I come with a different set of skills and experience, which is still related to what most folks on this site are doing yet it is still different. 

For you New Yorkers (not NYC), where can I look up when a property’s C/O expires?

Print your flyer....take it to all the investment clubs....put it on Craigslist and all the other fsbo sites....and if you really want to open the market....get a realtor to put it on the MLS for you.   

I have a good property manager that I found during my visit to the city but always trying to find like minded people.

Google and other sites have keyword generators or suggestions, but I just can't find what I feel I'm missing. 

I was clarifying your statement "officially...sometimes realtors will submit the sell price to the MLS, but it's unofficial and optional),"Agree - the MLS Sold Data is not transported to any sites without REALTOR access, and does not attach to the deed.

When a target property surfaces, be prepared to act on it within HOURS not days.Be prepared to show a solid proof of funds (not a print-it-yourself POF from a hard money site) and to submit a reasonable offer (most likely 97%+ of asking price).And if you have a good agent, you'll get that property under contract and start you due diligence. 

How often do you have to visit the job site to ensure project is on schedule?
