I think it is rare for a foreigner to get bank financing in Mexico.

I know foreigner mortgage is a little hard but i am doing my research in that area already.

If the funds are still outside the US in a foreign bank you might get some push back since the money has not been through anti-money laundering processes yet and the banks don't want to get tied to selling REO to bad people.

Hi James,I have several contacts with foreign investors who are pulling together their resources to get Scruggs, some from England, Canada and Australia.

As a foreign investor, I can only get 50-60% down, 2/1 ARM 4% mortgage from the lender finances my first purchase.

Quick question though, Is it possible to operate a wholesaling business in the U.S. from a foreign country?

Foreign member of an LLC will still have this tax withheld before profits are distributed from the LLC.  

We are getting ready to list our property for sale in Grand Junction, Colorado and owner financing seems like a foreign idea to our realtor.

You need to Foreign File the existing LLC in every state you wish to do business.
