We are doing 300+ homes so individual LLCs isn't realistic in this scenario. 

I have a MTR guest that has stop paying and refusing to leave even after I sent him a demand for payment or leave the property.

Normally, the transfer of a loan from an individual to an LLC will lead to a due on sale clause. 

I've met plenty of individuals with far more experience than me who have offered referrals, advice and so on but I'm looking for more handholding than is reasonable to ask for someone to provide for free.

It seems like it basically up to you to do the math on how much more you will potentially make selling each unit individually and then deciding if that extra $$$ is worth the number of extra hours you will spend.

Check out padpslit.com, I use the platform to rent out 8 bedrooms in my house individually

The job market is strong due to major companies moving and developing here like Intel, Amazon, Google, etc. and there's a steady population growth and strong rental demand.

Quote from @Chris Seveney: This really boils down to each individual situation.

Aim for a 620+ credit score, save for a down payment, and research markets with strong rental demand.

They could positive cashflow and i believe there should be good rental demand from student population but i am not sure about the scope of appreciation in the area.
