But the math doesn’t seem to work at all.

Math...with $$$$ in front, and not %%%% behind. 

Kind of like appraisals one surveyor is doing their math one way and it does not match anothers.. also depends on where their controls are .. do they have to go half a mile away to find a control point to then measure back in..   

I’ve done some serious homework on the first property (triplex) I’m looking to buy.

Be sure when you are mathing out your next purchase, you include the cost of the HELOC. 

Do your math and maybe save $20 or so like I could have. 6) You will be nervous and wishing to pass out.

In the end, if you do the math right and you are putting it on top, it would be better than losing time and potential money to interest payments if you have a loan. 

YES its this simple.Hey all, I see so many posts, " I am researching, " I am doing my homework" , I am trying to build my team" "Deciding on which area" So many are TRYING but never do anything, like a hamster on a wheel, A LOT of movement but staying in the same place.

with that said, i totally agree with you that trying to math your way to a market makes no sense.

It's important to do your homework and think about your personal risk tolerance and long-term goals.Good luck!
