Expert Witness Services
A real estate expert witness is someone with specialized knowledge of property markets, management, transactions, or practices who is retained in litigation to form and explain opinions that a judge or jury wouldn’t be able to reach on their own.

Greg Libby has served as an expert witness in a range of commercial and residential real estate disputes, including, but not limited to, property management practices, lease and landlord/tenant obligation disputes, and broker/landlord liability matters.
A real estate consultant is typically engaged proactively to solve a business problem – for example, improving property management practices or evaluating an investment. A litigation consultant works behind the scenes for the legal team rather than in front of the jury. Much of the underlying knowledge is the same as an expert witness. An expert witness is engaged within the context of a legal dispute to provide independent opinions that can be submitted to a court or used in arbitration/mediation. Greg Libby offers all three types of engagements; see the Services page for the consulting side and the Expert Witness page for litigation support.
Attorneys and firms can start by reaching out directly with case details so Greg Libby can evaluate fit, conflicts, and availability. Contact Libby Consulting by phone or email to begin that conversation – Greg’s phone number is listed on the Contact page.

Rentable square footage is the total space a tenant pays rent on, while usable square footage is the space the tenant can actually occupy exclusively; the difference is typically made up of shared common areas. This distinction matters in commercial lease negotiations and disputes. Read the full breakdown on the blog, and reach out via the Contact page if a lease dispute involves this issue.
Yes. Libby Consulting’s services extend beyond traditional property management into broader facilities-related matters affecting real estate operations.
