You’ll have to provide more detail. Were the seller and the buyer connected to you in some way?
Oh okay. So even if advertised for 100,000 and a buyer offers 80,000. The actual price paid, is the one to use and so therefor the price accepted when reselling. I am alittle bummed as been Registered non resident, all the years, (35 yrs+) out of the Uk, and only this current Tax year, when I decided to sell, I am resident for all of it, due to Covid and in full time employment. Worked basically to pay the CGT it seems .
