Unit count determines which per-unit metrics are meaningful and what financing options are available. Properties with 1–4 units qualify for conventional residential mortgages with lower down payments and better rates. Moving to 5+ units requires commercial financing with different underwriting criteria.
Detailed Explanation
Number of Units is the count of separate rentable units in the property. A single-family home has 1 unit; a duplex has 2; a fourplex has 4. This drives per-unit metrics like Price Per Unit, Revenue Per Unit, and Operating Cost Per Unit. Per-unit analysis is the standard method for comparing multi-family properties of different sizes. Residential financing (1–4 units) has different terms than commercial (5+ units).
