Preparing a house for sale is a lot of work.  I have done it many times, and getting the details right is a lot of effort.  Even the final clean up of my new houses is a major undertaking and very costly.  There isn't a lot of point in going to the trouble of preparing a house for sale if the interior decoration is completely hideous.  I was browsing a Killarney area property currently on the MLS and noted some bizarre interior decoration.

This paint work could be rehabilitated for a small amount of money.  That minor investment would go a long way in making the house more marketable. I am surprised the realtor would not offer this advice to the seller, or maybe the realtor did and the seller just wants to list anyway.  It is hard to imagine this house getting the most value given its condition.
