Meaning either EVERYONE is breaking the law, or more likely, the zoning displayed on Redfin is inaccurate or refers to something else semantically, like “No STR” means no hotel / motel buildings allowed to build on this land but a 4plex that can be used as an STR is permitted?

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.

Muffler shops, car washes, Fire work stands, Insurance offices, Medical plazas, daycare buildings, etc. 

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

So they set all of the gold cars they saw in the parking lot on fire.No caption necessary for this toilet from hell.This is what a kitchen can look like when a low income tenant moves out of it.This is what a backyard can look like when a low income tenant moves out of it.If tenants in these tough neighborhoods don't have yards, don't worry they will light off their fourth of July fireworks in their bathrooms.Don't worry though.

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?
