By day, I'm a video producer and operate a couple of LLC's doing production work and my only retirement setup at the moment is a Roth IRA.

What are the best videos / resources I can use to calculate where MY personal number goals should be?

I've been going through Brandon's videos while I search for properties.

I started watching videos, books, info i could and immediately implemented marketing suggestions asking if sellers/FRBO's would consider doing a rent to own.

I've watched videos on how to target tax delinquent properties and I have found how to access properties on the tax deed sales list (from Max Maxwell and other notable investors).

I watched a Tracy Z video where she illustrated the "1/2 the note for 1/2 the payments" thing. 

According to what I heard and seen from heartbreaking first accounts/videos and sources of events that tragically unfolded in Paradise, CA; a very peaceful town of about 26,000 residences were all mandatory evacuated a few short hours after the fire first ignited early Thursday morning...According to a CNN article, "The Camp Fire left the mayor of Paradise, population 26,000, in shock.

Good question, I became almost addicted to youtube videos, and podcasts before I bought my duplex.

Is there a good video showing how to use the Biggerpocket BRRR calculator?

The only one I have found though is GoM1 - of which there is very little information about online except for the videos they put out.
