Loan Against Unsold Flats After OC: Options and Holding Costs for Developers
A loan against unsold flats after OC is usually inventory funding: a lender takes a mortgage on a developer's completed, unsold flats and is repaid from sale proceeds in an escrow, with a fixed release price per flat. As of November 2026, the lender sizes the loan on valuation and sales pace and makes every credit decision.
The Diwali week is over, and many developers are now counting what did not sell. Some of that stock is finished: the occupancy certificate (OC) is in hand, the flats are ready, and every month they stay unsold costs interest, maintenance and property tax. Anarock's Q3 2026 report put available inventory in India's top 7 cities at about 6,30,600 units, 12% more than a year earlier, with an overhang of about 19 months at the current sales pace.
That count includes flats at every stage of construction, not only ready ones. But for a developer holding completed units, the question is the same: borrow against them, sell them faster, or both?
This guide explains the options for borrowing against completed, unsold flats as of 11 November 2026, and how lenders size and recover such loans. It also shows the real monthly cost of holding a ready flat, and two rules that change the maths once a project is complete: the GST treatment of ready flats and the two-year income tax window. It is general information, not financial, legal or tax advice. Every credit decision sits with the lender.
Loan against unsold flats: the short answer
A loan against unsold flats after OC is usually inventory funding. The lender takes a mortgage on the developer's completed, unsold units, sizes the loan as a share of their value, and is repaid from sale proceeds collected in an escrow account. Each flat sold must repay a fixed amount, called the release price, before the lender releases its charge on that flat for registration.
The other routes are narrower. Lease rental discounting works only if units are let to tenants with a steady rent. A loan against property needs other property as security. A top-up from the existing construction lender depends on how much of that loan is left and whether it can be extended. Our guide to inventory funding for unsold units explains the product from the ground up; this post covers what changes once the building is finished.
Why finished stock is a different problem
Three things change at completion.
First, the clock on cost starts running in full. During construction, interest is part of the project budget and sales come in as construction-linked payments. After OC, an unsold flat earns nothing while it keeps costing interest, maintenance charges to the society or association, and property tax.
Second, the GST position of the buyer changes. Under Schedule II, paragraph 5(b) and Schedule III, paragraph 5 of the CGST Act, 2017, sale of a flat is outside GST only when the entire consideration is received after the completion certificate or first occupation, whichever is earlier. A buyer of a ready flat in that position pays no GST on the price, which can help a slow project move.
Third, an income tax clock starts. Under section 21(5) of the Income-tax Act, 2025, an unlet flat held as stock-in-trade has nil annual value for two years from the end of the financial year in which the completion certificate is obtained. After that window, unsold and unlet flats can be taxed on the rent they could reasonably fetch, even if they earn none.
Your funding options for unsold flats after OC
| Option | Security | How it is repaid | When it fits | Watch out for |
|---|---|---|---|---|
| Inventory funding | Mortgage on the unsold units, plus escrow of their sale proceeds | Release price per flat from each sale | Project has OC, clean title and a believable sales pace | Release price can absorb most of each sale |
| Extension or top-up from the construction lender | Existing charge on the project | From sales, under the existing escrow | Construction loan still running and the lender is willing | Fresh appraisal and revised terms; the lender decides whether to extend at all |
| Lease rental discounting | Units let to tenants and the lease rentals | Rent paid straight into an escrow | Mainly commercial units with strong tenants | Rarely enough rent on residential flats; a let flat may sell more slowly |
| Loan against property | Another property the developer or promoter owns | EMIs from business cash flow | Inventory is already charged elsewhere | Puts other assets at risk; ties up promoter property |
| Bulk sale to an investor | Not a loan | One-time sale at a negotiated discount | Developer needs a quick exit on many units | Deep discounts and the section 53 stamp duty value test |
For commercial units with tenants, our guide to lease rental discounting covers sizing and tenor. For a loan backed by other property, see loan against property for business.
How inventory funding works for completed flats
- The developer lists the unsold flats with carpet area, floor, price list and any bookings in progress.
- The lender's valuer values the pool. Commercial banks follow RBI's Credit Risk Management Directions, 2025, updated as on 1 October 2026, which require at least two independent valuation reports for properties valued at ₹50 crore or above.
- The lender sanctions a loan as a share of that value, sets the tenor and fixes a release price per flat.
- The units are mortgaged and sale proceeds are routed to an escrow account the lender controls.
- As each flat sells, the escrow repays the release price first. The rest goes to the developer.
- Once the loan is repaid, the lender releases its charge on the remaining unsold flats.
Our guide to unsold inventory valuation explains how market value, stamp duty value and quick-sale value feed into step 2.
Worked example 1: sizing a loan on 40 finished flats
Illustrative example, assuming 40 unsold flats in a project with OC, a market value of ₹1.2 crore each, a loan of 50% of value, and a release price of 120% of the loan amount per flat:
| Item (illustrative) | Working | Amount |
|---|---|---|
| Value of the pool | 40 x ₹1.2 crore | ₹48 crore |
| Loan | 50% of ₹48 crore | ₹24 crore |
| Loan per flat | ₹24 crore ÷ 40 | ₹60 lakh |
| Release price per flat | 120% of ₹60 lakh | ₹72 lakh |
| Sale that clears the loan | ₹24 crore ÷ ₹72 lakh = 33.3 | 34th sale, leaving 6 flats unencumbered |
| Interest in the first month at an assumed 13% a year | ₹24 crore x 13% ÷ 12 | ₹26,00,000 |
At an assumed pace of 3 sales a month, the loan is cleared in about 11 to 12 months, ignoring interest paid along the way. A pool of 42 such flats would be worth ₹50.4 crore, past RBI's ₹50 crore mark, so ask your bank early whether it treats the pool as one property for the two-report rule. Actual loan shares, release prices and rates depend on the lender, the city, the project and the developer's track record.
What lenders check on finished stock
| Check | What the lender wants to see |
|---|---|
| Completion | OC or completion certificate, and RERA status of the project |
| Title and charges | Clear title, existing charges and a no-objection or release from the construction lender |
| Sales record | Bookings, cancellations and price trend for the last 6 to 12 months |
| Pricing | Price list against recent registered sales and the stamp duty value |
| Unsold mix | Which configurations, floors and towers are left, and why |
| Escrow | A sale proceeds account the lender can control |
| Developer | Track record, other projects, group debt and repayment history |
Completed projects usually look safer to a lender than projects under construction, because there is no construction risk left. The open question is sales pace. A lender will ask why the flats did not sell in the festive season and what will change.
The real monthly cost of holding an unsold flat
Interest is the largest cost, but not the only one. As the owner of unsold flats, a developer typically pays maintenance charges and property tax on them once a project is complete, and these add up across dozens of units.
The interest part is moving up, not down. RBI's Monetary Policy Committee raised the repo rate by 25 basis points to 5.50% on 7 October 2026 and changed its stance to calibrated tightening. Loans linked to an external benchmark such as the repo rate reset upward after such a hike, so check the rate in your own sanction letter. The next MPC meeting is scheduled for 2 to 4 December 2026.
Worked example 2: hold the flat or cut the price?
Illustrative example, assuming a flat priced at ₹1.2 crore carries ₹60 lakh of inventory loan at 13% a year, maintenance of ₹6,000 a month and property tax of ₹24,000 a year:
| Monthly cost (illustrative) | Working | Amount |
|---|---|---|
| Interest | ₹60 lakh x 13% ÷ 12 | ₹65,000 |
| Maintenance | Assumed | ₹6,000 |
| Property tax | ₹24,000 ÷ 12 | ₹2,000 |
| Total per month | ₹73,000 | |
| Total for 12 months | ₹73,000 x 12 | ₹8,76,000 |
On these assumptions, holding the flat for another year costs about 7.3% of its price. A price cut smaller than that, which sells the flat now instead of in a year, leaves the developer no worse off, before any change in market prices. The answer changes with the rate, the loan per flat and how fast the market is moving.
Mind the stamp duty value. Under section 53 of the Income-tax Act, 2025, if a developer sells stock below the stamp duty value and that value is more than 110% of the price, the stamp duty value is treated as the sale price for tax. With an assumed stamp duty value of ₹1.15 crore, any price below about ₹1.045 crore triggers that rule. The equal-cost price in this example, about ₹1.11 crore, stays clear of it.
The two-year tax clock on unsold flats
Section 21(5) of the Income-tax Act, 2025, in force from 1 April 2026, gives unsold flats a two-year shield. If a flat is held as stock-in-trade and is not let at any time in the tax year, its annual value is nil for two years from the end of the financial year in which the completion certificate was obtained.
That makes the completion date matter. Both tax laws refer to the completion certificate from the competent authority, so confirm which certificate your project holds and the date on it. A project that got its completion certificate in FY 2024-25 keeps the nil value only until 31 March 2027. A project completed in FY 2025-26 keeps it until 31 March 2028. After that, each unsold, unlet flat can be taxed on the rent it could reasonably fetch, less municipal taxes paid and a deduction of 30% of that value under section 22.
Worked example 3: what the end of the window can cost
Illustrative example, assuming 25 flats still unsold and unlet after the window ends, a reasonable expected rent of ₹30,000 a month each, municipal taxes of ₹24,000 a year each actually paid, and an assumed tax rate of 25%:
| Item (illustrative) | Working | Amount |
|---|---|---|
| Annual value | 25 x ₹30,000 x 12 | ₹90,00,000 |
| Less municipal taxes paid | 25 x ₹24,000 | ₹6,00,000 |
| Net annual value | ₹84,00,000 | |
| Less 30% deduction under section 22 | 30% of ₹84 lakh | ₹25,20,000 |
| Income from house property | ₹58,80,000 | |
| Tax at an assumed 25% | ₹14,70,000 |
That is about ₹4,900 a month for each unsold flat, on top of the costs in example 2. Interest deductions and the treatment of stock in your books depend on your facts, so check this with your tax adviser before you plan around it.
Ready flats and GST: why buyers notice
For buyers, a flat bought after the completion certificate, with the entire price paid after that date, carries no GST under the CGST Act, 2017. An under-construction flat does. If any part of the price was received before the completion certificate or first occupation, the sale counts as a construction service and GST applies.
Two practical points follow. A flat booked with money received before the certificate stays inside GST, so plan bookings in projects close to completion with that in mind. And when you compare a ready flat's price with an under-construction one nearby, include the GST the buyer would pay on the other. Your GST adviser should confirm how input tax credit rules apply to your project.
Common mistakes
- Waiting for the market to come back. Example 2 shows how quickly holding costs build. Run the numbers every quarter.
- Over-borrowing against slow stock. A high loan per flat pushes up the release price, so each sale leaves less cash for the developer.
- Ignoring the existing charge. The construction lender's charge must be released or shared before a new lender can take a mortgage.
- Discounting below the 110% band. A deep cut can create a tax bill on income the developer never received.
- Forgetting the tax clock. Projects completed in FY 2024-25 lose the nil annual value on 31 March 2027.
- Comparing headline rates only. Count processing charges, the release price and the escrow terms, not only the interest rate.
A checklist before you approach lenders
- Make a unit-wise list of unsold flats: carpet area, floor, price, stamp duty value and any active negotiations.
- Collect the OC or completion certificate, RERA registration and latest quarterly updates.
- Ask your construction lender for its outstanding balance and its terms for releasing or sharing the charge.
- Pull 12 months of bookings, cancellations and registered sale prices.
- Work out the monthly holding cost per flat and the date your two-year tax window ends.
- Decide the minimum price you would accept per flat, and check it against the 110% stamp duty value band.
