I don't invest right in the city but I do invest south of there so if you end up looking at places there feel free to reach out if I can offer any insight.Jeremy is very correct - zip codes won't give you a good idea of price. 

JV, GP-LP so you leverage other peoples creditsThere are a few other ideas.

First thing I'd do is check comps to get an idea of the demand and rates you can charge for your condo as a MTR.

Many investors in NY like the idea of house hacking because:- They can invest with a low down payment (similar to what a 20% down payment would be OOS)- They gain hands-on acquisition, project management, and property management experience.

Not sure it will replace GC estimation but at least will give you an idea. 

Same idea. 3.

I'm open to ideas and subjects/information to research in case there is something I am missing or just don't know to look for yet.Thanks all!

At least plan B does not sound a complete bad idea now.Thank you!

@Jonathan Boyd Hi Jonathan, do you have an idea where propstream gets it data from directly?

Connecting with an investor-friendly agent in your chosen market is also a good idea.
