Hello, I am Keith, one of the experts on Just Answer, and pleased to be able to help you with your question.
The intention of the Stamp Duty Land tax (SDLT) surcharge was to deter people form owning more than one home. The transaction you are contemplating will expose you to the 3% SDLT surcharge. If you dispose of the duplicate residence within three years you can have the surcharge refunded by the Stamp Office.
I am so sorry to have to rain on your parade.
