I guess that tipped him off that I, or someone, was coming, because the new contractor got a call from Chris.

Let me know if I can provide any additional tips or resources to help.Best regards,Sadler Surratt 

Can't say what's hardest, too many moving parts but take care of your tenants and build that goodwill, pays off in spades.

My experience with S8: There is a reasonably strong correlation between S8 tenants and tenants that do not take care of a rental property. 

I care most about the Internal Rate of Return (helps me determine how long to hold a property), the cash on cash return (helps me decide why this investment vs other options, and it also takes into consideration appreciation of the property!)

If someone was over during a high consumption month I'd give then a notice/warning for the first month along with some energy consumption tips then tack it onto the rent. 

Gotta be careful though.
