As others have noted, it is included in inflation measures here.
But on your point about price appreciation being a negative factor not positive, I'm with you. I am not helped by my house being "worth more", it just raises my cost in taxes and insurance and makes my city shittier when the people who work here can't live here because they are priced out.
I talk with the husband about this - we bought our house at what I thought was the peak of some bubble, thought we overpaid. But not even 5 years later it would sell for twice that, so he thinks we got a good deal. I'm valuing the utility of housing as shelter, it can't be "worth" more than 30% of two average monthly net-pay for someone working here, right? By that measure we overpaid, can only barely afford it with two good incomes (us) plus two part time incomes (our teenage kids) He's valuing it like an investment and by that measure we got a good deal, we bought something for x and now it's worth 2x.
