Within the entity, units or partnership interests are "owned" typically in the same proportion to the profit split or contributed capital.If the syndicator has enough folks to fund the deal with that structure, more power to them, but it's not scalable.  

Given that it takes time to build a scalable real estate business my advice to you is take this opportunity to read up on the niche you want to get into.

Not scalable.

I'm hoping to learn and get advice on how to help my family grow their "mom & pop" portfolio and help brand it into a professional entity to increase their current profit margin while maintaining scalable processes.I'm still a newbie but am determined to learn and hopefully make some money along my journey!

As to the project, it's scalable below $1M, but we're using very rough preliminary numbers at the moment.

They do a financial and background-check to make sure you will pay taxes.But ask yourself, is this really a fun, scalable, and lucrative real estate business strategy to get into?

Moreover, 75k'ish properties are more scalable with commercial lending once you start acquiring more. 

As for scalability, this is a slow and steady strategy to growth.

I'd also like to add, my goals are to get into larger apartment complexes mainly for scalability and gain $20k+ a month in passive income. 

If that is the case, the initial numbers don't support a scalable investment strategy.
