Would someone please explain what "non-standard construction" is and why does it affect price.
I agree, no floor plan, not great pics or pics of the "pluses" and it looks like it needs a lot of updating. Small shower, stickers on walls and glittery looking room would turn me off, along with the short ceilings in a few of the rooms.
Perhaps do some updates that aren't too costly? Paint on walls, removal of stickers, painting the woodwork and better lighting would help, along with better and more pictures.
