Not saying there's an endless supply of these, but they are out there.

Phoenix is a very job diverse market, massive population growth, the standard of living is relatively low (aside from real estate), there is a major supply shortage of "starter" homes and costs are high to build new homes which all create higher property and rent prices.

With crazy prices, no-contingency all cash offers, and a serious lack of supply I was ready to chalk it up as a loss and give up on real estate.

Supply MUST far outweigh demand in order for prices to fall. 

With decreased manufacturing supply costs are likely up and holding costs are virtually certain to increase.   

Trying to calculate supply/demand of a market & looking for a reliable resource helping me determine the current number of multifamily units in a particular city? 

As of right now, housing prices have stayed pretty steady in the Southern California market due to the high demand and limited supply available.

Walking through Lowe's or Home Depot and pricing out supplies can be helpful as well.  

I think that the basic principal of supply and demand will prevail both off and on market. 

When the US reopens the demand will come back but all the supply will be gone.
