Decision Frameworks Built for Real Estate Investors

The five named frameworks below answer recurring investor questions in two minutes or less. They are the decision tools we use internally on every WeCostSeg engagement and the basis of how we explain results to clients.

• Framework

  The WeCostSeg 3-Bucket Decision Framework

  A cost segregation study is worth doing when the property meets one of three buckets: basis above $300K with a bonus-eligible placed-in-service date, a qualifying STR with material participation, or a REPS-qualified taxpayer with W-2 or active income to offset.

• Framework

  The STR Qualification Matrix

  Four pass-fail criteria that determine whether a short-term rental qualifies for nonpassive loss treatment under Reg. 1.469-1T(e)(3)(ii): average guest stay 7 days or less, material participation under one of the seven Reg. 1.469-5T tests, ownership during participation, and contemporaneous hour documentation.

• Framework

  The Bonus Depreciation Timing Window

  Three timing rules from OBBBA and IRS Notice 2026-11 determine which bonus rate applies: acquisition date (binding contract), placed-in-service date, and the optional 40% election for the first tax year ending after January 19, 2025.

• Framework

  The 5-Year Audit Defense Standard

  Every WeCostSeg study includes five years of written audit defense covering methodology, asset classifications, and engineering conclusions, aligned to the thirteen Principal Elements of a Quality Cost Segregation Study in IRS Publication 5653.

• Framework

  The CPA Coordination Protocol

  A three-touch handoff between cost seg engineer and tax preparer: preliminary analysis shared before engagement, draft report shared for review before delivery, and Form 3115 prep coordinated when prior-year basis is affected.
