I'd rather use scalability and profitablity to generate the wealth. 

Nothing wrong with that, but it isn't very scalable by itself. 

This is because section 8 is so scalable.

We don't entertain that as an option because it's not scalable in our opinion. 

If #1 is a possible thing to try, any suggestions on how a strategy like this would be scalable?

I will look into those groups, determine a specific deadline, and start thinking about a scalable approach to investing for my 2nd-3rd property and beyond! 

Additionally, the scalability of co-living models allows for diversification across markets, mitigating risks and promising sustainable growth. 

This is very high-touch and personal, but also not scalable in a meaningful way, and often times, unless you have something pertinent to discuss with each investor, some may view this as a waste of time (think in corporate speak: "this meeting could have been an email")Newsletters are very scalable, and with scale the personal touches are lost, since you are presumably sending this to thousands of people.  

@Nathan Emmert I saw you posting about Wave on another post and someone else said Wave isn't scalable.  

Being a seasoned specialized LO is more scalable.
