I'm going to move house and will rent for a while so I can look for somewhere in a new location. Given how dodgy the banks have been in the past, and not wanting to risk too much in shares that could plummet just as I need the money - what should I do with about £500K? I'd like to earn interest if possible but mostly I just want to know I can access the cash at fairly short notice when I do find a house, and I have given myself 3 - 24 months to look for the right place. I know about the 80K (ish) guarantee for each institution group, but wondered if anyone had any other creative ideas :) Not trying to avoid tax or anything dodgy I should point out, just want to take my time to find a suitable family home.
