Trailing Twelve Month (TTM)

Trailing twelve month is the 12-month period ending at a recent date — standard reporting period for multifamily financials during sale diligence. More current than calendar-year reporting.

What it means in practice

TTM financials capture the most recent year of actual performance. Useful for buildings with seasonality or recent operational changes that wouldn't show in prior-year financials. Buyers typically request TTM plus 2-3 prior calendar years.

Why it matters for LA multifamily

LA multifamily due diligence typically includes TTM financials alongside prior-year data. TTM shows the most recent operating picture — useful when the building is in transition or when calendar-year data is stale.
