Managing properties remote

[J Bess]

I've been lucky in that since investing in real estate I've been able to get a new property every six months. The goal is to have enough passive income where I can semi retire elsewhere in the country. I hate the idea of giving away 10% to a property manager. I hear stories about people managing properties from a far. 

How do you do it? Specifically around showing the property or cleaning between tenants?
