About Us
We are a team of local Arizona professionals dedicated to building relationships with and assisting investors in the Arizona real estate market. We provide trustworthy real estate financing and service to help real estate investors achieve their goals.
Real estate deals move fast, but traditional lenders are often slow, impersonal, and difficult to work with—making it hard to trust your financing and move forward with confidence. With 20 years of real estate investing experience and 7 years as a private lender, KlinkLoans builds direct relationships with decision-makers, offering flexible, competitive loan programs and clear communication to help you close deals and focus on what matters most.
Jean Klinkhamer
President & Fund Manager
Jean Klinkhamer has been active in Arizona real estate since 2002, working hands-on with investment properties across the state. Over the years, he’s bought, renovated, and sold numerous homes and managed rental properties — giving him a practical understanding of the challenges and opportunities that real estate investors and builders face.
Today, Jean uses that experience to help borrowers access the funding they need to move their projects forward through private, asset-based lending. Having been on both sides of the table as an investor and a lender, Jean knows what it takes to close quickly, communicate clearly, and structure loans that help borrowers succeed.
Outside of real estate, Jean and his wife enjoy spending time with their adult children and grandchildren, serving through their church and Young Life. Jean also enjoys hiking and he is currently hiking segments of the Arizona Trail.
