(If you did this, obviously, you would have to cover those needs, when they arise with money from other sources.)I imagine my beginner perspective is probably inaccurate in several ways.

I imagine it's higher than a typical single family rental considering it looks like the host usually ends up paying for any damage caused by tenants due to a variety of reasons (tenant refuses to pay, damage happened in a common area and it's not clear what tenant caused it, etc.).- Rental loss - PadSplit claims they collect 97% of rents, but I've spoken to a few hosts who have said that a much larger % of their tenants get kicked out owing $500 or more in back rent that is rarely ever collected - what's your experience been here?

When I was made aware by a colleague of mine I emailed them.

As you can imagine, our STR market is largely shuttered. 

You can just send the link to guests directly through messaging or email.

Skip trace and call/email them too. 

I post my properties there as a 1 bedroom and when I get emails on it I have to let them know it is a room for rent. 

If you find someone (or multiple agents) who are taking advantage of similar marketing strategies, you can get more inquiries this way.Lastly, I'd recommend an email campaign to all buyer, listing, and rental agents who are active the same area as the rental listing.All the best!

They won't answer emails. 

Where they "see" value is what makes them interested in the home which is how they imagine it will be for them to live in.
