In commercial real estate, underwriting is a critical process with zero room for error. A thorough and accurate underwriting process can lead to successful, profitable investments, while even small mistakes can turn promising opportunities into financial setbacks. Despite technological advancements, professionals still fall into common traps that compromise their analysis. This guide will explore the most frequent underwriting mistakes and how to avoid them.

1. Miscalculating Cash Flow Projections

The most significant errors occur in cash flow assumptions. Small mistakes in estimating rental income or operating expenses can quickly turn a profitable deal into a money-losing investment.

Common Cash Flow Mistakes:

• Overestimating income by assuming overly optimistic occupancy rates or unrealistic rent growth.
• Underestimating operating expenses, especially maintenance and capital expenditures.
• Overlooking hidden costs like tenant improvement allowances, leasing commissions, and unexpected repairs.

Solution: Data-Driven Analysis

The key to avoiding cash flow mistakes is using data-backed projections rather than relying on overly optimistic assumptions. Successful investors:

• Rely on actual historical performance data.
• Account for market-specific vacancy rates and factor in all operating expenses, including hidden ones.
• Automated tools like Cactus can instantly extract and analyze real rent rolls and operating statements.

2. Ignoring Market Context

A property does not exist in isolation, yet many analysts fail to account for the broader market context. This lack of perspective often leads to mispriced assets and overlooked risks.

Market Analysis Pitfalls:

• Relying on outdated cap rates that fail to reflect current market conditions.
• Using unverified broker-provided data.
• Ignoring emerging trends and relying too much on historical data.
• Using static models that can’t adapt to changing conditions.

Solution: Real-Time Market Data

Modern underwriting platforms like Cactus offer automatic integration of real-time market data, which ensures:

• Access to current market comps and trends.
• Real-time cap rate adjustments.
• Tracking of relevant economic indicators.
• Automatic flags for outlier assumptions.

3. Flawed Debt Service Coverage Ratio (DSCR) Analysis

Errors in DSCR calculations can derail financing or create high-risk leverage positions. Despite its importance, many analysts make basic DSCR mistakes.

Common DSCR Mistakes:

• Using static interest rate assumptions.
• Ignoring specific DSCR requirements for different property types.
• Failing to stress-test debt coverage under various market scenarios.
• Misaligning projections with lender guidelines.

Solution: Automated DSCR Verification

Using modern underwriting platforms eliminates these risks by:

• Automatically testing multiple interest rate scenarios.
• Flagging DSCR issues in real-time.
• Suggesting adjustments to meet lender requirements.
• Providing instant sensitivity analysis for different scenarios.

4. Underestimating Capital Requirements

Inadequate capital planning often leads to failed deals. Whether due to deferred maintenance or future replacement needs, underestimating capital expenses can quickly turn an otherwise substantial investment into a losing one.

Common Capital Planning Oversights:

• Assuming stabilized performance without considering necessary improvements.
• Underestimating costs for value-added projects.
• Neglecting to include long-term replacement reserves.
• Ignoring market-specific capital requirements.

Solution: Comprehensive Capital Analysis

Advanced underwriting platforms can help investors:

• Track capital requirements systematically.
• Compare costs against industry benchmarks.
• Project future capital needs accurately.
• Factor capital reserves into cash flow analysis.

5. Leverage Miscalculations

Incorrect loan-to-value (LTV) calculations can affect financing terms and ultimately impact investment returns. Many analysts still use outdated methods to assess leverage.

Common LTV Mistakes:

• Relying on static property valuations.
• Ignoring lender-specific requirements for leverage.
• Failing to stress-test leverage scenarios under different conditions.
• Overlooking market-specific LTV standards.

Solution: Automated Leverage Analysis

Modern underwriting tools provide:

• Real-time updates to property valuations.
• Automatic LTV calculations and verification.
• Instant comparisons against lender requirements.
• Comprehensive testing of leverage scenarios.

Breaking Free from Traditional Underwriting Practices

Most underwriting errors stem from reliance on outdated, manual processes like spreadsheets, which:

• Introduce human errors through manual data entry.
• Limit scenario testing capabilities.
• Use outdated market data.
• Waste time on routine calculations.

• Eliminate manual data entry.
• Process multiple scenarios instantly.
• Integrate real-time market data.
