GOOD TO KNOW

Other questions? Contact customer service.

How is AI valuation different from a valuation report?

AI valuation gives a quick price reference for homes and land. Valuation and survey reports go further, covering rights, area conditions, comparables and analysis. Choose by home, land, urban renewal, rebuild or claim case.

How long does a valuation take?

According to the app, a mobile valuation summary usually takes about 20 seconds and a professional report about 10 minutes. Actual time depends on the property, data completeness, transcript requests and system load.

What is the difference between transcript search and transcript requests?

A transcript request obtains a transcript by address, building number or lot number. Transcript search finds and organizes transcripts you already requested, with notes and lists for case work. Stored transcripts reflect the time they were requested, so check the latest land records for current rights.

How do I register and use paid services?

MyGoBigData is membership based. After registering and verifying, you use services with points. Check point costs and request fees on the official platform. Companies and heavy users can ask customer service about plans.

What can experts help with?

Experts can answer land administration, urban planning, building and deal questions, such as how to read rights data or what to check before developing or rebuilding. Service format, times and scope follow the platform or customer service.
