To use the SellHouse command you must be in the Player House you wish to sell.
There must be an appropriate CityNet terminal/computer in the
Room
with you, or
Held
in your hand.
And - we know this is a radical concept - you must be the current owner of the
house. Duh.
If all the conditions are met, a Web window pops open in which you can enter
your sale price. If the house is already listed for sale, you can use this
same mechanism to change the sale price. If you want
to withdraw an already listed house from the market, enter 0.
The popup window will then show you the real estate listing page, to confirm
your new or altered listing.
NOTE that nothing is done automatically with your
access control list. If you don't clear it before the sale, the buyer inherits
it. Is that what they want? Up to them to deal with it, or not.
