Reference Sources & Government Data

Sapkhumka uses authoritative government and market-data sources as supplementary references for analysis — not as a substitute for actual market prices.

⚠️ Important — read before relying on reference data

Government appraisal prices can differ significantly from actual market prices (especially in central business districts and speculative areas). Appraisal figures are used for reference and to filter "below-appraisal" listings only. Always verify market price and area liquidity before deciding.

🏛

Appraisal

Treasury Department — Property Appraisal Search

Official appraisal prices for land, condo units, and buildings. Used as a reference figure — not the actual market price.

How we use it: Shown alongside listing prices so investors can see the gap between appraisal and market, and filter "below appraisal" listings.

📊

Market Index

REIC — Real Estate Information Center (Government Housing Bank)

Official real-estate market indices and reports — Composite Property Index, Housing Price Index, Raw Land Price Index, and more.

How we use it: Quarterly index figures shown on the Market Data page to compare macro trends against individual property prices in our system.

Auction

Legal Execution Department — Auction Property Search

Search the official auction listings (land, houses, condos) registered with the Legal Execution Department — feeds our "Auction" category.

How we use it: Auction listings are sourced with attribution back to the LED (source_type = auction). Users can click through to verify on the official site.

How we use this data (methodology)

Government data complements lister-supplied information — it does not replace the seller/agent's stated market price.
Every listing carries explicit "source" and "data-use license status" fields, clickable on the property detail page.
Market indices on the Market Data page are real figures from the source (REIC), recorded quarterly by an admin with citation links.
Value-analysis figures (Yield, ROI, scores) are computed from the user-entered inputs — not from government numbers.

Property scoring methodology (5 dimensions)

Sapkhumka scores each property across 5 separate dimensions, combined into an overall "Value Score /10". The formula is open and reproducible; missing data is filled with a neutral midpoint so listings aren't unfairly penalized for incomplete inputs.

Location

30%

Distance to mass transit, main road, hospital, and school — each scores 0–2.5 based on the kilometers entered by the lister (total 0–10).

Price

25%

Gap between asking price and the government appraisal (Treasury) or market price. The further below appraisal, the higher the score (≥20% below = 10). Rentals use a neutral midpoint.

Yield

20%

Gross rental yield (expected rent × 12 ÷ asking price × 100) — ≥8%/yr = 10, ≥5%/yr = 7.5, etc. Rentals use a neutral midpoint.

Condition

15%

Building age (from year_built), "ready to move-in" status, presence of usable area, and real photos — newer and more complete listings score higher.

Risk

10%

Verification status, public-data/partner sourcing, license-status, and competition density in the same district — verified listings with less competition score lower risk.

Known limitations: Scores rely on system data only. External factors not yet included: flood risk, mortgage encumbrances, true market liquidity, and after-tax net value. Always conduct additional due diligence before investing. The formula may evolve as data quality improves.
