BOOUP is a real estate data app that allows you to quickly check actual transaction prices for apartments in Seoul, Incheon, and Gyeonggi, and calculate acquisition tax, capital gains tax, and even taxes for upgrading to a new home for reference.

It was created not as a service you search once and stop at, but for a "data routine" where you save complexes of interest, ensure you don't miss price changes, and continue managing them.

■ Suitable for:

· Those who want to study real estate and check market price trends firsthand

· Single-home owners preparing to move for actual residence

· Those considering selling their existing home and moving to a new one

· Those who want to set a realistic budget by calculating taxes and incidental costs in advance

■ View Actual Transaction Price Data

· View Jeonse / Sale transactions by region

· Filter by Seoul, Incheon, Gyeonggi → City/County/District → Dong

· Filter by type (e.g., 59㎡, 84㎡), select period, and sort (Latest Transaction Date, Recent Transaction Price, Record High)

· View Type, Model, Record High, Recent Transaction Price, Transaction Date, Floor, Direction, and Location at a glance

· Understand market trends through price history by complex

■ Save Interest Complexes & Price Change Notifications

· Save interest complexes to the app so you don't have to search again

· Quickly check notifications when prices change in saved complexes

· If you find a good candidate, don't stop on the web; save it to the app to continue managing it

■ Tax Calculator for Reference

· Purchase Calculation: Acquisition Incidental Taxes (Acquisition Tax, Local Education Tax, etc.) + Total Acquisition Costs

· Sale Calculation: Capital Gains Tax, Capital Gains Tax, Local Income Tax + Net Selling Amount

· Switching (Sell and Buy): Net Inflow after Sale and Total Cost of New Purchase at Once

· Enter Conditions such as Designated Adjustment Area, 1 Household 1 Home, First-Time Homebuyer, and Holding/Actual Residence Period

※ Calculation results are estimates for reference only. Actual tax amounts may vary depending on ownership type and the application of special provisions. Consulting a tax professional is recommended for an accurate assessment.

■ Export to Excel

· Export search results with current filters applied as an Excel (.xlsx) file

· Continue market price comparisons and additional analysis outside the app

BOOUP helps you develop a habit of "checking before you miss out" on real estate data.

From price changes in complexes of interest to reference tax calculations and data export,

conveniently manage the information you need to check repeatedly right within the app.

※ BOOUP is a tool that provides real estate data lookups and reference calculations;
