This is RE in the south(warm state). 

Everyone has different perceptions for B Class and this is mine based off our market in Toledo.1) Mix of investor owned and home owners (Last few years leaning more toward home owners buying)2) Infrastructure supporting tenant and home owner demand (Car manufacturers, ProMedica hospital, Washington Local School District, Toledo University, etc...)3) Homes well kept, yards mowed, none or very few bordered up homes, cars with wheels, pride of ownership, lower crime, no riff raff roaming the streets lol4) All tenants employed and submit rent payments online.

Lender communication was trash but fees were excellent (Universal Financial Mortgage Group).

My name is Ryan and I am a current Student at Western Michigan University. 

There are a few books but you can also check out MHP University by @Frank Rolfe

Charlotte's burgeoning financial and tech industries create a dynamic rental market, while Durham benefits from its proximity to top universities and research facilities, part of the Research Triangle.

I am a senior at Western Michigan university looking to connect with lenders to help me with my final graduation project. 

Proximity to job hubs or universities ensures a steady pool of potential tenants, minimizing vacancy periods.

However if you are in  a beach or warm market, leather might be not be popular.

We haven't been able to find a solution to that problem and it's likely caused but global warming and pollution so it's difficult to see a solution anytime soon.
