Design a real, professionally crafted mobile app icon for the App Type, using the Symbol as one centered, instantly recognizable silhouette. Apply the Style with the Colors, using a smooth two-tone gradient and a flat white glyph. Keep the house outline bold and simple, with the keyhole clearly readable at small sizes. Fill each perfectly square 1:1 canvas edge to edge, with generous padding inside the central 80 percent and no rounded corners, border, device frame, external shadow or surrounding background. Use one consistent light direction from above and no text, sparkle, glow, lens flare or photographic detail. Present the Variant as three identical square icons side by side on a plain neutral background: light, dark and tinted. Keep the symbol, scale and spacing identical across all three versions. Do not copy any existing app icon, brand logo or mascot, and include no watermark.
Use these details:
App Type: "Real estate app"
Symbol: "White house outline with a keyhole"
Style: "Gradient icon"
Colors: "Warm terracotta gradient with white"
Variant: "Light, dark and tinted"
