I honestly would not know, though at least in the U.S., "home" has an emotional and cultural context that "house" does not (e.g. the saying/song lyrics "home is where the heart is" or more objectively, a landlord owns many houses but has 1-2 homes). There is also a push to refer to people without a place to live as "unhoused" for some of the same reasons. You can have spaces, places, communities that feel like "home" and still not have a safe, consistent, reliable place to eat, sleep and keep up your hygiene. IMHO there is also the issue of who is accountable. Home is personal so homelessness might be seen as a personal challenge. Whereas house describes a structure and asset so houselessness might denote both the individual plight and the greater socioeconomic and political forces at work. At the end of the day, I suppose those most affected or most dedicated to addressing the issue should use whatever term fits.
