Raising finance for overseas property

Here in ireland banks can do a credit check to see any other loans you have right?
So - If i go to AIB they can see if I have a current mortgage/loan outstanding with say,BoI yes?

Can banks find out if you have any mortgages/loans outside of the country they operate in?

I work for a finance company - and yes we have access to MOST of the loan / mortgage / credit card / store card details along with payment history / defaults and CCJs etc through Equifax.

Yes, banks can check internationally but mostly they dont bother checking since it costs them money to do so.

For those of you investing in Budapest - they are preapproving foreigners for mortgages on new builds now, well - usually it is done through the bank that is financing the development.

I don't fully understand what that guy did.

Basically - did he not disclose all his borrowings when applying for mortgages ya?

The reason is i am wondering that if i had just received a mortgage in one country and was highly geared in that country would this reduce my chances of geting a mortgage in another country?
Could it be interpreted that there is added risk in the portfolio as a whole and therefore reduce my chances of getting a mortgage in another country?
Or would the 2nd country just look at the mortgage application as a stand alone mortgage application (In which case they wouldn't care about other borrowings)?

If it's the former then I would withold information about other borrowings in other countries if i thought i could get away with it.
