A $5M multifamily apartment complex generates $720K in accelerated depreciation — enough to shelter years of rental income or offset substantial ordinary income.

At $5M, a multifamily apartment complex (typically 20-50 units) is one of the most cost-segregation-friendly investment types. The combination of per-unit components (kitchens, bathrooms, flooring, fixtures across every apartment) and common-area improvements (lobbies, hallways, parking structures, laundry facilities, fitness rooms, pools) creates an exceptionally rich pool of reclassifiable building elements. The study typically identifies $720K in accelerated depreciation.
The economics at this scale are compelling: $720K in accelerated depreciation generates approximately $266K in first-year tax savings against a study cost of $2,495. That's a 107x return. For syndicators and fund managers, cost segregation at this level is standard operating procedure — the accelerated depreciation is a key component of the investor returns they market to limited partners.
Multifamily properties also benefit from common-area site improvements that are often overlooked: parking lot paving and striping, sidewalks, retaining walls, irrigation systems, exterior lighting, signage, mailbox clusters, dumpster enclosures, and playground equipment. These 15-year property components can represent 8-12% of the total depreciable basis on their own.
| Price | Accelerated | Tax Savings | Study Cost | ROI |
|---|---|---|---|---|
| $1M | $144,000 | $53,280 | $1,195 | 45x |
| $5M | $720,000 | $266,400 | $1,295 | 206x |
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.
