My claim about ‘not losing much’ was more that many sellers would have had the property since before 2019 so in some sense they could feel like they didn’t lose anything if they just forget the 30% rise since 2019. But I guess you’re right about many not wanting to lose long mortgage terms at low rates (this does feel like a US-specific thing though hard to change in the short term as mortgages would have been priced based on the current rules)
