Principle of Regression
Definition and meaning of Principle of Regression in real estate.
Principle of regression is an appraisal theory stating that the value of a high-end or superior property is pulled down when it is located near lower-value, inferior properties. This concept highlights the risk of over-building or over-improving a home relative to its surrounding neighborhood.
In more detail
When a homeowner builds an elaborate, expensive house in an area of modest, run-down homes, the value of that high-end house will likely suffer. Buyers shopping for a luxury home are rarely willing to purchase in a neighborhood where the surrounding properties are poorly maintained.
As a result, the appraiser will discount the value of the over-improved home to align more closely with local market norms. Investors use this principle to avoid pouring too much capital into renovations that the neighborhood cannot support.
