There are many syndicators that had built a reputation for having executed business plans, very communicative, and accountable.  

@Michael SmythiesThe biggest lesson is the wild and ever changing landlord tenant laws.To your area of interest:- Tenant relations: Keep it business, stick to the lease agreement, communicate, and the golden rule.

Our checkout time is 10am and we communicate this to them in the House Rules, check-in message, day before checkout message, rental agreement, and on a list of rules on the back of the front door.At 10:15am we send them an message asking if they have checked out because our cleaner contacted us and is waiting to get inside.  

Communication - Text, email and phone.

She wants to be emotional and she wants to be dramatic.

so I called VRBo as something doesn’t feel right, they said no one from VRBo called today, and they gave me his email address to communicate with him.

Some properties are not worth keeping, even though person can become emotionally attached to them.

Communication with the loan officer is not the greatest. 

Conversely, I also know people who find communicating with guests and cleaners to be incredibly draining, they don't know the first thing about managing an STR nor does it particularly interest them, and they would rather spend their time making money in their main job rather than taking on a side hustle that they may not be able to do as effectively.

It will help keep you organized, streamline your communications about the repair both to the tenant and to whatever trade person you use to do the work and make your bookkeeping related to the repair easy.
