About this app

Rayic is not a government agency or an official body. It does not represent, and is not affiliated with or endorsed by, any public authority.

Rayic estimates a home's market value and risks from its address. Get to know a home from every angle before you buy, rent or sell.

FREE VALUATION
• Estimated market value and expected price range
• Estimated monthly rent, annual rental yield and payback period
• How the asking price compares with the market value
• Zoning of the parcel: land use, building layout, height limit
• Location and surroundings, 3D building model, sunlight analysis and drone video

REPORTS
• Earthquake Risk Report: the building's damage probabilities, ground and shaking, earthquake simulator
• Crime and Safety Report: crime records nearby, the district's rank in its province and an incident map
• School Quality Report: schools nearby, walking times and the area's education quality
• Urban Transformation Report: the owner's share, your apartment after redevelopment and the change in value

NEIGHBORHOOD MONITOR
New crime records and school rating changes around your homes arrive as a notification every month.

FIND YOUR NEIGHBORHOOD
