Will,
I tend to lock in all my mortgages on fixed rates, so not so concerned in short term. Mind you, it never seems to be the actual rate that counts, just the expectation of future moves which determines how the mortgage companies set up their fixed rates. Not sure how they do this technically, but I've been reading that the insiders in the city have priced in low interest rates now for the next few years, and if banks follow these so-called specialists, I think we'll be alright for a time.
Floating repayment rates is one risk I take out of the equation!
