I would definitely go ahead and get your license. 

@Amy Summer welcome and congrats on thinking this far ahead!

The most obvious one, of course, is that the buyer can go ahead with their investment plans even if they do not have funds set aside for the down payment.Another significant advantage is that the buyer can save on traditional bank closing costs, which often range from 2%-5% of the purchase price.From the seller’s perspective, this financing mechanism will make it easier to make a sale in difficult market conditions.

If you have $1M sitting around in the bank, great for you, but don't rush to spend/invest it without doing your due diligence — good luck! 

there's no need to rush. 

I need to go ahead and talk with the sellers to be first in line if they get crickets at their asking price.

In addition, there has been a rush of investors and owners converting their homes and rentals into STRs, so there is bound to be an oversupply at some point.

If it turns out to be nothing more than tripped breakers, the charge for the service call and the PM's time will be charged to the renter ahead of next months rent--meaning her payment will be applied to this before its applied to rent.

If not, you are probably leaving a lot of money on the table.To truly get ahead going the self-management route, you need TIE. 

While you don't want to rush into a decision on buying a rental, it's not very hard to buy one, so you don't want to over analyze.
