Flag Lot

A flag lot is a parcel of land configured with a narrow strip of frontage — resembling a flagpole — that connects a larger, set-back building site to a public road. The shape is a practical response to landlocked or irregular land configurations, providing legal access where a standard lot layout is not possible.

In valuation, flag lots often present comparability challenges, as their irregular shape, limited street visibility and shared or narrow access can affect marketability relative to standard lots. Appraisers must assess whether the market recognizes a value difference and support any adjustment with paired sales or market data.

Loan originators and buyers should confirm that access is legally documented and that the lot configuration meets local zoning and lender requirements before proceeding with financing.
