So many things wrong with all this.First don't pay for this.

Got an equity line of credit and borrowed from it to pay cash for the property.

He pays seller's note ("outside" loan), and then the seller turns around and pays his loan ("inside" loan).

@Jordyn Ohs pay off/down your Heloc aggressively and/or look into DSCR loans for future acquisitions.

Always have a plan to pay it off quickly and free up the credit line for your next deal.Regarding pulling equity from your first property to fund the second one, this usually doesn’t make sense in the early stages.

This seems unlikely in the long run. you are forgetting that someone is paying down your principal for you so you need to take that into consideration. 

Went on to purchase additional rentals so tenants can pay down the loan and I build equity How did you find this deal and how did you negotiate it?

The current renter is paying 2600 for the whole house, but when fixed up a bit, the upstairs could likely fetch 2700 and the basement could probably get 12 or 1300.

Hire a college students/or architect from other countries who can do 3d rendering at a very affordable rate (I pay $200 for 4 first time super realistic 3D renderings of the exterior, repeats are even cheaper) and do a number of elevation studies before you down select your exterior paint and finishes.  

If this is what sub2 is, then why are people paying tens of thousands of dollars to learn this process?
