I looked at upgrading to turbo.. but I really don't care for oxygen at high elevations. 

Even though the condo has been in existence only for 20 years (previously it was a a school) I see that in these meeting minutes a recurrence of issues with the elevators.

If it weren't for this, I would have made an offer. waiting to hear from the agent about elevation levels and, ultimately, what the resident was paying for flood insurance (FEMA maps show it in the flood zone).

You must procure a flood elevation certificate, approx $600, from a reg land surveyor or engineer before I can quote.

I think it is wonderful, with your advanced education, in combination with living and working in NYC in an elevated capacity in the NYC real estate market, gives you some of that "NYC chops", that should go a long way to help you branching-out, on your own.A thought for you: Do you have the possibility of renegotiating your work agreement to changing to an equity position (a "piece of the action", an "equity position" instead of a salary.)???

After the speech, one guy, who was a real estate investor himself, approached to tell me how wrong I was, how the market was still going down and it was a terrible time to buy rental houses. 

I don't necessarily mean a bogus elevator pitch, I just mean why that makes you marketable as a partner.
