I've seen YouTube videos where people have done this.  

Dave Meyer did an excellent video for BP on YouTube for this very topic; multi family units.

I say in about 11 or 12 months I'll start by this time I can work my negative credit score up from a scary mid 500 and have sum capital set aside to use as a down payment and for rehab.. just would like to be referd to a few good books pod cats YouTube videos etc..I'm currently attending the real estate meets here but they are once a month.

Once we like the property, Can we hire a building inspector to get the property inspection report done with videos and photos to analyze the property condition?

I think @Beka Shea hit it on the head: are you just looking to add doors/income streams and you're okay with the extra work, or would you like to focus more on economies of scale in a larger property?

Here is the video of it.

Does anyone know of an audio or video-based online Real Estate school?  

I listened to the videos and read the material that came with the initial investment.

Andrew Johnson “I use Appfolio out of santa barbara, ca its definitely not free and my property mgmt company passes those costs down to me which I think is around 50-60 bucks a month based on number of units under the service.I am able to see all reports from rent rolls, cash flow statements / trailing 12 month cash flow, tenant ledgers, maintenance requests, dialog between tenants and mgmt staff, resolutions to maintenance requests, move in pictures, move out pictures, or video, and many more features.What I like is that it allows the vendors to be in a dialog/text/chat box so they are prepared (vendor) prior to job assignment with lockbox codes, scope of work and pictures before they even go to the site so we dont waste time figuring things out and run up a huge $$$ bill for lack of efficiency.”
