You can't be serious. 15 times annual wages - give me a break.
The national median house price is around $450 - $500K maybe even lower. The median wage is over $50K annually. We are propbably at 8 or 9 times income.
In the next 5 years we will likely see 15%+ growth in wages, maybe even 20%. A lot can happen in 5 years but my bet is we will see some moderate growth with house prices - particularly when interest rates start coming back down.
