If you got a buyer for low price, sell it. There have been some 4k sales in other extension but the scenario is very different from this one.
There has only been 2 sales in this extension and wouldn't be a stretch to imagine that sales in this are gonna be hard.
If you are looking at a 5 year picture and believe in the name or the extension, it is your choice to hold it.
I think it's not the best choice though.
