You will want to narrow down your exact criteria to maximize your time. 

Your first step should be to REALLY narrow down your goals.

I've narrowed my search down to 2 markets, however I cant decide wether to go for 4 units or just a duplex to start. 

I've been narrowing down my search and I'd like to start in smaller, commercial multi family (5+ units).

I decided I didn't like the political climate of property laws in a few other countries you mentioned when I was narrowing it down but of course we are likely looking for different things. 

You can check out the Book on Managing Rental Properties, yet again by Brandon and his wife, Heather Turner, also full of invaluable information.There's some pretty narrow-minded individuals on here that will try to give good advice, but maybe aren't the best to learn from.

I am new to Note Investing and trying to formulate some guidelines that would narrow down the many aspects of getting started.If one were to seek out 1st/2nd/PN/NPN notes, are there any states you would recommend staying out of until more experienced?

(that's a huge question)To narrow it down a little it might help to give some examples of what you're thinking about.

Hey folks,I'm new as well and have just started visiting home to narrow in on what I'm looking for and to get better at "eye-balling" rehab problems/opportunities.I'm with @Paul Day - that Real Book of Real Estate provides an amazing overview of how vast the industry is and where you can pick a speciality.
