To say that they are things that no one wants is merely speculation. 

I bought a speculation biotech penny stock a while back that had what I thought was a good product.

In addition, at least in my business model, I don't have to speculate and leave my investment up to others, with flipping RE, I control the market and investment by controlling my acquisition price relative to actual value and control the market by getting in and out within 3 to 4 months which drastically reduces potential for devaluation over time.I can not do that with gold investments and I can not live inside of gold either.

This is a far superior strategy than speculatively trying to guess where market tops and bottoms are.In the same way, you should start with smaller deals to get a greater understanding of the business and build organically.  

That is more speculating and given where the Miami market is right now vs the height of the market back in 2007.... 

You are not investing, you are speculating.  

So there is a very limited pool of homes under $200,000 which keeps pushing the prices up.When you talk about huge population booms I think speculation.

Looking at appreciation in a short time span is too speculative for my taste.

Ali,I strongly agree with your suppositions, and I'll add a few of my own.

There are speculators and there are Investors in every market.Jeff
