At that point, he won’t receive any further compensation, and I’ll seriously consider replacing him.By the way, do you have any recommendations for good eviction lawyers?"

On one hand I don’t want to fall victim to overpriced contracts squeezing a naive owner.

If your manager is just 'keeping an eye' on things, collecting/reminding on a few rents here and there and some light cleanup while being compensated in free or reduced space rent then classifying them as 1099 subcontractor is great. 

How would you recommend, or what resources would you refer for us to properly figure out how we spend our time and appropriately get compensated for it?

I have however feel victim to some pretty steep bills for property taxes.  

I believe these systems only work if you have good employees, in which case a bonus is unnecessary.I provide strong compensation, some benefits like 401k, growth opportunities, and a strong work culture.

If you supply the machines, I recommend increasing rent $100 or so to compensate for the purchase and maintenance. 

Home warranty programs charge a trip fee every time you file a claim, and they use that fee to compensate the vendor.

@Tom Nagy It sounds more like you were the victim of a crime than that you lost money in an investment.

Offering to compensate them for their time can go a long way in maintaining a good working relationship.Let me know how I can assist further—best of luck with your project!
