What is a Commercial Real Estate Financial Model?

A commercial real estate financial model is a structured representation of a property’s financial performance over a specified period, usually five to ten years. This model includes projections for revenue, operating expenses, financing costs, and various performance metrics.

Key Components of a Commercial Real Estate Financial Model

• Revenue Projections: Estimations of rental income and other revenue sources.
• Operating Expenses: Direct and indirect costs associated with property management.
• Financing Costs: Costs related to loans and debt servicing.
• Key Performance Indicators (KPIs): Metrics that assess the investment’s performance.
• Cash Flow Analysis: Assessment of cash inflows and outflows over time.

Important Metrics to Include

• Net Operating Income (NOI): Total revenue minus operating expenses, representing the income generated by the property.
• Capitalization Rate (Cap Rate): A measure of the expected return on an investment property, calculated by dividing NOI by the property’s value.
• Gross Rent Multiplier (GRM): A valuation metric calculated by dividing the property price by the gross rental income.
• Loan-To-Value Ratio (LTVR): The ratio of the loan amount to the property value, indicating financial leverage.
• Debt Service Coverage Ratio (DSCR): A measure of cash flow available to pay current debt obligations, calculated as NOI divided by total debt service.
• Operating Expense Ratio (OER): A ratio of operating expenses to effective gross income, indicating the efficiency of property management.
• Occupancy Rate: The percentage of leased space compared to total available space, reflecting demand and profitability.

How to Build a Commercial Real Estate Financial Model: Step-by-Step for Beginners

Step 1: Define Your Assumptions

Start by outlining the key assumptions that will drive your financial model. These should include:

• Property Purchase Price: The total cost to acquire the property.
• Rental Income: Monthly and annual rental income based on leasing agreements.
• Operating Expenses: Estimated costs for property management, maintenance, taxes, insurance, and utilities.
• Financing Terms: Loan amount, interest rate, term, and other relevant financing details.
• Market Metrics: Assumptions for growth rates, occupancy rates, and future expenses.

Example Assumptions

• Property Purchase Price: $1,000,000
• Monthly Rental Income: $10,000
• Operating Expenses: $3,000 per month
• Loan Amount: $750,000
• Interest Rate: 4%
• Loan Term: 20 years
• Occupancy Rate: 90%

Step 2: Organize your model

Organize your financial model in a spreadsheet for clarity and ease of use. Common sections to include are:

• Input Assumptions: A dedicated section for all key metrics.
• Revenue Projections: Detailed forecasts of rental income and other revenue sources.
• Operating Expenses: Breakdown of all operating costs.
• Financing Costs: Calculation of debt service and financing costs.
• Cash Flow Statement: Summary of cash inflows and outflows.
• Key Performance Metrics: Summary of important financial ratios and metrics.

Step 3: Prepare the input assumptions sheet

Set up an input assumptions sheet in your spreadsheet where all key metrics are clearly defined. This sheet will serve as the foundation of your model, making it easy to update and adjust assumptions without affecting the overall structure.

Step 4: Calculate Revenue Projections

To forecast your revenue, start with rental income:

1. Annual Rental Income:

Annual Rental Income = Monthly Rental Income ×12 

2. Effective Gross Income (EGI):

EGI = Annual Rental Income × Occupancy Rate 

Example Calculation

• Monthly Rental Income: $10,000
• Annual Rental Income:

10,000 × 12 = $120,000 

• Effective Gross Income (EGI) with 90% occupancy:

120,000 × 0.90 = $108,000

Step 5: Calculate Net Operating Income (NOI)

NOI is calculated as follows:

NOI = EGI − Operating Expenses 

Example Calculation

Assuming monthly operating expenses of $3,000:

• Annual Operating Expenses:

3,000 × 12 = $36,000 

• NOI:

108,000 − 36,000 = $72,000 

Step 6: Calculate Capitalization Rate (Cap Rate)

The Cap Rate helps investors evaluate the potential return on an investment. It is calculated by dividing NOI by the property value:

Cap Rate = NOI / Property Value ​

Example Calculation

Cap Rate = 72,000 / 1,000,000 = 0.072 or 7.2% 

Step 7: Calculate Gross Rent Multiplier (GRM)

The GRM provides a quick estimate of a property’s value based on rental income. It is calculated by dividing the property price by gross rental income:

GRM = Property Price / Annual Rental Income ​

Example Calculation

GRM = 1,000,000 / 120,000 ≈ 8.33 

Step 8: Estimate Financing Costs

Calculate your loan payments using the loan amount, interest rate, and loan term.

Step 9: Calculate Debt Service Coverage Ratio (DSCR)

The DSCR indicates the property’s ability to cover its debt obligations. It is calculated as follows:

DSCR = NOI / Total Debt Service ​

Example Calculation

• Total Annual Debt Service:

4,545.52 × 12 = $54,546.24 

• DSCR:

DSCR = 72,000 / 54,546.24 ≈1.32 

Step 10: Calculate Loan-To-Value Ratio (LTVR)

LTVR measures the amount of financing compared to the property value, indicating the level of financial risk:

LTVR = Loan Amount / Property Value ​

Example Calculation

LTVR = 750,000 / 1,000,000 = 0.75 or 75% 

Step 11: Calculate Operating Expense Ratio (OER)

OER measures the proportion of operating expenses to effective gross income, reflecting property management efficiency:

OER = Operating Expenses / EGI  ​

Example Calculation

OER = 36,000 / 108,000 ≈ 0.333 or 33.3% 

Step 12: Calculate Occupancy Rate

The occupancy rate indicates how much of the available space is currently leased. It is calculated as follows:

Occupancy Rate = Leased Space / Total Space ×100 

Example Calculation

Assuming you have a total of 10,000 square feet and 9,000 square feet leased:

Occupancy Rate = 9,000 / 10,000 × 100 =90% 

Step 13: Create a Cash Flow Statement

The cash flow statement summarizes all cash inflows and outflows over time. Organize it into sections:

1. Cash Inflows: Include total revenue from rentals and other sources.
2. Cash Outflows: Include operating expenses, financing costs, and any other costs.

Example Cash Flow Summary

Step 14: Perform Sensitivity Analysis

Conduct sensitivity analysis to understand how changes in key assumptions affect your financial projections. Test various scenarios, such as:

• A higher or lower occupancy rate.
• Changes in rental income.
• Variations in operating expenses.

Step 15: Review and Refine Your Model

Once your initial model is complete, review it for accuracy and logical flow. Ensure that all calculations are correct and that inputs are clearly defined. Seek feedback from industry peers or financial advisors to identify areas for improvement.

Step 16: Use the Model for Decision-Making

Now that you have a comprehensive financial model, leverage it for decision-making. Whether considering new investments, refinancing options, or property management strategies, your model can provide valuable insights.

Example Scenarios for Decision-Making

1. Investment Analysis: Evaluate potential new properties using your model.
2. Refinancing Options: Assess the impact of lower interest rates on cash flow.
3. Cost Management: Identify areas for reducing operating expenses to increase NOI.
