Sell of a foreign property without initial value

I am living in the UK since 2020. A commercial property abroad that I had a share has been recently sold. The property was inherited from my father in 2017. Unfortunately it has not a valuation in time of inheritance (it is marked as 0 in title deed). I have an official valuation report at the time of sell, would that be accepted to use the current valuation and official local property price index to find the 2017 value of the property? Second option is I can have a 2017 valuation report from a local estate agency, which I expect to be aligned with the previous option I've in hand. Thanks,

Hi, yes you would need to have a formal valuation to obtain a value at the time it was inherited.
Thank you.
