What are the rates like for this scenario?

Hi BP Members, 

For any type of loan at amount over 1M, are the rates higher if the borrower is foreign national for security reasons? and If a foreign national puts a high down-payment for a house in a fast-appreciating market, would these facts lead to or can be negotiated to a more favorable rate? and finally if anyone know the range of the rates for this scenario?
