Whether you’ve been a landlord for years or are just starting to build your rental portfolio, knowing the language of real estate investing is essential. We at Adaptive Realty have put together a list of terms that investors should familiarize themselves with.

1. 1% Rule
This rule recommends that the monthly rental income be no less than one percent of what the property was purchased for. For example, if you buy a property for $200,000, the rent should be at least $2,000 per month. While this rule is just a starting point, it helps landlords filter out properties that may not generate enough income to cover expenses.
2. 1031 Exchange
A 1031 Exchange allows you to sell an investment property and reinvest the proceeds into another similar property, without paying capital gains taxes right away. This can help you grow your portfolio faster and keep more of your profits invested. There are strict rules and time limits involved, but for landlords looking to upgrade or scale, it can be a powerful tool.

3. Capitalization (Cap) Rate
The Cap Rate measures a property’s potential return based on its net income and market value. It is calculated by dividing the net operating income (NOI) by the property’s purchase price. For example, if your NOI is $10,000 and the property costs $200,000, the Cap Rate is 5%. A higher Cap Rate means better potential returns, but also potentially more risk.
4. 2% Rule
This is similar to the 1% Rule but uses a higher threshold. According to this rule, a rental property should generate monthly rent equal to 2% of the purchase price. For example, a $100,000 property should bring in at least $2,000 in rent. This rule is harder to meet in many markets but can help identify high-yield opportunities.
5. Cash Flow
Cash flow is the money you have left over each month after paying all expenses, including mortgage payments, taxes, insurance, and maintenance. Positive cash flow means your property is generating income. Negative cash flow means you are losing money every month. Monitoring your cash flow helps you stay profitable.
6. Cash on Cash Return
Cash on Cash Return is a way to measure how much profit you’re making based on the actual cash you invested. For example, if you invested $50,000 into a property and it brings in $5,000 per year in profit, your cash on cash return is 10%. This metric helps you compare different investments and decide where to put your money.

7. Net Operating Income (NOI)
NOI is the total income your property generates minus all operating expenses. It does not include mortgage payments or taxes. For example, if your property brings in $30,000 in rent and your annual expenses are $10,000, your NOI is $20,000. This number is crucial when evaluating a property’s value and return.
8. After Repair Value (ARV)
After Repair Value (ARV) refers to what a property is expected to be worth after renovations or repairs are completed. It’s important for landlords who are buying fixer-uppers or considering refinancing. Knowing the ARV helps you plan property renovation budgets and determine if the improvements will increase your property’s value enough to justify the cost.

9. Leverage
Leverage means using borrowed money to buy real estate. Most landlords use mortgages to finance their properties. Leverage allows you to control more property with less of your own money. For example, a 20% down payment on a $300,000 property is $60,000. You’re using $60,000 to control a $300,000 asset. While leverage can increase returns, it also increases risk if rental income does not cover loan payments.
10. Negative and Positive Cash Flow
Negative cash flow happens when your property costs more to maintain than it brings in from rent. For example, if when renting out the home, your monthly expenses are $2,000 but you’re charging tenants $1,800, you’re losing $200 each month.
On the other hand, positive cash flow means your rental income is greater than your expenses. This surplus can be used for repairs, savings, or investing in more properties.

11. Portfolio
Your real estate portfolio is the collection of properties you own. Managing a portfolio means balancing risk, cash flow, location diversity, and property types. A strong portfolio typically includes a mix of different property types and locations to reduce risk.
12. Rental Property Analysis
This is the process of evaluating a property’s financial performance. It includes calculating cash flow, Cap Rate, cash on cash return, and comparing expenses against income. Rental property analysis helps landlords determine whether a property is worth buying or keeping.
13. Accessory Dwelling Unit (ADU)
An Accessory Dwelling Unit is a smaller, separate living space on the same lot as a single-family home. Examples include basement apartments, garage apartments, or backyard cottages. ADUs allow landlords to increase rental income without buying new land. They can also boost property value.
14. Appreciation
Appreciation refers to the growth in a property's market value as time goes on. It can happen naturally due to market conditions or through improvements made to the property. While appreciation is not guaranteed, it can significantly boost long-term profits when you sell or refinance.
