Selling a retirement flat

[Nikkinoognarrrr]

I am looking for some help on selling my late df’s flat. We are struggling to sell (18months) as there are always 4 or so on the market and they can’t be sold to anyone under 67.
We have changed estate agents and lowered the price once.
It is now costing us to own it in fees etc while it sits empty.
I suspect it is too expensive but would like kind suggestions and thoughts on how to get it sold.

The pics dont do any favours at all specially 15/16/17 its looks like a Drs waiting room.
A complete updo is needed get rid of all furniture far better empty,looking at the kitchen area running onto the lounge I would personally put a room divider in place to separate the two areas,just a thought.
