Buying Off-Plan Property in Israel: TAMA 38, Pinui-Binui, and Construction Index Risks

Off-plan purchases attract foreign buyers for an obvious reason: paying a 20% deposit now while keeping 80% of your capital invested abroad until the building is delivered three or four years later looks like a favorable cash management structure. Israeli developers market this aggressively, particularly in a high-interest-rate environment where deferred payment plans reduce the immediate cash burden.

What the marketing materials do not explain clearly is the Construction Input Index — a mechanism that caused hundreds of thousands of Israeli buyers to discover, at final handover, that the price of their apartment had inflated by hundreds of thousands of shekels beyond what they believed they had agreed to pay.

How Israeli off-plan purchases are structured

When you buy directly from a developer before construction is complete, the purchase agreement typically involves a staged payment structure. The standard "20/80" plan: 20% of the purchase price is paid upon contract signing, with the remaining 80% due at the time of possession — three to four years later.

For a foreign buyer, this appears to solve the liquidity problem created by the 50% LTV mortgage ceiling. You secure the property at today's prices with a manageable upfront payment, and you have years to arrange the balance.

But the balance is not fixed at the price written in the contract. It is linked to an index.

The Construction Input Index: the variable you must understand

Under Israeli real estate law, developers are permitted to link the unpaid balance of a new-build apartment to the Construction Input Index (Madad Tasumot Habniya — מדד תשומות הבנייה). Calculated monthly by Israel's Central Bureau of Statistics, this index tracks changes in construction expenses: concrete, steel, energy, transportation, and labor costs.

The practical consequence: if you sign a contract for a ₪3,000,000 apartment and pay ₪600,000 upfront, the remaining ₪2,400,000 balance is not locked. It floats against the construction index. If global supply chain pressures or local labor shortages drive the index up 5.3% annually — as occurred during the post-COVID inflation spike — your final balance at handover will be substantially higher than ₪2,400,000. You do not know the final price of your apartment when you sign the contract.

In the worst cases, buyers who committed at contract to a purchase they could afford discovered at handover that the inflated price exceeded their ability to fund the balance. They faced a binary choice: default on the contract and lose the deposit, or find emergency capital at short notice.

The August 2022 reform: what it changed and what it did not

In response to buyer losses from unconstrained indexation, the Knesset amended the Sales Law in August 2022. The reform imposed three specific constraints on developer indexation:

1. The first 20% of the total purchase price cannot be index-linked at all. Your initial deposit is locked in nominal terms.
2. No more than 40% of the total purchase price may be linked to the index. The remaining 40% (from the unlinked 20% deposit through to the statutory limit) is protected.
3. No indexation can be applied after the contractual delivery date. Delays in construction are the developer's problem, not the buyer's — the developer cannot continue indexing the balance after the date they promised to deliver keys.

The third point is particularly significant. It creates a direct financial incentive for developers to deliver on time, since delays impose fixed-price risk on them rather than passing inflation to buyers.

However, read this carefully: the reform protects 60% of the purchase price from indexation. The remaining 40% — the portion between your deposit and the 60% floor — can still be index-linked. On a ₪3,000,000 apartment, up to ₪1,200,000 of the purchase price can still float against the construction index over a multi-year build period. Audit every off-plan contract carefully against the statutory 40% maximum. Some developers still use contract language that attempts to push indexation beyond the legal limit.

TAMA 38: what it was and why it ended

TAMA 38 (National Outline Plan 38) was Israel's earthquake reinforcement program, active for 19 years. It permitted developers to add profitable penthouse floors to existing buildings in exchange for structurally reinforcing the building against seismic events and adding safe rooms (Mamad) to existing residents' apartments.

The TAMA 38 program was officially terminated nationally on August 29, 2024. The National Planning and Building Council ended the program after two decades of operation.

A small number of municipalities that submitted approved alternative plans received administrative extensions to process already-submitted TAMA 38 applications. The cities with confirmed extensions include Rishon LeTziyon and, on a temporary basis, Tel Aviv, Bat Yam, and Bnei Brak — with extended processing permitted until May 18, 2026.

The practical implication for buyers in 2026: if a property listing mentions "TAMA 38 potential" as a selling point, treat that claim skeptically. Unless the specific municipality has a confirmed, current extension explicitly in force, the TAMA 38 opportunity associated with that property is effectively obsolete. Real estate agents who continue marketing "TAMA 38 upside" in cities without active extensions are offering you a benefit that no longer exists under national law.

Pinui-Binui: Israel's active urban renewal framework

With TAMA 38 terminated, Israel's primary urban renewal mechanism is now Pinui-Binui (פינוי-בינוי — "Evacuation and Construction"). This is a macro-scale urban renewal framework operating on a completely different economic basis from TAMA 38.

Under Pinui-Binui, a developer acquires the consent of a majority (typically 66-80%) of apartment owners in an aging, low-density residential building. The entire structure is demolished. The developer then constructs a modern high-density tower on the same footprint. Existing apartment owners receive a brand-new apartment — typically larger than the original, with a reinforced safe room (Mamad), elevator access, and underground parking — at zero construction cost to them.

For existing apartment owners, participation is essentially free capital appreciation. For investors looking to speculate on Pinui-Binui projects, the strategy involves purchasing secondary apartments in aging buildings that are in the early stages of Pinui-Binui approval — securing those apartments at a discount and riding the value appreciation as the project advances toward regulatory approval and eventually demolition.

The catch: Pinui-Binui projects routinely take a decade or more to complete from initial consensus through municipal planning approval, tendering, demolition, and construction. The process involves complex negotiations with multiple municipal authorities and bureaucratic cycles that are genuinely unpredictable. For foreign investors pursuing a Pinui-Binui strategy, patience is not just advisable — it is a structural requirement of the investment thesis.

The safe room (Mamad) requirement

Any property built in Israel after 1992 is legally required to include a reinforced safe room (Mamad — ממ"ד), designed to provide occupants with protection during rocket or missile attacks. For new-build purchases, the Mamad is a standard feature and should be listed in the property specifications.

For secondary market purchases, the presence and condition of the Mamad is a specific inspection point for your attorney and surveyor. A Mamad is a dedicated, reinforced room with a steel door and sealed windows, distinct from simply having thick walls. Buildings constructed before the mandatory date may have had Mamadim added through TAMA 38 (while that program was active); older buildings that never underwent reinforcement may lack them entirely.

From both a practical and resale perspective, the absence of a Mamad is a significant issue for properties targeted at Israeli owner-occupiers. It affects the building's compliance status and the appeal to domestic buyers on resale. Verify the presence and condition of the Mamad during due diligence.

Due diligence checklist for new construction purchases

Before signing any off-plan purchase agreement in Israel:

1. Verify the developer is registered and licensed with the relevant regulatory authority
2. Confirm a bank guarantee covers your staged payments — under the Sales Law, developers must provide a bank guarantee or insurance policy for each payment tranche, protecting your capital if the developer fails
3. Audit the indexation clauses against the statutory 40% maximum
4. Confirm the contractual delivery date and the developer's liability for post-delivery indexation
5. Verify whether the building will be registered in the Tabu or Minhal upon completion, and that the lease will be capitalized (Mahuvan)
6. For projects marketed as TAMA 38: obtain written confirmation from municipal planning authorities that the specific project is under an active, approved extension
7. For Pinui-Binui buildings: obtain the current stage of municipal approval and a realistic project timeline
