This sounds very dispassionate, so I’ll say first neither of my parents are in good health and my sister and I love each other very much and get on brilliantly.
My sister and I will inherit our parents property. It’s 3 bedrooms but small, needs significant upgrading but is in a good area with great schools, a few yards from the beach and has a big garden with off road space. It’s probably worth £120k as is. My sisters kids who are 12 and 6 years older than mine are either well on the property ladder or ready to move abroad. When my parents pass I would like to buy my sister out and sell the house to my son. I’ll hopefully be able to help with the deposit though he’s saving hard too. I couldn’t both buy her out and gift it and neither would I want to - he’ll pay his way. With upgrade that we could do with the help of professional builders and family skills he could increase the value significantly. The semi next door has sold for £200k with upgrade but half garden and no off road space.
Is it fair of me to try to buy my sister out at the current market price knowing the upgrades will increase the value? She’ll know this too. The family skills will come from my partner and my son’s dad rather than my sister. She can always refuse of course and I’d make sure she takes advice.
I think she’d probably love the idea of our childhood home remaining in the family for a while longer, knowing her kids weren’t potential buyers. But I want be fair and need objective views. Cheers
