Free Commercial Properties DCF Analyzer (2026)

Commercial DCF requires tenant-by-tenant modeling with specific lease terms, expiration dates, and renewal assumptions. You must account for tenant improvements, leasing commissions, free rent periods, and expense recoveries. Commercial properties also use longer hold periods (7-10 years typical) and lower discount rates (6-12%) compared to residential (8-12%).

Core office buildings in primary markets (Class A, high occupancy, credit tenants) typically use 6-8% discount rates. Value-add office properties (vacancy, upcoming lease rollovers, needed renovations) warrant 9-12%, while opportunistic plays (major repositioning, lease-up, development) use 13-18% to reflect higher risk and execution requirements.

Budget TI costs as lump-sum capital expenditures in the year each lease expires or renews. Use market TI rates per square foot for your submarket and asset class—typically $20-60/sf for office renewals, $40-100/sf for new leases. Also include leasing commissions (4-6% of total lease value) and rent-free periods (3-6 months for new tenants) as cash flow impacts.

Use in-place rents for currently occupied space under lease, then roll to market rents when each lease expires. This creates a realistic cash flow projection that captures lease rollover risk and potential upside. If in-place rents are below market, your NOI will grow as leases renew; if above market, expect compression when tenants renegotiate or vacate.

Take the stabilized NOI from year 11 (or your exit year) and divide by a market-based exit cap rate. For example, $500,000 NOI ÷ 7% cap rate = $7.14M terminal value. Then discount that future value to present using your discount rate. Use exit cap rates 0.25-0.75% higher than going-in cap rates to be conservative about future valuations.

Core commercial properties (stable, high-quality, low-risk) target 8-12% IRR. Value-add strategies (lease-up, renovation, re-tenanting) aim for 13-18% IRR. Opportunistic investments (ground-up development, major repositioning) require 18-25%+ IRR to compensate for execution risk. Compare your DCF-calculated IRR against these benchmarks to assess deal quality relative to risk profile.

Model recoverable expenses (CAM, taxes, insurance, utilities) as revenue line items that offset operating costs. For triple-net (NNN) leases, tenants reimburse 100% of expenses. For modified gross leases, calculate each tenant's pro-rata share of increases over a base year. Accurately modeling recoveries is critical—it can swing NOI by 15-30% compared to gross revenue assumptions.

Use 7-10 years for most commercial analyses, which aligns with typical investment fund lifecycles and provides enough time to execute value-add business plans. Shorter holds (3-5 years) work for quick repositioning plays with near-term exit triggers. Longer holds (10-15 years) suit core assets acquired for stable income, though forecasting accuracy diminishes beyond 10 years.

Include planned CapEx (roof replacement, HVAC upgrades, parking lot resurfacing) as negative cash flows in the specific years they occur. Budget ongoing CapEx reserves at $0.15-0.50/sf/year for building systems and common areas. Major one-time expenditures should be modeled separately based on engineering assessments and actual cost quotes rather than generic reserve assumptions.

Absolutely—commercial deals have multiple risk variables that can swing returns dramatically. Test sensitivity to discount rate (±1-2%), exit cap rate (±0.5-1%), rent growth (±1%), vacancy (±5-10%), and major lease renewal assumptions. Create a matrix showing how NPV and IRR change across these scenarios to understand downside risk and identify the variables that matter most to your investment thesis.
