Proposed Feature

Support immobilie-kaufen as the combined wohnung & haus real estate type

Alternatives Considered

Using multiple providers, one for house, one for apartment.

Benefits

Would cut the number of providers in half when a user is open to both apartments and houses

Additional Context

Example search URL:

It seems like they do not offer the same filter in the mobile app. If this is true, I can obviously not translate the request. Can you check please if you find it in the app?
