21 years ago I decided that I didn't want Property Management to a full-time job even though I was going to self-manage each property.Now I have 28 apts with 60 or so tenants in 8 multi-family buildings in Brooklyn, NYC.I use a LOT of technology including electronic rent collection, electronic locks, internet controlled Thermostats, WiFi Cameras, Cloud Based CRM, Electronic Signatures (DocuSign), automated expense payments, etc.

I was thinking things like maybe a Nest thermostat or Ring doorbell -- something that is a few hundred dollars but that most houses won't have and will give me an edge over the competition.
