Fact of the matter is that if you were borrowing 200k over 25 years at 2% you would have been paying 850 a month
With interest rates at 6%, paying 850 a month you can only borrow 132k
So that buyer has lost 68k of their purchasing power, and every buyer needing a mortgage will be in the exact same position
The buyer won't be able to magic up that extra money so it will have to come off the price if the seller wants to sell
Obviously the only person that loses out in these examples are people downsizing
