I've read nearly every biggerpockets book, listened to nearly every podcast, joined a local meet-up, and spend hours on Zillow and Trulia practicing property analysis on local properties (mostly in New Castle).

This is just another example of what can happen when the Government gets involved with (IMHO) sensible and responsible practices of landlords and the Gubment looks for reasons to restrict and fine them.  

Is there a common practice to shop this deal around (for funding) to let's say private lenders, without them theoretically stealing the deal (Property) from you?

FYI, I'm no longer a practicing (or licensed) attorney, so none of this is intended to be legal advice.

That being said i would strongly recommend one for a couple of reasons.Until you have a solid understanding of the ins and outs, standard practices and the risk involved its always the smart play to enlist someone that does, also you will need a title company as well and most RE attorneys i deal with also take care of the tittle side of the house. 

The 1918 was practically the stone age compared to 2020.

I think there might be some bad debt collection practices if the repayment was solicited when no debt was owed.This sounds like a scam, to be honest. 

It's a big book full of practical advice from marketing, screening, leases, collecting rent, etc.

Don't feel bad, this is exactly why 80% of borrowers mis-state their income.Your math implies that there are 4 weeks in a month.If there were 4 weeks in a month, and 12 months in a year, that would imply 48 weeks a year.But there are 52 weeks a year, because there are not EXACTLY 4 weeks (28 days) in any month, excluding February.The instructor is correct, that's the exact math I did in 2 seconds when I read the question. 14.50/hr times 30 hours a week times 52 weeks divided by 12 months.In practice, this is unlikely to be the actual number that an actual underwriter would use.

Watch a couple of the videos or read some blogs on BP and then practice a few times.
