Fifty names. That's the whole prospecting list for a commercial broker working one submarket, and it's smaller than most people expect. A town of 200,000 has maybe a few hundred multi-tenant buildings that matter, and a few dozen owners behind them. You don't need a funnel of thousands. You need to know exactly who owns what, when the leases end, and who has held the building long enough to be thinking about what comes next.

Here's how to build that list, time the contact to a lease expiry, write the first email, and keep a slow, high-value pipeline moving.

Who buys commercial brokerage and how they pick

Three buyers matter. Building owners who need tenants or are weighing a sale. Tenants who need space and aren't sure what's out there. And investors looking to buy. Owners are the best first target because one relationship can bring a listing, a lease, and later a sale.

Owners choose brokers by trust and local knowledge. They want someone who knows what comparable space is leasing for within a mile, who the active tenants are, and who will actually return calls. A big firm's brand matters less to a family that has owned a 40,000-square-foot retail center for 25 years than a clear answer to "what would you do with my vacancy?"

Find owners who've held buildings for more than 10 years

Public property records list the owner of every parcel, along with the purchase date and often the mailing address. Start with your submarket and filter for multi-tenant office, retail and light industrial buildings. Sort by purchase date and keep the ones purchased more than ten years ago.

Long-hold owners are interesting for three reasons: they often have rents set well below market, they may have debt close to maturing, and many are approaching retirement or estate planning. Write down the entity name, then find the person behind it. LLC names can hide a family, and a quick search of state business records usually shows the registered agent and sometimes a principal.

Your target is about 50 owners. A broker named Jonah in a mid-size market might end up with: 18 retail center owners, 14 office building owners, 10 industrial owners, and 8 mixed-use. That's a month of careful outreach and a year of follow-up.

If the research feels slow, Rocketship can find owners and decision-makers by plain-English description and add them to your pipeline with the details it finds, so you aren't doing every lookup yourself. Launch includes 50 leads a month, which matches this kind of list almost exactly.

Lease expiry: the moment to reach out

A tenant lease that ends in 18 months is the most useful date in commercial real estate. Eighteen months out, an owner starts to think about renewal, re-tenanting, or selling with income in place. A year out, they feel pressure. Six months out, they are scrambling.

You can't see lease dates directly, but you can infer them. Tenants who moved in a certain year, press about a business opening, a building that lists a vacancy now, and your own knowledge of the market tell you more than you expect. When you meet an owner, ask. "When do your larger leases come up?" is a perfectly normal question and one they can answer in a sentence.

Keep a column in your sheet for "next important date." It might be a lease expiry, a loan maturity, or just the owner's birthday year if you know they're 70. Reach out when the date is within 18 months.

The first email to a building owner

Owners are not looking for a pitch about your firm. They want to know whether you understand their building. Mention the property and one fact about it, then make a small offer: an opinion on value or rent, with nothing attached.

Subject: 410 Fulton Street

Hi Mr. Brandt, I'm a commercial broker focused on the east side. Two similar retail spaces on Fulton leased in the last six months, one at $22 per square foot and one at $24, and I thought you might want to see how that compares with 410. I can send a one-page comparison with no obligation, or stop by if you'd prefer to talk in person. Would that be useful?

Jonah Reyes, Reyes Commercial, 15 Market St, Suite 200, Raleigh. Reply "stop" and I won't write again.

Only use comps you can back up. Don't make up numbers. A broker who sends a real comparison earns attention, and one who exaggerates is remembered for the wrong reason. Include your address and an opt-out line, as US commercial email rules require.

Owners of older buildings often respond to a letter or a call more than an email, and a paper letter followed by an email works well. Don't be put off by a slow reply. It's common for a good owner to take three weeks.

Mailing everyone instead of the 50 who matter

It's tempting to blast 2,000 owners. It doesn't work, because you can't give each one anything specific, and you'll burn your sending reputation. In commercial real estate, the cost of a wrong message is also higher: owners talk to each other, and you're working one market for decades.

Fifty carefully chosen owners, each with a note about their building, beats a thousand generic messages. If you can't say something specific about the property, you're not ready to contact that owner yet. Do a little more research first or move the name to a later list. See how to build a list without buying one for the general method.

Follow up and book the property tour

Three touches over six weeks is plenty. The second could be a new comp or a note about a tenant moving in nearby. The third is a plain check-in. After that, set a reminder to write again in four or five months, or whenever a date on your sheet comes up.

When an owner agrees to talk, ask to walk the building. A property tour gives you the vacancy, the condition, the parking, the tenants, and the owner's real story. Bring a short list of questions: what's working, what isn't, any tenants likely to leave, what they'd do if a buyer called tomorrow. Take photos and notes, and send a summary within a day. That summary is your first piece of work for them, and it's often what wins the listing.

The reply to a first email may reach you while you're on a roof. Rocketship's AI workers read the reply and book the call or tour on your calendar, from your own Gmail, so slow-moving owners don't cool off while you're out.

Track 50 owners, 4 conversations and 2 tours in 30 days

A sheet with: owner, property, last purchase date, next important date, first contact, replies, tours booked. Aim for 50 owners contacted, 8 to 10 replies, 4 conversations, 2 tours. Commercial deals are few and large: one listing agreement on a $3 million building at a 3 percent commission is $90,000, so a quarter with one signed listing is a very good quarter.

More for commercial brokers: residential agents and property managers

Residential agents will find getting clients as a real estate agent a useful contrast, and property owners who manage their own buildings may want the property management page. For the next owner type, business brokers follow a similar slow-cycle approach, and architects sell to the same landowners. See the AI workers for what runs on its own.

Fifty owners and a long sales cycle reward a person who never forgets to write. Rocketship finds the buyers, emails them from your own Gmail, follows up, and books the meeting on its own. Plans that get you customers start at $24.99 a month (Launch), and every monthly plan starts with a 7-day free trial, card required. Answering your existing number is included; a dedicated line is $5 a month.
