Real Estate Time Machine
See how one housing decision might have looked with a city, a buy year, and a simple apartment size.
How this tool works
This module uses the uploaded real_estate_data.csv file as the runtime source of city-level price-per-square-meter estimates. It is educational context, not a property appraisal.
Common questions about this real-estate what-if calculator.
Frequently asked questions
What does this real-estate tool estimate?
It estimates a city-level purchase cost for a chosen year and apartment size, then compares it with the latest year available in the uploaded dataset.
Is this a real property appraisal?
No. It is an educational city-level estimate based on price-per-square-meter history, not a listing-specific appraisal or mortgage quote.
Why can two homes in the same city differ so much?
Actual property prices vary by neighborhood, building age, quality, and exact unit features. This tool is intentionally a broad city-level comparison.
What dataset does the page use?
This phase uses the uploaded real_estate_data.csv file as the canonical runtime dataset for the API and page.
