EstateViewer is a descriptive combination rather than a name that needs an invented origin. A property-focused project might use Room notes and viewing records as its companion line. A presentation application could instead emphasize Property images in context. Because estate can also refer to assets beyond buildings, the opening page should make the chosen subject obvious. If the scope is residential interiors, say so directly. The name can leave room for later development without requiring the first publication to cover land, commercial premises and every kind of property transaction.
