This includes interior and exterior preparation, staging (even if it's just de-cluttering and improving flow by removing/changing furniture), and professional grade photography - which can be done by the agent but takes skill. 

Sometimes it's a little bit of TLC, or decluttering or good (ie, professional) pics for the MLS.

My home I purchased for 130K and after rehabbing it with a family member it may be worth 180-190k+ (new kitchen, bath, painting, decluttered, new carpet, turning the upstairs into a bedroom to improve value).

As a new years resolution I am cleaning out, throwing out to get organized and de-clutter.

It's a great way for a tenant to de-clutter & get some extra money for ..rent ;-)I'm sure you do have the authority to ban them.

Certainly it is not unreasonable to ask him to declutter an area to allow access to paint a section.

Anyone who is moving will often need to declutter their home, so junk removal is a perfect fit to people moving.

They know the price point they want to sell at and prefer to get there by dealing with one person who they trust to get it done quickly and painlessly rather than going through the whole listing process and dealing with flaky buyers, having to fix up, clean, stage, declutter, get the property ready and stay in a hotel for a weekend so 100s of people can walk through their property seeing and sometimes touching or potentially even stealing their stuff, reviewing multiple offers and comparing and differentiating between them then picking one that they hope sticks and turning down all the others, maybe they don’t like realtors or want to save on transaction fees, etc.

Declutter, depersonalize and paint.  

Then I went through a stage of extreme decluttering.
