Multifamily properties at $1M feature common-area improvements, shared building systems, and per-unit components — all creating a rich landscape for cost segregation.

A $1M multifamily property — typically a 5-10 unit building — generates substantial accelerated depreciation through cost segregation. The study typically reclassifies $144K into shorter MACRS classes, producing approximately $53K in first-year tax savings. The economics are straightforward: spend $1,495 on the study, recover $53K in tax savings.
Multifamily properties offer unique reclassification opportunities that single-family rentals don't. Common-area improvements like hallway lighting, entry systems, mailbox installations, parking lot paving, shared laundry equipment, and security systems all fall into accelerated recovery classes. Add the per-unit components (kitchens, bathrooms, flooring) across 5-10 units, and the reclassifiable basis adds up quickly.
The passive loss rules work differently at this scale: investors with $1M+ in multifamily typically have enough rental income to absorb the accelerated depreciation deductions regardless of their AGI. And if you qualify as a Real Estate Professional (spending 750+ hours annually in real estate activities), the passive loss limitations don't apply at all.

A cost segregation study is an engineering-based analysis that reclassifies components of your property into shorter IRS depreciation categories (5, 7, and 15 years) instead of the default 27.5 or 39 years. This accelerates your depreciation deductions, reducing your tax bill in the early years of ownership.
Multifamily properties have per-unit components (kitchens, bathrooms, flooring, fixtures) plus common-area improvements (hallway lighting, entry systems, mailboxes, parking lots, laundry equipment, security systems). Both categories qualify for accelerated MACRS classification, making multifamily properties especially rich in reclassifiable components.
Yes. The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for property placed in service in 2025 and beyond. This means you can deduct the full amount of accelerated depreciation identified in your cost segregation study in year one.
