Frequently Asked Questions
What is guideline value (vadikatti mathi) in Tamil Nadu?
Guideline value is the minimum per-unit price set by the Tamil Nadu Registration Department for every street and village. Stamp duty is paid on this value or the actual sale price — whichever is higher. You cannot register a property below its guideline value.
How is composite guideline value for an apartment calculated?
The composite value has two parts: (1) UDS area × land guideline value per sq ft, and (2) Flat built-up area × building construction rate per sq ft. Both rates are published by TNREGINET. The sum is the value on which stamp duty is calculated.
What is a "Ground" in Chennai — and does it vary?
A Ground is traditionally 2,400 sq ft in most Chennai localities. However it can vary in older parts of the city — some areas use 2,400 sq ft and others 2,200 sq ft. Always verify with the local SRO or existing sale deed for the exact definition applicable to a specific property.
How often is the guideline value revised in Tamil Nadu?
Guideline values are revised periodically — typically every 1 to 3 years. The last major revision was July 2024 with an average 10% increase in urban areas. Always check current rates on TNREGINET before calculating.
