I will be quoting a sentence from another great BP member @Lisa Phillips that "experience is your best teacher" because you will use different handymen and after using 4 or 5, you will get the best out of them. 

Hello,I'm a piano teacher that lives in Seattle looking to purchase a small multifamily building (duplex to quadraplex) as a way to stop rent from holding me back financially,  and perhaps bring in a little income someday.

For the past eleven years, I've been a high school science teacher, but because of the ever increasing demands in that career, I decided to switch.

I bought my first rental in graduate school at 23 (it was seller financed, although I could easily make the payments I doubt a bank would've ever approved me for a mortgage at that point as a bartender and Teachers assistant). 

@Brandon TurnerYou and David are great teachers.

However, I plan to be a teacher next year.

so you could get either  teachers/ nurses/ people that want to be closer to work or the town to fill your units and stay longer term than students so it would really be up to how you screen your tenants and what you setup.

My advice to you is action is your best teacher.

Chad is a good guy and natural teacher. 

Then, how to make the numbers work on my teacher salary.
