For electronically signed leases, I use Zillow Rentals (free) and Tenant Cloud for listing/background checks. 

Avail, apartments.com, cozy.co (now apartments.com), something cloud?

Tenant cloud is probably the cheapest option out there.

A few years back, I was asked by Airbnb to take part in a worldwide hosting study and, as a result, they shared the conclusions with me.

It's rather informal as of now, but I forsee it picking up more steam this year.Peers consist of 0~50+ unit property owners ranging from SFH's, 12-Plex Multifamily, Mixed-Use commercial, and so on.I intend to host our next meeting in Garrison as It's between Minot and Bismark, and we have the perfect building for a meetup!

Or they simply get tired of being on call with guests, 24/7 (yes, there are co-hosts and VA's, but that is another person to manage).We just took on a home that was previously owner-managed - it had tons of deferred maintenance and the calendar was 50% empty.

I'm actually hosting my Meetup this month (5/23) at the house if you are in the area and want to stop by to meet some local investors let me know. 

I help host one here and its always a great time! 

We are working on it, and a host of other features.

Hosting a website through Squarespace is relatively straight forward and cheap.
