The true cost of buying in Andheri West is reliably 12% or more above the base price you see advertised. At DLF The Westpark — DLF’s first residential project in Mumbai, on Oshiwara’s New Link Road — a 3 BHK listed at ₹5.75 Cr lands closer to ₹6.44 Cr once you fold in GST, stamp duty, registration, and the cluster of charges most buyers only discover at the agreement stage. This guide breaks every line item down so there are no surprises.

Quick answer: Budget roughly 12–13% over the base price for statutory and ancillary costs — 5% GST, ~6% stamp duty (including 1% metro cess), 1% registration, plus parking, club membership, advance maintenance, and legal fees. On a ₹5.75 Cr apartment the all-in cost comes to approximately ₹6.44 Cr before interior fit-out. Exact figures vary by floor, unit, and payment plan. Request the official cost sheet →

What you pay beyond the base price

When a developer quotes a base price, it covers the bare apartment and nothing else. Every buyer at DLF The Westpark — and across Mumbai’s under-construction residential market — must layer these additional costs on top:

Cost component Rate Basis
GST 5% On agreement value (under-construction)
Stamp duty ~5% base + 1% metro cess = ~6% On agreement value
Registration 1% On agreement value
Car parking (indicative) ₹10–20 L per slot Fixed charge per slot
Club membership (indicative) ₹2–5 L One-time
Advance maintenance deposit (indicative) ₹3–6 L Refundable / society corpus
Legal / documentation fees ₹30,000–75,000 Flat or % of value
Indicative total add-on ~12%+ Over base price

The statutory charges — GST, stamp duty, and registration — are non-negotiable and together account for roughly 12% of the agreement value. The remaining charges are project-specific; always request an itemised all-inclusive cost sheet before signing.

Illustrated cost build-up: a ₹5.75 Cr example

To make the numbers concrete, here is how the cost stacks up for a 3 BHK apartment at an indicative base price of ₹5.75 Cr. These are illustrative figures only — actual amounts will depend on the specific unit, floor, and payment plan agreed with the developer.

Line item Amount
Base price ₹5,75,00,000
GST @ 5% ₹28,75,000
Stamp duty @ 6% (incl. 1% metro cess) ₹34,50,000
Registration @ 1% ₹5,75,000
Statutory sub-total ₹6,43,00,000
Car parking (indicative) ₹12,00,000
Club membership (indicative) ₹3,00,000
Advance maintenance deposit (indicative) ₹4,00,000
Legal / documentation (indicative) ₹50,000
Indicative all-in cost ~₹6,62,50,000

The statutory costs alone push the outgo to approximately ₹6.44 Cr; once you add ancillary charges the total moves closer to ₹6.6–6.7 Cr. Interior fit-out and moving costs sit entirely on top of this figure.

Understanding stamp duty in Mumbai

Mumbai’s stamp duty structure is one of the more layered in India, which is why buyers are often caught off-guard. Here is how it works for residential purchases in 2026:

  • Base stamp duty: 5% of the agreement value, levied by the Maharashtra government.
  • Metro cess: An additional 1% levied to fund Mumbai’s metro rail expansion. This cess was introduced in 2019 and applies city-wide — it is not optional and is included in the effective 6% rate buyers in Andheri West (a metro-adjacent location) pay.
  • Calculation basis: Stamp duty is applied to the agreement value as registered with the sub-registrar — that is, the price you formally agree to pay the developer, inclusive of any premiums for floor-rise or preferred location.
  • Payment timing: Stamp duty must typically be paid at or before registration of the agreement for sale, which in under-construction projects like DLF The Westpark usually happens shortly after booking.

On a ₹5.75 Cr agreement value, the 6% effective stamp duty (5% base + 1% metro cess) works out to ₹34.5 L — the single largest add-on cost after the base price itself. Budgeting for this upfront is essential because stamp duty cannot be rolled into a home loan in most cases; it is an out-of-pocket payment due at the time of registration.

GST on under-construction property

GST is the second major statutory cost. The rate that applies depends on whether a project is under-construction or ready-to-occupy:

  • Under-construction projects (like DLF The Westpark, with possession targeted around 2029): GST is charged at 5% of the agreement value. No input tax credit (ITC) is passed on to the buyer.
  • Ready-to-move-in units with a completion certificate already issued: GST does not apply.

The 5% rate replaced the earlier 12% rate (with ITC) following a 2019 government revision intended to simplify the regime. While the headline rate dropped, the removal of ITC means the effective tax burden on the buyer is still material — ₹28.75 L on a ₹5.75 Cr apartment in our example. GST is payable to the developer as part of each demand milestone and is reflected in every payment demand letter you receive.

Important: GST is calculated on the agreement value, not the carpet-area rate alone. If the agreement captures parking, club membership, and other charges as part of a single consideration, GST may be levied on the blended amount. Confirm the breakdown in your agreement before signing.

Other charges buyers often overlook

Beyond the headline statutory costs, several project-specific charges catch first-time buyers by surprise. At a project of DLF The Westpark’s scale and positioning, expect to encounter some or all of the following:

Floor-rise premium

Developers typically add a per-square-foot or flat-rupee premium for higher floors. At a G+39 tower like those in Phase 1, the difference between a mid-floor and a top-floor apartment can be meaningful — sometimes ₹5–15 L or more. Always ask for the floor-wise pricing grid.

Preferred location charge (PLC)

A unit facing a garden, the amenity deck, or with an unobstructed city view may carry a PLC. This is over and above the base rate and the floor-rise premium, and it compounds the agreement value on which GST and stamp duty are calculated.

Car parking

Parking is rarely included in the base price at premium Mumbai projects. Budget for at least one slot (indicatively ₹10–20 L); a second slot, if available, costs additionally. The MahaRERA number for DLF The Westpark is PR1181012500079 — review the registered documents to confirm parking entitlements and charges.

Club membership and amenity corpus

A one-time club or amenity membership fee is standard at integrated township projects. This covers access to the clubhouse, pool, gym, and other shared facilities for the life of ownership.

Advance maintenance deposit

Developers collect between 12 and 24 months of anticipated maintenance charges upfront to fund operations before the residents’ association is formed. This amount is sometimes refundable, sometimes credited against future dues — confirm the treatment in your agreement.

Society formation / legal charges

Documentation, agreement drafting, and society formation charges are typically passed on to buyers. These are usually in the range of ₹30,000–75,000 and are one-time.

Budgeting checklist for DLF The Westpark buyers

  1. Get the all-inclusive cost sheet in writing before paying the booking amount. This should itemise every charge beyond the base price — PLC, parking, club, maintenance, and all statutory costs.
  2. Check the floor-rise and PLC grid for your shortlisted unit. Two apartments at the same base rate on different floors can differ by ₹15–20 L all-in.
  3. Set aside 12–15% over the base price as your total statutory and ancillary reserve. If you come in under-budget, the surplus covers interior fit-out or an upgraded parking slot.
  4. Align your home loan sanction with the payment plan. DLF The Westpark is a construction-linked project; draw-downs are tied to construction milestones, so your EMI outflow and loan interest are staggered. Pre-arrange a flexi or tranche-disbursement loan to avoid carrying full interest from day one.
  5. Confirm GST treatment of extras. Ask whether parking and club fees are bundled into the agreement value (making them subject to GST) or billed separately at a different rate.
  6. Budget for stamp duty as an out-of-pocket cost at registration, typically within 60 days of the agreement for sale. At 6% on ₹5.75 Cr that is ₹34.5 L in a single outflow — plan your liquidity accordingly.
  7. Factor in possession-stage costs. Interior fit-out for a 1,125–2,239 sq ft premium apartment in Mumbai typically runs ₹50–150 L depending on specification. This comes after possession (~2029) and is entirely separate from acquisition cost.

Frequently asked questions

What is the stamp duty rate in Mumbai for residential property in 2026?

The effective stamp duty rate for residential property purchases in Mumbai is approximately 6% — comprising a 5% base rate levied by the Maharashtra government plus a 1% metro cess introduced to fund the Mumbai Metro network. Both components are applied on the registered agreement value.

How much does the true cost exceed the advertised base price at DLF The Westpark?

Indicatively, buyers should budget 12% or more over the base price. Statutory costs alone (GST 5% + stamp duty ~6% + registration 1%) add up to 12% of the agreement value. Project-specific charges such as parking, club membership, and advance maintenance add further to the outgo. On a ₹5.75 Cr base price, the all-in cost comes to approximately ₹6.44 Cr in statutory costs and closer to ₹6.6–6.7 Cr including ancillary charges.

Is GST applicable on DLF The Westpark apartments?

Yes. DLF The Westpark is an under-construction project (MahaRERA: PR1181012500079) with possession targeted around 2029. GST at 5% of the agreement value applies to all under-construction residential units. No input tax credit is passed to the buyer under the current regime. GST becomes payable at each construction milestone as part of payment demand letters.

Can I include stamp duty and GST in my home loan?

Home loan lenders in India typically finance the base price and may include GST, but stamp duty and registration are generally treated as out-of-pocket costs to be paid directly to the government at the time of registration. Some banks allow a small component of these charges in the overall loan, but you should confirm with your lender. Plan for stamp duty (₹34.5 L on ₹5.75 Cr) as a lump-sum liquidity requirement around the time of agreement registration.

What is the booking amount for DLF The Westpark?

The booking amount is indicatively around 10% of the base price. This secures your unit and is adjusted against the total sale price. The balance is structured as a construction-linked payment plan tied to project milestones. Request the current payment plan schedule from the sales team as specific percentages and timelines are subject to the developer’s terms at the time of booking.

Where can I verify the project details officially?

DLF The Westpark is registered under MahaRERA with number PR1181012500079.
