How Property Butler Values Properties

IGR-Registered Transaction Data

We analyze 100,000+ properties across 6,900+ buildings in Mumbai using data from the Inspector General of Registration (IGR) Maharashtra. Every transaction is a verified, government-recorded sale deed — not an inflated listing price.

  • Comparable base rates: median PSF in your building
  • Floor proximity matching: higher floors command premium
  • Furnishing, possession status, and facing adjustments
  • Developer branding premium (10-20% for top developers)
  • Locality negotiation dynamics and recent market trends

Frequently Asked Questions

How does Property Butler calculate valuations?▾
We analyze registered sale transactions from IGR Maharashtra. Our algorithm compares your property against 100K+ properties, adjusting for floor, area, furnishing, age, and market trends.
Why is IGR data more reliable than listing prices?▾
IGR data is government-verified sale deeds — actual completed transactions. Listing prices on portals are often aspirational. Our valuations reflect real deals.
What does confidence level mean?▾
Confidence reflects data availability: High = 10+ comparables, Medium = 3-9, Low = under 3. More comparable sales = more reliable estimate.
Can I use this for a bank loan or stamp duty?▾
This is a market intelligence estimate, not an official valuation. For stamp duty, use government Ready Reckoner rates. For loans, banks do their own appraisals.
How recent is the transaction data?▾
We analyze sales from the past 24 months. Transaction dates are shown for full transparency. Data is refreshed monthly from IGR records.
Does this work for rental properties?▾
Yes. For rentals, we use active rental inventory data showing estimated monthly rent and gross rental yield based on comparable leases.

Valuations are estimates based on comparable transaction analysis. Actual value depends on condition, negotiation, and market cycles. Not financial advice or a bank appraisal.
