Do the cold calling yourself and that is where the true magic is as you can see with @Peter Tverdov success at doing it and getting a ton of money out of those conversations. 

My plan is to take the next six months to try and learn as much as possible about multifamily real estate, while also saving up money to be able to start a career in brokerage.

If you have 20k set a side keep in mind you may need to dip into that money if the seller won't deliver is POS complaint.

You use $50k of the loan to do the repairs.If you have 20% down + rehab money, then you can do a FNMA HomeStyle program.The FHA 203(k) is a great BRRR tool. 

But do look at the shiny penny and spend big sums of money to learn.

I wouldn't care who buys my property, I want to net the most amount of money in the shortest amount of time.

I want enough money coming in so the business can sustain itself when issues occur with maintenance or vacancy.If you wanted to do this with only 20% down ($46,000), which is all you need for a conventional loan, here is how the calculations change.Total mortgage + escrow $1,493.33 per month with cashflow reduced to $306.67 per month.I prefer to overestimate purchase price, interest rates, and homeowners’ insurance to be conservative.

You can still find homes in these markets, among others, that are priced between $160k to $275k that still provide passive income, allowing your residents to pay down your mortgage, cover your other expenses and still have excess money to either save in an account for future investing or pay down your existing mortgage faster. 

Private (hard) money might help with renovation but will be pricey.

If you want higher growth then Cleveland and Dayton type markets with $100-150k prices may be better suited.I would encourage BRRRRs after your 1-2nd so you can recycle your money.
