Just take a break. If money is not an issue, keep your sub up for housing purposes or if a friend need a hand with something.

I personally took a long break during HW, at the begining of 3.1 through 3.3 because Gordias killed my will to raid and I had no faith in the next raid tier. The game was feeling really stale at the time and the Diadem was truly bad. I had plenty of things to do when I came back. It was refreshing and felt like starting over, re-learning some stuff I had for granted.

It's sad you can't transfer your house to someone else or make the house sharing more useful, like letting that people to stop the autodemolish feature by stepping inside your house.
