Im very late to the thread, but im very concerned about the threshold being £500k.
DH and I have a mortgage that runs into our 70s, mid 40s now. We both work really hard to keep up with our mortgage payments, which have vastly increased since our previous fix ended.
DH particularly, has a very stressful job. It is always in the back of my mind that he could have a crash at anytime due to the stress and we would need to sell the house. We do not have wealth. A house to house a family is £500k or more in many areas of the UK, well outside of London and the SE. We have very little equity.
Our retirement ages are after the age my dad developed dementia and before the mortgage is cleared and I cannot see us being able to do it until our late 60s.
It has always been our plan to downsize when the DC leave, but i don't know if they will. My DS1 (i was a young mum) is 27 and nowhere close to being able to house himself.
The welfare bill will certainly not be going down if the pressure on middle aged, middle earning people continues to ramp up. Occupational pensions are nothing like they were. Many people like us will end up having to sell, needing to rent again (having rented almost middle age) and claiming housing benefit to cover rent in retirement.
