If you sold your house tomorrow, your wealth wouldn't change.
If I have £500k cash and a house worth £500k them my wealth is £1m.
If I have £1m house and no cash my wealth is still £1m.
If I have £1m cash and no house my wealth is still £1m.
Also if you sold your house tomorrow you'd have nowhere to live.
So presumably you won't sell your house, so the value of it isn't of much relevance to your life.
I disagree, as you may have guessed. The value of my house very much is relevant to my life should I ever, you know, want to get a loan or borrow against the equity from it.
And, yes, I would still have somewhere to live if I sold it, thanks anyway.
