How to Analyze a Commercial Real Estate Investment

Commercial real estate investors typically evaluate several financial measurements rather than relying on purchase price alone. A property’s income, expenses, financing, occupancy, tenant profile and lease structure can all influence investment performance.

The Commercial Real Estate Investment Calculator above combines several commonly used financial metrics to provide a preliminary view of a property’s operating performance and financing.

Effective Gross Income

Gross potential income represents the income a commercial property could generate before accounting for vacancy or collection loss. Effective gross income adjusts that amount for expected vacancy and can also include additional property income.

Other income might include parking revenue, storage income, signage income, reimbursements or other recurring sources associated with the property.

Net Operating Income (NOI)

Net operating income is one of the most important measurements in commercial real estate. NOI represents the income generated by a property after ordinary operating expenses are deducted, but before mortgage principal and interest.

Operating expenses can include property taxes, insurance, maintenance, management expenses, utilities paid by the owner and other recurring costs necessary to operate the property.

Mortgage principal and interest are generally excluded from NOI because financing is analyzed separately.

What Is Cap Rate?

The capitalization rate compares a property’s annual net operating income with its purchase price or value.

Cap rate can be useful for comparing income-producing properties, but it should not be used as the only measure of investment quality or risk.

What Is Commercial Real Estate Debt Service?

Debt service represents the principal and interest payments required by a property’s loan.

This calculator estimates the mortgage payment using the purchase price, down-payment percentage, interest rate and amortization period entered above.

Commercial loans may have additional terms such as balloon payments, maturity dates, adjustable interest rates, lender fees or other provisions that are not reflected in a basic amortization calculation.

What Is DSCR?

The Debt Service Coverage Ratio, commonly called DSCR, compares a property’s NOI with its annual debt service.

A calculated DSCR above 1.00 indicates that the property’s NOI exceeds the estimated annual debt service.

For example, a DSCR of 1.30 means the calculated NOI is approximately 1.30 times the annual debt service.

A ratio below 1.00 means the calculated NOI would not fully cover the estimated loan payments.

Commercial lenders may establish their own minimum DSCR requirements depending on the loan program, property type, borrower, tenant profile and transaction. The calculator should therefore not be interpreted as predicting loan approval.

What Is Annual Cash Flow?

For purposes of this calculator, estimated annual cash flow before tax is calculated by subtracting annual debt service from NOI.

Actual investor cash flow may also be affected by capital expenditures, replacement reserves, tenant improvements, leasing commissions, income taxes and other property-specific items.

What Is Cash-on-Cash Return?

Cash-on-cash return measures estimated annual pre-tax cash flow relative to the cash initially invested in the property.

For this calculator, initial cash investment includes the down payment, closing or acquisition costs, and initial improvements entered by the user.

Cap Rate vs. Cash-on-Cash Return

Cap rate and cash-on-cash return measure different aspects of an investment.

Cap rate evaluates the property’s operating income relative to its value without considering the buyer’s financing structure.

Cash-on-cash return considers financing because loan payments affect the cash flow available to the investor.

Two buyers purchasing the same commercial property could therefore have the same property cap rate but different cash-on-cash returns because they used different down payments, interest rates or loan structures.

What Is Loan-to-Value Ratio?

Loan-to-value ratio, commonly abbreviated as LTV, compares the loan amount with the property’s purchase price or applicable value.

For example, financing 75% of a property’s purchase price produces an estimated 75% LTV.

Lenders may establish maximum LTV requirements depending on property type, loan program and borrower qualifications.

What Is the Operating Expense Ratio?

The operating expense ratio compares a property’s operating expenses with its effective gross income.

This measurement can help investors understand how much of the property’s operating income is being consumed by expenses.

Why Vacancy Matters in Commercial Real Estate

A property may have attractive scheduled rents but still perform poorly if space remains vacant or tenants fail to pay rent.

The calculator therefore allows you to enter a vacancy and collection-loss assumption rather than assuming the property collects 100% of its potential income.

Realistic vacancy assumptions should be based on the property, tenant roster, lease expirations, submarket and relevant market conditions.

Other Factors Commercial Investors Should Evaluate

Financial ratios are useful, but a commercial real estate acquisition should be analyzed beyond the calculator.

Investors may also need to evaluate property location, zoning, permitted use, tenant quality, remaining lease terms, lease expiration schedules, rent escalations, market rents, vacancy, deferred maintenance, capital improvements, environmental conditions and future market demand.

For leased properties, reviewing the actual leases is particularly important. Income can change materially when leases expire, tenants relocate, expense reimbursements change or operating expenses increase.
