The word "LIST" is greatly mis-used lately. To "List" your home typically means that you have engaged a real estate broker who is a dues paying member of the Multiple Listing System (MLS) thus your home becomes "Listed", in the "MLS", in the" Multiple Listing".
If you sell your house totally on your own, your house is in the "Classifieds". There are some brokers that offer to "list" your home in the MLS for a flat fee but you many times have to pay the advertising, hold open houses, get an attorney to draw up contracts etc. If you think you can do it yourself and don't mind the added liability, try it!
I can change my own oil but, I choose not to. The guys at Valvoline can do it in half the time and I don't have to get dirty. My vehicles are leased so, I also lessen my liability by having a reputable place do it for me.
