You'll want a property manager.

Managing units is work.  

I guess it can save you some time managing, for example one tax bill, one insurance bill. 

First, Are you licensed and insured to manage other people's properties?

-Management is low - you'll need at least 10% plus leasing costs - typically a month's rent for each lease-up, and sometimes a renewal fee as well-Insurance seems low-Are taxes accurate? 

As an owner you're allowed to manage your own properties.  

I’ve been looking into areas like Oakhurst, Mariposa, Yosemite West, and surrounding towns.If you own or manage a vacation rental in this region, I’d love to hear about your experience.

I always remind myself that it isn't personal and that I chose to sign up for exactly this kind of work (managing difficult tenants).

One of my clients just bought a bizz ( new bizz for him) and the owner stayed on and they are running it together.. its manufacturing and I suspect that more prevalent than RE development.

Making sure we can manage our own properties in these areas.
