@Joe Kim yes OPM as in private investors to scale your business.

I've seen people scale to thousands of units in just a few years.

I am considering doing some BRRR SF deals but I currently want to scale faster than SF can allow so want to stick with a MF strategy for now (always willing to shift in the future if necessary).

They sometimes charge higher fees or interest rates but it’s the cost of being able to scale.  

Any advice on how to scale my property management company?

They have scale, systems, and team, but you won't get lost in the shuffle.

My goal is to build a long term buy & hold portfolio for additional cashflow in the Greater Tampa Bay Area and potentially scale to larger projects when I have a few years of experience in the game. 

I didn't HAVE to open the LLCs, but I chose to since I had some cashflow and scale on my side.

It's easy to stalk people these days, then get them on the phone and hear their perspective.Though it's different from what you're used to, I think you'll find the greater tax advantages and economies of scale favorable with large MF. 

You can scale it relatively quickly if you buy affordable houses and fix them yourself.
