You haven't mentioned if you currently reside in the UK as many lenders will only deal with residents of the UK. Having said that there are some that will help ex-pats etc but this is where you really need to see an IFA who can use their specialist knowledge.
to be honest there is no one answer to who is the best lender as the follow up questions will often lead to a different lender for a dozen people with the same initial requirements.
