I also have a little experience and understanding analyzing deals using Excel from school classes but would definitely want to learn more about that!

Predominantly will be looking to invest in B class neighborhoods with small multifamily. 

Most of the old warehouses vacant and for sale for $1 around here are really tough locations so spending millions to upgrade an old building to be in a C or D class area is not that enticing.My family used to own a large warehouse for dry ice production and distribution as the neighborhood turned to crap between the 1950's and 1980's they moved into a bigger building in a nicer part of town. 

In my market 5+ is considered commercial and lenders won't do VA in that asset class.  1-4 is doable here via VA.If your reading and studying has given you a good comfort level, most definitely jump in. 

I live fifteen outside of AC, and my family books Airbnb for Thanksgiving weekend to all get together and cook without cleaning.  

When underwriting apartments in the Metro Detroit area, what are your "rule of thumb" expenses per unit/year for B/C class properties?

Also can you describe the property (sft or multi, age, condition, etc) and neighborhood class?

I have been searching around for a little while and I cannot find any information or reference to online classes for an Idaho real estate license.

I think B-/C+ type stuff is the place to be, and Chicago is full of C class buildings in solid areas with a Chipotle or Starbucks nearby. 

How will I know that I'm in the class?
