A good starting point will be to pair with a with nationwide lender (if not all cash), check in with @Joseph Chiofalo for financing without a US credit score. 

I assume this allow them to come to closing with less cash down. 

Currently, I find myself in a situation where a significant sum of my cash is held up due to complications between these entities.
