Everything on top of the price: the real cost of a Navi Mumbai flat
8 min read · Last verified
In short
The quoted price of a flat excludes stamp duty, registration, GST on under-construction purchases, and a list of developer charges covering parking, infrastructure, deposits and society formation. Together these add a material amount to the total, most of it payable in cash rather than through a home loan.
Key facts
- Largest addition
- Stamp duty and registration
- Applies only under construction
- GST
- Usually not loan-funded
- Duty, registration, and most developer charges
- Most negotiable
- Developer charges, more than statutory levies
- Most overlooked
- Society formation, deposits, and the first year of maintenance
Almost every buyer builds their budget around the price they were quoted, and almost every buyer is short. The additions are not hidden in any sinister sense — they are disclosed on the cost sheet — but they arrive as a list of unfamiliar line items at the point when the decision has already been made emotionally.
This sets out what those items are, roughly when each falls due, and which of them are actually negotiable.
The statutory levies
These are set by the state, not by the developer, and there is nothing to negotiate. They are also the largest single addition, and the one most often left out of a buyer's plan.
- Stamp duty — charged on the higher of agreement value and Ready Reckoner value, at registration.
- Registration fee — 1% of value subject to a statutory cap, at registration.
- GST — on under-construction purchases only, through the payment schedule.
Developer charges on the cost sheet
This is the list that varies most between developers and where the questions are worth asking. The naming is inconsistent across the industry, so compare the total of these lines rather than any individual one.
| Item | What it covers | Typically negotiable? |
|---|---|---|
| Parking | Allocation of a parking space | Sometimes, particularly on slower inventory |
| Infrastructure / development charges | Services and common infrastructure | Sometimes |
| Club or amenity charges | Access to shared facilities | Sometimes |
| Electricity and water connection | Utility connection and meters | Rarely — usually pass-through |
| Advance maintenance | A period of maintenance paid upfront | Occasionally on duration |
| Society formation | Cost of forming the co-operative society | Rarely |
| Corpus / sinking fund deposit | Reserve held for future major works | Rarely |
| Legal and documentation | Preparation of the agreement | Sometimes |
Ask for the complete cost sheet in writing, with every line item named, before you pay a booking amount. Compare totals between projects rather than base prices.
Costs on the finance side
If you are borrowing, the loan carries its own charges, and they are separate from anything the developer or the state levies.
- Processing fee on the loan.
- Legal and technical valuation charges levied by the lender.
- Insurance, where the lender requires or offers cover.
- For an under-construction purchase: pre-EMI interest during the construction period, which is a genuine and often underestimated cost.
The costs that arrive after possession
Budgets typically stop at possession. Real expenditure does not.
Interiors and fit-out are the obvious one, and the one most likely to be paid for on expensive credit because it was not planned. Beyond that, monthly maintenance begins, property tax begins, and in an under-construction purchase you may have been paying rent alongside your EMI for the whole construction period.
- Interiors, fittings, and anything the flat is not handed over with.
- Monthly society maintenance, which begins at possession.
- Property tax to the municipal corporation.
- Rent paid in parallel during an under-construction wait.
What to actually do about it
The defence is procedural rather than clever. Get the full cost sheet in writing before you commit, and build your budget from the all-in number rather than the headline.
- Ask for a written cost sheet with every line item named and totalled.
- Ask explicitly what is not on it — the question surfaces items the sheet omits.
- Compare projects on the all-in total, never on the base price.
- Confirm what your lender will and will not fund, in writing.
- Hold back a contingency. Something on this list will be larger than you expected.
