someone else's concerns when to buy house

With that approach, the ups and downs of the market will be someone else's concern.

This is a standard answer of "Realtors", "Brokers", "Builders" those who want to sell houses to you, your concerns are their concerns because without selling, how they make money, they don't care how much you pay, the higher the better they get, why should not they be concerned, forks, is it a mathematic question, you can get a house @ 450K why you pay 600K and keep it years. I am laughing .......they don't like you to maxmize your resources that minimize their gains, does it make sense?
