About Landmark Realty

Landmark Realty Vertical Logo

Landmark Realty of Illinois, LLC was founded in July 2000 with a commitment to bring a new level of professionalism in Real Estate to Princeton and the surrounding Illinois Valley area. With a goal of becoming the most innovative full service real estate brokerage in north central Illinois, Landmark has obtained a commanding market position in a very short period of time.

With a vast array of experience in Real Estate, Business Management, Marketing, Agriculture and Sales, the owners of Landmark, Crystal Lilley (815-878-5459), and Janelle McCarter (815-252-7283), there is a reason that we are consistently #1 in sales and listings in the Princeton area.

Coupled with a skilled team of energetic Realtors, our office in Princeton is well staffed to handle the needs of selling your property or helping find the property you desire. With a commitment to equal opportunity and ethical business practices, Landmark Realty is ready to serve all buyers and sellers.

We are the only Princeton real estate company that is handicapped accessible, 100% female-owned, and closest real estate office to Interstate 80.  We are also a member of the Illinois Valley Association of Realtors and MRED multiple listing service reaching the local market as well as the Chicagoland area.
