A Mortgage for a Contractor's Apartment: The Guide to Milestone Payments, Indexation, and Guarantees

A mortgage for a contractor's apartment is a home loan that accompanies the purchase of an apartment "on paper," where the funds are released in installments according to the actual construction progress rather than in a single lump sum at the handover of keys. This is the central feature that sets it apart from buying a second-hand apartment, and it affects the timing of the loan, the size of the early repayments, and the risks you should understand in advance. Buying from a contractor carries real advantages - a new apartment, spread-out payments, and sometimes a more comfortable price - but also layers of indexation, guarantees, and timelines that require precise financial planning. This guide explains how the mechanism works, what to watch for, and how to build the mortgage correctly from the very first step.

What Is a Mortgage for a Contractor's Apartment and How Is It Different

When you buy an apartment from a contractor in a project that is still under construction, you do not pay the full amount at the moment of signing. Instead, the purchase contract defines a payment schedule spread over the construction period, sometimes over two or three years. The bank financing the mortgage does not transfer the entire loan amount at once, but releases it in line with the payment schedule, stage after stage.

This difference is fundamental. With a second-hand apartment there is a one-time transaction: you sign, you pay, you receive keys within a few months. With a contractor's apartment the transaction stretches over time, and each payment installment requires a fresh release of funds from the bank. Therefore, contrary to a common perception, a mortgage for a contractor's apartment is not "just another mortgage" - it is an ongoing process that requires planning your cash flow throughout the entire construction period. This is one of the areas where professional mortgage consulting saves costly mistakes.

Payments by Construction Milestones (Installments)

The heart of the deal with the contractor is the payment schedule by construction stages, also known as "installments." The contract defines when each part of the consideration is paid, usually in line with physical progress on site: at signing of the contract, at completion of the frame, at completion of the plaster, at installation of the flooring, and up to handover of the apartment.

For the mortgage, this means the bank releases funds at each installment separately. In practice, this means that early on you use only part of the loan amount, and the monthly repayment is calculated only on the sum already drawn. As construction advances and further installments are released, the monthly repayment grows gradually until the loan is fully drawn.

The "Grace" Period During Construction

During the construction stages, many borrowers choose an arrangement of deferred principal payment, known as "grace." In this period you pay interest only on the drawn amount, or even defer the interest too, in order to ease cash flow at a time when you may also be paying rent on a current apartment. It is important to understand that deferral is not a "discount" - the deferred money accumulates and is repaid later, so the decision on grace should be planned rather than automatic.

Indexation of the Purchase Price to the Construction Inputs Index

One of the aspects that most surprises new buyers is the indexation. In most contractor purchase contracts, the unpaid balance of the consideration is linked to the construction inputs index - an index published by the Central Bureau of Statistics that reflects the cost of raw materials and labor in the construction sector.

The practical meaning: the price agreed in the contract is not necessarily the final price you will pay. If the construction inputs index rises during the construction period, every future payment installment becomes more expensive accordingly. In periods of inflation in the sector, the difference can accumulate to tens of thousands of shekels.

How to Guard Against the Indexation

There are several tools for coping with the indexation component. First, it is important to read the indexation clause in the contract carefully and verify which part of the consideration is linked and which is not. Second, you can consider bringing payments forward to "lock in" part of the price before index rises, but this requires available equity. Third, when building the mortgage mix you also take the contract's own indexation into account, so as not to be exposed twice to the same inflationary risk. This is where a planned mortgage mix that balances linked and unlinked tracks comes into play.

The Sale Law Guarantee - Your Security

When you pay a contractor money for an apartment that has not yet been built, the question arises: what happens if the contractor runs into trouble? Here the Sale Law (Apartments) (Assurance of Investments of Apartment Buyers) enters the picture, requiring the contractor to secure every payment you transfer.

The most common security is a bank guarantee under the Sale Law. For every installment you pay, the contractor issues you a bank guarantee in the amount of the sum. If the project fails or the contractor does not deliver the apartment, the project's financing bank returns the funds you paid. There are also additional security instruments such as an insurance policy or a caution note, but the bank guarantee is the most common and best known.

The iron rule: never transfer a payment to the contractor before you have received in hand the guarantee corresponding to that installment. A payment without a guarantee is a risk you must not take. Making sure every payment matches the guarantee that stands against it is one of the most important things in a deal with a contractor.

Timing the Mortgage Correctly

In a contractor deal, the question of timing is no less critical than the interest rate. The first payment to the contractor usually comes from your equity, and the bank enters the picture at more advanced stages. Correct planning of the order of funds prevents cash-flow pressure and unnecessary fees.

Equity at the First Stage

Usually, the first installment in the contract is paid from equity rather than from mortgage funds. Banks prefer that the borrower inject their own equity first, and only then begin releasing the loan funds. It is therefore important to plan in advance where the equity for the first payment will come from, whether from savings, from the sale of an existing property, or from other sources. The principles of equity are similar to those of a first-home mortgage, but the spread of payments adds an extra layer of planning.

When to Obtain Pre-Approval

Mortgage pre-approval is a step worth taking even before signing the purchase contract, or alongside it. The approval gives you certainty about the loan amount the bank is willing to provide, and lets you commit to the contractor with confidence. It is important to remember that pre-approval has a limited validity in time, and in a contractor deal that lasts years you may need to renew it. Proper coordination between the validity of the approval and the payment schedule is part of the planning.

Securities	Sale Law guarantee	Caution note and registration
Move-in date	Months to years away	Usually within a few months
Initial monthly repayment	Low and rising gradually	Nearly full almost immediately

The Main Risks and How to Cope With Them

Alongside the advantages, a contractor deal has unique risks that are important to know. Recognizing them early enables planning that reduces exposure.

• Handover delays - many projects are delivered late. A delay lengthens the period in which you pay both a mortgage and rent, so it is important to build a cash-flow safety cushion.
• Accumulated indexation - as noted, a rise in the construction inputs index makes future installments more expensive. You cannot predict the index, but you can plan scenarios and prepare for them.
• Validity of the pre-approval - an approval that expires mid-deal may leave you facing new and less favorable interest terms.
• Double exposure to inflation - combining an index-linked contract with linked mortgage tracks increases the risk. The design of the mix must take this into account.

Coping with all of these is not complicated, but it requires orderly planning and a forward-looking view. This is exactly the point where a personal mortgage consulting service makes the difference between a stressful deal and a calm, planned one.

Frequently Asked Questions About a Mortgage for a Contractor's Apartment

Does the monthly repayment start at its full amount from the first payment? No. Because the bank releases the mortgage funds in installments, the initial monthly repayment is calculated only on the sum actually drawn so far. As further installments are released, the repayment grows gradually up to the full repayment. Many also choose a grace period during construction to ease cash flow.

What is the Sale Law guarantee and why is it important? It is a bank guarantee that the contractor is obligated to issue for every payment you transfer, under the Sale Law (Apartments). It ensures that if the project fails you get your money back. The basic rule is never to transfer a payment before the corresponding guarantee is in your hands.

Is the price in the contract the final price I will pay? Not necessarily. In most contracts the balance of the consideration is linked to the construction inputs index, so if the index rises during construction, the future installments become more expensive. It is important to understand the indexation clause and plan the budget accordingly.

When should I obtain pre-approval in a contractor deal? It is recommended to obtain pre-approval even before signing the contract or alongside it, so you know with certainty the loan amount the bank will approve. In long deals you may need to renew the approval, so coordination between the approval's validity and the payment schedule is an important part of the planning.
