Successful investing in private real estate takes more than deep pockets. Market expertise to underwrite properties and management experience to execute profitable business plans are critical too. Yet human traits can lead even the best private investors astray. Behavioral economics, the study of financial decision-making psychology, bares the subconscious biases that trigger real estate investment mistakes.

When applied to private equity real estate investing, Thaler’s research suggests investors should have a strict, methodical assessment process in place — an evidence-based framework to evaluate investments and control for hidden biases. That is how we work as private equity real estate managers at Origin Investments.

People are comfortable with things they know, a behavior that is known as familiarity bias. Choosing investments is similar to gambling in that it is decision making in the face of risk, and experiments show that people make gambling decisions based on the familiar — even when they have lower odds of winning.

Don’t let familiarity limit your private equity real estate choices, or increase your risk of pouring too many resources into too few deals. Instead, consider taking on partners to invest smaller amounts in more deals. Or include different types of properties in the mix, based in different geographic locations. Real estate funds can also deliver a diverse portfolio of assets with different risk profiles, while minimizing the overall risk posed by…
