Can't find any reviews online on that.

There was a post that I was interacting with on the Classifieds section where someone has a program that allows you put something like $5K down.

After some research online, I am reading that the cost per square foot on a gut renovation of this nature in Stamford CT is anywhere from $150-$350, which is ultimately not very helpful, because at $150 per sq ft, this is a very appealing project with a total profit of ~$175K (46% ROI) and at $350 per sq ft, it very much isn't, because it would be a net loss of 83K (haha).QUESTIONS:What can I do refine my estimate a bit given that I am not allowed to a formal inspection on the property? 

Again, the BiggerPockets store has some books on this topic, or you can learn about it by watching podcasts, reading blogs, and interacting on the forum.

Saw this program on Facebook today.Like all online coaches, I question if someone is bringing in millions of dollars, why do they need to be hawking a $5k course?

Do we just have a written agreement between father-son (is there a viable legally recognized agreement online to use)?

I'm shopping and ordering online given that my apartment is out of state and I'm flying in to set everything up.

In online forums, the danger I've experienced is the "national" effect. 

Method of choice was looking for potential properties online using redfin then when I had run simple numbers I would drive by each property and its neighborhood and if it was worth pursuing, I would schedule to see the property through the selling agent.
