"Hus" seems weirdly pronounced. It's like instead of pronouncing the "h" they pronounce a "d" or something. In other recordings I notice the voice rarely pronounces the "h".
That means "does his house sell?" which doesn't make much sense. You could write,
- Selger han huset sitt? which means "is he selling his house?"
- Selger han huset hans? means "is he selling his (some other man's) house?"
