Analyzing these properties, I knew my only option would be a long term rental.

I plan on listing the property for sale 1 to 2 weeks before completing the rehab.What are my options?

My other options would be to Airbnb it (property close to Morgan State, JHH, and more) or rent it out to a regular or student tenant.

Other option?

I am not sure of the laws for NYC, but that may not even be a legal option depending on their restrictions. 

A bridge loan might be your best option here.

I would like a granite style, but not sure about the other stone options in terms of what would be best. 

If a seller is offering $10k in assistance but the PP is only $189k on conventional a loan with only 3% contribution allowed, what are all the options for the for any of the left over contributions after. paying closings costs ?

You want to go to meetups, meet people, and fall into a mentor by adding deal options, sweat equity, or some other skillset to help them.

An option could be doing some research to ball park what these estimates would come in at and remove that amount from your offer.
