Federal & State Credit Matrix

Eligibility Secrets: What Qualifies & What Doesn’t

A. Building Selection Criteria

Target properties with hidden potential:

• “Contributing Structures”: Buildings in National Register districts (even if individually unlisted)

• Pre-1936 Construction: Federal cutoff for most commercial properties

• Facade Retention: 75%+ exterior preservation required

• Disqualified Properties: Religious buildings, moved structures, reconstructed demolitions

B. Substantial Rehabilitation Test

Calculating the magic number:

• Expenditure Threshold:

  • Commercial: Exceed greater of $5,000 or adjusted building basis

  • Residential: 50%+ of acquisition cost (state-specific)

• Qualified Expenses:

  • Structural repairs

  • HVAC/plumbing/electrical

  • Accessibility upgrades

  • Site work (limited)

• Excluded Costs:

  • Acquisition

  • New additions

  • Furnishings

Application Process Demystified (3-Phase System)

A. Part 1: Preliminary Evaluation

Critical pre-purchase steps:

• Historic Certification: Secure National Register verification (6-18 months)

• Financial Feasibility Study: Project cost vs. credit projections

• Secret Tactic: Use “Pending Listing” status to lock eligibility pre-closing

B. Part 2: Rehabilitation Plan Approval

Designing for compliance & profit:

• The 20% Rule: Dedicate 20% budget to character-defining features (windows, facades, flooring)

• NPS Secret: Prioritize “preservation over restoration” for faster approvals

• Case Study: Cincinnati’s Union Terminal secured $170M via phased rehabilitation

C. Part 3: Final Certification

Post-renovation requirements:

• Documentation Package:

  • Before/after photos

  • Architectural drawings

  • Expense audits

• Compliance Traps:

  • Unapproved material substitutions

  • Undocumented change orders

  • Labor misclassification

Advanced Financial Engineering Strategies

A. Credit Monetization Pathways

Converting paper credits to cash:

• Direct Use: Offset developer’s tax liability (5-year carryback/20-year carryforward)

• Syndication: Sell credits to investors at $0.85-$0.95/dollar (average 22% IRR)

• State Transfer Programs: Montana’s 90% refundability vs. Georgia’s non-transferable credits

B. The “Basis Boost” Loophole

Maximizing depreciation:

• Standard Approach: Reduce depreciable basis by credit amount

• Pro Tactic: Retain full basis using “lessee pass-through” structure

• Savings Impact: $1.2M additional depreciation on $5M project

C. Credit Stacking Techniques

Layering incentives:

1. Federal/State HTCs (20-45%)

2. New Markets Tax Credits (39%)

3. Opportunity Zone Funds (capital gains deferral)

4. Energy Efficiency Credits (IRC §179D)

• Case Example: Detroit’s Book Tower secured 78% combined subsidies

Compliance Landmines & Solutions

A. Documentation Pitfalls

Audit-proofing your project:

• Time-Stamped Photography: Required for all “character-defining features”

B. Recapture Triggers

*Avoiding 5-year clawbacks:*

• Prohibited Actions:

  • Material exterior alterations
