You could actually put the house in both your names as tenants-in-common, then if you die first, your half can be left to whoever you wish- a charity perhaps. It won’t be his.
There are various implications in doing so, which you should read up on and speak to a solicitor.
Have you considered if you should need care in the future? How will you fund it? Owning another property will complicate that.
Find out about capital gains tax, inheritance tax, deprivation of assets, as well. Best to be fully informed, not just react emotionally.
In my opinion, for what it’s worth, the house should have been sold and the money split. An end to the hassle.
If he stays, your brother should be paying you rent on your half. Who is going to pay maintenance costs? Insurance, repairs? There is a lot to think about and I feel you need some objective advice before you make a big decision about the house. Your brother is manipulating and bullying.
