the house you are in would go for a bit more? Taking a stab in the dark, lets say R800K. So all up you would have around R2,1mill to invest. So 7% would get you R12,250p/ and 6% R10500 - this of course is not including tax.
6% is nice and easy, guess around 50% REITS/ 50% Div Stocks: 7% and you probably going to be around 75% in property, but still doable. You cannot really buy ETF's for this - the dividends just are not there. Lot's of smaller REITS give excellent dividends so it becomes a bit of a balancing game - couple that I like and own, arrowhead, sacorp,TWR, TEX, Fairvest, Safari, accelerate - others are Rebosis, Delta. Decent dividend paying stocks (look at the special dividends as well) AVI, MMI, BTI,VOD, most financial/banks/insurance.
And of course, do not forget the overseas REITS and get yourself hedged!
Would only use TFSA for stocks and save 15%, use the REITS for your income cap (R73K) -
The nice thing about the dividend method is you do not really worry about what the value is (as you have no intention of selling) you just keep an eye on the dividends and make sure they are increasing - generally at around 10% , so you should have more to play with year to year. And you will never run out as you not selling the capital. It would make me mad having to decide when and how many shares I need to sell as well as watch my "stache" fall in a falling market. But each to his own, I am a bit of a worrier, so this method suites me down to a T. I do have a small account (under 10%) with my more speculative shares.
