Does that account for increased housing prices? It probably doesn't, because housing prices (cash price, per the fed) more than doubled since 2005: https://fred.stlouisfed.org/series/NYSTHPI
If you did a 30 second search, you'd see it's factored into the CPI, with "Shelter" (which further breaks down into rent and owners' equivalent rent) making up 36% of the CPI basket.

Unless owners are completely in the loop in terms of the rental market (which they likely are not, they don't rent), they may not come up with good estimates for what an equivalent rent would be.
