It is surrounded by a cabinet shop on the left side, a couple commercial buildings in the back alley that are used primarily as storage for various businesses and a bar on the right side.

I had failed to do this and it costed me hundreds of dollars in repairs.

Generally I would say that if the property is 15+ years old and not recently completely renovated a SFH would likely be in the range of 50% and a multi unit likely slightly lower, possibly as low as 40%, due to more tenants, higher cash flow and lower risks from vacancies.The 50% guestimate is based on the historic average of hundreds of thousands of rental units of all types over decades of accumulated data.

It will cost you a couple hundred bucks. 

I can team up with couple of agents but  Roofstock or HomeUnion are working probably hundreds of agents therefore would cover more markets.

The only difference was it had parking for one additional vehicle, the cabinets and countertop are newer, and it has a larger deck. 

If you have suspicions because of the hill, pay an engineer a few hundred dollars for an inspection of its condition.

The property has 1 move in ready side and one side that is just drywalled - not a cabinet, sink, or fixture to be seen!

There's lots of Rta cabinets out there.
