I'm totally fine using resources like books, online research, and AI, but I was looking for real-life, experienced individuals who could shed some real light.

Any recommendations of online companies with these services?

You can also go on zillow/FB marketplace to see what other similar properties are renting for around where your place is at. 

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?

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)?

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.

I left my job 2 years ago to help me and sister build a online business.
