The problem of your math is that you are assuming rentals are equal from one place to another as long as the price match. I can tell you that's not true. My old 3BR apartment in a very desirable school neighborhood went from $2K to $5K now. My old neighbor still paying that price because their kids are in the school. They are kicking themselves right now for not buying when the rate was lower. Now, they are desperate to buy anything in the area.
