We plan on selling our current home in a year or so and upon doing inspections to find possible flaws or common problems that will need to be addressed to help sell the home I noticed a drywall crack extending from the top corner of a room opening to the edge of the second level floor in an open foyer (open from lower level to upper level). This crack is visible in the drywall and looks bad and I would like to get rid of it to keep it from being an issue with a home inspector or potential buyer. The home is about
4 to 5 years old.Any ideas on how to eliminate this crack, most likely caused due to some settling, without causing some major problems to the drywall. The crack extends at about a 45 degree angle, upwards, and about for 18 inches.
