You probably need another correction: CPI does not count the cost of a mortgage, nor interest payments in any direct way.

What the CPI estimates is the price of shelter, by surveying renters how much rent they pay, and house owners how much rent they think their house would rent for.

It's a bit frustrating that there are so many misunderstandings around this topic, while the BLS has clear and extensive explanations on their website.

it's more that people have an innate desire to own (their residence). When they see prices of houses grow, they feel disenfranchised. They blame it on inflation - because to them, the house hasn't changed when its price grew.
