Frequently Asked Questions
Industry benchmarks?
Multi-family: 10-14% of NOI. Office: 12-18%. Retail: 12-16%. Industrial: 8-12%. Hospitality: 10-15%. Benchmarks vary by state/jurisdiction. Higher taxes indicate either premium market or over-assessment opportunities.
Using benchmarks?
Flag properties 20%+ above benchmark for appeal consideration. Systematic benchmarking reveals weak points. Top portfolios: 5-8% tax-to-NOI savings through active appeals. Annual review essential.
Benchmark sources?
IREM (Institute of Real Estate Management). NMHC (apartment). BOMA (office). ULI (general). Yardi Matrix (apartment). CoStar (commercial). Each has portfolio-specific breakdowns.
How often should I rerun this?
Rerun this calculator whenever inputs change materially — new rent roll data, rate moves, loan balance updates, or quarterly operating data. For active deals, monthly refresh is typical. For stabilized assets under monitoring, quarterly is fine. Treat the output as a decision tool, not a one-time answer — market conditions evolve and so should your analysis.
