C-class locations can make money but your operatins need to be on point.

If it was a Class A property and you had to make it really nice in order to fetch premium rent, I could see spending money on it.

Maybe this is d class area where collecting rent has challenges, inspection should be done often, lots of tenant conflict, etc.  

., but SFH's are one of the more inefficient asset classes to own.

The unit is coming up for rent again soon and I'm wondering if I am opening myself up for a claim of discrimination with this process - where a tenant who is not chosen could claim that I rented to someone else based on their (fill in the blank of protected class)?

But the treatment after Maria make it clear its going to treated as a last-class part of the US. 

If you want to get around this simply require ALL credit reports be given to you for the purpose of supervision of your agent to prevent discrimination against protected classes under the Fair Housing Act.I would not pay any lawyer a dime if they could not prove this appropriate business purpose.Does the person that wrote the following sentence practice out of form book?"

For my realtor clients I always recommend class A- to B- 4 units, these actually cashflow without being heavily hands on. 

How much would I have to increase my price point to start finding viable properties in B-class neighborhoods?

The literally single biggest mistake that people make is to buy a class D property, because it was cheap to begin with, 90+ days on market and they were able to negotiate a "discount" - ask them a year later how that worked out for them.
