Blend and Extend: When to Renegotiate an Office Lease Early

Most companies don't think about renegotiating their office lease until the expiration date starts getting close. That's the default playbook, and for a lot of tenants it's the right one.

But under the right circumstances — a stable space need, a landlord that's motivated, a building going through some kind of change — waiting until renewal can mean missing an opportunity that's available right now. By the time your lease is actually up, the leverage that existed today may already be gone.

What Is a Blend and Extend?

A blend and extend is a lease restructuring strategy in which a tenant agrees to extend its lease beyond the current expiration date in exchange for the landlord revisiting the lease economics today. Depending on the circumstances, that may include lower rent, a reset of the operating expense or tax base year, rent abatement, tenant improvement dollars or other concessions.

In other words, a blend and extend allows tenants to potentially capture the value of their future office tenancy today.

It is not the right strategy for every company or every building. But for tenants with stable space requirements, approximately two to four years remaining on their lease and a landlord motivated to secure long-term occupancy, it is worth exploring before a traditional renewal process begins.

How Does a Blend and Extend Lease Work?

Say a company signed a 10-year office lease several years ago.

That lease set a rental schedule for the entire term, usually with annual rent escalations built in. The company knows what it's going to pay in years five, eight and 10 — and so does its landlord.

But the office market doesn't sit still for 10 years. Rental rates move, buildings trade hands, new owners put capital into properties, vacancy rises and falls, taxes and operating expenses change, and landlords roll out new concessions to win tenants.

So the economics a tenant locked in when the lease was signed can end up looking very different from what's actually available in the market a few years later. A Blend-and-Extend is one way to close that gap.

Rather than waiting for the existing lease to expire, the tenant offers the landlord something of value: a longer commitment to the building. In exchange for that additional term, the landlord may be willing to restructure some of the tenant's existing economics.

What Can Be Negotiated in a Blend and Extend?

Every building, lease and landlord is different. A blend and extend does not automatically produce a lower rental rate, so tenants should evaluate the total economic package rather than focus on a single number.

Depending on the circumstances, negotiations may include:

• A reset of the current rental rate
• Rent abatement
• A new tax and operating expense base year
• Tenant improvement dollars
• Funding for furniture or a refresh of the existing space
• Other economic or lease concessions

The timing of these benefits can vary. A landlord might provide some concessions immediately and hold others until the extended term begins. The benefits are rarely all front-loaded.

For tenants in modified gross leases, the expense base year can matter as much as the headline rent. A tenant that signed its lease years ago may now be paying several dollars per square foot above its original base year in tax and operating expense increases. Resetting that base year can meaningfully lower occupancy costs, even when the change to the face rental rate appears modest.

Tenants can also use a blend and extend as an opportunity to revisit other negotiable lease terms, including expansion rights, contraction rights, renewal options, signage, parking, operating expense exclusions and assignment or subletting provisions.

Why Would a Landlord Renegotiate a Lease Early?

A blend and extend has to work for the landlord, too. The primary thing landlords are buying is certainty.

A tenant with three years left on its lease represents three years of known income followed by a question mark. Locking that tenant in for additional years gives the landlord more visibility into future occupancy and cash flow, which can support the building’s long-term value.

Retaining an existing tenant also tends to cost the landlord less than replacing one. If a tenant likes its space and does not need a major buildout, the landlord’s cost to complete an extension may be relatively limited — mostly commissions, tenant improvements and some rent abatement.

Compare that with what happens if the tenant leaves at expiration: vacancy, construction costs, a new tenant improvement allowance, additional abatement and the expense of attracting a replacement tenant.

Given that math, giving up some economics today can be a good trade for a landlord looking to secure a tenant for longer.

Why Building Ownership Changes Can Create an Opportunity

One of the clearest signals that a blend and extend is worth investigating is a recent change in building ownership.

A new owner often comes in with a lower cost basis, a fresh capital plan and a need to generate leasing activity quickly. That combination can create real leverage for tenants.

New ownership may offer aggressive economics early while investing in amenities and common areas. It may also value early renewals because those transactions demonstrate momentum to prospective tenants and the brokerage community.

Those conditions may not last. As renovations wrap up, occupancy improves and leasing momentum builds, ownership typically begins pushing rental rates higher. For a tenant that already likes the building, there may be real value in exploring a lease restructuring before that transition is complete.

What Happens to Rents After a Building Changes Hands?

New ownership often moves through a familiar cycle: aggressive economics to build momentum, followed by rate increases once leasing activity and renovations gain traction. Chicago provides two examples.

At the Chicago Board of Trade, Cresa saw gross asking rates fall into the mid-$30s per square foot after Apollo took the property back in 2023, down from the low-to-mid $40s beforehand. As common-area improvements were completed and leasing activity increased, rates moved back above $40 per square foot in most cases—an increase of approximately 10% to 20% from their low point.

230 W. Monroe tells a similar story. After Menashe Properties acquired the building, ownership aggressively contested real estate taxes and gained greater control over operating expenses. As vacancy fell from approximately 40% to around 10%, quoted economics climbed into the high $30s and low $40s per square foot.

Every market has buildings moving through this cycle. The specific numbers will differ, but the pattern is consistent: the economics available while a building is being repositioned can look very different from those available once the repositioning gains traction.

Who Is a Good Candidate for a Blend and Extend?

A blend and extend makes the most sense for a tenant that can confidently trade additional term for economic value. In most cases, that means the tenant expects its current space to continue working well for the business.

Professional services firms tend to be good candidates because their headcount and space needs are often relatively steady. Law firms, accounting firms, financial services companies and similar office users may have a clearer view of their future requirements than businesses experiencing rapid staffing changes.

A tenant may be a good candidate if:

• Its office lease expires within approximately two to four years
• Its headcount and space requirements are expected to remain relatively stable
• It is satisfied with its existing space and building
• The building recently changed ownership
• Ownership is investing significant capital in the property
• Leasing activity at the building is increasing
• Its existing lease was signed in a stronger rental market and has continued escalating
• It is paying meaningful tax or operating expense pass-throughs above an older base year

On the other hand, a company expecting significant growth, contraction or another major change in its space needs may be better off preserving flexibility. The same is true for a tenant that already knows it wants to relocate.

How Early Can You Renegotiate a Commercial Lease?

There is no universal point at which a landlord will agree to renegotiate an existing commercial lease.

That said, a blend-and-extend conversation can become relevant several years before expiration. Cresa generally sees tenants within approximately two to four years of lease expiration as realistic candidates, although some landlords may reset economics earlier depending on the building and the circumstances.

What matters more than the number of years remaining is the value the landlord places on locking the tenant in for additional years. That depends on the tenant’s existing economics, current market rents, vacancy, the owner’s strategy, capital requirements and how important the tenancy is to the building.

Before entering a commercial lease negotiation, tenants should understand both their current lease position and the alternatives available in the competitive market.

Why It Can Be Worth Testing the Market Even If You Do Not Extend

Evaluating a blend and extend does not mean a tenant is committing to sign one.

A business that signed its lease five or six years ago may have limited visibility into today’s office market. Leadership knows what the existing lease requires, but may not know what its landlord would offer today — or what competing buildings would offer to win the company’s business.

Exploring the opportunity gives the tenant a current-market baseline. It can compare the existing lease against current building economics, evaluate competing properties and determine what its future commitment may actually be worth to the landlord.

If there is a compelling deal, the tenant can decide whether extending makes sense. If there is not, the tenant can remain under its existing agreement with a better understanding of its position when negotiating its commercial lease.

Do Not Assume Your Lease Has to Be Near Expiration to Create Leverage

Tenants often think of the time remaining on a lease as a disadvantage at the negotiating table. Under the right building conditions, it can be the opposite.

Those future years represent potential occupancy and cash flow for the landlord. For a tenant that wants to stay, offering more of that certainty can create leverage to revisit the lease economics sooner than expected.

How much opportunity exists will vary from building to building. Understanding the landlord, the property and the surrounding market is essential.
