Cost Segregation

Cost segregation is a tax strategy that accelerates depreciation deductions on a multifamily property by identifying specific components (fixtures, landscaping, site improvements) depreciable over 5, 7, or 15 years instead of the standard 27.5 years.

What it means in practice

A cost segregation study, performed by a specialized engineering firm, breaks an acquired property into its depreciable components. Items with shorter IRS-assigned lives (carpeting, appliances, landscaping, specific site improvements) are depreciated faster, producing larger early-year deductions.

Effect: accelerated depreciation reduces current-year income tax. Tradeoff: higher depreciation recapture tax at sale. Best suited for properties held 5+ years with high current income tax exposure.

Why it matters for LA multifamily

LA multifamily buyers often commission cost segregation studies post-acquisition to maximize near-term depreciation. Sellers should understand the math because it affects what the buyer can pay — more accelerated depreciation supports stronger underwriting of the asset.
