I kept researching for a few days as my head spun with doubts.

Sale Price$171,000 - $55,000 (Rehab) - $13,680 (8% fees) - $40,000 (profit) = $62,320 MAOFrom talking to other investors and doing research, typically a Novation allow more money to the seller, correct? 

New to the app & doing some research, I found this app might be a good resource.  

DM me if it would be easier to just have a phone call and we can try to narrow down (eliminate options) so you have a 1-2 to focus on and research. 

There i a bit of research that needs to be completed early on in order to get a good judgement on the feasibility of this; from there, the "Official" way to ensure you could pursue this would be to request a "Zoning Opinion Letter" to receive an Official decision from the Department of Zoning in order to ensure this will not cause any issues during your permit review. 

One thing I suggest doing as you do your research as well is to find a property on AirBnB that you like. 

How do I research or find sales comps from previous years, for example 2017-2018?

If it is in a C/D area I would not be comfortable with breaking even.It looks to be between Blue Hills and the research hospital.

Do some research before posting any restrictions.Also +1 on the inspection nuissance, in a pristine place the inspectors always "found" something.
