Luckily I am starting out with almost all of those boxes checked off already, however I am considering possibly making the bathroom a little bigger since the shower is at best 30x25" and the toilet is in this little nook that is raised up on a small platform (i'm sure its because the main line to the sewer is on the other side of the house).

Do you use cozy or another PM platform to onboard tenants and manage property?

I just use an online platform to collect rents automatically. 

Just a heads up that if you do reach out to too many hosts Airbnb will flag it and you run the risk of being kicked off the platform.

You have someone build the deck/platform, assemble the kit, etc.

I'm not saying Propertyware is the best and I do have plans on switching in the future as I grow but I do feel 2 platforms are needed to separate my management business from my total personal business.

Promote your listing using online platforms, social media, and Airbnb's own tools.
