It could be some sort of skill set for renovations, design for furnished rentals, specific market knowledge, owner occupied loan products for a house hack, etc. 

Specifically, I am looking at partnering with an individual who owns securities (stock and mutual funds) having them take out a line of credit against their portfolio (SBLOC) at a low interest rate, and using that to purchase properties rather than using a mortgage.

it may be jurisdictional specific, but it would certainly limit the sources for providing credit reports.  

I'm a STR owner / manager located in Texas (Bryan /College Station, TX specifically.) 

Rent control laws are market specific.

Those effected go well beyond the property owners, the economic contribution of RE and subsequent economic loss in the form of: management, maintenance, landscaping, caretaking, hospitality, tourism, contracting, designing, pools and gardening is economically catastrophic and will reverberate well beyond specific zip codes.

@Cody Ford Without having specific expenses and the 4th rent amount I can’t say for sure if I would pull the trigger on this property.

MANY things can affect the title to a property, not only issues that are specifically recorded as a public record like a mortgage.

Are you interested in a specific startegy (brrrrs, flips, vacation rentals, etc)?

Call the zoning department again, and this time ask specific questions: Is a variance required, or can you proceed as-is?
