- Set Unusable Land % (wetlands, steep slopes, easements) to reduce gross area.
- Enter Roads & Infrastructure % and Required Open Space % from zoning requirements.
- Set Average Lot Size in square feet — larger lots yield fewer units but may command higher prices.
- Review Net Buildable Lots and Density per Acre.
- Use Net Lots in your pro forma revenue model and compare against zoning density limits.
