I need capital and experience and this was just one way I thought to achieve it, any suggestions? 

It's not going to come easy, but if you have the right group of people with experience and net worth, it's very achievable.

If by "residential loan package" you are implying a "Mixed Use DSCR Loan" unfortunately doesn't sound like it would work since the commercial unit is larger than the residential

If your A/C unit is 10 years old, replace it.

I know the 3 BR unit is under market but he's a long time tenant and does a lot of work for me. 4.

For my 3-unit I currently use Rental Partners and Centerbeam Construction which are run by the same person.

If I moved away from home and put myself in a new town where I had no connections and nothing to rely on but my own resources and skills, would that help me achieve a level of wisdom that I wouldn't have gotten living with my parents? 

This experience reinforced the value of adaptability and thorough planning in achieving profitable outcomes.

This experience reinforced the value of strong communication and precise execution in achieving successful outcomes, even in fast-paced deals.

ThanksWith Tax Liens I can achieve a 16% on average.
