No way is it, especially with the lack of mobility. Do your research and build up a picture of the cities opinion, as i do. I am leaving my huge loan on a tracker for a good while yet for a reason.
The problem with that is as VonHelmet says, if interest rates do run away with themselves and your stuck on a tracker that tracks at 2.5 above base, if rates get to 5%, your paying 7.5% whereas fixed would only be 4.99 or similar.
I think rates will go up but not by much - inflation is a big issue right now but its partly artificial - VAT, QE etc. It might tail off the end of the year.
If you truly want to know month in month out what you are going to pay then fixed may be for you. Also if your not a natural saver and likely to spend the difference rather than overpay then again fixed might be the right choice - peace of mind as it were.
Best to get as much information as possible and make up your own mind.
