If you can get away with that, great, but it is nice to have someplace official to go if you need to meet with colleagues, vendors or customers from time to time. A real estate agency I work with closed their dedicated offices, remoted all of their remaining agents and has a small office in a shared workspace building. They can book conference room, use a common kitchen, the restrooms are maintained and other services are available on a contracted basis such as reception, phone answering, etc. Only the office manager comes in and not even regularly. The estate agents can meet people in the field but it's sort of awkward to have people coming to your home to sign contracts, etc. Security is also an issue. My published address is my PO Box. I don't advertise where I live as a self-employed person. I don't want to show up on Google Maps with a big pin that screams "a bunch of expensive stuff can be had here".
