Zillow has a lot of valuable information, but keep in mind that it's algorythms don't work in every market. 

We now invest in the Detroit market place where we have established a great team on the ground and are finding properties with great numbers.

They have been managing fine, although not too busy, I guess because of the market.

You can get screwed on changing markets and unreliable contractors though.  

The garage and the fact that a long term tenant was in place paying market rent.

Quote from @Brendan Jones: For the homes, and or properties that you will use as a primary or a rental property one big thing I look for is infrastructure in the area, extrinsic value (I.e. hospitals in the area, schools, and job market), and the last thing is creature comforts for people (I.e. is a store to get groceries 1 hour away or 2 minutes away).

What marketing efforts are they going to do outside of just posting in the MLS.

Purchase price: $85,000 Cash invested: $60,000 My initial strategy for this deal was to flip it and sell it, but the market was unfavorable so I opted for the BRRRR strtategy instead.

You can increase rents if the market supports it.

Those are all going to be good market.
