The numbers made sense (and then some) and the property (a 4-unit) was C-Class but in a pretty good neighborhood surrounded by SFH (which I consider a good thing). 

If you fail the exam for a third time, you’ll have to pay for another course and re-do the entire class then take the exam again.

Even a lot of tenants don't seem to be aware that in Cook County housing providers cannot turn down an applicant due to them being on section 8.

Some parents want lots of AP classes or special Ed programs or diversity in their school.

I'm not even talking about the quality of tenants you will drag on in these lower-class C-D areas, $800-$900 rent per month looks great on paper until the tenant stops paying and messes up the place. 

We're not a fan of MTM leases - except now that COVID eviction moratorium has hit we are using it on Class C properties/tenants.BTW: we can break our lease as easily as a bad tenant can:)You can put any increase you want in the lease.You can also do best offer or auction off the rental to the highest bidder.

I am new to real estate investments and I am yet to begin, I started a real estate investment class to get me grounded on the basics and I would like to start building my team.

I would also focus on building your knowledge base for whatever asset class you want to pursue (reading books, articles, podcasts, etc - no guru courses!). 

However, she has since learned that the lease in the upstairs unit is allowed to a pet, and has stated that this is unfair and likely violates Fair Housing protected classes.

I don't think either having or not having a fan will fetch more rent, but if you're in a nicer class unit, tenants tend to be less "hard" on properties and things like fans have a longer lifespan.
