Any recommended real estate attorney who has working knowledge of structures to put in place for foreigners investing in RE ?

In your post, you say the LLC is owned by an Australian Family Trust (foreign trust), but that you, individually are the member of the LLC?

Online foreign sites only or elsewhere?

Generally speaking, owning a property in another state is usually considered to be "operating" in that state and requires registering your LLC with that state as a "foreign" business entity.

We are in Dallas-Fort Worth and Indianapolis and work with a lot of foreign investors.

Look at the Foreign money moving into the Pacific NW and the effects of Chinese Monetary policy.

However, I will say that LLC is not recognized in Canada and deemed a foreign corporation, resulting in unfavorable tax treatment.  

or register the AL to the PA LLC, for which I will need to pay foreign LLC fees.I understand the benefit of having separate LLCs for each property, but I am wondering which option will be cheaper in terms of fees in the long run? 

In particular would be great to connect with others in the Miami/FL community as well as people with experience in foreign investing (I have interest in South America for long term value creation).  

I believe a lot of it is from foreign investors looking for appreciation.
