Will the rents you get in cover the mortgage plus expenses (portion set aside for future repairs or cap-ex, maintenance, insurance, taxes) *and* produce cash flow? 

Just make sure you are getting excellent value of you are giving up a significant portion of you commission.

Is it better to pay extra toward your principal portion of your mortgage per month OR is it better to save for your next rental property?

Would my downpayment include a portion of the CC?

It’s vital to keep it fun and interesting.

My team and I are curious about building from the ground up you seem like you have some vital information and expertise on the topic

There are two things to consider with that:  1) if you decide to sell it, and have shown your house as partially rented on your taxes (which you should), then capital gains tax will come into play on the rented portion.  2) For your next purchase, unless you have a lease in place for the whole home, you will have a hard time purchasing a multi-family as your next live in flip.  

I've been talking about it for a good while now, but never initiated to start gathering vital information until now.

but garnishment only gets you back a portion of the money after all of the fees, and payments come at a slow drip.  

My experience is a small portion of buyers 10% or so will be just turned off since it will be disclosed, another 10% or so will try to think since it was there you should accept a lower price, but the other 80% don't care since it's now fixed and they have the warranty.
