Hidden Costs of Buying a Home

The sticker price is not the price. On top of it sit stamp duty, registration, GST if the flat is under construction, loan charges, brokerage, deposits collected by the builder or society, and the cost of moving in. We cannot honestly give you one national percentage, because stamp duty is set by each state and is usually the largest of these. What we can do is name every item and tell you which are fixed by law, which are negotiable, and which are pure padding.

Which of the extra costs are fixed by law?

Three are. The rest are commercial.

Rule or limit	Figure	Applies to	Statutory source
GST on affordable housing	1 per cent, effective rate	Under-construction residential, from 1 April 2019	CBIC, GST — An Update, 1 May 2019
GST outside the affordable segment	5 per cent, effective rate	Under-construction residential, from 1 April 2019	CBIC, GST — An Update, 1 May 2019
Input tax credit at these rates	Not available	The builder, and so ultimately the price	CBIC, GST — An Update, 1 May 2019
Affordable housing definition	Carpet area up to 60 sqm in metros, 90 sqm elsewhere, and value up to ₹45,00,000	Both metro and non-metro	CBIC, GST — An Update, 1 May 2019
TDS the buyer must deduct	1 per cent	Where consideration and stamp duty value are both ₹50,00,000 or more	Section 194-IA, per TRACES FAQs
Base for that TDS	Amount paid or stamp duty value, whichever is higher	Buyer of immovable property	TRACES FAQs on Form 26QB
Deposit of that TDS	Within 30 days from the end of the month of deduction	Form 26QB	TRACES FAQs on Form 26QB
Stamp duty and registration fee	Set by each state, not by the Centre	Every sale deed	State stamp acts

Two of those rows carry traps.

The affordable definition needs both tests met. Carpet area and value. A small flat above ₹45 lakh is not affordable housing, so 5 per cent applies. CBIC names the metros as Bengaluru, Chennai, Delhi NCR, Hyderabad, Kolkata and Mumbai. Delhi NCR here means Delhi, Noida, Greater Noida, Ghaziabad, Gurgaon and Faridabad. Mumbai means the whole MMR.

The TDS row is the buyer’s duty, not the seller’s. Miss it and the problem is yours. More on that at TDS on property sale.

What is the biggest hidden cost?

Stamp duty, in almost every case. It is charged on the higher of your price and the state’s circle rate. So a below-circle-rate bargain does not reduce it. Registration fee sits on top.

Because each state sets its own rate, we will not quote a single number. Look yours up on stamp duty by state and run it on the stamp duty calculator. Several states charge less when the buyer is a woman. That is worth checking before the deed is drafted, not after.

Circle rate matters twice over. It sets the stamp duty floor and it can create deemed income if your price is far below it. We cover the gap on circle rate versus market rate.

What does the builder charge that is not in the price?

This is where the padding lives. None of these are statutory. All are negotiable in principle, and most builders will not move on them.

Item	Details
Preferential location charges.	For a floor, a corner, a park view. Pure pricing.
Car parking.	Often billed separately, sometimes for a right rather than a title.
Club or amenity membership.	A one-time fee, then annual dues.
Interest-free maintenance deposit.	A lump sum held by the builder until the society takes over.
Advance maintenance.	Commonly one or two years, demanded at possession.
Electricity and water connection charges.	Meter, deposit and infrastructure.
Legal and documentation charges.	For the builder’s own paperwork.

Get every one of these in writing before you pay the booking amount. Once you have paid, your negotiating position is gone. If the project is under construction, read under construction versus ready first.

What does the loan cost beyond interest?

The advertised rate is a floor, offered to the strongest profiles. Around it sit charges that do not appear in the EMI.

Item	Details
Processing fee.	A percentage of the loan or a flat amount, plus 18 per cent GST on the fee.
Legal and technical valuation.	Charged whether or not the loan is sanctioned, at some lenders.
Documentation and franking or mortgage charges.	State-dependent.
Property insurance.	Often bundled at sanction. It is usually optional. Ask.

Compare on the total of rate plus fees, not the headline. Start at home loan interest rates and best home loans.

What else lands after possession?

Brokerage, where a broker is involved, plus 18 per cent GST on it. Municipal property tax from the date of possession. Monthly society maintenance. Interiors, which routinely cost more than the buyer planned. And moving.

One uncomfortable truth. Buyers budget for the down payment and stop. The costs above land in the same three months as the down payment, in cash, and they are not financed by the loan. That is what actually breaks home purchases, not the EMI.

Which of these can you actually negotiate?

Sort the list into three piles. It changes where you spend your effort.

Item	Details
Fixed by law.	Stamp duty, registration fee, GST and the 1 per cent TDS. No one can waive these. A seller who offers to is proposing something you should refuse.
Set by the lender.	Processing fee, valuation and documentation charges. These move. Lenders waive processing fees regularly, especially at quarter end. Ask, in writing, before you sign.
Set by the builder or seller.	Location charges, parking, club fees, deposits. These are price by another name. Argue on the total, not on each line.

Bundled insurance sits in a fourth category. It is sold as a condition and is usually not one. If a lender says the cover is compulsory, ask for that in writing too.

How should you budget for all this?

Get the state’s stamp duty and registration rate. That is your largest add-on.
Ask if the property attracts GST. Under construction usually does. Ready and registered resale is a different question. See GST on property.
Ask the builder or seller for a written, itemised demand sheet. Every line.
Add the lender’s fees, including 18 per cent GST on them.
Add brokerage, interiors and moving.
Keep the 1 per cent TDS aside if the deal is ₹50 lakh or more. You pay it, and you file Form 26QB.

Then check the paperwork before any of it is spent. The property legal checklist and home buying guide cover that.

Frequently asked questions

Is GST payable on buying a flat?

On under-construction residential property, yes. CBIC set the effective rates from 1 April 2019 at 1 per cent for affordable housing and 5 per cent otherwise, with no input tax credit.

What counts as affordable housing for GST?

Carpet area up to 60 sqm in metros or 90 sqm elsewhere, and value up to ₹45 lakh. Both tests must be met.

Do I have to deduct TDS when I buy a house?

Yes, at 1 per cent, where the consideration and the stamp duty value are both ₹50 lakh or more. It is deducted on the higher of the amount paid and the stamp duty value.

By when must the buyer deposit that TDS?

Within 30 days from the end of the month in which the deduction was made, using Form 26QB.

Why can’t you tell me the total percentage?

Because stamp duty is a state subject and the biggest single item. A national average would be a made-up number. Look up your state and add the rest.

Are builder charges like club membership negotiable?

In principle yes, in practice rarely. But you can insist on seeing every charge in writing before booking. That alone stops the worst surprises.
