You probably went with the Austin-Round Rock metropolitan statistical area to choose which zip codes to display, but as you build out this and future city models I think it would be worth considering surrounding zip codes as well.

My question is more in terms om how do I actually collect this from guests via Airbnb (since they dont collect automatically to your point) and I am afraid they may be penalising me for collecting surplus tax in how they display bookings. 

It is only applicable for first year of ownershiphttps://singlefamily.fanniemae.com/media/4051/display

I was going to post a rental on Zillow group (Zillow, Trulia, Hotpads) but it seems like they display a public record of previous rental listings (including date and pricing) for every property, which I really don't like.

This may be a result of HUD not displaying the appraised value anymore on HUD Homestore.

I also have some of the soloK funds invested in cryptocurrencies, a few stocks thru Schwab (mostly Canadian cannabis), and some gold coins stored in a safe deposit box with our bank. 

Without pilfering through the numbers you displayed in great detail I can say this:Find out what the Property After Repair Value is (be conservative, tight comps)The exit strategy for yourself or anyone who you could wholesale this to depends on how the Property is Performing, or how it could perform. 

And, when a listing agent displays 35 photos, why go and see it? 

Knowing this I believe the property management companies that can hold themselves with integrity, display it through transparency and communication and even go the extra mile to guide clients to an option which isn't as financially beneficial for them are the ones that will inevitably be the most successful in the long run. 

At the time I was at Home Depot looking at their kitchen cabinet displays.
