Real Estate

Buying, selling, investing we know this market from both sides of the deal. Lake property, investment acquisitions, and creative deal structures.


The Standard

Trustworthy. Hardworking. Honest. Fair. These aren't slogans they're the rule on every job. We've built a reputation on those four things and we protect it on every project.

Why Big Birch

Operators, Not Just Contractors

We've been on the tools, managed the subs, negotiated the deals, and held the paper. That full-stack experience is what separates us.

Integrated Perspective

As both licensed contractors and licensed real estate operators, we evaluate projects through every lens build cost, ARV, cash flow, and execution risk. That combination is rare.

Northland-Native

We operate specifically in Northern Minnesota and Wisconsin lake and rural markets. We know the contractors, the suppliers, the seasons, and the real estate dynamics in this region.

Accountability First

When we commit to a timeline or a number, we stand behind it. Every project gets a real person, a real plan, and real follow-through not a call center or an out-of-state crew.

Investor-Minded

Whether you're a homeowner, buyer, or investor, we think about how a project affects your bottom line. We don't spec what you don't need and we won't cut what you do.

Market Focus

We Operate Here.
We Don't Just Sell Here.

The difference between a generalist agent and an operator-agent is significant. We own and manage properties in this market. We run rehab projects here. We know what buyers want, what sellers worry about, and what a deal looks like when the numbers work.

Affiliated with Elite Realty in Champlin, MN. Licensed in Minnesota, Wisconsin licensure in progress.

"The best real estate advice comes from someone who's also a buyer, seller, and builder. That's the position we operate from every time."

Founder

Paul Michelizzi

Big Birch Building Co. exists because clients deserve one person who can evaluate a property, price a scope, pull the permit, and execute the build without passing the accountability to someone else.

I'm a licensed General Contractor in Minnesota and Wisconsin, a licensed Real Estate Salesperson affiliated with Elite Realty, and an active investor in the Northern MN market. I'm on every job. I pull every permit. The work is done right or it doesn't go out the door.

"Trustworthy, hardworking, honest, fair. Those four things are the filter for every decision we make."
