Why should someone in London have to sell their deceased parents family home to pay iht, whereas not in the north?
Carrier Pigeon my heart bleeds, but I am struggling to imagine why you are still living with your parents as a late middle aged adult. Shurely time to move on and make your own way in the world, as a striver etc.
Another solution would be some rather more drastic measures to bring down London property prices - thus removing the problem. I'm a big fan of rent control myself. Last time it was tried in the UK, house prices came tumbling down, and housebuilding and home ownership spread across the UK, ironically creating the bedrock of home-owning conservativism we have all come to love.
Of course this is now extremely difficult in the UK because 40 years on from the sale of council housing, we now have an economy in which peoples' sense of success and prosperity is indissoluably linked to the perceived value of their home - well done Margaret.
This fine tradition has been carried on, as I mentioned higher up this thread, across all political parties, with 40% of all MPs now Buy to Let landlords. So if you stop and think about it for a moment beyond, say, your own front door, we are all in a bit of a pickle, basically - although you and your immediate family will be ok - at least for now - obviously - so that's all right.
I'm guessing you have never lived in a gated community, with its own private police force. I have. I hope your children and grand children enjoy it.
