@Tony FerreiraYou have good options based on the limited amount I could gather based on your post.Shot you a DM, please feel free to follow up if you'd like!

AbelThe question was based on one month, though I’m looking for a sustainable process to put in place.

Love to touch base and explore more together!

In Florida, you get grandfathered on property taxes based on when the value you paid when you purchased each property.  

In my experience I have had some builders/manufacturers push back against this process but if they want the business then they will typically play ball. 

You will learn a ton here :) I am based in San Jose and invest out of state in Ohio and north Kentucky.

Unsuccessful Property Search: Hours spent on unsuccessful property searches, where no purchase is made, do not qualify.On-Call Periods: Instances where you are on-call but do not actively perform work do not count towards material participation.Meeting Requirements:Maintain Detailed Records: Keep accurate time logs and records documenting your involvement in material participation activities, supported by evidence such as emails and calendar appointments.Seek Professional Guidance: Collaborate with a qualified tax professional to ensure compliance with IRS regulations and to optimize your material participation strategy.I hope this high-level overview gives you insight into what activities matter and ones that do not.

I would not start investing, creating businesses, or doing anything in life based on a unicorn example, whether it be real or imagined.I would look at the industry from the top down, figure out what realistic margins are, and see if I can gain a competitive advantage or beat general market returns by a few % points.
