About 17 Mile

30+ Years of Experience in Real Estate & Wireless Infrastructure

At 17 Mile, we specialize in purchasing real estate with existing wireless assets—properties that house income-producing cell tower ground leases or rooftop antenna agreements with major carriers. We’re not brokers. We’re private investors building our own portfolio, and we have the capital, experience, and focus to move fast.

With over 30 years of combined expertise in both real estate and wireless infrastructure, we understand the unique complexities that come with these types of transactions. From navigating lease agreements to dealing with carrier requirements and land use considerations, we’ve seen it all—and we know how to get deals done without the usual delays or friction.

Fast, Reliable, and Fully Funded

We’re also well-funded and completely self-backed, which means we don’t rely on third-party financing to close. That allows us to move quickly when opportunities arise. When we say “CASH. SOLD. DONE.”—we mean it. If you’ve ever tried to close a deal like this through traditional channels, you’ll understand just how valuable that speed and certainty can be.
