All of the major components can be and are outsourced or spec'ed out to 3rd party OEM's. 

The odd part is that the room entry is right off the front entryway where there's a tiled landing.

The CEO never had much money before and starting partying with girls and then started taking heroin.

So you want to screen for a good tenant/buyer and not just accept the first party who is interested but has little chance of ever qualifying for a loan and cashing out the owner.Also I strongly encourage you to consult an experienced real estate attorney to make sure you are complying with state laws (specifically your state's real estate commission laws). 

Quick question.....do you and your roommate plan to throw parties during the next 2 years?  

I've been happy with them for the most part, I don't use their leases.

Most of the time they are a 1-and-done deal... but if it looks like a repeat buyer, both parties should plan for a long term strategy. 

Predatory lending can go to the party that devised or introduced terms, it's not just on the lender's back with seller financing.

Tell them if it's not a good fit for them you can look toward finding a solution to part ways in a way that is fair to both parties.  

I don't know if you're aware but this building is under rent control and the 2nd unit's $1,900 rent cannot be raised much and there are tight restrictions on removing the tenant.The type of buyers this property is perfect for are two separate parties (think friends or siblings) buying it as a TIC with each party occupying one unit.
