But my opinion is this: If the numbers work out and you are not making a profit on house hacking or making very little profit on a house hack.

Deal was originally marketed back in 2018; I ran the numbers and they didn't work out at that time.

As a property manager, I always like to meet owners in person.Hope things work out for you.

I wouldn't being a realtor is really hard to do successfully, it is essentially starting a small business, I'd either go to college or get a job and become an agent as a side hustle, that way you have a fall back if being an RE agent doesn't work out. 

If there is a way for you to work out a way to get a portion of the rent and check In on them moving out and you work together to make it happen than you may be able to save yourself some headache, time and a little money. 

I believe they have the capacity to handle property management on a large scale like what you're looking for

In what capacity are you speaking of?

There's a refinery near by that contracts work out to guys who usually come in and work a couple months at a time. 

2 - How important is the local employment opportunities to a professional that will usually commute and/or work out of their home?

It sounds like the original developer/builder had a bigger lot and subdivided to get more money per lot... not other way around :P Not sure if your plan will work out for the best here!
