Just to put this in perspective...
foreigners are buying in London in droves given the perceived safety. They have also had beneficial tax treatment. That is being tightened up but our tax laws are being driven with a far more political agenda than I've ever seen. If an overseas national buys a property at a hefty discount then that's asking for trouble.
Doesn't matter what the solicitor says, HMRC now havr I think 20yrs to come after you if they think you're being fraudulent.
