Economics matter: Market trends and supply and demand. 

I believe if people make money and there is sufficient housing supply, housing will become affordable. 

I'd be more worried about supplies to build houses (eg wood for the framing). 

He seemed very authentic in our discussion and showed charts indicating how the cost of supplies has increased more over the last 2 years than they did over the last 20 years.  

Lots of new supply now with reduced demand.

Because of this the supply is relatively low which means the ones that do exist tend to make good money, especially if you theme it toward bachelor/bachelorette parties.

There are always deals out there and Texas is experiencing a return to normal with pricing coming down and supply staying up.

Pay for supplies upfront.4.

You'll definitely get the long term appreciation in the San Diego market since our supply levels remain low which helps to insulate our market here, but it will be hard to cash flow on immediately unless you use one of the above strategies I mentioned. 

If there are barriers that limit similar supply and you figure out how to get the housing units online, even better.
