Frequently Asked Questions
Variance thresholds?
Institutional standard: ±3% portfolio variance = normal. ±5% = warning. ±10% = investigation required. Property-level: ±5-10% normal; ±15%+ warrants detailed review.
Common causes?
Revenue miss: occupancy below plan, collection issues, rent concessions. Expense overrun: unexpected CapEx, insurance spike, vendor inflation. Tax reassessment, legal, professional services spikes. Each root cause requires different response.
Response?
Monthly trending to spot emerging variance early. Quarterly budget re-forecasts. Property-level investigation for any >10% variance. Portfolio-level dashboard for executives. Action plans documented and tracked through resolution.
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.
