Great discussion thus far!
I work in PE real estate and the recent noise in the equity markets, drop in commodities, the China story, and any other reason people can think of has added a lot of frothiness to investing in commercial real estate. For example, REITs are trading at a discount to NAV while core assets are trading at all-time highs. All kinds of mixed signals but the REIT market is a proxy for the private market so let's see what happens.
With that said, you have to look at the fundamentals related to RE investing (i.e. job growth, affordability, unemployment, historical pricing, etc). All the indicators appear to be healthy at a national level but you really have to focus on your particular market as they are all different. In some markets, the affordability factor has gotten way out of hand. This is especially true in the Bay Area to the point where folks are moving to lower cost of living cities, with Portland being a hot destination as Google, Facebook, and other good employers have setup base there. Another example is Houston, as their economy is heavily weighted to the energy sector, with gas prices being so low companies have started to lay off employees so there is no job growth or wage growth in addition to less demand for RE via people purchasing or renting. This has depressed RE in that market as supply / demand equalize.
But my overall take on the Bay Area is that it reached/will reach its peak soon. It is hard to predict when, otherwise I would be very rich. But what I think will happen is that a lot of these tech companies will stop getting funding as the VCs and public markets begin to tighten their belts with all this turmoil happening in the markets. In addition, a lot of companies have over hired based on competition for talent, growth plans, and investor expectation. I think people will begin to wake up to what is actually happening vs. what they think will happen. Investors in Snapchat have taken a write-down on the value, Twitter and Yahoo are laying off people, and Uber is actually losing money. These are big headlines but have done nothing. These headlines will only pickup with turmoil in the markets. Not saying it’s a dooms day as Apple, FB, Google are probably not going anywhere based on how much cash they have and the strength of their business, but the smaller tech firms that never had a chance anyways, that hired a lot of people and paid them well, will be wiped out in the coming years. All this will create less demand for RE via less renters, less people able to qualify for financing, etc. and present good opportunity for investors. Just my take. I apologize if I was all over the place but quickly wanted to get this out as I am at work :)
