I probably should know this myself but anyway...
An estate is being/has been valued for IHT purposes (hadn't occurred to me how quickly it becomes due). However, if subsequent house sale was for a different value is IHT then adjusted accordingly?
ie house valued at £1,000,000 now and then sells for £2,000,000 - IHT is initially due on the £1M but the remaining would become due once house sold?
Thanks
