What is (SDLT) Stamp Duty NI?

Currently, the tax is only payable on properties with a purchase price over £125,000 and over £300,000 if you are buying your first house in Northern Ireland. One clause for first time buyers is that if they buy their first property over £500,000 they will pay the same tax as a second home buyer.
