Our (unconnected) neighbours are willing to exchange some of their land with some of ours to enable us to widen our drive. Both properties were purchased independently last year from the same vendor. The market value of the two pieces of land is, say £3K - who knows? I can't see any relieving provision for this type of transaction so SDLT will have to be paid by both parties on the value of the land exchanged (shame we didn't both negotiate slightly different boundaries when we purchased the houses). I'm hoping someone can confirm, or put me right if I'm wrong, that the rate of SDLT is fixed by the value of the land being exchanged and not linked to the original purchase costs of the two houses. SDLT manual confirms higher 3% rate does not apply.
