A valuation report is only as strong as the verification behind it. Once it reaches your bank, the Income Tax Department, or a family court, it has to hold up on its own, long after the site visit is over. This is the checklist that goes into every land, building, and flat valuation prepared for a home loan, a capital gains computation, or an inheritance settlement in Chennai: from the first document review to the final construction-cost workup.
Everything starts with the title documents. Before anyone visits the site, the report is anchored to what the paperwork actually says:
The sale deed records what was transacted. The Patta and the FMB (Field Measurement Book) are the independent revenue and survey records that confirm what actually exists on record, so both get checked separately:
A mismatch between the deed and the Patta/FMB is exactly the kind of gap a bank, the IT Department, or a court will ask about later. Catching it here, not after the report is signed, is the point. If you want to understand what each of these documents actually is before you go looking for them, PropRef's Tamil Nadu land records guide is a useful reference.
Documents are then tested against what's actually on the ground:
The government Guideline Value from TNREGINET is checked first, but it's a stamp-duty floor, not a market valuation on its own. Market value is built from real transaction evidence around it:
For capital gains valuations as of a historical date (such as 01-04-2001), the same guideline-value and comparable-transaction steps apply, but sourced for that specific year rather than today.
If the exact year's Guideline Value isn't available, the closest available year is used, with the substitution clearly explained in the report. Transactions from the same year, the year before, and the year after are collected, weighted toward the same street and nearby comparable survey numbers, with the closest transactions to the valuation date given the most weight.
Where records are available for a constructed property:
This is the same check that surfaces building plan deviations before they become a problem for a home loan or resale. See the related guide below for what a deviation actually means for your report.
Once the land side is established, the building is valued on its own terms:
Every one of these checks becomes supporting documentation in the final report: title documents, site photographs, measurement sheets, Patta and FMB records, the EC, the Guideline Value, comparable transactions, zoning verification, and the approved plan, all annexed alongside the valuation itself. That's what makes a report defensible when it's reviewed months or years later by a bank's credit team, an assessing officer, or a court, not just accepted on first submission.
Every assignment goes through this same verification checklist before a figure is finalized, whether it's for a home loan, a capital gains filing, or an inheritance settlement.
