a) Fixing for the longest affordable term, rather than the cheaper 1 or 2 year year deals
I think issue is many people who bought their first house in the last 10 years have never known interest rates of more than 1.5% till now. The headlines I read on 'mortgage shocks' etc seem rather odd, as for anyone whos had a mortgage before the mad period of 1.5% products knows the 'normal' is 5-6-7% products.
Infact even now I think lending is 'cheap' compared to inflation, I've secured another lot of additional borrowing at 4.5% incase our build project needs the funds. 4.5% is still over 2% cheaper than my first mortgage in 2008.
