I love this guys daily blog... always worth the time reading as he takes a national perspective on everything from politics, to impact of policies, to oil, to investment markets, and to housing. Usually pretty darn spot on and has been for over 10 years I've followed him.

As for the question about buying or renting? It ALWAYS comes down to the math of your particular situation. There is always an opportunity cost associated with using your cash to buy a house (ie lost investment in the markets, versus a single volatile commodity), versus renting where you want (ie commute time, personal time, close to amenities, etc...).
If you want some great housing deals just wait another 18-24 months IMO... by then everyone that bought big homes out in the sticks since they can WFH will be called back to the work place. By then they'll be sick of their 2xdaily 45+min drive (and associated costs), not to mention rising interest rates making them even more house poor.
