That's exactly the point though - home equity isn't an asset unless you release it, yet it's a costing to you every year in tax, insurance, maintenance and upkeep. only a tiny fraction of people actually downsize for the purpose of releasing equity. It's incredibly rare. Also, no official measure of net worth includes a family home. e.g If you have a 3-bed semi, you'll likely spend 25-35 years paying for it (again, plus all the interest, tax, insurance, maintenance etc) and then be carried out of it in a box. That's not an asset YOU can use, but you leave it as an inheritance for someone else. For net worth, it needs to be an 'investable' asset, and your family home simply doesn't qualify in 95% of cases.
