Check your local laws and ordinances and take what I say with a grain of salt.1.

Curious what property types you are thinking about and if you are looking to stay in Salt Lake?

I'm looking to understand the local market differences among the cities in Utah - Salt Lake City, Lehi, Orem, Provo (or others), for Single Family or small (2-4) Multifamily Rental property investment. 

@Tom ConantI don't know your market, so take with a grain of salt.

They are "finishing" (to be taken w/ grain of salt in mx) an international airport in that region. 

Not sure where that map is from but wouldn't Miami or Orlando areas and parts of Colorado (Denver, Boulder) and Utah (Salt Lake City, Park City) be considered "not cheap" so would be in red?

The books mentioned on these forums  like The Millionnaire Real Estate Investor  etc and also googling on  youtube and going through AIRDNA , Awning And Rabbu ,,of course take it with grain of salt,,

As for what what @Alan F.. said, you have to take it with a large grain of salt because its not a good idea to blindly take advice from someone who sells a service/product.

If you can't be called names and either defend your position or take the criticism with a grain of salt and keep it moving, RE is probably not the best business for you.

So I have a very unusual small business wherein I take out my pianobike (a piano and trike fusion) and busk downtown in Salt Lake City.
