I mean, you could buy a 3 bed / 1.5 bath house in the bay area for around $200k in 2000. 5x is roughly correct, easily.
Two examples: 3bd house in the Chicago suburbs, sold for $190,000 in 1999, and $420,000 in 2021. 5bd house in the Houston suburbs, sold for $290,000 in 2003, and $480,000 in 2022. If there were 5x price growth, these houses should be selling for $1m-$1.5m.
