@Brandon AmdahlThis forum (correct me if I'm wrong) is of the belief that if you don't "self manage" your STR you likely won't make much money.

The common belief is if you buy SFR, it is for appreciation.

I'm working on getting my first STR, I had a call with a broker from The One Brokerage ( why not, I listen to Bigger Pockets Real Estate Religiously).

Contrary to popular belief, RE investing is NOT passive--it takes serious work (even if you have a good team managing your properties...you have to mange your managers, and that's a job).  ...the people who think it's a "set it and forget it" process are usually headed for a rude awakening. 

I'm of the belief, work smarter not harder. 

Moreover, for your basic but essential advice; save religiously, build your credit now that you're 18, limit unnecessary debt, etc.

Did the lender themselves stated it was “misreported” or is that your belief?

This shows how quickly cash flow can increase (but your units will be rent controlled and can only have rent increase of 10% = $370/month ($740 total for both duplexes)).It is my belief that it is a terrible time to sell and you likely would take a big loss. 

Crystal, I'll follow these steps religiously on my journey to the first property.

It is my belief that the $700/month average SFH YOY rent increase is in part a consequence of the extreme covid eviction moratorium.
