    Commercial Property Due Diligence: The Checklist That Prevents a Costly Mistake

    Before signing a commercial property deal, there are seven layers of due diligence. Those who skip them pay the price for years.

    With commercial property, there is no second chance. Once you sign, you own the building, the lease, the rights and all the problems that were already there. Proper due diligence takes weeks, not days, and it is the least expensive tool in the transaction.

    First layer: rights and registration

    Check an up-to-date Land Registry extract, precise identification of the property, liens, cautionary notes, leasehold rights and their terms. For properties in condominiums and shopping centres, also check the bylaws and any areas appurtenant to the property, such as parking spaces and storage units.

    Second layer: planning and permits

    Request the building permit and the building file from the local authority. The key question is whether the actual use complies with the permitted use. A restaurant operating in premises approved as an office, or a warehouse converted for manufacturing without a permit, creates a risk of stop-work or closure orders, financing difficulties and problems when selling the property.

    Third layer: the lease and the tenant

    Read the lease in full, including options, indexation, adjustment dates, termination rights, repair clauses and securities. At the same time, examine the tenant: how long the business has been operating, its financial strength, and how dependent it is on this particular location.

    Fourth layer: actual expenses

    Request actual figures for at least two years: municipal property tax (arnona), management fees, insurance, electricity for common areas, maintenance and repairs. The gap between the expenses presented by the seller and the actual expenses is where returns disappear.

    Ready for the next step?

    Browse available commercial properties or get an offer for leasing out your own space.

    Fifth layer: physical condition

    Commission an engineering inspection. Check the roof, waterproofing, electrical systems, air conditioning, sewage, accessibility, fire safety and structural integrity. For industrial properties, also check floor load capacity, clear height and truck access.

    Sixth layer: taxation and VAT

    Review the transaction structure with a tax adviser: VAT, purchase tax, betterment tax and the impact of the ownership structure. In commercial property, VAT is part of the cash flow, not a footnote.

    Seventh layer: the vacancy scenario

    The question that concludes every due diligence process is simple. If the tenant leaves tomorrow, how long will it take to find another tenant, how much will the fit-out cost, and at what rent can the unit be leased? If the answer makes the transaction uneconomical, the price is too high.

    Questions and Answers

    What is the most critical check for a commercial property?

    Whether the actual use complies with the use permitted under the building permit. Non-compliance puts financing, leasing and the future sale at risk.

    How long does due diligence take?

    Usually several weeks, depending on the availability of the building file, tenant information and the engineering inspection.

    What expense data should be requested?

    Actual figures for at least two years: municipal property tax (arnona), management fees, insurance, electricity for common areas, maintenance and repairs.

    What should be checked in an industrial building?

    In addition to the standard checks: floor load capacity, clear height, truck access, three-phase electricity, waterproofing and fire safety.

    What should you do if the tenant's lease is about to expire?

    Price the transaction based on a vacancy scenario: the time needed to find a tenant, fit-out costs and a realistic rent for the next tenant.
