I did it, it took some effort and flexible work arrangements, but I started as an experienced real estate professional and my job was lending so I had access to a lot of free advice from my co-workers. 

I would consider tankless for your personal home where you personally benefit from any utility savings and where it is easier to arrange the descaling. 

@Bryan O.Curious what arrangements you have with them.

As I see it my options going forward in NYC are my employer extends the current arrangement, I renegotiate for local package, or get a new job.

Specifically, I think they should arrange a discounted sale even if that means they lose money.

FYI we've changed our approach entirely and have lower fee initial entry points to avoid the challenges of long term project based arrangements so we can catch issues much sooner.

The seller was great, arranging with Furnished Finder to transfer the current listing to us.

@Cedric Van Duyn it depends on what you suspect, if you think they are cooking meth then arrange for inspections routinuely so you can identify issues as this will greatly impact neighbors and you because of chemicals used.

Maybe thee is a happy medium that can be arranged.
