- Statewide 9% LIHTC (most common): 9% LIHTC + Washington State Housing Trust Fund + HOME.
- 4% LIHTC + bonds: 4% LIHTC + WSHFC bonds + state Housing Trust Fund.
- Permanent supportive housing: WA HTF + Section 811 PRA + Health Through Housing + 9% LIHTC.
- Seattle-area affordable rental: Seattle Housing Levy + 9% LIHTC + state HTF + WSHFC bonds.
- Mixed-income (workforce): 4% LIHTC + WSHFC bonds + local trust fund + state HTF.
- First-time homebuyer: Home Advantage + House Key Opportunity DPA + MCC.

- 25% PAB financed-by test: for bonds issued after December 31, 2025, materially expanding the pipeline of 4% LIHTC deals that can be supported per dollar of bond volume cap.
- Permanent OZ designations: Qualified Opportunity Zone designations gain permanence; Rural OZ provisions may apply in qualifying portions of the state.
- Section 45L / 179D termination (June 30, 2026): Developers pursuing energy-efficient construction should accelerate placed-in-service dates.
