I was just watching a video on youtube last night about buying short sales and foreclosures from the bank. 

Get @Michael Blank syndicated deal analyzer and go through the videos to learn how to use it and underwrite deals.

@Phil Gilkerson @Scott Meyers is a great resource as well as Mark Helm has over 200 short videos on YouTube that's all things Self storage.

Never stop those YouTube real estate videos lol.

I’ve seen it somewhere but cannot find the video that I watched.

I am currently studying books and videos to up my preparedness for when I take some action in the next couple months.In my study of investment analysis, I'm being introduced to investing concepts like IRR and discount rate, which I am finding very confusing as a beginning investor just trying to get one property going. 

There are books (I like audio books that I can listen to in the car), podcasts, Youtube videos (though I haven't watched any of them myself - maybe I should), and of course people selling training programs on Wholesaling (I actually bought one of these, and it was great!). 

If you haven't done so already, I would highly recommend you check out Brandon's guide on tenant screening, found here: https://www.biggerpockets.com/blog/2013-01-27-tenant-screening and also check out Graham Stephan's YouTube video on his screening process here: https://www.youtube.com/watch?

Have done numerous walk thru videos of properties he liked after reviewing the comps.

Yes, I have seen youtube videos of this and the process it entails.
