Simulate paying the same amount (let's say $3,000) each month toward just your mortgage vs. funneling it through a HELOC.

I have been trying to simulate different scenarios by buying property with 20% down and none of them show a positive or not even close to be breakeven.I'm willing to invest in different states but all this is new to me and it's complicated.Thank you.
