I don't have an
Office in my Home . . . .
I just live in the Office:

My Office occupies about 600SF towards the North End of the Dwelling with its own small WashRoom; pretty well isolated from the rest of the House. A Licensee is here 168 Hours per Week. I'm on a Numbered Highway and can easily be found. I'm out in the Boonies, and after 14 years doing this here, would never consider going somewhere else to work.
I think Henry Ford said
"To Sell a Ford, you have to Drive a Ford". I Sell the Boonies; so I feel I have to look/live like I know what I'm Selling !
I chopped a New Door into this Old (1834) House to make sure people could enter the Office without feeling they were entering thru someone's Living Quarters; and there's plenty of Parking near the Office Entry. And the Office Windows provide ample views of the Valley, WildLife and Mountains beyond.
Our Marquee along the Road changes twice a week, and there's always a different Property rotating from the North and South faces. Those are 4" Letters (legible at 100' @50MPH). It works at advertising 24/7 . . . . For Free !
Having a Home Office also demands that you eliminate any other distractions in the Environment like . . . . Pets; Children; Noises; Cooking Odors (or other less appealing smells); or any evidence of Hobbies or other activities un-related to Real Estate.
If you create an Office now; you must also comply with the ADA. Also, being so Public, I just hate it when people stop by and pretend to be Real Estate Customers . . . . but
They really just wanted to use the WashRoom !But, that comes with the Territory; they're only Human Beans!
