Many years ago, my grandfather purchased a holiday home in the USA which was passed to my mother when he died. I am a former USA citizen who is domiciled in the UK and a UK citizen. Before my mother passed, she put the house in mine and my brother's names. That house is now being sold and my share will be sent to my bank account. How would I calculate the gain (from when our names were added to the deeds?) for my share?
