Variance Analysis
Variance analysis compares a property's actual income and expenses with its budget, its prior-year results or its original underwriting, and explains the differences. It shows where performance is off track and why, so asset managers and lenders can respond before a small gap becomes a lasting problem.
How to calculate a variance
Variance = Actual − Budget
Variance (%) = (Actual − Budget) ÷ Budget × 100
Example: A property budgeted $120,000 for repairs and maintenance this quarter and spent $150,000. The variance is $30,000, or 25 percent over budget. The asset manager asks the property manager to explain the overage, such as an emergency repair or higher contractor costs.
Why variance analysis matters
Budgets and underwriting are only useful if results are measured against them. Variance analysis shows which lines are driving performance up or down, so management attention goes where it matters.
Good variance analysis explains the cause, not just the number. A revenue shortfall could come from vacancy, concessions or collections, and each needs a different response. Most owners set thresholds, such as a percentage or dollar amount, above which a variance must be explained.
Lenders use variance analysis too, comparing actual performance with the underwriting at closing to see whether the loan is performing as expected.
Budget Variance vs. Underwriting Variance
A budget variance compares actual results with the current year's operating budget. An underwriting variance compares them with the assumptions made when the property was bought or the loan was made. The first guides day-to-day management, and the second shows whether the original investment case is holding.
How Smart Capital Center handles variance analysis
Smart Capital Center's AI agents read incoming operating statements, map them to the budget and the original underwriting line by line, and produce variance reports that highlight the largest gaps for the team to review.
Frequently asked questions
What is a good variance threshold?
Many owners and lenders require explanations for variances above a set percentage, a set dollar amount or both, so that small lines with large percentage swings do not create noise. The right threshold depends on property size and the owner's reporting standards.
How often is variance analysis done?
Most owners review variances monthly or quarterly as operating statements arrive, with a fuller year-end review against the annual budget. Lenders typically review variances when borrowers submit their periodic financial statements, which is often quarterly or annually. Large or unexpected variances usually prompt a call with the property manager before the next report.
What causes large variances in commercial real estate?
Common causes include unexpected vacancy or tenant defaults, concessions, one-time repairs, changes in property taxes or insurance premiums, utility costs, timing differences between months, and accounting reclassifications. A good variance report separates one-time items from trends that will continue into future periods.
