It took a long time for me. I mean, like, six years. This wasn't my "dream house"...but not much was available when we were looking---so we took it.
It is a nice house in very good condition in a great neighborhood. However, the family before us had lost a child while living in the house (at a hospital, but still...there seemed to be so much sadness for them here). It just didn't feel like a "happy house".
We changed some flooring and paint colors, finished the basement, changed the shutters/door color. However, it didn't really feel like it was our HOME until we had lived here longer than the previous owners. Also, when we first moved here, we would always go away for the major holidays (to visit my parents for Christmas and Easter). They moved to our town a few years ago and now we celebrate holidays in our home. Also, as our kids get older, they have their own little friends running in and out all of the time.
I think building these memories also have helped make it feel like HOME.
