Owning your own home

Currently I give away more than a third of my salary on rent, which isn't something I want to do forever, or even a moment longer than I have to.

Just FYI, interest payments = rent. It is just that your landlord is different, in one case it is the bank, in the other a regular landlord.

Those payments you make OVER AND ABOVE INTEREST (called principal repayments) are simply a choice you make about saving.

You could just as easily rent for 20 years or whatever and save in an ISA every year and the savings would allow you to buy a house outright whereupon you don't have to pay rent OR INTEREST.

Instead you are taking a MASSIVE bet on the property market.
Not that there is anything wrong with that but don't kid yourself that somehow owning a house makes you a better saver.

Greed is when people have 2+ houses and rent 1+ out.

The irony of that coming from someone who is, with his girlfriend, is renting 2 properties!!
Who would you rent from if people couldn't own more than one property??
