Short answer: Diwali offers on flats in Bengaluru are worth what they cut from your total cost, in writing. A straight price cut is usually the cleanest, because it also lowers GST and stamp duty. "GST paid" and "stamp duty waived" can be real money if the base price wasn't raised. No-EMI schemes carry the most risk.
- Convert every offer into rupees against last month's price, not the brochure's "worth up to".
- A price cut works twice: on a ₹3.9 lakh cut, you also save about ₹49,000 in GST and charges.
- "GST paid" can shrink to little: in our example, a ₹300 per sq ft price rise turns a ₹4.9 lakh offer into a ₹68,000 saving.
- No-EMI schemes put the loan in your name. If the builder stops paying, the EMIs are yours. RBI warns about exactly this.
- The law caps your token: no more than 10% before a registered agreement for sale (RERA s.13).

From Navratri to Diwali, which falls on 8 November this year, most Bengaluru projects run some kind of scheme. Some save real money. Others repackage the usual price with a gift attached, and a deadline. This guide puts a rupee value on the common offers, shows where the catches sit, and lists what has to be in writing before you pay a token.
What kinds of festive offers will you see?
| Offer | What it means | How to value it | Main catch |
|---|---|---|---|
| Price cut per sq ft | Lower rate on the flat | Cut × area, plus GST and duty saved | Check it's on the final agreement value |
| "GST paid" or "GST absorbed" | Builder bears the 5% GST on an under-construction flat | 5% of the price (1% for affordable housing) | Base price may have been raised |
| "Stamp duty waived" | Builder pays duty and registration | About 7.6% of the higher of price and guidance value | Who pays if guidance value is higher? |
| Free car park, club or floor rise | A charge on the price sheet is dropped | The charge's value on last month's sheet | Was it ever charged to others? |
| Kitchen, appliances, gold coin | A gift or fit-out | Realistic resale value, not retail | Brand and spec vague; no cash option |
| No EMI till possession (subvention) | Builder pays interest on your loan for a period | Interest the builder covers | You owe the bank if it stops |
| Payment plan change (10:90, 20:80) | Less paid upfront | Interest saved on money you keep | Can be tied to subvention |
GST on an under-construction flat is 5%, or 1% if it qualifies as affordable housing (carpet area up to 60 sq m in a metro and value up to ₹45 lakh). There's no GST on a flat sold after the completion certificate. Stamp duty and registration in Bengaluru come to about 7.6% of the higher of the price and guidance value. See our full cost guide and stamp duty calculator.
Why is a straight price cut usually the cleanest?
Because GST and stamp duty are both charged on the price, a cut saves you money three times. Take a ₹300 per sq ft cut on a 1,300 sq ft under-construction flat (illustrative):
| Item | Amount |
|---|---|
| Price cut (300 × 1,300) | ₹3,90,000 |
| GST saved at 5% | ₹19,500 |
| Stamp duty and registration saved at 7.6% | ₹29,640 |
| Total saving | ₹4,39,140 |
This only holds while the price stays above the guidance value, because duty is charged on the higher of the two. Check the guidance value row on Kaveri; the 2023 rates are still in force.
Worked example 1: when "GST paid" isn't what it seems
Last month, the flat was ₹7,500 per sq ft plus GST. The festive offer is ₹7,800 per sq ft with "GST paid by the builder". All figures illustrative, for 1,300 sq ft.
| Step | Last month | Festive offer |
|---|---|---|
| Base price | ₹97,50,000 | ₹1,01,40,000 |
| GST at 5% | ₹4,87,500 | Paid by builder |
| You pay (price + GST) | ₹1,02,37,500 | ₹1,01,40,000 |
| Saving before duty | ₹97,500 | |
| Extra stamp duty and registration on the higher price (7.6% × ₹3.9 lakh) | ₹29,640 | |
| Net saving | ₹67,860 |
The brochure says "save ₹4.9 lakh". The real saving is under ₹68,000. That's why the first question is always: what was this exact unit's price last month? Ask for the earlier price sheet, or compare with the RERA-registered agreement values others have signed, if available. NDTV's festive report makes the same point: compare the final cost with what the same unit cost weeks earlier (NDTV, news).
Worked example 2: the no-EMI scheme that stops paying
You take an ₹80 lakh loan on an under-construction flat. The builder agrees to pay your pre-EMI interest for 24 months. By then, 60% of the loan, ₹48 lakh, has been released. Illustrative rate 8.5%.
| Step | Amount |
|---|---|
| Monthly interest on ₹48 lakh | ₹34,000 |
| Builder's promised cover over 24 months | ₹8,16,000 |
| If the builder stops after 12 months, your bill for the next 12 | ₹4,08,000 |
The loan is in your name, so missed payments hit your credit record, not the builder's. RBI's Master Circular says housing loans should be released by construction stage, upfront disbursal shouldn't be made for under-construction projects, and these schemes expose borrowers to the builder defaulting on the EMIs it promised (RBI Master Circular, para 4). If you take one, read the tripartite agreement, check that release is stage-linked, and keep enough cash to cover the interest yourself. Our bank-approved project guide covers the stage-linked rule in more detail.
What does the law say about offers and deadlines?
- Token cap. A promoter can't take more than 10% of the cost as an advance or application fee before a written, registered agreement for sale (RERA Act, s.13).
- Adverts must carry the RERA number and the authority's website address (s.11(2)). Check the project on the portal; our RERA check guide shows how.
- Ads are binding. If you pay based on an advertisement or model flat and lose out because it was false, the promoter must compensate you, or refund with interest if you withdraw (s.12).
- False urgency. The Central Consumer Protection Authority's 2023 guidelines list "false urgency" and "drip pricing" among 13 dark patterns treated as unfair trade practices (PIB, 8 Dec 2023). They're written mainly for online platforms, sellers and advertisers. Either way, a "today only" deadline is a reason to slow down, not speed up.
The LAMP check (our framework)
Run LAMP on every festive offer:
- L: Last month's price. What did this unit cost before the offer? Get it in writing.
- A: All-in cost. Price, GST, duty, parking, floor rise, club, maintenance deposit. Compare totals, not headlines.
- M: Money flow. Who pays what, when? Especially for GST, duty and subvention offers.
- P: Paper trail. Every promise in the allotment letter or agreement, with its rupee value.
How do the offers rank, in our view?
Ranked by how reliably they cut your total cost, assuming each is in writing:
| Rank | Offer | Why |
|---|---|---|
| 1 | Price cut on the agreement value | Cuts GST and duty too; easy to verify |
| 2 | Stamp duty and registration paid | Big amount; check the mechanics with your lawyer |
| 3 | GST paid, base price unchanged | Real if last month's price matches |
| 4 | Charges waived (parking, floor rise) | Real only if others paid them |
| 5 | Payment plan with less upfront | Helps cash flow; check the total |
| 6 | Freebies and gifts | Hard to value; no cash option |
| 7 | No EMI till possession | Most risk sits with you |
Checklist before paying a festive token
- [ ] Last month's price for this exact unit, in writing
- [ ] All-in cost sheet: price, GST, duty, parking, floor rise, club, deposits
- [ ] Offer and its rupee value written into the allotment letter
- [ ] RERA number on the ad matches the project on the portal
- [ ] Token within 10% until a registered agreement for sale
- [ ] Guidance value checked on Kaveri
- [ ] For "stamp duty paid": who pays, on what value, at which stage
- [ ] For subvention: tripartite agreement read; release stage-linked
- [ ] Refund terms if the loan isn't sanctioned
- [ ] No pressure to decide the same day
What mistakes do buyers make?
- Comparing headlines, not totals.
- Not asking for last month's price, so a "saving" can't be checked.
- Paying more than 10% before a registered agreement.
- Taking a no-EMI scheme without a cash buffer.
- Accepting verbal promises that aren't in the allotment letter.
- Valuing gifts at retail. A kitchen "worth ₹3 lakh" isn't ₹3 lakh off.
What should you do if...
...the offer ends "tonight"? Ask for it in writing with the expiry date. If it's real, a written offer can wait for your lawyer's look.
...the builder won't share last month's price? Compare with the RERA disclosures and similar units, and treat the offer as unproven.
...the offer is "stamp duty waived"? Ask whether the builder pays it at registration, on which value, and what happens if guidance value is higher. Get it into the agreement.
...you're offered a no-EMI scheme? Read the tripartite agreement and work out the interest you'd owe if the builder stopped paying.
...the booking form has clauses you don't like? See booking form red flags and our questions before accepting a builder offer.
...you're unsure about timing in general? See whether the data says it's a good time to buy in our 2026 market check.

Frequently asked questions
Some are. A cut in the agreement value is usually real and also lowers GST and duty. Offers bundled with price rises, or given as gifts, can be worth much less than advertised.
Only if the base price wasn't raised to cover it. Compare the total with last month's price for the same unit.
The builder agrees to bear stamp duty and registration, about 7.6% of the higher of price and guidance value. Get the mechanics written into the agreement.
They carry real risk. The loan is in your name; if the builder stops paying, you owe the EMIs. RBI warns about these schemes and says loans should be released by construction stage.
No more than 10% of the cost before a written agreement for sale is signed and registered, under RERA s.13.
A discount, in most cases. It's easy to verify and also cuts GST and duty. Gifts are hard to value and can't be swapped for cash.
If it's written into the allotment letter or agreement, it's part of the deal. Verbal offers are hard to enforce, so get everything in writing.
Not always. Developers often negotiate year-round. Compare the offer with recent prices for the same unit rather than the season.
