Is it insane to manage your own STR?

Hey friends,

Really struggling with paying 25-30% of our gross to a property manager on our first STR.

I love all the details that go into AirBNB (decor, set-up, marketing copy, customer service), so the only things I can really see needing help with are:

1. 24/7 emergency response person

2. Lawn care

3. Great cleaning people for turnovers who I can trust

Is that worth 30%? 

Our STR is in a vacation town 40 min from us - we are very familiar with the area.

High season is all summer, then slows way down.

Thoughts? What am I missing?

TIA!
