Rashi says that having tzora'as on the houses was sometimes really a bracha in the end, because the Jews found their treasures hidden by their enemies who had lived there before.

This is a beautiful Moshul for us. Our struggle is the negah that we get, and we're forced to get it all out in the open and deal with it. We need to take all our 'vessels' out of the house (reexamine all our life-habits) and break the house (our heart needs to be broken). But, as a result of that, we realize it was really a bracha all along; we discover the treasure that we had within - our potential for closeness to Hashem and to give and love for real. All we needed was that push to get it out into the open.
