1. Cash Flow

Cash flow refers to the net income a property generates after all operating expenses are deducted from rental income. Positive cash flow means you're making money each month, while negative cash flow means you're losing money. 

Understanding cash flow is critical for rental property owners who want consistent income from their investments.

2. Net Operating Income (NOI)

Net Operating Income is your property's total income minus operating expenses, not including mortgage payments or taxes. It helps you evaluate the profitability of an investment property based purely on its performance. 

High NOI usually indicates a well-managed and potentially valuable property. Learn how to calculate your NOI for the best results.

3. Capitalization Rate (Cap Rate)

Cap rate is a metric used to assess the return on investment of a rental property. It is calculated by dividing NOI by the property’s purchase price. 

For example, a property generating $10,000 in NOI and costing $200,000 would have a 5% cap rate. A higher cap rate often indicates a better return, although it may also come with more risk.

4. Gross Rent Multiplier (GRM)

Gross Rent Multiplier is another way to evaluate rental properties. It compares the property’s price to its annual rental income. For instance, if a property costs $300,000 and produces $30,000 in annual rent, the GRM is 10. 

Lower GRMs generally suggest better investment opportunities, but the metric does not consider expenses, so it should be used alongside other calculations.

5. Appreciation

Appreciation is the increase in property value over time. Some properties naturally appreciate due to market conditions, development in the area, or renovations. 

While cash flow gives you monthly income, appreciation builds long-term wealth. Along with appreciation, it's always good to learn about depreciation and property value.

6. Equity

Equity is the portion of the property you truly own. It is the difference between your property’s market value and the remaining mortgage balance.

Building equity over time allows you to access financing options such as home equity loans or cash-out refinancing for future investments.

7. Leverage

Leverage in real estate refers to using borrowed capital to buy a property. Most investors use mortgages to fund purchases, which allows them to invest in real estate without paying the full amount upfront. 

When done wisely, leverage can increase your return on investment. However, overleveraging can increase financial risk, especially if market conditions change.

8. Vacancy Rate

The vacancy rate is the percentage of time a rental property is unoccupied. High vacancy rates mean lost income, while low vacancy rates indicate steady tenant demand. 

As a landlord, understanding this term helps you assess how well your property is performing compared to the market average as well as lower vacancy rates.

9. Debt-Service Coverage Ratio (DSCR)

DSCR measures your ability to pay off debt with the property’s income. A DSCR of 1 means your property earns just enough to cover the mortgage. Anything above 1 is considered healthy. Lenders often require a DSCR of at least 1.25 for investment properties before approving loans.

10. Operating Expenses

Operating expenses are the day-to-day costs of running a rental property. These include property management fees, maintenance, repairs, insurance, utilities (if paid by the owner), and property taxes. Tracking operating expenses is necessary for calculating NOI and cash flow.

11. Return on Investment (ROI)

ROI is a measure of profitability. It is typically expressed as a percentage and calculated by dividing the net profit by your total investment cost.

A higher ROI indicates a more profitable investment. However, ROI does not factor in time or risk, so it should be evaluated alongside other performance indicators.

12. 1031 Exchange

A 1031 exchange allows investors to defer paying capital gains taxes when they sell one investment property and reinvest the proceeds into another "like-kind" property. 

This strategy is often used by experienced investors to grow their portfolio while deferring tax liabilities.

13. Capital Expenditures (CapEx)

Capital expenditures are large, infrequent expenses that improve the value of a property, such as roof replacement, HVAC installation, or major renovations. Unlike regular maintenance, CapEx investments are planned and often require budgeting in advance.

14. Title Insurance

Title insurance protects the buyer and lender from financial loss due to defects in the title, such as unpaid taxes or liens. It is a one-time cost during closing and provides peace of mind that the property’s ownership history is clear.

15. Escrow

Escrow refers to a neutral third party holding funds or documents during a transaction. In real estate, escrow accounts are also used by lenders to collect and manage funds for property taxes and insurance premiums.

16. After Repair Value (ARV)

ARV is the estimated value of a property after renovations or improvements. This is especially important for fix-and-flip investors, as it helps estimate potential profits. Understanding ARV also helps in deciding whether a renovation is worth the investment.

17. Property Management

Property management involves handling the day-to-day operations of a rental property, including tenant screening, rent collection, maintenance, and lease enforcement.

Whether done independently or outsourced, effective property management keeps your investment running smoothly and protects its value, from getting tenants to report repairs to collecting rent.

18. Rent Roll

A rent roll is a document listing each unit in a rental property, the tenants occupying them, lease terms, and rent amounts. It offers a quick snapshot of your rental income and is essential for property analysis and during the sale of multifamily buildings.

19. Zoning

Zoning refers to local government rules about how land can be used, such as residential, commercial, industrial, or mixed-use. Understanding zoning laws is essential when buying a property or planning renovations, especially if you intend to change its use.

20. Due Diligence

Due diligence is the process of thoroughly evaluating a property before finalizing the purchase. 

This includes reviewing financial records, inspecting the property, researching the neighborhood, and verifying legal documents. Skipping due diligence can lead to costly surprises later.
