Protection belongs in the same budget. If the mortgage depends on two incomes, it depends on both people staying well enough to earn. That is the part of the purchase we advise on directly.

Wales has no first time buyer relief, so Land Transaction Tax applies at the normal rates. Homes up to £225,000 pay none.
