I'd think long and hard before buying a house with friends. If you buy this year, you may be in negative equity for a couple more years, who knows. What if one party needs to move house (eg. to move to Australia, or buy a house with a partner, lost their job). What would happen then? It is a VERY BIG commitment to enter into such a huge financial commitment with friends. It changes the happy-go-lucky arrangement you have now, to one of being very committed to each other financially. So much so that any plans one person may have in the next few years, seriously affects the lives of the other two in the agreement.
