For Docs, we'd like to see a photo ID, proof of funds, proof of experience (if any), and info on who will be your boots on the ground for the project.  

You can't get eyes on a property easily, so you're trusting what folks are telling you, photos, videos, etc.

If, however, you are starting out fresh, and it is appearing as a new listing with no reviews, you could market it that way by taking fresh photos and giving it a face lift with the summary calling out that it is a new listing.

I always get a photo of their ID, I've only had one person push back in 3 years. 

The photos on Airbnb need to be professional (with the first photo being the outside or the kitchen.)

Any selling costs like professional photos or listing fees reduce the gain on the sale. 

Hand wrote the letters, added photos of their exact houses, sent out myself.

I'm happy to be a resource and answer questions for Nevada real estate and exchange some dog photos!

Sure enough some time later, he staged a trip and fall, photos taken with injuries.

Keep the beautiful images of your STR up and looking charming, set up your own free website with videos, photos of activities in the area, lists of restaurants, hiking, historic whatever.
