If the answer is yes, then it's a no brainer to make minimum payments on your 2.8% interest rate mortgage, and use the funds that you would have paid extra to pay it down faster, to either invest in more real estate, the market, or anywhere else where you can get a ROI > 2.8%.If the answer is no, then feel free to aggressively pay it down as fast as possible, to become debt-free faster, and just have a large amount of money in savings or to splurge with.The bottom line is that your 2.8% mortgage is GOOD debt.

Wouldn't mind becoming a millionaire from this as well....Should I hire a few ppl to scale the house flipping hustle (marketing, lead acquisition..ect)?

Pricing in DFW probably means you wont live rent free,and will have to pay your fair share of normal rent, but you also get 3 more people contributing to your loan paydown and you get to keep the appreciation.Buy hey...maybe I'm wrong....go talk to a local bank or credit union near where you live and get a term sheet from them for financing.
