Can anyone please advise me with the best thing to do with Mums house? My mum owns 50% and my brother, sister and I own the other 50% between us. We have set up a deferred payments scheme to pay for Mum's care home costs and we have currently accrued about £35,000 against the value of Mum's 50% share of the house. We are thinking of the 3 of us buying Mums 50% share but not sure how to value it. We have been advised that a 50% ownership in a house is worth a lot less than 50% of the market value as very few people would like to buy half of a house. Please can anyone advise how to get a valuation for half of a house? Any advise would be welcome thanks.
