None of this sounds like it's an insurmountable problem. Once again the ultra-liberal agenda is proving detrimental to our nation's security.
It's not a question of security and you're arbitrarily, or worse yet on purpose, ignoring that politics is about relationships. Would you stamp on Putin's foot when you go into a meeting with him? Would you punch his daughter, would you arbitrarily repossess his legally held property? Why would you upset and act like a petty child over something that doesn't effect national security in the slightest.
You do know Russia has an embassy in England, as does North Korea.

So they can maintain an embassy, which encompasses multiple buildings, a military advisor office, what about 50 diplomats, hundreds of staff(many of whom will be spies, just like many of our staff in Russia will be also).... but having a personal home is compromising national security somehow?
Putin probably owns buildings in America and the UK/USA(in terms of government owned buildings used for the current political leaders) almost certainly own places in Russia as well.
The very idea we should deny them the ability to buy a house is basically childish and it's exactly the opposite of how this country should behave in regards to potential enemies. Diplomatic relationships prevent wars more often than they start them, and cutting them off by building resentment between the UK and a superpower.... thank **** you aren't in politics.
UK/USA are amongst the most uncooperative nations around, who block things like the UN trying to stop Israel being ****'s. They also ignore the UN when they want to start illegal wars for monetary gains. UK/USA foreign policy has continued to be the most aggressive and detrimental of anyone else around.
