Asking rent
The base rent a public listing states for a commercial suite, recorded with the date the listing was read. An asking rent is what the landlord or broker is marketing, not a signed lease, not an appraisal, and not proof the suite is available. When a listing states no rent, Fact Lease leaves the field blank (null in the data) and never estimates, rounds, or fills it in.
NNN vs full service vs modified gross
Lease structure labels such as NNN, full service (gross), and modified gross are recorded exactly as the listing states them. Fact Lease never converts one structure into another or adjusts a rent to a different structure, so compare like with like. When a listing does not state a structure, the field stays blank.
Dollars per square foot per year
The standard unit for comparing commercial asking rents ($/SF/yr). When a listing states a rent and a unit that convert, Fact Lease uses the annual per-square-foot figure in medians and charts; a monthly rent converts only when the listing also states the area and the published method allows it. A rent with no unit or no period is shown as stated and never forced into $/SF/yr.
Why a median is not published when n is below the minimum
n is the number of stated rents behind a median. A class, ZIP, or citywide median is published only when at least 5 stated rents convert to dollars per square foot per year. Below that level, Fact Lease shows n and the threshold instead of a dollar figure, and asks search engines not to index the industrial and flex pages until they qualify.
Comparing areas without inventing a submarket
Fact Lease does not draw broker submarkets or district lines. Compare areas by the ZIP codes listings state, and by building pages where a published property name or address already includes the place. Names such as Galleria or Energy Corridor appear only when the listings themselves state them, and a suburb is never inferred from a ZIP code alone.
