Choose Cost Segregation Authority when its proposal matches these needs
CSA Partners describes property-specific engineering work and coordination with CPA clients. Keep it on your shortlist when the proposed scope, support and delivery arrangements meet the property's needs.
Consider AE for this situation
Suppose you own several rental buildings and want reports delivered to your CPA ahead of the return deadline. You need separate fees and schedules for each property, a clear inspection plan and a way for your preparer to resolve report questions.
Consider CSA Partners when its engineering and CPA-coordination scope fits the portfolio. Consider AE when its standalone study quote and separately agreed implementation meet your needs. Ask for property-level schedules and a documented handoff rather than relying on a headline minimum.
AE can scope a standalone study and discuss separately contracted advisory or return work. Retain your existing preparer when that arrangement fits, and agree on the report handoff before work begins. Neither provider is the universal choice. A discovery call determines potential fit; detailed analysis follows an agreed engagement.
