Your argument was that if owning would cost you the same as rent, then why not buy? Well, my argument to that was if you buy today when prices are steadily dropping rather than waiting a year (or more) that second year and thereafter, you’re gonna lose money. Period.
The argument is this. If we’re back to fundamentals, prices may continue dropping but only at the expense of rising interest rates. You can buy a house today for $500k, agree to pay $3000/month, and live in it for 20 years, and sell it for (let’s say)$1 mil. Alternatively, you can rent for two more years, buy the same house for $400k, end up paying the same $3000/month, live in it for 18 years, and sell it for $1 mil. Net result is the same.
And if you think that you may have to sell after a few years, you should not buy a house in the first place.
