I agree with Mydog .
It's not that I'm greedy, I'm not trying to con anyone into overpaying for my house. I'm fully aware of the COL thanks! I pay a mortgage and all the bills and my wage has not kept up with inflation.
BUT the situation for me is, I would like to move to a different area so I can afford more space. The next move will likely be very long-term so I want to get it right.
I've been in my current house over 16 years (it's my first home) the price I achieve doesn't really matter as much as the fact I need to be able to afford my next house and get all the deal-breaker things I need (off-street parking, quiet neighbour, nice garden etc etc).
These are all things I already have so I don't want to lose them and be paying a larger monthly mortgage, council tax bill, utilities etc.
If I can't both sell my current home and buy my next home for the right price for all the interested parties I can't move and that doesn't benefit anyone in the potential chain and although I'll be safe in my current home I won't be putting money into the economy in the same way (stamp duty to the public purse, EAs, surveyors, solicitors, movers etc getting paid).
I don't think the gov should interfere stamp duty holiday, Liz Truss etc etc and if I can't sell I can wait. However I have a pre-schooler and if they hit school age and settle well at school I might not want to move them for my dream of a more rural property.
So I may be stuck in my house another 16 years, nobodies fault, and definitely not mine because I'm being unrealistic. For all the chain to be created and complete everyone has to be motivated and want it to happen for the whole chain. That does seem a challenge at the moment.
