My intention is not to buy the sellers problem but to provide a solution.

Particularly looking for an investor friendly agent able to take on house hacking clients in NYC and LI

I may have to Teak my strategy in light of the excellent advice you provide here, Henry.  

I would also consider talking to her broker.Also, has she provided references from BiggerPockets or Google Business?

I have spoken with a couple real estate agents and they are scared to let me have the agreement thinking they are breaking some kind of code of ethics letting me have it.

Most will be licensed (as agents/brokers) in their states.

You really have to learn the neighborhoods or work with a sales agent who does.

RM-4.5 zoning would allow for a higher unit count and could provide more flexibility for future development, regardless of ADU policy changes.One potential benefit of rezoning before any citywide expansion is that it might allow you to lock in additional density rights ahead of any potential restrictions or revisions the city could impose when expanding the program.

Quote from @Shawn Questa: Hi all,I am curious what some of the Pros would do to Help a Seller in this situation while making a Deal happen.I found a 200+ day old MLS Listing where the Agent said the Seller is in Financial Ruin, hasn't Paid the Mortgage in a year, owes about 180k on an approx. 210k House and multiple Buyers have backed out.I don't know how someone could not Pay their Note in a year and not at least be in Pre-foreclosure. 

It certainly will help me to know what to provide for investors when the time comes.
