Short answer: Treat online property reviews as leads to check, not proof. Look at when they were posted, who wrote them and how specific they are. A burst of five-star reviews around a launch can hide a lower rating underneath. Then confirm the claims on K-RERA, in court and consumer records and on a site visit.
- Timing tells you a lot. In our example, removing a launch-week burst drops a 4.6 rating to 4.0.
- Small samples swing. One bad review moves an 8-review rating by 0.42 stars, and a 300-review rating by 0.01.
- Specific beats emotional. "Tower B handed over 14 months late" is checkable. "Amazing builder!" isn't.
- India has rules here. Endorsers must disclose paid links under CCPA's 2022 advertising guidelines.

Online property reviews are often the first thing you read about a project in Bengaluru, on maps, portals, forums and video channels. Some are honest. Some are paid. Most are somewhere in between: a happy buyer in year one who hasn't seen the maintenance bills yet. These 20 questions help you sort them.
T: When were the reviews posted?
- Did many five-star reviews arrive in the same few weeks, often around launch or a sales event?
- Are the recent reviews different in tone from older ones?
- Was the review written before possession, or after living there for a year or more?
- Do the dates line up with what the reviewer claims, such as "moved in last year" for a project still under construction?
R: Who wrote it?
- Does the reviewer have a history of other reviews, or is this their only one?
- Have they reviewed several projects from the same builder, all with five stars?
- Do they say whether they bought, rented, visited or work in sales?
- If it's a video or social post, do they say whether they were paid or given anything? CCPA's 2022 guidelines on misleading advertisements and endorsements require endorsers to disclose such links.
A: How specific is the account?
- Does it name a tower, a phase, a handover month or a defect?
- Does it describe what the builder did after a complaint, not just the complaint?
- Is the language copied across several reviews, word for word or nearly so?
- Is it about the flat, or about the sales experience on one visit? If a review mentions a discount or freebie, test it with our questions before accepting a builder offer.
C: Can you cross-check it?
- Does the project's K-RERA page show the completion date the review implies? Search on K-RERA.
- Has the builder filed the quarterly updates that Section 11(1) of the RERA Act requires? Our RERA project review shows what to look for.
- Are there consumer cases against the builder? Complaints to consumer commissions are filed through e-Daakhil. For a proper search of past cases, ask a lawyer.
- Have earlier projects from the same builder delivered on time? Our study of whether east Bengaluru projects deliver on their RERA date shows how to test this.
E: Is there evidence?
- Are there photos of the actual building, with something that dates them?
- Will the reviewer talk to you directly, or answer a follow-up question?
- Can you meet two residents yourself on a site visit?
- Does what you see match the review: the lifts, the water, the common areas?
What does a review burst do to a rating?
Worked example 1: a launch burst. A project shows 120 reviews with an average of 4.6 stars. You scroll and notice that 70 of them were posted within three weeks of a launch event, all five stars.
- Total stars: 120 × 4.6 = 552
- Burst stars: 70 × 5 = 350
- Remaining stars: 552 − 350 = 202
- Average of the other 50 reviews: 202 ÷ 50 = 4.04
So the rating from reviews spread over time is about 4.0, not 4.6. That doesn't prove the burst is fake. It does tell you the headline number isn't the one to trust.
The figures are illustrative. Most platforms let you sort by date, so you can do this check on a real project in about ten minutes.
Why do small samples mislead?
Worked example 2: one bad review. Project P has 8 reviews averaging 4.8. Project Q has 300 reviews averaging 4.2. Each gets one new one-star review.
| Project P | Project Q | |
|---|---|---|
| Reviews before | 8 | 300 |
| Average before | 4.8 | 4.2 |
| Total stars before | 38.4 | 1,260 |
| After one 1-star review | 39.4 ÷ 9 = 4.38 | 1,261 ÷ 301 = 4.19 |
| Change | −0.42 | −0.01 |
P's 4.8 rests on eight people. It can swing a lot with one more opinion, in either direction. Don't compare a 4.8 from 8 reviews with a 4.2 from 300 as if they mean the same thing. When you weigh two projects, put ratings in their place alongside the facts, using our side-by-side comparison method.
Review red flags and what to check
| Signal | What it may mean | What to check instead |
|---|---|---|
| Many five-star reviews in a few weeks | A review drive around a launch | Rating with that period removed |
| Reviewer with one review only | New account, possibly paid | Whether they'll answer a question |
| Same phrases across reviews | Copied or templated reviews | Search a phrase in quotes |
| Only praise for the sales visit | Written before possession | Reviews from residents after handover |
| Delay complaints | Possible real delay | K-RERA dates and quarterly updates |
| No disclosure on a sponsored video | Possible paid endorsement | Whether the creator says so |
Are there rules against fake reviews in India?
Yes, though they don't cover every case. The Bureau of Indian Standards notified a standard for online consumer reviews (IS 19000:2022) on 23 November 2022. The government told the Rajya Sabha that it's voluntary and applies to platforms that publish consumer reviews, per PIB. CCPA's 2023 guidelines on dark patterns list disguised advertising among 13 specified practices. And the 2022 advertising guidelines cover endorsements.
None of this means a review you read has been checked. A standard is only as good as the platform that follows it, and we don't know which property platforms are certified.
The TRACE checklist
- [ ] Sorted reviews by date and checked for bursts
- [ ] Removed burst reviews and recalculated the average
- [ ] Checked reviewer histories for one-off accounts
- [ ] Noted which claims are specific and checkable
- [ ] Checked K-RERA dates and quarterly updates
- [ ] Asked a lawyer to search consumer commission and court records
- [ ] Spoken to two residents in person
Before you act on any review, also run the legal checks from title to OC and the 20 questions for an under-construction project. Reviews tell you what to ask. Documents tell you the answer.
What we don't know
We haven't measured how many reviews on property platforms are paid or fake, and we don't know of a reliable public figure for India. Platform rules on removing reviews also vary and change. Use the method on this page rather than any single rating.
This page is general information, not legal advice. For anything about consumer complaints or a builder's legal record, speak to a property lawyer.
Frequently asked questions
Use them as leads, not proof. Check when they were posted, who wrote them and whether the claims can be verified on K-RERA, in consumer case records or on a site visit.
Look for bursts of five-star reviews in a short period, one-off reviewer accounts, copied phrases and praise that's only about the sales visit. Then recalculate the rating without the burst.
Small samples swing. In our example, one bad review moved an 8-review rating by 0.42 stars but a 300-review rating by only 0.01.
CCPA's 2022 advertising guidelines require endorsers to disclose a material connection with the advertiser. A paid review that hides the payment may break those rules.
It's a Bureau of Indian Standards standard for collecting, moderating and publishing online consumer reviews, notified on 23 November 2022. It's voluntary for platforms.
Search the builder's earlier projects on K-RERA and compare the promised and actual completion dates. Our RERA delivery study shows the method.
Complaints to consumer commissions are filed through the e-Daakhil portal. To find past cases against a builder, ask a lawyer to search commission and court records for you.
It's our five-part check on a review: timing, reviewer, account details, cross-check and evidence. A review that passes all five is worth a follow-up question.
