I ended up attempting to trade forex and options but didn't work out as expected.

We had a Foreign National client who owned three properties free and cleat in tenn. 

They're a foreign company and not very easy to work with.

Of course that's a big IF here in CA since multi's have been absurdly bid up in price from foreign money inflows.

I am hoping a foreign real estate tax expert can help me on the top of foreign mortgage tax payoff gains, also known as section 988 of the tax code.I purchased an investment property in Canada in 2013, and financed the property with a Canadian mortgage.  

Meena Price , of-course consult with your attorney and CPA but if your LLC does business in PA, it will need to be registered as a foreign Corp in PA and pay PA taxes.I don't see the benefit of of have a LLC registered outside PA unless you believe the business laws are much friendlier, which is why some people choose states like DE.Some people deal in their personal names and carry an umbrella policy for liability.If you ever want to get a mortgage from a bank, most will not lend to LLCs.

The catch is both the buyers and seller is foreign national.

Law enforcement will confirm fraud as well as the bank but most likely it will be from some foreign country unknown  person

So, if you create an LLC in one of those other states, you will need to register it as a foreign LLC in California. 

A bit risky, but a lot of foreign money is sitting in that market right now with that anticipation!
