Yeah if you are staying in the same home and area long term then short term price changes aren't going to get you to sell unless someone offers so far above market rates that it's impossible to say no.

Yeah primary residence property as an asset should help fund retirement by downsizing and having as many great experiences as possible when healthy or paying for care if needed or supporting and being around family.

And for assets as big physically as a house you can't really buy if you need to sell for the same price in the short term
