What Is an Expression of Interest (EOI) in Real Estate?
Learn what an Expression of Interest (EOI) means in real estate, its format, steps to submit one, refund rules and what Bengaluru buyers should check before paying.
Quick Summary (TL; DR)
An Expression of Interest (EOI) is a preliminary, non-binding document submitted to a builder or developer along with a small refundable amount. It formally indicates that you are seriously interested in buying a specific flat, plot, villa, or commercial space in an upcoming or ongoing project.
Unlike a full sale agreement, an EOI does not create any legal obligation to purchase the property, nor does it guarantee reservation of a particular unit. Builders mainly collect EOIs to:
Gauge real market demand for the project
Fine-tune their pricing and launch strategy
Offer early-bird discounts, better payment plans, or priority unit allocation to serious buyers before the official launch
It is a low-risk first step for buyers, but always verify the project’s RERA registration and carefully review the refund terms before submitting any money.
What Does Expression of Interest Mean in Real Estate?
An Expression of Interest is a written declaration that you want to buy a specific property. It is not a contract. It does not transfer any right in the property to you and it does not stop the builder from selling the same unit to someone else if you back out.
Builders use EOIs mostly in the pre-launch stage of a project. This is the period before the project is formally announced to the public, sometimes even before all approvals are in place. Collecting EOIs helps the builder understand how many buyers are interested in a location, unit size or price range before committing to a full marketing campaign.
Vault Expert Opinion
"An EOI signals intent, not commitment. The moment money changes hands, buyers assume they have a deal. That assumption is where most disputes start." - Property Law Consultant, Bengaluru
For the buyer, an EOI can mean early access to units, pre-launch pricing and a head start over the general public once bookings open. None of this is guaranteed in writing unless the builder puts it in the EOI form itself.
What Does an EOI Form Usually Include?
Element | What It Covers |
Buyer details | Full name, address, PAN, contact number, email |
Property preference | Project name, unit type, floor, facing, approximate size |
EOI amount | Usually between Rs 25,000 and Rs 2 lakh, though there is no fixed rule |
Payment mode | Cheque, UPI, NEFT or bank transfer |
Refund clause | Terms on when and how the amount is returned |
Validity | Time period the EOI stays active before it lapses |
Most builders keep the EOI form short. If a form asks for anything beyond basic identity, unit preference and payment details, read it twice before signing.
How to Submit an Expression of Interest? (Step-by-Step)
1. The builder announces a pre-launch or upcoming project through emails, ads or a sales office.
2. You collect the project brochure and check the builder's track record and the project's RERA status on the K-RERA website.
3. You fill in the EOI form with your details and preferred unit configuration.
4. You pay the EOI amount through the mode mentioned in the form.
5. You receive an acknowledgment receipt. Keep this safe.
6. Once the project is formally launched and registered, the EOI amount is usually adjusted against your booking amount or refunded if you choose not to proceed.

Is an EOI Legally Binding? What the Law Actually Says
An EOI itself is not legally binding. You can walk away from it without facing a breach of contract claim, as long as you have not signed any further agreement.
However, two parts of the Real Estate (Regulation and Development) Act, 2016 matter here.
Section 3 of RERA says a promoter cannot advertise, market, book, sell or invite people to purchase a plot, apartment or building unless the project is registered with the state RERA authority. Some legal experts point out that collecting EOIs before a project is registered can amount to inviting buyers to purchase, which sits close to what Section 3 restricts. This is a genuinely debated area and builders often argue an EOI is different from a booking. Treat an unregistered project's EOI as a higher-risk move, not a formality.
Section 13 caps how much a promoter can collect before a registered sale agreement is signed. A builder cannot take more than 10 percent of the total property cost as any kind of advance, including EOI and booking amounts combined, before the agreement is executed and registered.
Karnataka RERA has, in more than one case, ordered builders to refund the full booking amount when the buyer was not clearly told the terms before paying. Treat this as a sign that documentation and clarity matter more than assurances on a phone call.
What is the difference between Expression of Interest vs Booking Amount vs Sale Agreement
Factor | Expression of Interest | Booking Amount | Sale Agreement |
Purpose | Shows early interest | Reserves a specific unit | Creates a legal obligation to buy |
Binding | No | Usually no, until agreement is signed | Yes |
Amount | Nominal, Rs 25,000 to 2 lakh | Higher, often 5 to 10 percent of cost | Balance payment as per schedule |
Refundable | Yes, per the form's terms | Yes, minus admin charges in most cases | No, once registered |
Governing stage | Pre-launch | Launch | Post-launch, before registration |
Situation 1: Builder Asks for EOI Before RERA Registration
This happens more often than buyers expect, especially for large projects still waiting on plan sanction. Ask the builder directly for the RERA registration number or acknowledgment of application. If neither exists, treat your EOI amount as fully at risk and get every promise in writing.
Situation 2: You Want to Cancel and Get a Refund
Read the EOI form's refund clause before you sign anything. If the form does not mention a timeline, ask for one in writing over email. Most builders process EOI refunds within 15 to 30 days if you cancel before the formal booking stage.
Situation 3: NRI Buyers Submitting an EOI From Abroad
NRIs often submit an EOI remotely through a Power of Attorney holder in Bengaluru or by paying online through an NRE or NRO account. Make sure payments come from your own NRE or NRO account so the money trail is clean for any future loan or resale. Ask for the EOI receipt and refund terms over email so you have a record even if you are not in the country to follow up in person.

Common Mistakes People Make With an EOI
Mistake 1: Paying a Large Amount Upfront
An EOI is meant to be nominal. If a builder asks for a large sum before the project is even registered, that is a red flag, not a sign of a serious project.
Mistake 2: Not Checking the K-RERA Website
Before paying anything, search the project name on the Karnataka RERA website. If it does not show up, ask the builder why and get their answer in writing.
Mistake 3: Ignoring the Refund Clause
Buyers often skip reading the fine print because the amount feels small. A missing or vague refund clause is the single biggest cause of EOI disputes.
Mistake 4: Treating the EOI as a Confirmed Booking
An EOI reserves nothing by law. Builders can and do offer the same unit to multiple interested buyers until an actual booking is confirmed.
