Thank you for your question
My name is Clare
I shall do my best to help you but I need some further informtaion first
Does your wife wish to come her permanently?
Why are you concerned that she will not get a visa if she purchases a property?
Your Wife is able to own property in the Uk without any restrictions - it will be Registered in her name without problem.
If she does experience problems coming to the Uk then she can instruct agents to deal with the property management.
I am not sure of this deals with all your concerns - please ask if you need further details
