Mortgage for overseas property (Brussels)

HI everyone,

Does anyone have experience with taking a mortgage to finance an overseas property located in Poland?

I got a feedback from ING that Poland is not on the list of authorized countries and therefore they will not be able to help me. It's related to their internal procedures.
Today I'm expecting to speak to BNP rep. ...

Which banks are the strongest players in Belgium in terms of mortgage financing?

Thanks in advance!
