I am a mortgage advisor here in Dubai, and I am sure that the type of information needed to give you an idea of mortgages available doesn't need to include personal information such as your names, address, dates of birth, etc. Try not to pass any of this information online - they don't need this info, but want it, so that they can contact you about mortgage, loan, credit cards, etc. Let me know if you want to discuss your options - I would be more than happy to meet you in person.
