If it’s so bad, instead of playing detective or code officer, why not move?  

Something that will really detect from his entrance.

I'm just asking for early detection.

Such a "wholesaler" should be weeded out of the marketplace by failing miserably in what he is doing.2.

If the rental is in town, maybe start looking on Craigslist, FB Marketplace and OfferUP for quality used furniture to have as backups?

I list the property for rent on various sites including Zillow Network, Apartments.com, and Facebook Marketplace. 

Just a bunch of uneducated dudes slappin whack stuff up on Facebook marketplace.

Meetup.com is a good resource for those but some of the groups will also post here on Bigger Pockets Marketplace too.

We want to experiment with renting by rooms.Here are the pricing we set:Master 150 sq ft (private bathroom) $1100Room 2 120 sq ft (shared bathroom) $1000Room 3 100 sq ft (shared bathroom, 2 walk-in closets) $950Here are the pictures of the house:https://austin.craigslist.org/roo/d/austin-spacious-newly-re...We listed the house on Zillow, Craigslist, FB Marketplace, Roomster, Roomies, TurnoTenant (which broadcasted to over 10 other platforms), Avail, FB groups, etc.

Personally I like Facebook marketplace but I get about 85% flakes who either just aren’t qualified or end up no-showing to the showings.
