"D.O.M." stands for "Days of Market." It is a real estate term used to indicate the number of days a property has been listed on the market before it is sold or taken off the market. The combination of "🔒🏠👨" in relation to "D.O.M." could suggest that the description is about securing a home and the involvement of a person, possibly a homeowner or a real estate agent, in managing the process.
