Should I relocate to Cape Town?

Hi I am an Aussie Am able to obtain a visa for 4yrs and extend it if desired. My questions are as from what read when over there and now back in Perth is that if I come in on retirement visa its 4yrs so am asking what would cost of living be include Per month: Talking about reasonable living standards Rent Electric/power Fuel insurance and so on Also have stayed in Milnerton proper mostly and that area seems reasonable. Now like Big Bay area, cost seems lot more As a Builder in Australia plan to by and renovate a house to fill in my spare time and also doing this helps to meet others. Is it worth renovating? What do most think about Milnerton Proper? Other areas that I should look at?

What places  should go to meet others, capetownies and expats One thing last time was over there most speak English (whites) but unlike here they start talking Afrikaans as if to leave you out of conversation. Am I expected to learn Afrikaans? In Australia we find it rude to talk to say Italian to leave others out. There is lots I still havent seen although I have been there a few timeS and lived with a family in Cape town and due to what just mentioned I had a disagreement :-(

This all means selling a lot here to move and plan to buy when arrive Also before I buy a house would have to rent. What would this cost? and where should I rent, should I share rent with a couple others ? Thank you in advance for your input
