What is Tenant Advisory?

Our team represents companies looking for new office space; to expand, extend or re-negotiate an existing lease; or to minimize a financial commitment through the sublease of surplus space. We work exclusively for tenants; we do not represent building owners, allowing for full focus on developing and executing the most beneficial real estate strategy possible for occupiers.

The Tenant Advisory Group assists clients in finding the right office space to fit their needs at the lowest cost. Office space is more than just an expense – it is a symbol of your brand, culture and values, contributes to the attraction and retention of top talent, and enhances productivity. We work with company management to understand both how you use real estate and what kind of space in what location will further your business’ success.

By identifying market trends and leveraging our knowledge of the Seattle and Bellevue office markets, our team generates competition between landlords, thereby maximizing value in lease negotiations. We serve office users from across the industry spectrum, from the world’s premier corporations to small businesses and start-ups seeking everything from corporate headquarters to back-office operation locations.

“Taylor and Joe worked with our best interests in mind throughout the process which started years before we actually occupied our new space. They listened well to our wants and kept their eyes open for a new space over several years. They continually respected our processes and honestly were a true pleasure to work with during this process. They were an important part of determining our space needs and examined all of the options with us prioritizing both our short and long term business needs. Their constant communication and transparency throughout the process allowed us to feel confident in the decisions we were making. I would highly recommend their team to help solve our office space needs moving forward.”

Kelly Long - Controller


“Tenant Advisory Group helped us grow our office from approximately 1,500 square feet to 35,000 square feet over a couple years. Recently, they created an opportunity for us to simultaneously move into a larger space that accommodated our immediate growth needs while eliminating our existing lease obligation by assigning it to a credible company. This seamless transition eliminated any overlap of paying on multiple lease locations and their ability to completely handle the intricacies of the transactions allowed our team more time to focus our efforts solving core business challenges. Every step of the way Sam and Taylor addressed the many challenges our needs presented with our interests at heart. They understood our objectives and executed a well thought out strategy in a way that maximized our value received in the negotiation process while also getting what we wanted done on a timeline critical to our team. I strongly recommend their team.”

Chris Heaslip - CEO


“Colliers Tenant Advisory Group did a great job for Inspur USA as we grew our local operation. We started our relationship with a conversational meeting where we described to them our immediate business needs and upcoming changes to our team. Colliers identified the best office spaces that aligned with our business goals and then negotiated the best deal possible on our behalf. Their ability to listen to our needs and present options that best fit those needs is what stood out about them. We will definitely be using Colliers Tenant Advisory Group the next time a commercial real estate need arises at Inspur”.

Jay Zhang - VP US Operations


"Taylor and the Colliers team have been flexible and understanding partners to us at Ripl as our growth path has zig-zagged through 4 office spaces and a couple growth periods. Taylor has been incredibly patient during times we've needed to look at sub-leases, long-term leases or just stay put for a few quarters and see what our company hiring plan turned out to be. We started working with them will just a few employees, and over 5 years they've helped us negotiate for great terms on different spaces and buildings. They really understand that with startups, there are a variety of factors on the timing of office space moves including hiring, fundraising, and solving for flex time and flex space needs. Taylor has treated every situation with us like it's no big deal, par for the course, and been a steady hand representing our interests and need for flexible options with building owners and managers. For growing companies that need advice, representation, advocacy and ultimately just understanding of what's different about real estate needs of a startup, Taylor and his Colliers colleagues totally get it."

Clay McDaniel - COO, Paul Ingalls - CEO


“Our organization enjoyed working with Colliers TAG team for our commercial real estate search. Their professionalism and best in class service made finding a first-class office space a successful process.

Their ability to answer questions quickly and build a strategy toward securing a space in a competitive real estate market was excellent.”


"The Colliers TAG team is strategic in their pursuit of exceeding my expectations. I loved working with them.”

I really appreciate their communication, openness, and professionalism. They are true consultants for my team, not your old-school traditional brokers.

How We Make a Difference

Coca Cola signed a 91-month deal on 20,777 square feet at a Bellevue CBD property. Shortly after occupying the space, organizational changes occurred that moved most of their critical staff off-site, leaving Coca Cola with only 15 employees occupying the space. This created internal stress, as the company updated their corporate standard for office space per employee, and the Bellevue location was immediately identified as an office that was out of compliance. While the rent was ignificantly below market, Coca Cola approached Colliers about assisting with a “right size” relocation for their critical staff, then recovering the maximum amount of rent for which they were liable at their CBD location.


> Understand the client’s needs in a relocation space using RUNCLEAR analysis
> Market the sublease space ASAP
> Identify relocation options
> Create leverage between relocation properties
> Execute a lease at relocation space
> Work with vendors for a smooth transition between spaces
> Recover as much rent from existing space in Bellevue CBD


Using the RUNCLEAR analysis, the Colliers team was able to identify the most important elements for Coca Cola in a relocation space, and after touring the market had three solid options. Throughout the proposal process, Colliers was able to leverage a below market deal for Coca Cola that created roughly $100,000 in savings at their relocation property.

By marketing their sublease space immediately, Colliers was able to structure a deal where a Subtenant was able to occupy half of the Coca Cola space almost immediately, saving Coca Cola roughly $500,000 on their rent before even considering relocating.

Avalara is a growing technology company focusing on sales tax automation. The company had multiple locations in the Seattle area as well as in other markets that it hoped to consolidate under one roof to a new Headquarters in Seattle. There were several significant challenges that Colliers faced as we began the process of exploring alternatives. The Seattle real estate market was becoming increasingly tight and large blocks of space were scarce. Further complicating the issue was finding space that allowed the company to retain its corporate culture allowing it to retain existing staff as well as attract new talent. Additionally the company was poised for substantial expansion with projections of growing by over 200% within 36 months.


> Negotiating an aggressive built in expansion schedule for Avalara which would allow them to space pocket significant blocks of space staggered out over the first 36 months of the term Market the sublease space ASAP
> Securing rights for further expansion within the building giving Avalara comfort that they will not be boxed in on their long term commitment
> Achieve above market capital for tenant improvements which will allow Avalara to construct space that achieves their goals of maintaining corporate culture and enabling them to attract top talent


Colliers is currently negotiating an aggressive built in expansion schedule for Avalara which would allow them to space pocket significant blocks of space staggered out over the first 36 months of the term. We are also securing rights for further expansion within the building giving Avalara comfort that they will not be boxed in on their long term commitment. We anticipate achieving above market capital for tenant improvements which will allow Avalara to construct space that achieves their goals of maintaining corporate culture and enabling them to attract top talent. Further, we have negotiated for substantial signage meeting the branding goals Avalara had set out to achieve.

Mulvanny G2 was three years away from termination option on its 63,000 square foot headquarters lease in Bellevue, WA and wanted to either design a new office building or mixed-use project where they could be the anchor tenant or refurbish to LEED specifications an older downtown Seattle building. Mulvanny G2’s management team were also in the process of rebranding the company as “MG2” which included a potential relocation back to Seattle to further their growing international reputation and enhance their ability to recruit young and creative architectural talent.


> In conjunction with MG2 leadership, Colliers created a unique comprehensive checklist comparing the positive and negative impact a relocation to Seattle or staying in Bellevue would have on the company culture and major clients
> Considering the limited time frame to design, permit and build an office building or mixed use project, the Colliers team focused and selected sites and developers who could meet our time frame
> Colliers team provided comprehensive net present value financial models of total lease and relocation cost of new construction finalist buildings compared to the refurbishment alternatives


Colliers was able to deliver an extremely affordable and under market long term lease in fully refurbished and LEED Gold certified creative office building known as 1101 2nd Avenue. In additional Colliers was able to create a cost sharing solution with new their new landlord that allowed them to exit their building in Bellevue prior to their lease termination which was important for the
rebranding. The selection of the refurbished building was also key to continued successful relationship with their long standing
customers including Costco Wholesale. As a result of their successful negotiation on their assignment, Colliers has been retained and successfully sublet the Portland office, and downsized the Washington DC office.

Pushpay had recently leased a small space on short term two (2) year term and were only 30 days from their initial public offering on the New Zealand Stock Exchange (NZX). The US division of the company had just relocated from San Diego and due to the pending IPO and cash infusion, needed to quickly ramp up hiring efforts to justify the anticipated investment. Their current Redmond WA location could not accommodate any further growth with their anticipated hiring efforts. They needed a solution to quickly accommodate a much larger presence in the US and attract the best new talent, while retaining current employees and enhance company culture.


> The Colliers team created an aggressive marketing strategy to sublease Pushpay’s current space in line with a targeted lease commencement date on a larger new space
> Carefully analyzed space options taking into consideration realistic expectations for the timing involved in each phase of the leasing process including selection of short listed properties, Request for Proposal and lease negotiations, space planning, permitting, construction and final occupancy
> Emphasized to prospective landlords that Pushpay’s required tenant improvements would be attractive to other tech users and would enhance the value of the suite and building even after Pushpay potentially outgrew the space..


Colliers was able to target and deliver on a space that achieved all goals of the client including talent attraction/retention, timeline, budget, and location. In addition, the Colliers team was able to successfully sublease their previous space to a subtenant with an occupancy timeline that aligned with Pushpay’s target occupancy date at the new location. The deal was completed at sublease rates that virtually eliminated their previous lease obligation which was Pushpay’s number one priority. In addition, the Colliers team was able to negotiate a flexible lease term that allowed for future growth and termination options should the landlord be unable to accommodate their growth.
