Investments & Business Brokerage: NOI, Leverage, Depreciation & 1031

Real Estate Investments and Business Opportunity Brokerage is 2% of the Florida sales associate exam, usually a couple of questions. They test vocabulary (net operating income, cap rate, leverage), a few federal tax rules investors rely on, and one Florida point: selling a business for a fee is brokerage under Chapter 475.

Business opportunity brokerage needs a license

Florida's definition of broker in § 475.01 covers a person who, for compensation, sells, exchanges, buys, rents or negotiates the sale of business enterprises or business opportunities or any real property. So a sales associate who helps sell a restaurant, inventory and goodwill included, is doing licensed work. That work must go through the associate's employing broker, just as a home sale would.

Measuring an income property

Net operating income (NOI)

Effective gross income minus operating expenses (and reserves, if the market uses them). NOI is measured before any loan payments.

Capitalization rate

Converts income to value: value = NOI ÷ overall cap rate.

Debt-service coverage ratio (DSCR)

NOI divided by the annual debt service. It measures the borrower's ability to service the debt.

Debt yield

NOI divided by the loan amount, expressed as a percent. Lower debt yields indicate higher leverage.

Leverage: borrowed money magnifies results

Leverage is easiest to understand with numbers. Compare the same building bought with cash and bought with a loan. Worked example (all figures exact):

• A building costs $1,000,000 and produces NOI of $70,000. Bought for all cash, the return on the cash invested is 70,000 ÷ 1,000,000 = 7%.
• Now the investor borrows $750,000 at 6% interest-only, so annual debt service is 750,000 × 0.06 = $45,000. Cash flow is 70,000 − 45,000 = $25,000 on $250,000 of equity: 25,000 ÷ 250,000 = 10%. That is positive leverage, because the property earns more (7%) than the debt costs (6%).
• DSCR = 70,000 ÷ 45,000 = 1.5̅ (about 1.56). Debt yield = 70,000 ÷ 750,000 = 9.3̅% (about 9.33%).
• If NOI falls to $40,000, cash flow becomes −$5,000, a loss the all-cash buyer would never see. Leverage magnifies losses as well as gains.

Assessing the risks

The OCC's commercial real estate handbook names the risks that matter to investors too:

• Liquidity risk: the risk of being unable to meet obligations when they come due.
• Interest rate risk: rate changes can change capitalization rates and so a property's value. With floating-rate debt and fixed rents, rising rates squeeze repayment capacity.
• Market risk: the cyclical nature of real estate markets.

Federal tax rules investors use

• Depreciation. The recovery period is 27.5 years for residential rental property and 39 years for nonresidential real property. Residential rental means 80% or more of the gross rental income comes from dwelling units. Land is not depreciable, because it does not wear out. Real property may be depreciated using the straight line method. Example, ignoring the first-year convention: a $275,000 building basis ÷ 27.5 = $10,000 a year.
• Like-kind (1031) exchange. Exchanging real property held for business or investment solely for other like-kind real property defers the gain. If you receive money or non-like-kind property ("boot"), gain is recognized to that extent. Property held primarily for sale does not qualify. Deadlines: identify the replacement property within 45 days after transferring yours, and receive it by the 180th day, or by the tax-return due date if that is earlier.

Where this shows up on the exam

Real Estate Investments and Business Opportunity Brokerage is 2% of the exam (DBPR candidate booklet, January 2025). Expect a leverage or NOI item and a question on whether business brokerage requires a license.
