I know this can't work but hear me out

My sister and I will inherit a 4 bed detached house on the edge of a village. Will go on the market for approx £400k.
The close that the house is in is occupied by 8 other houses. All lived there for 30 plus years.
This is a hypothetical situation currently but I want to sell it for £200k (approx) with caveats about not reselling in a certain amount of time, allowing a young family to move in to a house they couldn't thus afford. I may sound a complete twat- my sister and I would love the money but £100k each would change our lives immensely plus another family's life. What haven't I thought of? Am I a complete knobhead?

No idea of the legal stuff but what about shared ownership? SOmeone can buy your sister's half for £200 000 but you retain your half.

You cannot change “the system” and society by doing this. Many people are frankly not nice and a large proportion are simply entirely self serving at best. Your feel good feeling would rapidly evaporate and you would just feel taken advantage of which I’m sorry you undoubtedly will be.
You would be better off selling at market value and helping your own children with their futures, not some fantasy in need family. You could if you choose donate to some nice small local charities who would be able to use the money to genuinely help those in need. Gently too you could pay for some counselling for yourself after carrying such sadness and distress for three decades. It’s never too late to have counselling. Go easy on yourself - you can’t fix the ills of the world and need to focus on you and your own family, it’s absolutely okay to do that.

This is the biggest pile of shite I’ve read on mumsnet.

You’re in a position where you are renting right now and you will be in a position where you will inherit give or take £200k…
Why on god’s almighty earth are you not considering buying your own property once this has sold?
Renting is dead money and when you pass on, surely you’d want to leave something for your DC?
Depending on what part of the country you live, you could buy a decent sized property with possible cash left over or put down a significant deposit on a property so that you’ll have a smaller mortgage.

Apolos if mentioned already, HMRC will still regard the house as worth £400K even if you sell it for £1, so there may be significant inheritance tax implications that you need to be cognisant of before you make any decision.

I have thought about this OP - if we ever sell and move abroad (somewhere cheaper) we wouldn't need ALL the money.
Sadly, the sort of people who would benefit from this are the least likely to pay it forward. Just look at the number of people who buy their council houses via RTB and promptly upgrade selling it off to landlords or renting it out for a huge whack. I'm not blaming them - I might do the same in their position but when money is involved sadly people would rather have more of it than help someone else.

You're better off selling it slightly lower than market value - maybe 50K off, instead of 50%.

I cannot understand why anyone with 4 children , living in rented accommodation would be willing to ‘gift’ someone that they don’t know and have no connection to £100k . Think of your own children @CrazyBatIknow and put the money away for their futures .

This won't work, as everyone has lamented, but one major issue with selling massively under value, is it affects the value of all the houses on that street. As it will be presumed they are all worth £200k if yours sold for that. So your neighbours might not be happy if they look to sell up in a few years.

Or of course, the new buyers would sell and double their money. You can't put any restrictions on a place you no longer own.

The only way you could do this is renting at reduced cost as once someone owns the property that’s it. I also don’t understand why you don’t want to use this money for your own children futures instead of someone else’s?
