Commercial Leasing — Real Estate Market

Differences from Residential Leasing

Commercial leasing is regulated significantly less than residential leasing. The parties have greater contractual freedom. Terms are longer, conditions are more complex, and amounts are substantially higher.

Types of Commercial Leases

Full Repairing and Insuring Lease (FRI) — UK

The tenant bears all expenses for repairs and insurance
The landlord receives "net" rent
Standard for single properties (single-let)

Triple Net Lease (NNN)

The tenant pays: rent + taxes + insurance + maintenance
Popular in commercial real estate (especially in US-style, spreading in Europe)
The landlord receives predictable net income

Gross Lease

The landlord includes all expenses in the rental rate
The tenant pays only rent
Higher nominal rate

Turnover Rent

Base rent + a percentage of the tenant’s turnover
Typical for shopping centers
Example: base €50,000/year + 5% of turnover over €1,000,000

Key Terms of Commercial Leasing

Break Clause

The right to terminate the lease on a certain date
Example: 10-year lease with a break at year 5
Conditions precedent: no arrears, vacant premises

Rent Review

Rental rate review (usually every 5 years in the UK)
Types: upward only (UK standard), open market review, CPI-linked
In the UAE: annual review for commercial leases

Rent-Free Period

Period with no rent payments (usually for fit-out)
Standard: 3–12 months (depends on lease term and scope of fit-out)
Example: 10-year lease in the City of London, rent-free 18 months

Service Charge

Share in the building’s common expenses (security, cleaning, elevators, HVAC)
In class A offices: £10–25/sq. ft (London), AED 20–40/sq. ft (Dubai)

WAULT (Weighted Average Unexpired Lease Term)

A key metric for assessing revenue stability:

WAULT = Σ (Remaining lease term × Annual rent) / Σ Annual rent

Example: A building with 3 tenants:

Tenant A: 3 years, €200,000/year
Tenant B: 7 years, €150,000/year
Tenant C: 2 years, €100,000/year

WAULT = (3×200 + 7×150 + 2×100) / (200 + 150 + 100) = (600 + 1050 + 200) / 450 = 4.1 years

High WAULT (>5 years) → stable income → higher property value.

Jurisdictional Features

UK: Landlord and Tenant Act 1954

Part II: tenant’s right to extend a commercial lease (security of tenure)
Can be excluded by agreement between the parties (contracted out)

Germany

Gewerbemietvertrag — commercial lease agreement
Less regulation than residential leasing
Indexed rent (Indexmiete) — linked to CPI

UAE

Ejari registration is mandatory for commercial leases as well
RERA Rental Dispute Centre — dispute resolution
Trade License linked to premises (changing premises = new license)

Commercial Landlord Strategy

Unlike residential leasing, a commercial landlord manages a complex portfolio of contractual terms. The key task is to balance two opposing interests: maximize current NOI (shorter lease terms = ability to raise rent more often) vs. maximize property value (long WAULT = stable income = higher capitalization upon sale). Experienced management companies use a "lease expiry profile" — distributing tenant lease expiries over time to avoid the situation where several tenants leave at once, which can create a cash-flow crisis.

Trends in Commercial Leasing: Flexible Offices and New Formats

The commercial leasing market is experiencing a structural transformation, accelerated by the COVID-19 pandemic and the subsequent spread of hybrid work. The traditional model of long-term office leasing with fixed layouts is giving way to flexible formats. Coworking operators (WeWork, IWG, Regus, and in the UAE — A4 Space, Astrolabs) are taking an increasing share of the office market: according to JLL, the share of flexible office space in Dubai reached 8–10% of the total office market in 2024. For landlords, this means a dilemma: lease the building to a traditional corporate tenant for 10 years or to a flexible operator with potentially higher returns, but also higher risk. In retail real estate, the opposite trend is observed: "experiential retail" — cinemas, restaurants, fitness centers, children's entertainment — is becoming the basis for mall traffic, offsetting the outflow of customers to online shopping. Landlords who adapt tenant composition to this trend show more stable occupancy rates.

Practical Assignments

Assignment 1. The owner of an office building in London (5,000 sq. ft) offers a 10-year FRI lease with a break at year 5. Rental rate £55/sq. ft, rent review at year 5 (upward only), rent-free 12 months. Calculate the effective rental rate for 10 years.

<details> <summary>Solution</summary>

Nominal rent: £55 × 5,000 = £275,000/year. Over 10 years: £2,750,000 − rent-free 12 months (£275,000) = £2,475,000. Effective rent: £2,475,000 / 10 = £247,500/year. Effective rate: £247,500 / 5,000 = £49.50/sq. ft (10% discount to headline rent).

Assignment 2. Calculate the WAULT for a shopping center with 5 tenants:

Carrefour: 8 years, AED 2,000,000
H&M: 4 years, AED 800,000
Starbucks: 6 years, AED 300,000
Cinema: 12 years, AED 1,500,000
Small tenants: 2 years, AED 500,000

<details> <summary>Solution</summary>

WAULT = (8×2000 + 4×800 + 6×300 + 12×1500 + 2×500) / (2000 + 800 + 300 + 1500 + 500) = (16,000 + 3,200 + 1,800 + 18,000 + 1,000) / 5,100 = 40,000 / 5,100 = 7.8 years. A good indicator thanks to long-term anchor tenant contracts.
