So whenever you are doing the class let me know so appreciate it.Thank you Carol Marshall

You don't mention how old this place is, you don't mention where this place is, but I think it's pretty safe to assume your place was once a big old single-family residence that was Mickey-Moused into a Section 8 duplex maybe fifty-sixty years ago and sits squarely in what is now a D-class neighborhood.Sell it.

Myself as a realtor pre vet its completely legal as long as not based on a protected class such as race etc. 

With C class, the easier it is to maintain the better, and shaker cabinets are in abundance so if you have to replace a door or drawer in the future that makes it easier.

I will echo everyone's comments: Find a good PM, stay in C class neighborhoods, know that it's a long game, and that you're going to be writing a personal check now and then if something big goes wrong.

You want to keep paying cheap rent but get an A-class rental in exchange.

For example, a 10% return (or reward) can be worth the risk if you are investing in a Class A single-family rental in a great market with an A+ tenant, but not worth the risk at all if betting on a 16-seed to make it to the Final Four in March Madness.Investors in mortgage bonds utilize the risk-and-reward framework when allocating how to invest capital.

They all busted *** for years, some took classes too.

Separating by classes allows for separate P&Ls for each property. 

I am new to real estate investing, and I'm beginning classes toward agent licensure in June.
