If you want to potentially save some cost on MLS purchase then you can communicate directly with listing agent and go unrepresented.

Hello, I wanted to get feedback and thoughts from Investors and Real Estate professional on a potential tool that would use machine learning and AI to create scores or ratings on real estate markets at the zip code level.

Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

Focus on finding a great first property with good bones and solid rental potential.

If you have a lot of faith in the potential buyer I would consider whether it was worth pitching on being a 50% partner for $25k.

Anything shady could become a habit, and potentially land you in trouble.  

HOA fee will probably continue to increase, you never know when an expensive assessment is around the corner and there is some potential for a price crash as they are really overbuilding (imo).

Any advice, tips, or potential collaboration opportunities would be warmly welcomed.Thank you for taking the time to read my introduction.

I've got all of my ducks in a row (financing, agent, multiple potential deals).

You should be 100% fine as long as you do the proper research into your agents, pm's, etc...
