It might be - now that I'm retired from the "day job" perhaps I will write it :)

I’m retiring as a firefighter and I’m ready to start the next chapter of my professional life.  

I have been able to keep a full time job but now I want to retire from my profession and either work for someone or start my own management company while I continue to grow my investments.

-They are the fastest path to help you accomplish your wealth and retirement objectives.

You can set up a management company if there's a purpose, such as generating qualifying SE income to fund retirement accounts and such/I highly recommend working with a REI tax strategist to make sure both of these are appropiately setup.

I am leaning towards the NNN lease, with the fact that we would get a substantial, reliable monthly cash flow in rent to supplement our earned income and delay any need to dip into our assets to support our anticipated early, partial retirement. 

One thing to keep in mind is that this could be with 'cash' or 'retirement funds' (we already were investing with out own retirement funds so were familiar with this).

. - likely two 3BR/2BA units).Both would be managed remotely, though we have a lot of family in the potential STR market (retired parent who could help) and we could use the STR unit ourselves for 1-2 weeks per year.

Those of us who worked for a number of years before starting often have more capital, plus often more wisdom and more connections than people that start in their 20s.I retired last year, three years after my wife and over a decade after we started investing in real estate.
