Sold House prices

[Maerchentante]

Until last year I lived in a lovely flat that I rented. Landlord sold and I moved countries.
I know how much he put it on for, but I'd still like to know how much it sold for - call me nosy if you want.

They completed in July/August but when I check on Rightmove no sold price appears.
Thought it a bit "off" so searched within 1/4 of a mile radius, I know several places have sold and all the prices seem to be on, before and after the completion date.

Is there a reason why this specific price would not appear?

Just delays at the land registry, nothing sinister. Our sold flat took about a year to show up there whereas our current home’s sold price was on there after 3 months.

Thanks - I guess I'm just being nosy.

I'll be patient then.
