Go up to the Education tab in the top menu and look for Bigger Pockets Podcast.

It has been very educational has made me really interested in passive buy and hold rentals.

I'm still educating myself.

If this is the only tenant that frequently has something "go missing", that's an issue... if many different tenants items go missing when one particular contractor does work, that's a different issue. 

I've been reading the forums, listening to podcasts, and taking in as much as possible to educate myself before taking the investment plunge.

Keep reading, posting questions on the forum and getting educated throughout the process.

It has been two years of my real estate education together with books and BP podcasts.

Do you provide move in and move out reports How many pictures do you take of the property prior to tenant moves in and after the tenant moves outDo you get weekly reports when the property is vacant what prospective tenants are saying about your homeDo you provide monthly newsletters to your tenantsDo you hold investor education classes to help me become a better investorDo you have single point portfolio based management services?

Last but not the least, A VERY good property manager who can educate you on a market, help you form a strategy, fit right into your due diligence process, and execute on a clear takeover game plan as soon as you hold title! 

I personally wouldn't swing for the fences when you are still in the education phase.
