I use their free version and have had no issues. 

They get free housing and a salary.

They are free (or at least free up to a certain # of units) and offer  most of the same features  along with very friendly user interfaces for both tenant and landlord.  

Feel free to reach out if any questions arise.

When you start your real estate investment career, don't forget to do extensive study, consult with knowledgeable investors, and move cautiously.

It's free.

I have been studying my market since 2018 and that's just it, I haven't taken any action and just keep collecting knowledge.

From there, I look to create a site that clearly and succinctly communicates both what the business offers customers/clients, and what they should do next (i.e. list your home, signup for email list, get a free investment checklist, etc.)If you aren't involved, there's a good chance your marketing won't match up with your business.

To my knowledge, STRs do not qualify for the real estate professional status as they are seen as a business venture and not real estate activities (this is why it is a "loophole").

Then you’re free to rent it out.
