This is on top of my own scrubbing of Airbnb, Vrbo etc. for the last two years. 

The upgrades also help along our appraisals, of course, which always need as much help as they can get.We have washers and dryers in all our units, but I also offer to put in hot and cold outlets and electrical for a tenant-provided second washing machine in my rental properties for free, again, something no landlord would normally do and no tenant would normally care about -- yet 50% of MY tenants have gone out and bought themselves a second washing machine to wash their scrubs in.

We removed a rotted wood storage area and bleached/scrubbed the entire wall and sealed it.

This was the thought that was going through my mind while I was scrubbing black mold out of a cabinet using a sponge and comet cleaner (worked surprisingly well BTW).

I also plan to send SMS and RVM once I have scrubbed the data against the DNC. 

Once they've run through the list a few times, I'll scrub it and compile a list of who didn't respond.

I was thinking keep the option fees low and really scrub the applications to make sure the people can actually by the house down the road? 

Yes, many many MANY scrub agents will offer to sell your house for some low percentage, but their past sales will stand as a testament to their worth. 

Starbucks generally has a specific tenant rep broker scrub their sites for certain areas.

One more note, scrub your social media of anything you would not want your Boss to see.
