I'm so glad I got a lifetime tracker now; just no-nonsense, I've had it for a decade, no need to renew it (complete with additional fees every 2, 3 or 5 years) and it turns out that even when rates go up it's still better value than the fixed deals people are getting "just to be safe".
Granted abetter play would have been to perhaps get a 15 year fix last year IF I were planning to stay in my current place, but I'm not, I'm hoping to move in the next year or two. It's all a bit moot tbh.. current mortgage is like < 30% LTV, prices could fall a fair bit or rates could go up more and it's going to have limited impact.
In fact if prices do fall a little bit I guess it eats away a bit at some of my equity but it should hopefully mean the future (more expensive) home purchase is cheaper which is still better overall - I guess the main risk is regional variations, the sorts of places I would like to move to increased a bit during covid when my area/property type (apartment in London) stayed pretty stagnant, I'd hope those areas will fall a bit more and mine a bit less but obvs mine could fall more I guess and that would be bad relatively if the desirable areas just outside London maintained their prices.
