for sale by owner

Definition from Nolo’s Plain-English Law Dictionary

Selling your house without a real estate agent. Doing so can save you a commission but requires that you devote time and energy not only to marketing and showing the house but also to learning and following the legal rules controlling sales of real estate in your area. Commonly referred to as FSBO, pronounced "fizzbo."
