Today, those Studios rent for $1,900 each.So each apts moved from $500 to $1,900 in 17 years for a increase in rent of $1,400.If you bought a cash flow property outside NYC that was cash flowing $500 per month, but only doubled in the 17 years to $1k per month, you would still be short $400 per month because your rent increased $1,400 versus your outside cash flow property which only increased $1k.I can't emphasize that if you instead bought our place to live here rather than rent, you should think of it as hey, I'm actually doing better than the above scenario of buying outside cash flowing properties!

Did you review that terms of the agreement with the tenant and emphasize key points?

Just to emphasize @Gino Barbaro .

I’ve sold listings this way before and most other brokers emphasize marketing to buyers(which is still very important) Be honest and tell them you probably won’t be the agent bringing a buyer.

I am looking for some learning resources how to do what I explained and emphasized in my first post what are the biggest challenges for me (see quoted sentences).3: I apologize but i disagree here.

Maximizing the NOI remains a huge focus, so thanks for emphasizing that again. 

Treat them with respect, explain the contract to them, and emphasize how your are in compliance with it.

The thing I always emphasize the most is SCREEN, SCREEN, SCREEN.

A few things need to be re-emphasized:  These are not MY  numbers, nor are they MY deals. 

Look to those which will emphasize cash flow over appreciation.
