> I pulled up Zillow Rentals around downtown and there's a comical number of listings available.
And how does that tell you that supply exceeds demand?
Even when there's a housing undersupply, units will still be available at any given moment. It's not like people stop dying, moving out or building altogether.
To determine oversupply, you need to look at something that also tells you demand as well. Like, what's the average time available units are on the market? What's the vacancy rate look like?
