How Kanyakumari property price evidence is collected and published
Published by Kanyakumari Properties
This methodology explains how public asking prices and official guideline-value records are scoped, checked, cleaned, compared and presented without turning limited evidence into a property valuation.
A published range is evidence, not a valuation for every property.Buyers and sellers still need to match the exact street or survey number, land classification, access, approvals, extent, condition and current official record before making a decision.
Evidence hierarchy
Four price layers answer different questions
Figures are labelled by source and purpose. Combining unlike evidence into one unexplained number would hide the difference between an official reference, a seller request, a transaction and a professional opinion.
Observed asking price
The public amount requested for an identifiable property on a stated observation date. It is useful only as comparison evidence and does not prove a completed sale.
Clean and compare like with likeAgreed or completed price
A negotiated or registered figure whose relevance depends on the exact property, transaction date, parties, terms, inclusions and comparability.
One transaction is not a locality rateProperty valuation
An opinion prepared for a defined purpose using property inspection, records, comparable evidence and stated assumptions. This website does not replace that professional work.
Purpose and evidence must be clearReproducible workflow
Ten stages from raw source to published range
Each stage reduces a different source of error. If a material stage cannot be completed, the safer result is to withhold the estimate and explain why.
Define the question and scope
State the locality, property type, price unit, time period and evidence layer before collecting figures. A district question cannot be answered by one road, and land evidence cannot be mixed with a building price.
Collect traceable candidates
Record only public asking observations or official records that can be traced to a source. A copied number without a page, date or identifiable coverage is not evidence.
Capture the source and date
Store the source URL or official route, observation date, availability status and any effective date shown. This preserves the context in which the figure was observed.
Normalize the area and price
Convert every area to a common unit and derive the comparable rate from the stated total price. Keep the original values alongside the normalized calculation.
Classify the property and location
Separate land, plots, houses and apartments. Record the exact locality, road context, access, use, classification, approval context, extent and condition needed for comparison.
Collapse duplicates
Treat reposts, mirrored advertisements and repeated broker or owner entries for the same property as one observation, even when wording or photographs differ.
Exclude unsuitable records
Remove incomplete, unavailable, misleading, stale, bundled, mismatched or otherwise unreliable observations. Record the reason rather than silently changing the figure.
Compare like with like
Keep only observations sufficiently similar in micro-location, property type, scale, access, frontage, site condition, classification, approvals, utilities and building condition.
Calculate and review the range
Use sample count, median, quartiles and observed span as appropriate. Review unusually high or low results against the source instead of deleting them merely because they are inconvenient.
Publish the evidence limits
Show the range, unit, sample or record count, coverage, checked date, method and limitations. Withhold a result when the evidence cannot support a fair public summary.
Collection record
What is captured for each asking observation
A listing is not useful merely because it shows a price. The comparison record needs enough detail to identify its unit, place, property type, status and material differences.
Public source and reference
Record the page or platform, source URL where retainable and a reference that allows the observation to be checked again.
Observed date and status
Record when the offer was seen and whether it appeared current, changed, unavailable or withdrawn at the time of review.
Total asking amount
Capture the stated amount, negotiability, obvious price qualifiers and whether buildings or other assets are included.
Extent and original unit
Retain the stated area and unit before converting it to cent, square foot, ground, acre, hectare or square metre.
Property and intended use
Separate vacant land, residential plot, agricultural land, house, apartment and commercial property evidence.
Locality, road and access
Capture the narrowest supportable location, road context, legal and physical approach and surrounding use.
Classification and approvals
Note only what the public source supports. Advertising language is not treated as official proof of classification, layout or building approval.
Site, building and inclusions
Record frontage, shape, level, utilities, building age or condition and any material inclusion that affects comparability.
Cleaning rules
Retain only traceable and comparable observations
Cleaning is documented judgement, not a way to manufacture a preferred price. Each retained or excluded observation must be explainable from the stated rules.
Comparability dimensions
Properties are compared across eight material fields
- exact micro-location and surrounding use
- road width, legal access and physical approach
- property type and intended use
- extent, scale and unit of measurement
- frontage, shape, level and site condition
- land classification and approval context
- utilities, drainage and environmental exposure
- building area, age, condition and inclusions
Exclusion reasons
Eight common reasons an observation is removed
- duplicate, repost or mirror of the same property
- missing price, area or usable measurement unit
- unclear location or unidentifiable property type
- withdrawn, unavailable or materially stale offer
- suspicious bait price or internally conflicting details
- property type or use outside the defined comparison
- bundled land, building or asset price that cannot be separated
- extreme result caused by an unresolved error or material mismatch
Outliers are investigated, not automatically deleted.
An unusual price may reflect a real difference in access, extent, use, classification, approvals, condition or inclusions. It stays only when the source and comparison remain defensible. The reason for exclusion is recorded when it does not.
Asking-price publication policy
More observations allow a better summary, but never certainty
The thresholds below govern whether Kanyakumari Properties publishes an asking-price summary. They are editorial evidence rules, not statistical guarantees and not promises about a sale price.
Withhold the estimate
No asking-price estimate is published. The page should state that fewer than five clean comparable observations met the rules and avoid filling the gap with a nearby or unrelated rate.
Result: evidence unavailableLimited observed range
If the set remains coherent after duplicate, source and comparability review, publish the observed low-to-high range with its sample count, collection window and a clear limited-sample label.
Result: observed range with cautionTypical asking range
Prefer the first-to-third quartile range as the typical asking band. Show the sample count and median where useful, and identify any separately disclosed raw observed span.
Result: quartile-based summaryAsking price is not transaction price
The published figure describes reviewed public requests within a stated scope. It does not prove completed consideration, government value, bank value or professional market value.
Government guideline-value methodology
Build a range only from the declared official record set
Official guideline coverage is researched separately from asking prices. Every public summary must preserve its registration geography, official units, effective dates and limitations.
Define the official scope
State the registration district, Sub-Registrar Office, guideline village and exact street or survey route being researched.
Check the current service
Use the official TNREGINET route and record the date checked, returned unit, classification and effective date shown.
Retain the complete verified set
Include every relevant current entry in the declared scope. Do not select only the most attractive value or copy an adjacent street.
Publish minimum and maximum
Show the lowest and highest verified entries, record count, unit, check date, endpoint records and stated coverage.

A locality range is not the applicable value for every property. The user must check the exact current street or survey entry, subdivision where relevant, classification, published unit and effective record before relying on it.
Plain-language statistics
Every summary measure has a defined job
The methodology favours transparent summaries that users can interpret. A simple average alone can be distorted by unusual values and should not stand in for the underlying evidence.
Sample or record count
The number of clean asking observations or verified official entries in the declared scope. It tells the reader how much evidence sits behind the result.
Median
The middle rate after sorting the observations. It is less affected by very high or low values than a simple arithmetic average.
First to third quartile
The band containing the middle half of a sufficiently sized asking-price set. It can describe a typical range without hiding the full observed span.
Observed minimum to maximum
The lowest and highest verified values in the declared set. For official guideline records, this complete endpoint range is the published summary.
Normalization examples
Price per cent = total asking price ÷ area in cents. Price per square foot = total asking price ÷ area in square feet. One cent equals 435.6 square feet. Original inputs remain attached to the observation so a conversion can be checked.
Freshness and quality control
A transparent result includes when and how it was checked
Market evidence changes. Official records can also change. Publication dates and review notes help a reader decide whether to recheck the source before using the information.
Observation window
Each price page should disclose the actual period used. Older, withdrawn or unavailable asking observations are not silently presented as current.
Show collection coverageSource recheck
Official references and retained public offers are checked against their traceable route before publication or material revision where access permits.
Record the checked dateVersioned correction
A material error is corrected with the affected page, source and reason in view. Uncertainty is not replaced with another unsupported claim.
Keep the change explainableWithholding decision
If scope, identity, unit, source quality or comparability cannot be resolved, publish the evidence limitation instead of an estimate.
No number is better than a false oneFound a source or correction?
Include the exact page URL, disputed statement, traceable public source and date observed. Do not email private title, identity or banking records.

Methodology questions
Property price evidence FAQs
Direct answers about asking prices, ranges, sample thresholds, duplicates, outliers, government records, withheld estimates and corrections.
Is an asking price the same as a completed sale price?
No. An asking price is the amount requested by a seller or advertiser. It can help compare current public offers, but it does not prove the price finally agreed, the amount registered or the market value of the property.
Why publish a price range instead of one number?
Properties differ by exact location, road access, size, frontage, shape, classification, approval status, utilities and condition. A range preserves those differences and avoids presenting one observation as the price of every property.
Why are at least five comparable asking observations required?
Five is the minimum publication threshold used by Kanyakumari Properties, not a guarantee of accuracy. Fewer observations make duplicate, unusual or mismatched records too influential, so no asking-price estimate is published.
How are duplicate property listings handled?
Listings that appear to describe the same property are grouped as one observation. Matching can use location, area, price, description, contact pattern, photographs and other public clues. The latest clear version is retained for review.
What happens to an unusually high or low price?
The source is checked for unit errors, missing context, bundled buildings, unusual access, size or condition. A defensible observation may remain and be labelled in the observed span. A suspicious or non-comparable record is excluded with a reason.
How is a government guideline-value range created?
Current official records are checked for a declared registration geography, guideline village, street or survey scope. The lowest and highest applicable entries in that verified set form the published range, with record count, check date, units and coverage stated.
Why might a page show no price estimate?
The available evidence may have fewer than five clean comparable asking observations, unclear units or location, excessive duplication, stale availability, mismatched property types or insufficient official record coverage. In that case the page should state the limitation.
How can I report a correction to the methodology or published evidence?
Use the contact or data-rights route and include the exact page URL, disputed statement, public source and observation date. A correction should be traceable, proportionate and recorded without replacing uncertain evidence with another unsupported claim.
