Hi Waqar,
Re mortgages - UK banks tend not to lend on overseas properties, buy may have a foreign subsidiary that would. Another option would be to remortgage you UK home to free up any equity or raise a deposit by extending your UK mortgage and then take a foreign currency mortgage for the balance.
It's probably best to speak to a specialist mortgage broker first - London & Country Mortgages at lcplc.co.uk or Charcoal at charcoal.co.uk Best to ensure your broker is on the FSA register on fsa.gov.uk
