The Entire Commercial Leasing Process, Start to Finish
DIY, traditional brokerage, or TenantBase — the full leasing process from search through move-in, what representation is actually worth in real dollars, and what tenants routinely miss before signing.
Renting commercial real estate isn't just about finding a place to run your business — it's a strategic investment in your future. The right location, at the right price, with the right terms, can make your office more productive, improve recruiting and retention, and help your bottom line all at once. This guide walks through the entire process, from deciding how you'll handle representation to signing the final lease — including what representation is actually worth, and what tenants routinely miss without it.
Commercial leasing has three real paths: DIY, traditional brokerage, or a tenant-first platform. Whichever path you take, the process runs through the same core stages — defining your needs, searching and touring, proposing and negotiating, signing, and moving in. A good advisor relationship doesn't stop at signing either; it continues through move-in and future space planning. Real tenant-rep firms report client savings in the tens of thousands of dollars on individual negotiations, and the two provisions tenants miss most often — holdover rate and operating expense allocation — can each carry real financial consequences if they're not caught before signing.
Part One: Choosing How You'll Handle Representation
Before any of the actual steps below, there's a more basic decision every tenant has to make: how are you going to find and negotiate this space in the first place?
The DIY Approach
Many businesses start their commercial real estate search working on their own, often because a senior team member — a VP of operations, say — has negotiated a lease before and believes the company can handle it internally. In practice, this runs into two consistent problems.
Traditional Brokerage
A good broker can make the process faster, ensure the space is a real fit, and negotiate everything from rent to parking. An existing relationship also pays off later, for renewals or future expansions. But the traditional brokerage model has real downsides too.
- The model is often built around large deals with bigger commissions, which can leave growing companies and smaller businesses with less attention.
- Brokers are sometimes financially incentivized to maintain exclusive relationships with certain property owners — a real conflict of interest when their job is supposed to be representing you.
The TenantBase Method
TenantBase takes a different approach: transparent, data-driven, tenant-focused, and free for renters. Every tenant is matched with a broker who works within a collaborative team focused entirely on getting the tenant the best deal.
"Most tenant rep brokers focus on landing big clients and don't really spend much time helping the home-grown businesses that make up the fabric of our city. Those businesses are left to work with brokers who have a responsibility to negotiate in favor of the landlords, without anyone looking out for their best interest."
— Andrew Nguyen, TenantBase Advisor
"I pride myself on being able to help someone who has struggled with finding the right space through other means — either because they weren't taken seriously, didn't know how to find it, or had bad representation."
— Ahi Naraghi, Senior Advisor at TenantBase
What Representation Is Actually Worth
Savings vary significantly by deal, market, and building — there's no universal number. But real examples give a sense of what's genuinely at stake in a negotiation. One tenant representation firm's published case studies report saving a client $75,000 over a five-year lease term through a $0.25 per square foot reduction in base rent, and separately negotiating $50,000 per year in after-hours HVAC cost savings for another client.1
These are illustrative examples from one firm's reported client work, not a guarantee of what any specific negotiation will produce. But they're a useful reminder that the difference between representation and no representation isn't abstract — it shows up in real, specific dollar figures on individual line items most tenants wouldn't think to negotiate at all.
Part Two: The Process, Start to Finish
Once you've settled on how you'll handle representation, the actual process runs through four consistent stages.
Settling on a Plan
By the time most tenants reach out to an advisor, they've already thought through budget, space requirements, possible locations, and the amenities or layout their organization needs. The first thing a leasing partner like TenantBase does is assign a dedicated representative to meet one-on-one and learn your specific needs and priorities.
The role of a good leasing partner isn't just to represent — it's to educate. Tenants often face complex needs that require some compromise, particularly smaller and mid-sized businesses. The goal is a strategy that gets you the best space possible for your needs, even when that means adjusting your initial approach.
Search and Tour
Once your needs are clear, your advisor provides a curated list of properties that match your requirements, then handles setting up tours. There are several types of commercial space worth considering — traditional and creative office, industrial warehouses, and a growing range of coworking options. In some cases, what a space could become matters more than what it is today: a landlord willing to offer good build-out terms can turn an industrial warehouse into a solid, often competitively priced traditional office.
The tour itself is your chance to evaluate more than the space — it's also your chance to evaluate the landlord. Ben Mizes, President of Clever Real Estate, learned this directly while searching for his own company's office:
"We found a great landlord willing to offer a flexible lease: we'd pay a discounted rate the first year, and closer to market rate as we grew into the space. We moved in with 12 employees to a 10,000 sq. ft. office, and even at 30 employees we still had plenty of room — I'm anticipating we can grow to 100 or so before needing a new space."
If your requirements are unusual — pay-as-you-go scalability, for example — the tour is exactly where you separate landlords who can meet those needs from ones who can't. After the first round of tours, most searches narrow to the top two or three properties. Highly specialized spaces can take up to six months to find; most searches move faster.

Presenting a Proposal
A commercial lease proposal isn't like a residential rental agreement — this is where a qualified advocate becomes genuinely valuable. The process starts with using real market data to request a price and terms; the landlord counters, and negotiation continues until both sides land on terms that work.
If build-out or construction is involved, this is also the point to walk the space with an architect or contractor. Tim Spiegelglass, President of Spiegelglass Construction Company — which focuses on small commercial retail and restaurant builds — puts the case directly:
"Our #1 tip for an entrepreneur looking to lease property is to have a general contractor who specializes in your industry look at the space before you sign a lease. Knowing that information upfront can save a lot of time and money, and can guide negotiations with your landlord."
Signing the Lease
Once both sides are happy with the terms, it's time for a lawyer to review the document and sign. But even lawyers without real estate-specific expertise can miss provisions that carry real financial weight. Two of the most commonly overlooked:
Unlike a residential lease, overstaying a commercial lease term doesn't quietly convert to month-to-month. Most leases default to 125% to 150% of base rent — sometimes doubling it — for holding over without consent. If there's any chance you'll need extra time, negotiate this rate down before you sign, not after.
Maintenance, taxes, and improvements are sometimes covered by the landlord in year one, then passed to the tenant. How the lease is worded determines your exposure — if you occupy 10% of a partially vacant building and the HVAC needs replacing, you could be on the hook for the full cost or just your 10% share, depending entirely on the language.
These are two of the most consequential provisions tenants miss — see Lease Negotiation: Mistakes Tenants Often Make for three more, including early possession and free rent structuring.
Moving In — and Beyond
A good advisor relationship doesn't end at signing. Once you've moved in, your advisor can stay on as a resource for area vendors, help resolve issues with the property or management, and support space planning as your business grows. If your needs change down the road — more headcount, a new location, a lease coming up for renewal — that same advisor is already familiar with your business and can help you develop the next plan rather than starting from scratch with someone new.
