If everyone who currently owns gets plunged into negative equity or looses what they have paid in they won’t move will they?
IME many people don't understand there's a price you can't sell under unless really forced to.
Took 10 + pre kids to save deposit - house prices went down after we bought but that didn't bother us as we could afford the bills.
When eldest got close to secondary school age and DH was working away all week paying rent and train fares back to us - we decided would be worth moving despite house price being less than we bought it for.
We worked out to buy in new area needed same amount of deposit as bought first house with and we could borrow slightly more- we had saving to cover the moving costs.
So we were essentially writing of the 20K of work structural/improvement work the structural survey hadn’t picked up needed doing and 7 years of a repayment mortgage and ending up in place we’d started in with same amount for deposit on next house.
I got accused on her and in RL of price gouging and being THE PROBLEM and as long as we weren’t in negative equality of course we could move.
No amount of pointing out we needed a house in new area or would be better off staying put and paying our current bills got through.
Selling below that price we'd have essentially been stepping off housing ladder probably for good given our ages and us and the kids would be back to the insecurity of renting long term and rents weren't cheaper than our mortage repayments.
The first house few years after we move regained the "price" so could have waited it out though moving when we did was best time for eldest schooling.
Long term slumps or slow downs of housing market would be in everyone interests - I'd like my kids to have chance to buy at some point -and the monthly rents at minute seem insane but crashes I think may people just can't grasp what it means.
