Work worth pointing at

Selected by Unified Women’s Healthcare over the largest firms in Chicago

Unified Women’s Healthcare, LP — the nation’s largest physician practice management company dedicated solely to women’s health, with providers serving over 3 million patients a year across 22 states and DC — chose TAG to handle 20 medical office relocations and renewals across Illinois, selecting a boutique firm over several of the largest brokerages in the market. Nine relocations, renewals or subleases are complete to date, with more in process.

1891 Financial Life — a new office and a building sale in the same engagement

A 130-year-old insurance organization rebranded in 2021 and wanted to move out of the building it owned in Mt. Prospect into something more modern and more attractive to the talent it was hiring. TAG found them space in Schaumburg and, while that search was under way, found a buyer for the Mt. Prospect property — within one month of listing, at exactly the price TAG had predicted.

E&M Strategic Development — hotel development sites

TAG previously represented this hospitality development firm on the land purchase for a Holiday Inn Express and Suites in Elkhorn, Wisconsin. In March 2022 we assisted with the property purchase for a Homewood Suites by Hilton in Skokie, Illinois — a 143-room extended-stay hotel with a sky bar and event space, plus 13,000 rsf of street-scape retail that TAG is also listing.

Questions clients ask Bill

What should I consider when deciding between leasing or purchasing industrial or warehouse space?

When deciding whether to lease or purchase industrial or warehouse space, consider how long you plan to occupy the property, your available capital, and the total cost of occupancy. Purchasing can provide the opportunity to build equity and benefit from future appreciation, while leasing may offer greater flexibility as your business grows or changes. You should also consider the level of control you want over the property, your responsibility for maintenance and capital expenses, and the impact of financing and interest rates on a purchase. Ultimately, the decision should align with your long-term business strategy and whether investing capital in real estate makes more sense than putting that capital back into the business.

What factors besides rent should I be considering when negotiating an office lease?

There are many factors to consider when negotiating an office lease, and the best lease is the one that gives you the right combination of cost, flexibility, and protection. In addition to the more concrete financial aspects of the lease such as rental rate, annual rate escalations, months of abatement (free rent), tenant improvement allowance, and securitization, you can negotiate renewal rights, expansion rights, and termination rights. Depending on certain factors, you can also often negotiate items such as parking, signage, after-hours HVAC costs, and access to some building services or amenities.

When is the right time to do a sale-leaseback — as a buyer, and as a seller?

A sale-leaseback can be a powerful strategy for both a business owner and a buyer when the real estate represents significant value but owning the property is not essential to the long-term business strategy. For a seller, it may make sense when you want to maximize the value of the real estate, unlock cash from it, or continue operating from the same location without retaining ownership.

For a buyer, it can reduce the amount of capital required to acquire the business, preserve liquidity for growth, pay down debt, and allow more resources to be invested in the operating business rather than tied up in real estate.

What should I know when I’m preparing to sell? And when I’m preparing to buy?

When preparing to sell commercial real estate, it’s important to understand the property’s current market value, gather financial and property information, review existing leases and operating expenses, and identify any issues that could affect the sale. You should also consider the timing of the sale, potential tax implications, and whether improvements or other preparation could increase the property’s value or marketability. When preparing to buy commercial real estate, start by clearly defining your business and investment goals, determining your budget and financing options, and evaluating the property’s location, condition, income potential, and future value. In either case, understanding the market, knowing the numbers, and having the right professionals involved early can help you make informed decisions and avoid costly surprises.

What hidden costs should I expect when leasing office space?

Even if the lease is considered Gross, where the tenant pays for property taxes, insurance & maintenance as part of the rental rate, there can still sometimes be utility costs, phone & data costs, as well as costs for additional items such as parking, after-hours HVAC, or janitorial services. Other things to consider with all leases are costs for moving, furniture, phone & data wiring and set up, as well as architectural and construction costs, if the tenant is paying for the buildout. Furthermore, every lease requires some form of upfront securitization from the tenant. A tenant representative helps identify all upfront costs, negotiate who is responsible for them, and ensure their client understands the full cost implications of the lease before signing.

What is the difference between gross rent and net rent?

In a triple net lease (NNN), the tenant pays a net rent plus their proportionate share of the taxes, insurance and maintenance. In a single net lease (N), the tenant typically pays for base rent plus taxes, whereas the landlord covers maintenance & insurance.

In a gross lease, the tenant pays one set fee. The landlord pays for taxes, insurance, utilities, and maintenance (CAM) out of that money. In a modified gross lease, some utilities may not be included.
