Private sale
Fewer people. Same accuracy.
No lawn sign. No broad public campaign. Showings by appointment. It is still a real sale, with a lawyer and a written agreement.
Private sales suit owners who do not want a brochure on the street, families in a dispute, estates that need dignity, and higher-value homes where a public price history changes the next negotiation. They also suit enforcement files, where spectacle can cost more than it attracts.
Private does not mean secret from the people who must consent. A spouse on title, a lender who must discharge, and the lawyer who must close are part of the sale. See coordinated sale.
A quiet sale is not a licence to hide a defect. Commission is still negotiable and agreed in writing before marketing starts. If the reason for privacy is a notice, combine this with selling during a power of sale.
