Every MMR buyer with a two-year horizon meets the same fork: the launch tower offering tomorrow at a discount, and the nearly-ready one selling certainty at full price. The general framework is the oldest in this blog's library; what MMR adds is scale, two codes, launch waves, and a register deep enough to price the fork properly. This is the regional edition, decided by filings.

Key takeaways

  • Launch stock typically opens 10 to 25 percent below nearly-ready equivalents in comparable MMR locations; the gap is the price of waiting time and completion risk.
  • Nearly-ready is scarce: 1,153 of MMR's 9,614 active registrations clear 80 percent built, one in eight, carrying about 30,000 unsold units against 288,048 in the under-30-percent band.
  • The register certifies the construction percentage, not the occupancy certificate: only 3.6 percent of active MMR registrations have an OC on file, because it arrives at the end and flips the status.
  • The discount is only cheap when the promoter's filed record, delivery history, QPR rhythm, certificate trail, earns the trust it asks for.
  • In the current market, record registrations and premium-heavy supply waves, crowded corridors widen launch discounts while clean nearly-ready stock commands its full premium.

What the gap is made of

The launch discount decomposes into three payments the developer makes to you: waiting cost (your rent and the EMI overlap through construction, computable from the money timeline); completion risk (the probability-weighted cost of delay, whose interest remedies compensate but never fully); and choice value surrendered (the nearly-ready buyer inspects a real flat; you buy a floor plan). GST does not separate them: 5 percent applies to both purchases until the completion certificate, so almost the whole sticker gap is risk being priced, which means almost the whole decision is risk being measured.

How much nearly-ready stock there actually is

The fork reads as a free choice between two options. On the register it is not, and the asymmetry is the first thing to know before negotiating either side.

Across MMR's five districts, 9,614 registrations currently read Active, and the construction percentages they file put them here.

Source: ReraGenie analysis of 55,913 published MahaRERA projects, as updated on 21 September 2026. Construction progress is the mean of the applicable RERA activity percentages filed per building, capped at 100. Unsold counts are summed from the building-level unit table, which about 40 percent of MMR projects file.

Nearly-ready is one active MMR registration in eight. 1,153 projects clear 80 percent, 12.0 percent of the active register, and between them they carry about 30,000 unsold units. The under-30 percent band alone carries 288,048. So a buyer willing to wait is choosing from roughly ten times the inventory, and one who is not is competing for a genuinely scarce thing. That is most of why the nearly-ready premium holds in a market where launch discounts widen: the premium is a scarcity price before it is a certainty price.

What "the OC path visible" can and cannot mean

The definition above asks for the occupancy certificate to be in sight, and it is worth being precise about that, because the register will almost never show you one on a project you can still buy into.

Of MMR's 9,614 active registrations, 348 (3.6 percent) have an occupancy certificate on file. Of its 8,688 Completed ones, 6,937 (79.8 percent) do. The certificate is the thing that ends the wait and flips the status, so a nearly-ready buyer is by definition buying before it exists. Even among active projects filing 90 percent or more construction, only 21 percent have one.

That is not a warning sign, it is the shape of the milestone, and reading it as a red flag would be the mistake. What it means practically is that the register can certify the construction percentage and the promised date, and cannot certify the OC. Ask the sales office for the OC application status in writing, and treat the answer as a claim rather than a filing, because that is exactly what it is.

An analogy: the forward contract

A launch booking is a forward purchase: today's price for delivery in 2028, counterparty risk included. Commodity traders price forwards off the counterparty's record and margin them accordingly; they do not sign forwards because the discount looked exciting at the launch event. The register is your counterparty file: delivery history, QPR rhythm, certificate trail, extensions. A 20 percent discount from a promoter whose last three towers landed on time is a priced forward; the same discount from a serial extender is a margin call waiting for your name.

The filings-based decision

Pricing the fork, project by project
  1. 1

    Compute the true gap

    Launch price plus waiting cost (rent-EMI overlap for the filed construction timeline, plus a slippage quarter or two) against the nearly-ready price. Sticker gaps of 20 percent routinely shrink to 8 to 12 after honest waiting math.

  2. 2

    Rate the forward's counterparty

    The promoter's filed record decides what discount is adequate: on-time deliverers can charge more for their forwards; wanderers must pay you more, and usually offer less.

  3. 3

    Verify the nearly-ready claim

    80 percent plus in the latest QPR and the promised date still ahead: nearly-ready is a filings status, not an adjective. The OC itself will not be on the file (3.6 percent of active MMR registrations have one), so ask for its application status in writing and treat that as a claim.

  4. 4

    Check the corridor's crowding

    Launch waves widen discounts where supply synchronized: a crowded catchment's launch discount is market pressure, not generosity, and its nearly-ready stock is the scarce asset.

  5. 5

    Match to your timeline, last

    A hard one-year deadline decides for nearly-ready regardless of arithmetic; flexibility is what launch discounts actually purchase.

Tip

The hybrid worth hunting in MMR right now: nearly-ready inventory inside launch-heavy corridors, where developers clearing older towers to fund new ones price certainty at a forward's discount. The filings find these: construction 85 percent plus, bookings suddenly accelerating, a new registration by the same entity nearby, the signature of a promoter recycling capital.

Meera prices both forks

Meera (illustrative, as ever) ran the arithmetic on her Thane shortlist's survivors: a launch at Rs 1.08 crore against a nearly-ready at Rs 1.26 crore, a 14 percent sticker gap. Her waiting math, 27 months of filed timeline plus one buffer quarter of rent-and-EMI overlap, consumed Rs 9 lakh of it; the launch promoter's record, one prior tower, delivered eight months late with a mid-scheme extension, repriced the remainder as inadequate. She paid for the certainty, moved in eleven weeks later, and watched the launch corridor add two more towers to its wave by year-end, a widening discount she felt no urge to re-price.

Both forks converge on the same requirement: the project's filed trajectory, read before money moves. The Rs 499 ReraGenie buyer report states the nearly-ready project's filed construction position, sets out the launch promoter's record across their other registrations and, where the filing is mapped, counts what else is registered within 2 km, for any covered MMR project, and the project watch that comes free with it follows the forward you eventually sign for 90 days.

The one-line summary

The launch discount is a forward contract's price for waiting and counterparty risk, and the nearly-ready premium is a scarcity price on one active MMR registration in eight: compute the true gap after waiting costs, rate the promoter from the register, verify the construction percentage in the filings rather than the OC that will not be there yet, and buy certainty when your calendar, or the counterparty's record, says the forward is mispriced.

Methodology and sources

  • Construction bands, project counts, unsold units and occupancy-certificate presence: ReraGenie analysis of 55,913 published MahaRERA projects, as updated on 21 September 2026, restricted to the 24,292 in Mumbai City, Mumbai Suburban, Thane, Raigad and Palghar. Progress is the mean of the applicable RERA activity percentages filed per building, capped at 100 before averaging.
  • An occupancy certificate counts as filed where a project's document list carries one under its own slot title; a promoter's declaration ABOUT a certificate is excluded, because it sits on half again as many projects and is a different document.
  • Unsold counts come from the building-level unit table, which about 40 percent of MMR projects file, so they describe filers rather than the region.
  • The MMR statutory boundary does not follow district lines in Raigad or Palghar; those are district totals that MMR dominates.
  • No price, discount or rate in this article comes from the register. MahaRERA files no per-flat price and no carpet area, so the 10 to 25 percent launch gap, the worked figures in the story and the GST treatment are market and tax facts from outside it, and the arithmetic in step one is a method rather than a measurement.
