Is it the same (or connected) vendor?
If yes, then these would be linked transactions and so SDLT at 3%.

"Fair" in your opinion - we will never know. Unless there was a decent break between transcations (not just exchange of contracts and completion but also negoatitions - this hasn't happened) it is difficult to see how these wouldn't be linked. The law is drafted wider than HMRC 's interpretation of it and even based on the latter these would be linked.
