My concerns with selecting a servicer are the following: customer service, access to funds, access to education materials so I can learn how to stay away from prohibited transactions.

You should have an agent with access to AirDNA to get a better idea or income. 

I'd also pull the records at the registry of deeds to see if any restrictions are attached to the unit. 

Where these restrictions exist, they are recorded on the title.

High demand in those locations pushes rents and prices consistently higher year over year, access to commuting and metro reduces vacancy, much more demand for room rentals south of 200. 

You need multiple exit strategies because the condo association can restrict or outright eliminate your ability to rent out a condo regardless of whether its an LTR, MTR, or STR.

Lastly, don't overlook any local regulations or HOA restrictions if any.

I know plenty of investors who will happily pay one of the many firms out there who help place equity so they can focus on their core competency which is running their real estate business (me being one of who would gladly pay a fee so for access to equity and the ability to focus on what I do best as a developer).

I am a real estate broker and have access to market data for valuations.

The city approved rental license inspector essentially just tested to make sure there was access to hot water, access to heat, no unsafe conditions like exposed electric wiring, CO/smoke detectors present/functional, fire extinguishers present/not expired, etc.
