As they are getting paid to provide a service.

Ideally you can provide something extra or unique that you can highlight in your photos and description to stand out. 

I will provide an update when I hear back or have substantial resolution to my issues.

Based on the numbers you provided, these are well above the debt service coverage ratio of 1.25 hence from a lenders perspective, this is loanable.

My point is this, I am actively involved/advising this investor, providing local vendors contacts (handyperson, surveyor, painters, etc) and I "don't wait for them to call me", I call them weekly. 

Providing superior service, cheaply.

I’m looking for a local mentor that I can learn from and provide value to so any suggestions on how to find one and pitch myself would be great as well!

I used a property manager (before I was one) for (1) time & headache savings and (2) the value the property managers provide by economies of scale (marketing, discounts with vendors, etc.).

I have provided them a letter from my broker about the amount that can be used.

If the guest feels slighted, there is no fact checking service provided by AirBnB to confirm their claims, so it is up to you to let future guests know the level of professionalism you provide.If you are able, I would recommend editing your response to the 1-star review.
