The house is finally finished and is beautiful. Anna and Max didn't sleep together, Max made it up so Anna would come back to him. Anna tells Walter this, and they kiss and make up. They get married and live in the new house. The lady who sold the house turns out to be a con artist, and sells a house in Rio de Janiero to Walter's dad and new stepmom.
Continuity mistake: When Walter is watching the fire go through the electrical system in the walls of the kitchen, watch the blender. One shot shows thick, chunky, white/orange stuff flowing out over the edge of the counter. The very next shot shows the blender toppled, but very clean. There is no trace of the chunky stuff in the blender or on the counter.
