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

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

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.

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

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. 

That return begins right away and takes little work to maintain, because a property manager takes care of the house for you.Provide diversification: Buying turn-key rentals in different markets of the country gives you diversification.Can be bought for cash: Many foreign investors have trouble buying properties, because they cannot get financing.

In this case, if you paid foreign taxes on the gain, foreign tax credits and/or tax treaties may come into play to avoid double taxation.Hope it helps

They believe I need a foreign LLC certificate here in Texas to set up the bank account.
