Not discussed enough - even if I don't get great cash flow I'm capturing 15-25% equity at the buy (increasing net worth on paper).

No work was done to the properties and in most cases none were even rented out .

I'm renting them as non-traditional units (6 of them). 

I bought this property in college, renovated it while renting out the spare rooms and no use the property as a long term rental.

BrightInvestor offers a ton of market data and property data like crime heatmaps, appreciation rates, income data, and even off-market deals with automatic skip-tracing, analyzers, sales comps, and rent comps. 

Current total monthly rent is $2675.  

They are worth more, you attract better tenants who pay more rent and treat the properties better.We replace 3 or 4 driveways every year.

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)?

I post this because, in my area, the numbers just don't work, and worse, rents are under increasing pricing pressure.

Yep, exactly what I see all gurus pushing: Class C/D properties, section 8 "guaranteed" rent, etc.
