Is it possible to add an external ADU on the property? 

I have kept a ton of fish and the external pumps can leak.

In Denver where I invest it's actually a PLUS to not have the other unit considered separate because permits are only allowed for STR if you're renting out your primary residence and I know many folks who put a locking door on part of their home and have a separate external entrance to that part of the house, and rent it out as an AirBNB without it being considered an additional unit by the city.

Zillow won't let you post any external links in the listing, but I send them a copy of the video in that message as well.

External is usually where they want to approve the color of the house, types of materials, roofing, landscaping, driveway condition, etc.

From an outside viewer, I would be nervous to work with either one of you, since you are fast to go public with any grievance and the realtor has poor communication skills and has no problem blaming external circumstances for lack of a simple courtesy call.

Also, I would recommend using an agent to provide you with handpicked comps that are similar to this property in this neighborhood to justify the value.

Quicker build times, no external factors (weather), precise details.
