How to Sell an Under-Construction Flat Before Possession

Selling a flat before you receive possession from the builder — commonly called an under-construction resale or a pre-possession transfer — is legal in India and more common than many people realise. Whether you need to exit early due to financial reasons, a change in plans, or because property values in the project have appreciated and you want to book profits, this guide explains what you need to know as a seller.

Understanding What You Are Actually Selling

When you sell an under-construction flat before possession, you are not selling physical immovable property in the conventional sense. You are transferring your contractual rights in the property — specifically your rights under the allotment letter and the builder-buyer agreement (BBA) — to a new buyer. The new buyer steps into your shoes with the builder and will receive possession and the final sale deed in their name.

This distinction matters for several reasons:

• The transfer must be acknowledged by the builder. Most builders require you to inform them of the transfer and charge a nominal transfer fee (sometimes called a transfer of rights fee or NOC fee). The quantum varies by developer — read your BBA for the specific clause.
• The registration of the final sale deed will happen when the project is complete and the builder executes it with the new buyer. Until then, the transfer of your rights is typically documented through a tripartite agreement (between you, the new buyer, and the builder) or through a deed of assignment.
• Since the flat is not yet registered in your name, the chain of title is through your BBA and allotment letter, not through a registered sale deed. This is important for the buyer's due diligence.

Documents You Need to Arrange as the Seller

Before you invite any buyer to inspect the project or discuss pricing, collect the following:

• Original allotment letter from the builder in your name.
• Builder-buyer agreement (BBA), ideally registered. In states where RERA is active, the BBA must be registered.
• Payment receipts showing all instalments paid to date and the outstanding amount (if any) left to pay before possession.
• RERA registration certificate of the project. Any under-construction project with more than a specified number of units must be RERA registered. Share the RERA project ID with prospective buyers so they can verify the project status, approved plans, and completion timeline independently.
• Builder's NOC or transfer permission letter: Some builders require pre-approval before you can even market the flat. Check your BBA and contact the builder's resale desk early.
• Statement of dues: A statement from the builder showing what is outstanding, including any dues, charges, or penalties for delayed payments.

Buyers of under-construction resales tend to be particularly careful because they are paying for a property they cannot yet physically occupy. Presenting complete, authentic documentation builds trust and accelerates the process.

How the Transfer Actually Works

Once you have found a buyer and agreed on a price, the typical transfer process for an under-construction resale involves these steps:

• You submit a transfer request to the builder along with the buyer's KYC documents and the transfer fee.
• The builder issues a transfer letter acknowledging the change of allottee from your name to the buyer's name.
• A tripartite agreement or deed of assignment is executed between you, the buyer, and the builder (or between you and the buyer, with the builder as a consenting party). This is typically registered to give it legal standing.
• Future instalments to the builder are paid by the new buyer. The builder updates their records to reflect the new allottee.
• At project completion, the builder executes the final conveyance deed in the buyer's name.

The exact procedure varies by builder and state. Some large developers have a dedicated resale desk and a standardised process. Smaller developers may handle this less smoothly — budget extra time and keep a paper trail of every communication.

Tax Implications for Under-Construction Resale Sellers

The tax treatment of under-construction resale gains has specific nuances and has been subject to evolving judicial and departmental guidance. Here is the framework as it generally stands, but confirm with your CA before you file:

Holding period: For capital gains purposes, the holding period on an under-construction property is generally counted from the date of allotment (or the date of the BBA, in most interpretations) to the date of transfer. If this period exceeds 24 months, the gains are typically treated as long-term capital gains (LTCG). However, because you are transferring rights rather than a registered property, there have been differing views on this — your CA should confirm the current position.

TDS under Section 194-IA: If the sale consideration is ₹50 lakh or more, the buyer deducts 1% TDS. This applies to the total consideration you receive, not just the profit. The TDS is credited against your final income tax liability.

GST: For the buyer purchasing from you (as the original allottee in resale), GST treatment differs from a first-purchase. Typically, in a resale by an individual allottee who is not a developer, GST does not apply on the transfer fee you receive — but the buyer will still pay GST on the remaining instalments to the builder for an under-construction property. Confirm the GST position based on the specific structure of your transaction.

LTCG exemptions: Section 54 (reinvestment in residential property) and Section 54EC (capital gains bonds) may be available, depending on whether the transfer qualifies as LTCG. The ₹50 lakh ceiling on 54EC investment has remained unchanged for some time — check if it has been revised.

Pricing an Under-Construction Resale

Your pricing benchmark is the builder's current launch or available price for a similar configuration in the same project — if the builder is still selling unsold units. If the project is sold out, comparable RERA-registered resale transactions in the same building or adjoining projects set the market.

Your "floor price" is typically the total you have paid to the builder plus transfer charges and any other costs. Your ceiling is what a buyer would pay versus buying directly from the builder (or a newer, competing project nearby). In appreciated markets, resales can command a premium over the builder's original price — this is your profit. In slow markets, you may have to sell close to cost or negotiate on who bears the builder's transfer fee.

Be transparent about the outstanding instalments the buyer will need to service. Total cost of ownership for the buyer = what they pay you + remaining payments to the builder + registration costs at possession. Buyers who understand the full picture make faster decisions.

Finding a Buyer for Your Under-Construction Flat

Under-construction resales attract a specific type of buyer: those who either could not get an allotment in the original launch (if the project is popular) or those who want a unit in an ongoing, partially developed project at a price lower than a ready-to-move property nearby.

The best way to reach these buyers is to list early, price clearly, and present complete documentation. List your property for free on BookPropertyVisit to connect with verified buyers who are actively looking. The platform handles site visit coordination, so interested buyers can visit the actual project site in an organised manner. You pay nothing to list and nothing in commission unless the sale completes — see how selling works on BookPropertyVisit for details.

Frequently Asked Questions

Can I sell an under-construction flat if I still have EMIs or instalments to pay?

Yes, you can sell even if instalments are outstanding, but the structure needs to be handled carefully. Typically, the sale price covers both your profit and the outstanding dues. In the transfer process, the buyer either pays the builder directly for future instalments, or the transaction is structured so that the outstanding amount is deducted from what you receive and settled with the builder at or before the transfer is recorded. Ensure the buyer is clear about how much remains payable to the builder after they take over your rights — this is a key negotiating point and must be reflected in the tripartite agreement or assignment deed.

What happens if the builder refuses to permit the transfer?

Builders cannot arbitrarily block a transfer without reason — RERA provides buyers (and resellers) rights against unreasonable developer conduct. However, your BBA may contain specific conditions for transfer approval, such as all dues being cleared before transfer. If the builder is unresponsive or unreasonably withholding consent, a RERA complaint is a remedy available to you. Ensure your BBA is RERA-registered, and check the project's RERA registration status — projects under RERA are subject to the authority's oversight for such disputes. Document all correspondence with the builder in writing.

Is it safer to buy or sell an under-construction flat once the project is complete?

From a risk and documentation standpoint, yes — completed projects with an occupancy certificate offer a cleaner transaction because the title is fully formed and there is no construction risk. However, selling before possession allows you to exit at the peak of appreciation in some markets. If you are selling an under-construction flat, mitigating risk means choosing a buyer who understands the nature of the transaction, using a registered transfer document, and ensuring the builder acknowledges the transfer in writing before funds change hands.

Does the buyer pay stamp duty twice — once on the transfer and once at possession?

In most states, the buyer pays stamp duty at possession when the final conveyance deed is executed by the builder. The earlier tripartite agreement or assignment deed also attracts stamp duty (the rate varies by state — it is typically lower than the full conveyance deed rate). Whether the stamp duty paid on the assignment deed is adjusted against the possession deed stamp duty depends on the state's specific rules. Your property lawyer or the sub-registrar's office can confirm the applicable stamp duty at both stages.
