If those stop, I'd be making class action noises

I was taking Dave Ramsey’s FPU class but I got cancelled due to COVID19.

Don't let the limitation of money be the reason you settle for a lower class property.

There are different prices but most are around the same online or in-person classes.

What kind of tenant class do they deal with? 

That will then lead to lower appreciation if your area does not have enough development or if there are too many projects and protected class buildings.Safer Streets in Bed-Stuy that are away from low income buildings and projects might be able to capture the future appreciation or at least get higher income tenants.There are a lot of things to think about when you buy.

Getting a 5% return in an A class neighborhood is fine, getting that same return in a D class neighborhood is idiotic.

While you are not incorrect stating it is an established RE principle, you are incorrect applying it to this property class.  

Class B duplexes with rents ranging from $1,100 - $1,500. 

Are you in a good neighborhood (A or B class preferably).
