Key Takeaways
- After-tax underwriting reveals the true investment return—depreciation can increase effective returns by 5-15%.
- Qualified cost seg firms perform physical inspections and follow IRS methodology—avoid desktop-only studies.
- Section 481(a) catch-up adjustments allow all prior-year missed depreciation to be deducted in one year.
- 1031 exchange is the most effective recapture mitigation—deferring all recapture and capital gains to the replacement property.
This recap consolidates the underwriting and decisioning frameworks for depreciation covered in Track 2. Test your understanding of after-tax analysis, cost segregation evaluation, and recapture planning.
After-Tax Underwriting Review
After-tax cash flow analysis adds depreciation, tax impact, and after-tax returns to the standard pre-tax pro forma. Cost segregation should be modeled during acquisition underwriting to quantify the incremental after-tax benefit. Rule of thumb: 25-30% reclassified × bonus rate × marginal rate = estimated Year 1 tax savings. Cost segregation breaks even on properties with building basis of $500K+ and is most valuable for investors with REPS status.
Study Evaluation and Implementation Review
Qualified cost seg firms employ licensed PEs, perform physical inspections, and follow IRS methodology. Study deliverables should include component-by-component breakdowns with legal citations. Look-back studies use Section 481(a) adjustments (Form 3115) to catch up prior-year missed depreciation in a single year. Coordinate between the cost seg firm and CPA with an 8-week lead time before filing deadlines.
Recapture Planning Review
Depreciation recapture is taxed at up to 25% (Section 1250) or ordinary rates (Section 1245 personal property). Recapture applies to depreciation "allowed or allowable"—always claim depreciation. Mitigation strategies: 1031 exchange (defer all recapture), installment sale (spread remaining gain), charitable donation (eliminate), and step-up in basis at death. Cost segregation does not increase total recapture—the time value of accelerated deductions exceeds the incremental recapture cost.
Go / No-Go Decision Framework
Go Indicators
- ✓After-tax underwriting reveals the true investment return—depreciation can increase effective returns by 5-15%.
- ✓Qualified cost seg firms perform physical inspections and follow IRS methodology—avoid desktop-only studies.
No-Go Indicators
- ✗Commissioning a cost segregation study without coordinating with the CPA who will file the tax return: The CPA may not be familiar with cost segregation, may misapply the study results, or may fail to file Form 3115 for a look-back study—negating the benefit
- ✗Neglecting to account for depreciation recapture when evaluating the cost segregation ROI: The investor overestimates the lifetime tax benefit because accelerated depreciation increases recapture upon sale, partially offsetting the earlier savings

Common Mistakes to Avoid
Commissioning a cost segregation study without coordinating with the CPA who will file the tax return
Consequence: The CPA may not be familiar with cost segregation, may misapply the study results, or may fail to file Form 3115 for a look-back study—negating the benefit
Correction: Ensure the CPA is engaged from the beginning; the study firm and CPA should coordinate on deliverables, depreciation schedules, and form preparation
Neglecting to account for depreciation recapture when evaluating the cost segregation ROI
Consequence: The investor overestimates the lifetime tax benefit because accelerated depreciation increases recapture upon sale, partially offsetting the earlier savings
Correction: Model the full lifecycle including early-year savings, time value of money, and eventual recapture (or deferral via 1031 exchange) to calculate the true net present value of the study
