However, I am seeking recommendations for the most effective tools and software for remotely managing my Airbnb properties, as I will not have a local short-term rental manager.Specifically, I am looking for software that can assist with property listing, pricing optimization, channel management, guest communication, and any other relevant aspects of property management.

Estoppel letters are signed by each tenant and counter-signed by the owner as true and correct.

We would handle the guest communication, coordinating cleaning, minor repairs, stocking supplies, calendar management, etc.

If I'm wrong I'm sure someone will correct me. 

The 500-hour rule means spending at least 500 hours actively managing your rental property, which could include things like tenant communication, maintenance, and bookkeeping.You can also group multiple properties together as one “activity” to make reaching the hours easier.

Are there ways to address this concern or to communicate the value of these unique features to the appraiser effectively—without overstepping?

He is interested in the deal but has been dragging his feet and finding it hard to get on the phone to talk to and communicate with.

Hey @Andres Triveno, this is always a loaded question and there are different answers.I agree that most often what @John Underwood and @Collin Hays said is correct.

Their argument, if I understand it correctly, is that I have two buildings on the property.

DMs are a great way to communicate on the site, but you can judge the tenor based on when you received the DM.
