Where I am, an adjustment in asking prices is what's needed - that's the change I need to see. The differential between what a house was bought for in the last few years and recent asking price is easily 20%, so not wishing neg eq one jot - still plenty of room to make a bit without having to lose anything, and mostly looking at downsizers who haven't sold for 30 years and places needing major re-furbs on top of top market price being asked. These people don't need to sell for now, likely.
Plenty of reductions coming on now - 10%+, even after just a few weeks marketing, so there is hope. There is a limit to how far the market can rise - a limit to the proportion of the population who can afford to buy a 3-bed semi for £400k, or a small 4-bed det for £500k+. It just needs to stop rising.
A crash will need specific factors, but a number of these may well be out of our control, although Gov doing best to prop up the market at current level.
Is depressing to think that our children will face more competition and expense for an education which may or may not result in a decent-paying job just to hopefully one day (in their early forties?) afford a two bed terrace they will be working 25 years to pay for, and their student debts...........
Those that don't need to sell won't, but there will always be a proportion who do need to sell and the market will be established by those sales.
