Calculated Output Metrics

Estimated Buildable Lot Yield 99 Residential Lots
Gross Finished Lot Revenue $9,405,000.00
Net Usable Buildable Land 19.50 acres (849,420 sq ft)
Gross Density Yield 3.96 Lots / Gross Acre

Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
Net Buildable Area = Gross Acres × (1 - Infrastructure Loss %) | Lot Yield = Net Area / Minimum Lot Size

Step-by-Step Mathematical Derivation

1
Acre to Square Foot Conversion

One acre equals 43,560 square feet. Gross Square Footage = Gross Acres × 43,560.

2
Infrastructure Efficiency Deduction

Subdivisions lose 18% to 28% of gross land to public road rights-of-way, stormwater detention basins, wetlands buffers, and open space mandates: Net Usable Area = Gross Sq Ft × (1 - Infrastructure Loss%).

3
Lot Yield Formulation

Estimated Lot Yield = floor(Net Usable Area / Minimum Lot Size). For 19.5 net acres: 849,420 sq ft / 8,500 sq ft = 99 finished single-family lots.

Frequently Asked Questions

What is the typical infrastructure loss percentage for land subdivisions? +
Standard single-family subdivisions typically lose 20% to 25% of gross acreage to street rights-of-way, curbs, utility easements, and stormwater detention basins. Mountainous or wetland terrain can exceed 35%.
What is the difference between paper lots and finished lots? +
Paper lots are legally approved and platted on paper by the municipality, but have no physical roads or utilities. Finished lots are fully graded with asphalt roads, curbs, water, sewer, and electric stubs ready for home framing.
