Thinking of buying an under-construction flat with a "Pay 10% now, rest on possession" scheme? Discover why the RBI cracked down on these 20:80 subvention schemes and how they destroy your CIBIL score.

Imagine this: You walk into a lavish real estate sales office. You want to buy your first home, but it's an under-construction property that will take 3 years to build. You are currently paying ₹40,000 in rent, and the thought of paying both rent and a Home Loan EMI sounds financially suicidal.
The smartly-dressed sales agent smiles and says: "Don't worry. We have a special 10:90 Subvention Scheme. You pay just 10% today. The bank funds the rest. And the best part? Our company will pay all the interest on your loan until we hand over the keys. You enjoy a 3-year EMI Holiday!"
It sounds like a once-in-a-lifetime deal.
It is actually a mathematical trap designed to transfer all the developer's financial risk directly onto your shoulders.
Here is the brutal truth behind real estate subvention schemes, why the RBI hates them, and why first-time homebuyers must avoid them at all costs.
A subvention scheme is a Tripartite Agreement between You, the Builder, and the Bank.
On paper, this sounds like a win-win-win. You get a house without paying heavy EMIs immediately. The bank gets a new loan customer. The builder gets the cash to build the tower.
But here is where the math—and the reality of Indian real estate—breaks down.
Why would a developer willingly pay the interest on your loan? Because they don't have money, and banks refuse to lend to them directly.
When a real estate developer goes to a bank for a corporate construction loan, the bank sees high risk and charges them an interest rate of 15% to 18%.
However, you are a salaried professional with a great CIBIL score. If you take a home loan, the bank charges you 8.5%.
By convincing you to sign a 10:90 scheme, the builder is legally using your good credit score to borrow millions of rupees at a cheap 8.5% rate. The builder gets the cash upfront, and you take 100% of the liability.
Here is the darkest secret of the subvention agreement: The loan is entirely in your name.
The builder signs a separate side-agreement promising to pay the Pre-EMIs to the bank on your behalf. But what happens if the builder runs out of money and stops making those monthly interest payments to the bank?
The bank does not care what the builder promised you.
Because the loan is tied to your PAN card, the bank immediately reports a default against your name to the credit bureaus. Your CIBIL score will drop by 100+ points overnight. If you don't step in and pay the builder's defaulted EMIs out of your own pocket, the bank will initiate legal recovery proceedings against you, not the builder.
Thousands of homebuyers in Noida and Gurugram faced this exact nightmare when their developers went bankrupt in 2018-2020. They were left with no house, a destroyed credit score, and banks harassing them for loan recovery.
Builders are businesses; they do not do charity. The 3 years of interest they promise to pay the bank isn't coming out of their profit margins. It is baked into the price of your flat.
If a flat under a normal Payment Plan costs ₹1 Crore, the exact same flat under a 10:90 Subvention Plan will be priced at ₹1.10 Crore to ₹1.15 Crore.
You are effectively paying a massive, hidden premium just for the illusion of an "EMI Holiday." When you calculate the math, you are paying the builder extra money now so the builder can pay your interest later. It is financially nonsensical.
Because developers were taking the upfront 90% bank disbursements and illegally diverting the funds to start other projects (instead of finishing the one they sold you), the Indian regulatory bodies intervened.
The Reserve Bank of India (RBI) and the National Housing Bank (NHB) cracked down heavily on these schemes. They instructed banks and Housing Finance Companies to stop aggressively funding models where developers pay the interest. They mandated that loan disbursements must strictly be linked to the actual physical completion of construction stages.
However, greedy developers still find loopholes, often partnering with smaller shadow banks (NBFCs) to offer slightly modified "15:85" or "No EMI till possession" deals.
If you are buying an under-construction property in 2026, the only safe method is a Construction-Linked Plan (CLP).
In a CLP, the bank only releases funds to the builder as physical milestones are achieved (e.g., 10% on casting the foundation, 10% on the 5th floor slab, etc.).
Yes, this means you will have to pay the Pre-EMI out of your own pocket while simultaneously paying rent. It is financially painful in the short term. But mathematically, it ensures that your loan liability is directly tied to the actual bricks and mortar standing on the ground, protecting you from builder fraud, project abandonment, and CIBIL bankruptcy.
