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.

Zelle and Venmo-  Pro's:  Super simple. 

Second position DSCR does exist but rates are even worse than HELOANs, I'd expect 11-13% right now.Getting a simple cash out refinance sounds like the simplest option, but if you can just get a large first position HELOC only that would be a pretty convenience deal.

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

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.

Very simple to do.1) In the hole you, spray some suspend sc insecticide inside the hole. https://www.amazon.com/Suspend-Insecticide-USA-Supply-Eradic...2) Get a beekeeper suit, just in casehttps://www.amazon.com/Professional-Ventilated-Sheepskin-Bee...3) cut open the area.4) Spray inside the entire wall the suspend SC5) Dry out and close up the wall.If this cost you $200 and some time, I'd be amazed. 

In many jurisdictions any lease 24 months and longer basically conveys additional rights and a simple eviction is no longer feasible. 

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