Question 1

What is NOI and why does it matter?

Accepted Answer

Net Operating Income (NOI) = Gross Rental Income − Operating Expenses. It's the most important metric for evaluating rental property performance because it shows how much cash the property generates before debt service. Lenders use NOI to calculate DSCR (Debt Service Coverage Ratio) and investors use it to calculate cap rate. Most real estate valuation conversations start with NOI.

Question 2

What expense categories should I include?

Accepted Answer

Standard operating expense categories: property management fees (typically 8-12% of gross rent), property taxes, insurance, maintenance and repairs, landscaping, utilities (if landlord-paid), vacancy allowance (typically 5-10%), and CapEx reserves. Exclude mortgage payments — those are below-the-line financing costs, not operating expenses.

Question 3

How do I show this chart in an LP update?

Accepted Answer

Show income and expenses as grouped bars by quarter or year, with NOI as either a third bar or an annotated line. Compare actuals to underwritten projections to show whether the deal is performing as expected. If expenses came in above budget in a specific category, call it out — LPs appreciate transparency and active management.

Question 4

What is a healthy expense ratio for rental properties?

Accepted Answer

A common rule of thumb is the 50% rule: operating expenses (excluding mortgage) should run roughly 50% of gross rent for a stabilized single-family or small multifamily property. For larger multifamily or commercial properties with professional management, expense ratios of 35-45% are common. Higher-expense markets (high taxes, older buildings) can push ratios above 55%.

Question 5

Can I show multiple properties on this chart?

Accepted Answer

Yes — use a grouped or stacked bar chart with one group per property, showing income and expenses side by side. For a fund with many properties, aggregate by property type (multifamily, retail, industrial) rather than individual assets. A portfolio-level summary with a drilldown to individual properties is the most useful format for LP quarterly reports.
