I've completed the continuing ed classes in physical classrooms and online, and online just seemed so much more efficient.

The agent can continue to represent the Seller, and the Buyer would be unrepresented, similarly to how a FSBO represents themselves in a transaction with a Buyer who has a Realtor. 

This has been a tremendous help to my bottom line and I expect to be able to continue this with all my personal holdings.

I can afford to keep the condo and continue to take a $458 to $383 monthly loss, but should I?

If you can find more deals like this or whatever meets your investment criteria, and want to continue to add properties, it makes sense to leverage up a bit and hoard cash.

(sort of... maybe.... still digging....)I document my journey as I continue learning more about commercial real estate world of multi family investment/ownership so feel free to check out my site. 

Whether that means buying a condo/townhome or continuing to rent while saving for a sfh.

Maybe you could ask to be kept in the loop as those referrals continue to move through. 

However, that "family funding" is not going to last forever and I am eager to find a way I can continue to fund my deals without the help of my parents.

Education is great, and it's vital, but you'll learn much more once you start taking action, and if you are open to continuing to learn, you'll do well.
