Wife sold a letting property in 2019-20 and now needs to calculate the CGT on it.
She jointly bought this house with husband 20 years ago and inherited the remaining 50% on his death a couple of years ago.
When calculating the gain on her tax return (in simple terms) would it be either:
1 - Sale proceeds less original purchase costs or;
2 - Sale proceeds less (50% of original cost + 50% of probate value).
