We are a team of five employees, and our work involves renting land for a number of years, designing and developing buildings, and managing them—including renting and maintenance.It’s an exciting yet challenging new chapter in my professional journey, and I’m eager to learn and grow alongside all of you.One of my key goals is to modernize our company’s workflow, which is currently reliant on traditional pen-and-paper methods. 

I have a title report from my lawyer, but it is somewhat confusing as the land has been subdivided (it started as 9 acres and is now 1.5) and has quite a few transactions - including to the county (I.e allowing the county to build a road).

If we were to find a duplex/triplex/fourplex that met our criteria, I was thinking about maybe owner occupying one of the units in exchange for being able to use the 203k loan - for not only cheaper financing but 3.5% down + being able to include fixup costs in the mortgage.

I agree with everything @Michael Baum said.Many people, including myself, have used a 10% down second home loan to buy a property used for a STR.

The AAR does NOT include dividends.

Your net income includes equity from debt pay-down.

Everything should be done in hosue, including owning the property, renovations, and management!

Based on the above is my understanding correct and the 45 day identification period and 180 replacement property purchase period (which includes the 45 days) both extended?

This includes converting it to a rental property or refinancing into a different kind of loan. 

The good news is that these properties can indeed be purchased for various investment strategies, including rentals, BRRRR (Buy, Rehab, Rent, Refinance Repeat), or fix-and-flip projects.Purchasing as a Rental or for BRRRR:You can acquire a Freddie Mac home to hold as a rental property or implement the BRRRR strategy.
