About us
A fully integrated real estate company, from concept through long-term operation.

GreenMars is a fully integrated real estate company delivering complex housing, mixed-use, and commercial projects from concept through long-term operation. We bring site sourcing, financing, design, construction, commercial brokerage (through GreenMars Commercial Real Estate), leasing, and property operations together, with a focus on attainable rental homes and homeownership opportunities.
We believe housing should give people room to move forward. A rental home should leave room to save. A first home should offer a practical starting point for building equity and putting down roots.

Making that possible starts long before a home is listed. It takes thoughtful use of land, integrated design and planning, efficient construction, and a team that understands how those decisions work together. That is what we are building at GreenMars.
What we do
What GreenMars does
Housing we deliver
We create rental and ownership housing, including micro-apartments, compact condominiums, and cluster-style communities. Our focus is on practical homes that meet everyday needs at more attainable price points.
From start to finish
Our work spans finding sites, evaluating project economics, securing financing and approvals, and coordinating construction. Bringing these capabilities together helps us manage costs and make decisions with the whole project in view.
Long-term property operations
Through our affiliated property management company, our work extends into leasing and ongoing property operations. Connecting development with the experience of running a property helps us consider how homes will function after construction is complete.
Our approach
What makes GreenMars different
Attainable pricing starts with how we build
We work to reduce the cost of delivering housing through efficient layouts, appropriate density, and coordinated execution. Our goal is to make attainable pricing part of the project’s economics from the beginning.
One connected development process
Land, financing, permitting, construction, and operations all influence the cost of a home. We bring these functions together to reduce the extra costs and coordination problems that can arise when each phase is handled separately.
A focus on smaller, practical homes
Micro-apartments, compact condominiums, and cluster housing are central to our approach. These formats let us use land and building space efficiently while creating more options for people seeking a manageable rental or a first home.
Housing impact with a durable business model
We believe attainable housing and sound financial performance can support each other. The savings we find in design and construction do two jobs: they help keep housing costs down, and they keep each project financially sound so we can keep building.
A commitment to more housing
Our work includes advocating for changes that make it easier to add housing. We support reducing unnecessary barriers to development so more builders can help meet the need.

Our team
The people behind GreenMars
GreenMars was founded by Nate Green and Chris Marshall to make attainable housing easier to build and easier to find.
That goal shapes our work today. Our team brings together development, financial planning, engineering, construction management, commercial brokerage, accounting, leasing, and property operations. We approach housing as a connected responsibility, from the first assessment of a site to how the homes work day to day for the communities they are part of.

How we work
How GreenMars works
- 01
Evaluate the opportunity
We assess a site’s housing potential, development requirements, and financial feasibility. The aim is to identify a housing plan that responds to local needs and can be delivered responsibly.
- 02
Plan the project
We coordinate design, financing, permitting, and construction planning. Decisions about layout, density, and building methods are considered together because each affects the final cost and use of the homes.
- 03
Build and prepare for occupancy
We carry the plan through construction and coordinate the transition into sales or leasing. Pricing, eligibility, availability, and timing are specific to each community.
- 04
Support ongoing operations
For rental properties, our affiliated property management company handles leasing and property operations. This connection keeps the practical needs of residents and properties part of our development thinking.

FAQ
Frequently asked questions
What does GreenMars do?
GreenMars is a fully integrated real estate company. We create rental and ownership housing, and we bring together the planning, financing, construction, commercial brokerage (through GreenMars Commercial Real Estate), and operational capabilities needed to turn a site into homes.
How does GreenMars make housing more attainable?
We focus on the decisions that drive development costs: land use, home size, construction methods, financing, and coordination between project phases. Improving those factors helps us pursue more attainable rents and purchase prices.
Does GreenMars build both rental homes and homes for sale?
Yes. Our work includes rental apartments and homes for purchase, with a focus on compact, efficient housing formats.
Does every GreenMars property have income restrictions?
Requirements vary by property and program. Check the information for the specific community to understand any income limits, buyer qualifications, or other eligibility requirements.
Does GreenMars use housing subsidies?
Our approach emphasizes attainable pricing through efficiency. Some projects also use public assistance or housing programs, so funding structures and requirements should be understood at the individual property level.
