Here’s how the "One Big Beautiful Bill" (OBBBA)—sometimes just called the "Big Beautiful Bill"—benefits commercial property owners under the new law signed on July 4, 2025:
Key Benefits for Commercial Property Owners
- 100% Bonus Depreciation (Full Expensing)
- Owners can immediately write off the full cost of qualifying assets placed in service between January 20, 2025 and 2030.
- This accelerates depreciation, boosts cash flow, and enhances the economics of real estate investments, particularly when combined with cost segregation techniques.
- Expanded Section 179 Expensing
- For mid-size projects, up to $2.5 million can now be expensed immediately (with a $4 million phase-out), covering systems like HVAC, roofs, and security.
- Note: Traditional passive rental properties may not qualify for Section 179 unless operating as an active trade or business.3. Enhanced Qualified Business Income Deduction (Section 199A)
- The 20% pass-through deduction (applicable to many real estate operations) is now permanent; in some cases it has been increased up to 23%.
- Greater Interest Deductibility (Section 163(j) Relief)
- The bill revamps the limitation on deducting business interest by:
- Reintroducing depreciation, amortization, and depletion as add-backs to Adjusted Taxable Income (ATI), increasing the deductible amount.
- Switching the calculation to an EBITDA basis, which allows more interest to be deducted—especially beneficial for leverage-heavy real estate ventures.C
- Extension of Energy-Efficient Building Deduction (Section 179D)—with a Deadline
- Owners who start qualifying energy-saving construction before June 30, 2026 can still claim valuable commercial building efficiency deductions.
- Other Strategic Tax Opportunities
- The bill keeps 1031 like‑kind exchanges intact and maintains favorable capital gains treatment—important for deferring taxes during property reinvestments.
- It also bolsters affordable housing development by expanding Opportunity Zone benefits and the Low‑Income Housing Tax Credit (LIHTC).
Key Benefits for Mid‑Core Apartment Owners
- Permanent 100% Bonus Depreciation & Expanded Section 179
You can now immediately expense eligible property components (e.g., HVAC systems, appliances, roofing) instead of depreciating them over decades. Section 179 expensing jumps to $2.5 million (phases out at $4 million)
Example:
A 20-unit building purchased for $3M—assume $900K of systems (30%) are eligible. Instead of deducting a mere ~$32K per year (27.5-year schedule), you can write off the full $900K in year one, radically improving early cash returns.
- Permanent & Enhanced QBI Deduction (Section 199A)
Your rental income, if passed through via an LLC or partnership, can qualify for a 23% deduction, versus the previous 20%, with a smoother phase-out threshold
Example:
A building generating $500K in net rental income could save an extra ~$15K in taxes annually—pushing your effective tax rate even lower.
- Enhanced Interest Deductibility (Section 163(j))
Interest on financing traditionally subject to limits is now fully deductible if depreciation and amortization are excluded from the adjusted taxable income calculation
Example:
If you have a $2M loan at 5% (~$100K in interest), that entire amount may now be deductible—boosting after-tax returns.
- Affordable Housing Tax Credit Enhancements (LIHTC)
If your mid-core property qualifies as or includes affordable housing, you benefit from a 12% permanent increase in LIHTC allocations and a reduced bond threshold (from 50% to 25%), enabling more projects to pencil out
Example:
Converting part of your property to target income-qualified tenants could unlock tens of thousands in credits, significantly reducing development costs.
- Perks of Opportunity Zone (OZ) Investments
If your property is in a designated Opportunity Zone, you retain OZ tax advantages—and these are now permanent. That unlocks capital-gains deferral and potential basis boosts
Example:
Selling another property for a gain, you can invest into your OZ-located mid-core building and defer gains while benefiting from depreciation and QBI—amplifying returns and tax efficiency.
