Narrow it down.Are you interested in C or D properties for 30K-50K?  

@Bryan Bagge I wouldn't touch a C or D area unless you have a lot of experience, the building is in decent condition, and you have a good contingency fund for repairs/capex. 

I am a newer investor in MFh and I don’t feel I should skip over the more general education that normal class c or b mfh offers.

The market aspect of it has let people bet on what is basically startup software.

I have some properties getting higher rates of return, but they started in rough shape, are in C or D neighborhoods, and are rented by people with credit issues.

Once an investor is satisfied with the return and risk - they bet on you and your team's ability to perform.Don't discount the issues with passive investors.   

***Only exception is if an owner has plan & funds to reposition Class D to Class C or higher.https://www.biggerpockets.com/forums/776/topics/960183-what-they-dont-tell-you-about-cheap-rental-properties?

If value increases and you have the intent of one day dumping the property to get all your money back plus some, then bet on the come.

based on your description, I'm guessing your property is C class or lower, in a C or lower area?

In a lot of C or D class areas it can be very common to have habitual late payment of rent.
