Moved house recently (ish) also and fixed in for 5 years. We're hanging on doing up the new house to see what happens, as a severe impact on interest rates means our savings go to that instead of home improvement.
But the builders have a good 3 to 6 month wait anyway it seems, so all will become clear in time.
A lot of people have invested heavily in homes and mortgages this past few months. As an example we bid on 9 houses in our search, 7 of which we lost out on, 5 of which were first time buyers offering no chain and jumping in a level above on the chain, where we wanted to be after over a decade in our first home. Family homes as opposed to first homes, if you like. But they were enabled to do that, by the banks and by the process. The bank wanted to offer us up to another £150k in mortgage borrowings, but I think you have to take a stand and show some reasoning. It's not free money, it's a level of debt most people will have around their necks for decades.
We know of one house near where we used to live that went for over half a million to a first time buyer. Now, if you have the income and the savings then fair play, but the sheer potential exposure and damage long term to your ability to live and have some comfort is frightening and we are not the kind of people to ever do that.
In fact the house we eventually got was put back on the market several weeks after the offer was accepted, as the bank refused to lend the original buyer that sum of money as he'd offered well above asking to secure it, and then had trouble proving his funding. There was a definite change in attitude from most banks between the start of the year too in how much they'd lend and to who.
We may be relatively slow and steady when spending our money compared to some, but I personally couldn't rest easy with such exposure.
