In my experience in the Tampa market it is very hard to find a new construction in a new development neighborhood that will cash flow positively after a CDD, HOA, higher RE Taxes and then all the other expenses associated with owning an income producing property.

If the property does not produce a "positive cash flow" then you should pass.Cash flow is what you have left after paying mortgage, taxes, insurance, and other expenses.

As an aside, I have focused my landscaping on food producing plants. 

In most cases the long term strategy will produce a better return but thats not always the case.

You also need to produce and maintain good documentation surrounding the financial accounts and investment holdings of the LLC. 

If you do need to go back and get traditional financing, it may be more attractive to a lender if the property is already producing income.

I have a c-Corp in CA with income producing rental assets of $1M free and clear.

One of my main questions is since the building isn’t producing any income and technically isn’t worth anything, how do you go about offering for this type of properties?

Unfortunately for Qatar, there is a huge amount of shale gas in North America that can be produced at de facto no cost since it's the byproduct off shale oil production.

Regarding price - the question for you is what price do you need in order to produce the return you want?
