He left behind some personal items and took a few of ours (it was partially furnished). 

I'm assuming the house and items on the property go with the sale?

Food for thought!

Talk to a couple agents and see what items on those list you can improve to save on your insurance premiums. 

@Adriese Williams follow landlord tenant laws with itemized list for security deposit and invoice requesting additional amounts that are over normal wear and tear and depreciation for age.

It's akin to making a booking at a restaurant and writing a positive review before you even get to the restaurant, experience the ambience or taste the food.

When you pull their credit, go through each item and check to see if they continually have high credit card debt, if they have any 30, 60, or 90-day late payments, ensure they don’t have any judgments or collection items, and see if they have any large payments that will hinder their ability to pay rent.

Other items to think about would be your hold time.

Much of their food would spoil and they'd be hungry, and most people don't have a proper stock of food and what do you think people will do when they're really, really hungry?

Another pro tip- right click on the photo in Chrome and do a reverse image search to see where the item comes from, it is usually way cheaper, and that's probably who Wayfair drop ships it from anyway.
