I think I got the idea how to do it by reading a similar question in the forum. First move your stuff back into inventory. Then if using Phoenix, Go to World/About Land/Abandon Land.
Then, search for an appropriate house and buy it and move your stuff back into the new house, this will take a while, you can redecorate too.I am looking for a nice location to move to. SL is like RL almost. in RL I changed over 19 houses since I was born!
