About Landmark United LLC

Built on Trust, Opportunity, and Real Relationships

Landmark United LLC is a family-led land company helping property owners explore real options for selling land while helping qualified builders and developers find off-market lot opportunities that match their buying criteria.

Vacant Land • Infill Lots • Builder Lots • Development Opportunities • Off-Market Land

Our Story

Why We Started Landmark United

Landmark United LLC was created around a simple belief: landowners deserve a clearer, more respectful way to understand and sell their property, and builders need a more consistent way to find quality land opportunities.

Many property owners have vacant land, inherited parcels, infill lots, or multiple lots they no longer want or know what to do with. At the same time, builders and developers are constantly looking for land that fits their criteria, price targets, and growth plans.

Landmark United exists to help bridge that gap.

We are not trying to be another generic land buyer website. Our goal is to build a company known for integrity, transparency, follow-through, and win-win outcomes. We want sellers to feel heard, respected, and informed, and we want builders to feel confident that the opportunities we bring are reviewed with professionalism and care.

What We Do

A Smarter Bridge Between Landowners and Builders

For Landowners

We help landowners submit vacant land, infill lots, inherited land, and developable parcels for review. Sellers do not need to know everything about zoning, utilities, access, or buildability before reaching out. We start with the information available and help create a clearer path forward.

  • Submit land for review
  • Share location, timing, and desired price
  • Discuss possible next steps
  • Understand whether buyer demand may exist
  • Move forward without pressure
Submit Your Land

For Builders and Buyers

We help qualified builders, developers, and land buyers share their buying criteria so we can better understand what they are looking for. Our goal is to identify land opportunities that may fit their target locations, lot requirements, price range, timing, and development needs.

  • Submit buying criteria
  • Define target markets
  • Share your land buy box
  • Review potential opportunities
  • Build long-term lot flow

Meet the Founders

Meet the People Behind Landmark United

Landmark United is built by real people with real business experience, real estate knowledge, family values, and a long-term vision. Our founders bring different strengths to the company, but share the same commitment to integrity, clear communication, and doing what we say we are going to do.

Jack Oyhancabal — Landmark United LLC Co-Founder

Jack Oyhancabal

Co-Founder & Strategic Vision

Jack brings decades of business ownership, relationship-building, and contractor-focused experience to Landmark United LLC. After more than a decade owning and operating health clubs, he learned that people remember how you make them feel and that great businesses are built on trust, service, and follow-through.

In 2007, Jack founded a contractor-focused insurance brokerage, where he has worked closely with builders and contractors for years. That experience gives him a unique perspective on the land business because he understands that every construction opportunity begins with the right piece of property.

Jack believes Landmark United can help solve a real problem for both sides of the market: landowners who need a clearer path to sell vacant land, and builders who need a steady pipeline of quality land opportunities at numbers that make sense.

Guided by faith, family values, integrity, and transparency, Jack's goal is to help build Landmark United into a company known for doing what it says, treating people fairly, and creating win-win outcomes for sellers and builders.

Great businesses are built on trust, relationships, and doing what you say you are going to do.

Luke Leydon — Landmark United LLC Co-Founder

Luke Leydon

Co-Founder, Growth, Systems & Opportunity Development

Luke is focused on helping Landmark United build the systems, relationships, and technology needed to grow with professionalism and consistency.

Drawn to businesses that create long-term value, Luke sees land as an opportunity to solve real problems for property owners while helping create lasting value for the family and the communities Landmark United serves. He believes Landmark United is about much more than buying land. It is about building a company that can stand the test of time.

Luke's strengths include building relationships, improving systems, solving problems, leveraging technology, and helping create a better experience for both sellers and buyers. He is passionate about learning every part of the land business, from evaluating properties and understanding local markets to building processes that allow the company to serve more people with clarity and efficiency.

For Luke, being part of a family business means building something that lasts beyond individual transactions. His goal is to help Landmark United earn a reputation for honesty, transparency, responsiveness, and always doing the right thing.

Success is not measured only by the properties we buy. It is measured by the relationships we build and the reputation we earn.

Our Values

The Values That Guide Us

01

Integrity

We believe in doing business the right way, even when no one is watching.

02

Clear Communication

Land transactions can be confusing. We believe sellers and buyers deserve straightforward, honest communication.

03

Respect for Sellers

Many properties have personal, financial, or family meaning. We treat every seller with patience and respect.

04

Builder-Focused Thinking

We understand that builders need land opportunities that make sense from a location, cost, timing, and development standpoint.

We believe in doing what we say we are going to do and communicating clearly along the way.

Why People Work With Us

Six things we're serious about.

Property-first review

Every submission is looked at on its own merits — parcel, location, and condition before pitch.

Builder-focused criteria

We screen opportunities against how builders and developers actually buy land.

Educational approach

We explain what we see so sellers and builders can make informed decisions.

Nationwide land opportunity review

We review land opportunities across the U.S., market by market, one parcel at a time.

Clear communication

Plain answers. No jargon, no pressure tactics, no vague promises.

No-pressure process

You share what you have. We review. You decide what — if anything — happens next.

For Sellers

Landowners Deserve a Clearer Path

Selling land can feel overwhelming, especially when the property has been owned for years, inherited through family, or never professionally evaluated. Many sellers do not know the zoning, utility status, access details, parcel number, or whether the land is buildable.

That is okay.

Landmark United gives sellers a place to start. We review the information available, ask the right questions, and determine whether the property may fit current buyer demand. Whether a seller chooses to move forward or not, our goal is for every conversation to leave them more informed, more confident, and treated with respect.

Submit Your Land for Review

For Builders

Builders Need Lot Flow. We Help Source Opportunities.

Builders and developers need consistent access to land opportunities that match their target locations, lot requirements, price range, and development strategy. Public listings are often limited, competitive, or picked over. Many of the best opportunities start before a property is widely marketed.

Landmark United works to understand each buyer's criteria so we can better evaluate whether future land opportunities may be a fit. Our goal is to build relationships with serious buyers who value speed, clarity, professionalism, and proper due diligence.
