Commercial Real Estate Accounting in 2026

What Owners and Operators Need to Watch

The commercial real estate market has spent the last few years bracing for bad news. Now, halfway through 2026, the picture is more mixed — some parts of the market are genuinely stabilizing, while others are just getting to the hard part. For owners, investors, and the finance teams supporting them, that mix creates a long list of accounting and tax issues that can't be put off until year-end. Here's what's actually on the table right now.

1. The Debt Maturity Wall Hasn't Passed — It's Just Changed Shape

An estimated $875 billion in commercial and multifamily mortgage debt is scheduled to mature in 2026, and more than $1.5 trillion will come due across 2025–2027 combined. That's a slight improvement from 2025's total, but "improvement" is relative — rates are still well above what many of these loans were originally underwritten at, and lenders are underwriting new deals more conservatively than they did a decade ago.

For accounting and finance teams, this isn't just a treasury problem. Loan modifications, extensions, and recapitalizations all carry real accounting consequences — debt classification, going-concern disclosures, and covenant compliance tracking all get more complicated when a loan gets restructured instead of simply paid off. If a property is carrying debt that matures in the next 12–24 months, now is the time to have your books, rent rolls, and trailing financials in a condition that supports a refinancing conversation — not after the lender asks.

2. Office Is a Tale of Two Markets — and South Florida Is the Exception

Nationally, office remains the most distressed property type, with CMBS office delinquencies having touched record highs earlier this year. But there are real signs that lenders are moving past "extend and pretend" toward actually resolving troubled loans, and distressed office sales have picked up meaningfully in 2026.

South Florida, though, is telling a different story. Miami-Dade office rents have been setting records, with newer boutique and "trophy" buildings pushing well past $200 a square foot. That divergence matters for how you think about asset-level accounting: national benchmarks and impairment assumptions that make sense for a Midwest office tower may not apply to a well-positioned Brickell or Boca building — and vice versa. Valuation and impairment testing needs to be market-specific, not headline-driven.

3. Permanent Bonus Depreciation Changed the Tax Math

This is probably the single biggest tax development for real estate owners this year. The 2025 tax legislation made 100% bonus depreciation permanent for qualifying property, reversing what had been a scheduled phase-down toward 20% by 2026. For anyone who has been putting off a cost segregation study because the benefit seemed to be shrinking, that calculation has flipped.

A cost segregation study typically reclassifies 20–35% of a commercial property's depreciable basis into shorter-lived categories that now qualify for full first-year expensing. On a $10 million property, that can mean several million dollars of accelerated first-year deductions instead of decades of straight-line depreciation. There's also a new provision — Qualified Production Property under Section 168(n) — that allows immediate expensing of the manufacturing-use portion of certain nonresidential buildings, and a firm sunset (construction beginning by June 30, 2026) on the enhanced Section 179D energy-efficiency deduction. None of this happens automatically; it requires a study and a plan, ideally before year-end tax planning turns into a scramble.

4. Property Tax Season Is Here — and the Appeal Window Is Short

Florida's TRIM notices go out in August, and the Value Adjustment Board appeal deadline typically falls about 25 days later — mid-to-late September. If you own commercial property and think your assessed value is out of line with the market, this is a hard deadline, not a soft one. Miss it, and you're locked in for another year regardless of how strong your case would have been.

This is a good moment to have someone actually compare your TRIM notice against comparable sales and your own operating numbers, rather than assuming the county got it right. Non-homestead commercial property in Florida is also subject to its own 10% annual assessment cap, which is worth understanding if you're trying to project next year's operating expenses.

5. Insurance Costs Are Still a Line Item to Watch

Florida commercial property insurance remains among the most expensive in the country because of hurricane and coastal exposure, though there are early signs of stabilization following the state's insurance market reforms. For owners, that means insurance is no longer a "set it and forget it" line in the operating budget — it needs to be revisited annually, factored into CAM reconciliations and expense pass-throughs, and modeled explicitly in refinancing and acquisition underwriting rather than assumed flat from last year.

6. Lease Accounting (ASC 842) Mistakes Are Still Showing Up in Audits

Years after ASC 842 took effect, the same handful of errors keep surfacing in audit findings: embedded leases buried inside service contracts (IT hosting agreements, equipment service deals) that never get identified as leases; misclassification between operating and finance leases; and discount rates that are inconsistent or undocumented. Each of these can force a restatement, and they tend to surface at the worst possible time — during a lender review or an audit, not during a routine internal check.

The fix isn't complicated, but it does require discipline: a periodic review of service contracts for hidden lease components, clear documentation of the judgment calls behind lease classification and discount rates, and treating lease accounting as an ongoing process rather than a once-a-year cleanup.

7. Office-to-Residential Conversions Bring Their Own Accounting Complexity

With office distress persisting in many markets, conversions to residential use continue to accelerate nationally — driven partly by tax incentives at the local and federal level. Conversions aren't just a construction and zoning project; they trigger real accounting questions around asset reclassification, capitalized costs versus expensed costs during the conversion period, and how existing debt and depreciation schedules carry forward (or don't) once the use of the property changes. Anyone evaluating a conversion should be modeling the accounting and tax implications alongside the construction budget, not after it's finalized.

8. The Talent Gap Is Pushing Firms Toward Automation — Carefully

Survey data from across the industry keeps landing on the same two numbers: a large share of real estate accounting teams cite manual, administrative work as their biggest daily challenge, and a similarly large share of finance leaders say they're struggling to find qualified accounting talent. That combination is why more owners and operators are turning to AI-assisted tools for reconciliations, CAM calculations, and reporting.

The caution here is that automation is only as good as the data feeding it. Tools that promise faster close cycles still depend on clean lease data, accurate expense coding, and a human who understands the property well enough to catch what doesn't look right. AI is a real productivity gain — but it's not a substitute for someone who actually knows the portfolio.

The Bottom Line

None of these issues exist in isolation. A property facing a 2026 loan maturity is also the one that needs an accurate valuation, a clean set of lease schedules, an up-to-date insurance number, and a property tax appeal filed on time — all at once. That's exactly the kind of work a fractional CFO or outsourced accounting team is built for: someone who's watching all of these threads at the same time your leasing broker, your lender, and your property manager are each focused on their own piece of it.

If any of this sounds like it applies to your portfolio, it's worth a conversation before the next deadline sneaks up on you.
