I personally just use zillow's application feature.

Make use of tools like PropStream or Zillow’s market analysis feature to assess property values and rental potential.PS: Did you know that Indiana has one of the lowest property tax rates in the country, making it a relatively cash-flow-friendly market for new investors?

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

The development is expected to bring thousands of permanent jobs and promote sustainability, including eco-friendly features like walking paths and tree plantings.

It sounds like the podcast you’re looking for might be the one featuring Jeff Thorman from HomeRenovisionDIY.

Special features are what set Airbnb apart.

Now they have a feature on their website to have a rent determination before you get the tenant.

I would suggest looking up similar rentals in the area to see what the trends are and what features are offered at the price point you are expecting.

I do know that the pricing varies based on the unit count as well as what level you sign up for; but overall, it's super user-friendly for tenants, PM's & owners.Plus they're always updating their software and adding new automation features to make everything so simple as well as well as great customer support. 

I personally use Buildium but I'm always looking out for new features and pricing models from the others.
