My House has gone because of the map changes that have been made to Gtm#1 its worth $500k and the Id for the home is 224, my home which was located near the Military base, is now gone but when I go onto the phone and try teleporting to my home it teleports me on top of a new home which isn't mine..
I'm pretty sure they would have told you to move out prior to its removal. You can make a support ticket here.
The house you own was being removed and there was a sign posted on its door for a long while. This sign told you when it was being removed and to move your items and sell the house. Have a nice day!
