Owning your own home

Exactly - long-term.

So everyone who thinks that they can borrow 110% live in it, paint the walls magnolia and sell it a year later for 30% more than they paid can eat shit and die.

I bought a one bed flat in Bermondsey about 3 mins walk from the tube nine months before the extension was completed in 1999. Bought it for £63K and sold it for £95K less than a year later. That helped a great deal :)
