Brittany Murphy's house -- the one in which she died -- is no longer for sale ... and it's all because her mom felt uncomfortable showing the property with Brittany's stuff still inside, this according to Brittany's widower Simon Monjack.
Brittany's 8,000 sq. ft. Hollywood Hills home -- held in a trust controlled by her mom, Sharon -- went up for sale in March for $7.25 million ... a decision Monjack now says was made in haste.
Simon tells TMZ Sharon decided it was inappropriate to show the house to potential buyers while her daughter's stuff was around.
Simon says he doesn't know if or when the house will be put back up for sale.
