Hello and welcome to the site. Thank you for your question.What is the property value at the time of death for IHT purposes?If the market value of the property is £200k at the time of death and your sister gives you £100k to buy you out, then there is no gain on transfer of property from you to your sister.As there is no gain, there will be no CGT payable.You will not be taxed on the proceeds from sale of your share but only on the gain made, if any.
I hope this is helpful and answers your question.
