I am putting in a link to something that may be help, a cost of living comparison calculator (https://www.bankrate.com/real-estate/cost-of-living-calculat...). 

I'm currently using a website that I created 4 years ago, posting vacancies by creating a page and cross linking it to a form in my website for applications.  

Here's the City link for you to reference. https://www.chicago.gov/city/en/depts/doh/provdrs/homeowners...1) ADU regulations specifically exclude Short-Term Rentals so don't do it if the intention is to short-term rental. 2) The ceiling height oh 6'10" is almost guaranteed to trigger digging a basement if you want to formalize as an ADU unit, especially if that height is further reduced by pipes or HVAC. 3)Ingress/egress is an issue for renting, as is that any bedroom also will need two (ie operable window/doorway).

A website like Pet Screening can help you verify and document pets to ensure they’re a good fit for your property.

Would that be, for example, if the PM says, "I manage a duplex for John Smith in Turlock," then I call John as a reference, ask John a few questions, and then ask John the address of his duplex so I can later look it up on the county website and verify if he is the owner?

@Chris SeveneyI agree it is not the most professional website I have seen.

Thanks for the link, I'll check it out.

Find out how long the tenant has to dispute this in your area and send them the link to that. 

The state website can also be very informative. 

I don't mind setting things up on platforms like AirBNB and VBRO and even setting up my own website for direct bookings.
