What is NOI?

Net Operating Income is the standard metric for valuing income-producing real estate. It's effective gross income minus operating expenses, but specifically excludes debt service and capex. NOI is the "apples-to-apples" income figure used to compare parks with different financing structures.

What's a healthy operating expense ratio?

Stabilized TOH-heavy parks usually run 30–40% operating expense ratio (OpEx ÷ EGI). POH-heavy parks run 45–55% because the operator absorbs home-side capex and turnover. Above 55% in a TOH-heavy park usually signals a problem: deferred maintenance catching up, a payroll bloat, or under-billed utilities.

Why does NOI per lot matter?

NOI per lot is the cleanest portfolio comparison metric. National averages cluster around $1,500–$2,500 per lot per year for stabilized parks. Over $3,000 is excellent; under $1,000 typically means under-rent or operational drag.
