This email has info about pets, security deposit, verbiage about checking the surrounding community, criteria to qualify, link to my website where the application is and lastly a date and time slots for an open house.

I pay them well for this service, but I need it more than the luxury homeowner  with the fat untapped credit card balance down the street whose furnace also conked out on the same day.You need people who will be there for you instead of people who want you to slot you in when it's best for them.

There's a reason they have the money to spend on those expensive ad slots!

I'm getting ready to start a new STR and will give this a shot when I've got small empty slots.

Another issue will be identifying expenses vs capitalized expenses and how to "slot" expenses to appropriate accounts and managing any escrow accounts for deposits from tenants (that money isn't yours, it's your liability).

The buses of seniors pumping their SS checks into slots is over for this town and now seems to go to wherever the closest casino is.  

They were managed by an automated diagnostics system and the company I worked for dispatched the technicians for repairs based on the diagnostics server.

Quote from @Tom Server: If there is a written lease agreement, then you have to stick with it.I suspect there's no written lease, or it's expired.

I had one lady tell me she lost it all playing slot machines in a trip to Las Vegas (true story) and I wasn't impressed.

Don't use mail boxes, but mail slots in the front that many other do to avoid such problems.
