At what point does it become too hard to do your own taxes?

[William Ring]

A bit of background, I did my taxes myself for the first time last year. It was the first time I had a salary job and/or sold some stocks, and my dad had previously done them for me while I was looking over his shoulder because he had the H&R software, I was in college, working only summer jobs, or made less than the filing requirement. I bought a primary residence that I'm house hacking and a triplex this year. My primary residence is a conventional loan and the triplex was a private loan from someone in my network (I am paying them interest). Should I get a CPA this year? What forms do I need to make sure to fill out if I do them myself? Any tips or advice would be useful!
