When you compare flats in Kolkata, the advertised price is only the beginning of the budget. After registration, you may pay monthly common-area maintenance, a one-time corpus contribution, a sinking-fund contribution, utility bills, property tax and periodic repair assessments. A smaller apartment with inefficient common facilities can cost more to operate than a slightly larger flat in a well-managed building. The useful comparison is **total cost of ownership**, not just price per square foot.
What monthly maintenance actually pays for
The association or management company generally collects money to operate lifts, water pumps, security, corridors, common-area electricity, housekeeping, gardening, waste handling and fire-safety systems. In developments with pools, gyms or landscaped podiums, electricity, staff and servicing for those facilities may be substantial. Ask whether the quotation is based on carpet area, saleable area, apartment size, flat count or another allocation formula. Request the rule in writing, along with the current rate and last two years of changes for an occupied project.
Maintenance deposit versus sinking fund
A **maintenance advance or deposit** may cover early operating expenses or a defined service period. A **sinking fund** is intended for long-life assets such as lift replacement, waterproofing, facade repairs, pump replacement and major electrical equipment. Some associations also hold a separate corpus or reserve fund. These terms are not interchangeable. Ask who controls the money, whether it is refundable, how it is invested, who authorises spending and whether audited accounts are available. The building's ownership structure and applicable governing documents matter; the West Bengal Apartment Ownership Act recognises common areas and shared expenses in properties governed by that Act.
Example of a realistic annual budget
Consider an **illustrative** family budget, not a Kolkata market quotation: ₹4,000 per month in society maintenance equals ₹48,000 yearly. Add an illustrative ₹12,000 annual reserve contribution, ₹9,000 property tax and ₹6,000 average non-monthly repairs; the combined amount is ₹75,000 a year before electricity, internet or home-loan payments. Your building may be materially different. A buyer should ask for actual demand notices, utility submeter rules and the latest approved annual budget rather than adopting a generic figure.
Questions to ask before booking
- Is parking maintenance billed separately, and are commercial shops assessed differently?
- Does the quoted charge include water, power backup and clubhouse membership?
