Ready-to-Move vs Under-Construction Flats in Siruseri
Ready-to-move vs under-construction flats in Siruseri comes down to one trade. You choose between certainty today and a lower price over time. A ready-to-move flat lets you move in or rent it out at once. It carries no GST once the builder holds a completion certificate. An under-construction flat costs less at launch, lets you pay in stages and can gain value before handover. It also carries 5% GST, a wait of three to four years and some delivery risk. If you need a home now, choose ready. If you can wait and want growth, a RERA-registered under-construction project from a strong builder often works better.
What Each Option Means
A ready-to-move flat has finished construction and holds a completion or occupancy certificate. You can inspect the actual home, check water supply and move in soon after registration. In Siruseri, these flats come from resale stock, such as L&T Eden Park, or from unsold builder inventory.
An under-construction flat is still rising on site. You book from the floor plan, brochure and model flat, then pay as the tower rises. In Siruseri, Casagrand Jarvis targets possession in March 2028. Urbanrise The World of Joy targets December 2026.
Side-by-Side Comparison
| Factor | Ready-to-Move | Under-Construction |
|---|---|---|
| Possession | Immediate | Three to four years for new launches |
| GST | Nil, once the builder holds a completion certificate | 5% on the agreement value |
| Entry price | Higher, reflects current market | Lower at launch, rises with progress |
| Payment | Lump sum or quick loan disbursal | Staged, linked to construction |
| What you see | The actual flat | A model flat and plans |
| Rent saved | From day one | Only after handover |
| Delivery risk | None | Depends on builder and RERA timeline |
| Tax benefits on loan | Start immediately | Start after construction is complete |
The Cost Difference: GST and Stamp Duty
GST is the biggest cost gap between the two. Under-construction homes outside the affordable category attract 5% GST on the agreement value. On a ₹1 crore flat, that adds ₹5 lakh. A ready flat with a completion certificate attracts no GST at all.
Stamp duty depends on whether you buy from the builder or from a past owner. Since December 2023, Tamil Nadu registers first-sale flats through one sale deed on a composite value. Stamp duty and registration together come to 6% up to ₹50 lakh. The total is 7% up to ₹3 crore and 9% above that.
A resale flat follows the regular sale deed rate. That means 7% stamp duty plus a registration fee. Both apply to the guideline value or sale price, whichever is higher. So a resale flat can cost more in duty than a new flat of the same value.
The Case for a Ready-to-Move Flat
A ready flat removes most of the guesswork. You see the finished home, check the light, test the water pressure and meet neighbours before you pay.
It also saves you rent from the first month. If you pay ₹25,000 a month in rent today, a ready home saves you ₹3 lakh a year. Over a three-year wait, that adds up to ₹9 lakh that an under-construction buyer still pays.
Tax benefits on your home loan start at once too. You can claim interest and principal deductions from the first year, under the old tax regime.
The trade-off is price. Ready flats in good gated communities near SIPCOT trade at market rates, with little room for discounts. Older resale homes may also need upgrades to wiring, plumbing and interiors.
The Case for an Under-Construction Flat
An under-construction flat often costs less at launch than a similar ready home. Builders on OMR price early phases lower to fund construction, then raise prices as towers rise.
Siruseri shows how much this can matter. Average rates rose from about ₹3,750 per sq ft in 2022 to about ₹6,400 in 2026. Buyers who booked early in that window gained far more than those who bought ready homes later.
Staged payments also ease your cash flow. Under a construction-linked plan, you pay part of the price at booking and the rest in stages. Your home loan disburses in the same stages, so you pay interest only on the amount released.
RERA adds a layer of protection. The builder must register the project, follow the approved plan and deliver by the committed date. If the builder delays, the buyer can seek interest or a refund through TN RERA.
Risks You Should Check
Each option carries its own risks, and a careful check removes most of them.
For ready-to-move flats: Confirm the completion certificate, clear title and the encumbrance certificate. Check the age of the building, the state of the lifts and any pending dues to the association.
For under-construction flats: Confirm the TN RERA registration number before you pay any booking amount. Check the builder's delivery record, the RERA completion date and the payment plan in writing.
For both: Compare the carpet area, not just the built-up area. Ask for the full cost sheet, including parking, maintenance deposit and club charges.
