No, it really isn’t. From your link:
“If someone were to rent you home today, how much do you think it would rent for monthly[...]”
That’s a very poor proxy for housing cost.
First of all it’s a guess. A guess from whom? What do these oracles know about how much their home can rent for if they haven’t put it up?
Second, the homes available in the rental market are vastly inferior from (for example) my home. I cannot find a home remotely as nice as my home (bought in 2017 for 320k, currently valued for 400k - pretty average middle class home in my city) but I can’t rent mine for what I’d want to rent it for [1] - so the supply and demand price don’t overlap for my type of home in my city. Without overlap of price, the question, as it pertains to my home is meaningless.
On the other hand, there is an easy way to include housing price for owners. Add price of homes to the CPI. In fact, investments generally should be included, since they are goods whose price raise with the increase in monetary mass
[1] is the accelerated deterioration of my home, and the headache of being a landlord worth the $1400/month renting it to a family? No.
Can I rent it for $1800 by splitting it into rooms, say, for students? $1800/month is not worth having destructive students live here.
