The Smart Investor’s Move: Applying Cost Segregation to Your Multifamily Portfolio

Written by Amitav Chowdhury, Real Estate Tax Consultant | Sep 29, 2025 11:51:33 PM

For investors with multiple apartment buildings, cost segregation can be the difference between steady growth and accelerated wealth creation. By reclassifying assets into shorter depreciation schedules, you can unlock significant tax savings, boost cash flow, and reinvest more aggressively, all while staying compliant with IRS standards.

Why Cost Segregation Matters for Multifamily Investors

Apartment buildings are ideal candidates for cost segregation. Unlike single-use commercial properties, multifamily assets include a variety of components such as appliances, flooring, lighting, landscaping, gyms, and pools that qualify for accelerated depreciation.

When these elements are identified and reclassified into 5-year, 7-year, or 15-year categories instead of the standard 27.5-year schedule, investors can dramatically shift the timing of deductions. The result is more cash flow in the early years of ownership, when it is often most valuable.

At Acena, our approach combines engineering accuracy with tax expertise, ensuring that each study is both comprehensive and audit-ready. This gives investors confidence that the benefits they realize are backed by careful analysis and compliant documentation.

Portfolio-Wide Strategy

For investors holding multiple apartment buildings, the opportunity compounds:

  • Immediate cash flow: Accelerated depreciation delivers near-term liquidity that can be reinvested into additional acquisitions or improvements.

  • Retroactive benefits: Properties acquired or improved since 2018 can still qualify through a look-back study, capturing missed depreciation in the current year.

  • Tax optimization: Pairing cost segregation with strategies such as 1031 exchanges allows investors to defer gains while maximizing new deductions.

  • Scalability: Studies can be performed across an entire portfolio, multiplying the benefit and creating a consistent, strategic approach to tax planning.

Acena’s process is designed to scale with investor needs, whether the portfolio includes two properties or twenty. By applying the same level of precision across each asset, we help clients establish a repeatable framework for long-term growth.

Key Considerations

  1. Timing is critical – The earlier you conduct a study, ideally right after acquisition or renovation, the greater the impact.

  2. Work with experts – Engineering-based studies with audit-ready documentation are essential to ensure IRS compliance and lasting value.

  3. Understand recapture – Plan your hold period carefully. Recapture can be mitigated with strategies such as 1031 exchanges.

  4. Size does not limit you – While large properties deliver outsized results, even mid-sized multifamily assets often see 20 to 35 percent of their basis reclassified.

Acena’s brand promise is to deliver more than a report. We provide clarity, defensibility, and a pathway to stronger returns.

The Bottom Line

For multifamily investors, cost segregation is more than a tax strategy. It is a growth strategy. By unlocking accelerated depreciation across your portfolio, you create stronger cash flow, higher ROI, and greater reinvestment power.

That is the smart investor’s move.
