You will learn so much and meet so many awesome people! 

I tell people that real estate investing with me is more like a disease than an occupation.

A lot of investors are (wisely) wary of condos because condo fees can rise and special assessments can eat up your cashflow.

Are there non-disclosure laws that prevent transaction coordinators from sharing information with other people?

IRS liens are no big deal.. worse case you just have to hold the property about 180 days and they fall off.. many people get scared of IRS liens myself I would target those as I knew many would not bid because of it.. 

Now is not the time to be asking those people...terrible advice imo. 

You will need to be persistent, possibly patient, network with many people, etc.  

I had about four times as many people attend my high school.

Bought a home from some people that were about to face foreclosure.

This ensures they are keeping an eye on everything, they get to see what it's like to be a landlord, they have to take responsibility for the lawn and other maintenance, they will learn to deal with people issues, and more.
