The owner had her own listing set up on VRBO and has given me the username/PW to be logged in and responding to inquiries and managing guest communications.

My business has access to AppFolio, but it doesn't seem to communicate with the STR side of things. 

Additionally, those forced to relocate due to the fires should update their address with the IRS to ensure they continue to receive relevant communications.

It’s a smart move, especially since it ties in with your goal of saving for your first investment.For skills, you probably already have a good foundation with your sales experience—things like communication, organization, and dealing with clients are all super valuable.

I agree with @Michael Smythe that you need a property manager that communicates well. 

You manage the headache of guests and communication, cleaning, etc. and he provides the property, but shares in the expenses and profits.

So, communication and assignment issues, as well as not being able to explain the maintenance issues and the required work.3) Proper documentation and quality of work issues.

I tried to work with my tenant but they cut off all communication with me and wont respond to anyone.

Poor communicators, poor housekeeping skills, prescription med abuse, big dogs that they couldn't properly care for, damaging, etc.

Make sure the previous property management company did their job and communicated a change in management prior to you taking over--along with your contact information.If they have no done this, they should so the tenant doesn't feel like a scam may be going on.Just make sure they're away of where rent payments need to go and who they can contact in the future.
