vacancy, repairs, capex, management, any shared utilities, any groundskeeping not done by the tenants, any permits or registration fees, etc. 

Build a team:- Commercial RE Agent- Lender- Contractor (for any updates/repairs you'd like to do)- Insurance Agent

I guess my question to you all is, where have you had the best luck in finding contractors for your projects, specifically in Arizona’s market?

I would to connect with lenders, contractors of any kind, investors and insurance agents. 

I even was able to attract better contractors once the projects were in nicer neighborhoods - all thanks to other people's money.I guess I never looked at the cost of the money (fees/interest) as a negative, since I realized that in order to experience growth, capital would be necessary.

If I was starting out, and lived in the area, I'd be hammering tomorrow..If you're hiring contractors forget it.

I have been working with a wholesale brokerage here in Houston and I am an independent contractor for them and I Dispo all of their deals.

I currently have a very stable software engineer position and eventually hope to cut back hours or become a contractor that works 20 hours per week once I am able to hit some of my financial goals.The ADU seems like a potential way to keep my mortgage expenses down since I would just pay for it up front with the sell of the property.

A professional may often do a better job when it comes to hard decisions as it's just business to them.A DIY landlord though, may babysit their tenants a search high & low for the cheapest contractor and then pay them cash to get an even better price.- A PMC is not going to go to the extremes owners do as a PMC can only afford to spend X amount of time on problems for owners - or go out of business.

I've met contractors, partners, investros, lenders etc all at the meetups.
