I am also a lp with a syndicator that does the same thing on a larger scale taking advantage of a San Diego law that allows them to add as many units as fit in the existing structure.  

If you plan to scale your vacation rental empire you may consider outsourced management.

(Both be profitable)In a contractor/investor relationship when built you need to find a real partner with whom you can negotiate so prices don't scale. 

I want to scale with concentrating on cash flow.

Initially, I wanted to scale quickly and get out of my W2 within 5 years.

This will come in handy as you begin to scale.5.

I understood back then that for me to build and scale the business, I needed to always make decisions based on numbers and not emotions, and that's one big reason I've kept myself in the industry now for 4 years.I see a lot of people getting too emotional after their first proof of concept, and most of them are not in the business anymore.

As an investor this allowed me to scale quicker having that flexibility and not needed to put down cash for construction (I can tell you about my first flip) Happy to help!

I'm about to be 25 doors under management, and I'm looking to significantly scale this further.

You already have a successful business and you should put your energy towards it and look for ways to grow/scale that business.
