In reality any part of the real estate transaction can be done without an agent.
The only real value add of an agent is as an experienced consultant and negotiator.
If you have bought and sold several properties, have MLS access, know all the current vectors in the subject market and understand the contract mechanics (like when your deposit becomes in jeopardy or what repairs you can ask for), then honestly you might be better off without an agent.
Just like you don’t need to go to a nice restaurant for a gourmet meal or to a mechanic to repair your car, you really don’t need to reproduce a set of skills and experience that you already have or can go just as well without.
