Commericial REal estate Glossary for Passive Investors: Cap Rate, NOI, DSCR and More

If you have ever sat through an investor webinar or read a deal summary, you have probably run into a wall of terms: cap rate, preferred return, waterfall, DSCR, K-1. As a busy professional looking at passive income, you do not need to underwrite a deal yourself. But you do need to understand what the sponsor is telling you.

This glossary explains the multifamily investing terms you will hear most often, in plain English. Bookmark it and come back whenever a number or phrase does not make sense.

These terms describe who does what in a syndication and how the investment is organized.

Syndication

Many investors pool their money to buy a property that would be too large to buy alone. An experienced team finds, buys and runs the property, while investors contribute capital. See our guide on how to invest in multifamily properties.

Sponsor

The company or team that organizes the deal, raises the money, secures the loan and carries out the business plan. The quality of the sponsor often matters more than the property itself.

General Partner (GP)

The active partner who makes the day-to-day decisions and is responsible for results. GPs earn fees and a share of the profits.

Limited Partner (LP)

A passive investor who provides capital without managing anything. An LP's liability is generally limited to the amount invested. Read more: Do You Have to Manage the Property if You Invest Passively?

Capital Stack

All the money used to buy a property, layered by who gets repaid first. Senior debt sits at the bottom (lowest risk, lowest return), followed by mezzanine debt, preferred equity and common equity at the top (highest risk, highest potential return).

Senior Debt

The main mortgage on the property. It is repaid first if the property is sold.

Preferred Equity

Equity that is paid ahead of common equity but behind all debt, usually at a targeted fixed return.

Common Equity

The last position to be paid, with the most risk and the most upside. Most LP investments are common equity.

Operating Agreement

The legal document that sets out each partner's rights, how decisions are made and how profits are distributed. Read it carefully before you invest.

Capital Call

A request for additional investor money after the original raise, usually to cover unexpected costs. Ask every sponsor how capital calls are handled.

No single number tells the whole story. Look at several together. For a deeper look, read IRR, Equity Multiple, Cash Return: Common Real Estate Return Metrics.

Cash Flow

What is left after all operating expenses and loan payments are paid. This is the source of investor distributions.

Distribution

A cash payment from the property to its investors, usually monthly or quarterly.

Cash-on-Cash Return

Annual cash flow divided by the money invested. If you invest $100,000 and receive $7,000 in a year, your cash-on-cash return is 7%.

Internal Rate of Return (IRR)

An annualized return that accounts for both the amount and the timing of every cash flow over the life of the investment.

Equity Multiple

Total cash returned divided by total cash invested. A 2.0x equity multiple means you received back twice what you put in. It does not show how long that took, so it is read alongside IRR.

Preferred Return (Pref)

A minimum annual return that LPs receive before the GP shares in profits. Ask whether it is cumulative (unpaid amounts carry forward).

Waterfall

The order in which cash is distributed. A typical waterfall returns capital and the preferred return to LPs first, then splits the remaining profit between LPs and GPs.

Promote

The GP's share of profits above the preferred return, earned for performance rather than for the capital it contributed.

Hold Period

How long the sponsor plans to own the property, often three to seven years. Your money is generally tied up for this entire time.

Liquidity

How quickly an investment can be turned into cash. Private real estate is illiquid.

Pro Forma

The sponsor's projection of future income, expenses and returns. It is only as reliable as its assumptions.

Sensitivity Analysis

A test showing how returns change if rent growth, occupancy, expenses or exit pricing come in worse than expected. A good sponsor shows you the downside case, not only the best case.

A property's value comes from the income it produces, so these terms appear in almost every investor update.

Gross Potential Rent (GPR)

The most rent a property could collect if every unit were leased at market rates.

Loss to Lease

The gap between what residents currently pay and what the same units would rent for today. A big gap can signal room for rent growth.

Concessions

Incentives such as a free month of rent used to attract residents. They reduce real income.

Physical vs. Economic Occupancy

Physical occupancy counts occupied units. Economic occupancy measures the rent actually collected. A property can be 95% occupied but collect far less if residents are not paying.

Effective Gross Income (EGI)

Rental and other income after subtracting vacancy, concessions and unpaid rent.

Operating Expenses (OpEx)

The ongoing cost of running the property, such as management, payroll, utilities, insurance, repairs and property taxes. Loan payments are not included.

Net Operating Income (NOI)

Income minus operating expenses, before loan payments. NOI is the most important number in commercial real estate because a property's value is largely based on it. See Investing in Apartment Buildings: Metrics You Need to Know.

Trailing 12 (T-12)

A month-by-month statement of the property's actual income and expenses over the last twelve months.

Rent Roll

A unit-by-unit list of who lives where, what they pay and when their lease ends. It confirms that the income a seller claims is real.

Unit Mix

The breakdown of unit types, such as studios, one-, two- and three-bedrooms.

Turnover and Make-Ready

Turnover is how often residents move out. Make-ready is the work needed to prepare a unit for the next resident. High turnover raises costs and vacancy.

Property Management

The team that handles leasing, maintenance, rent collection and resident relations. Strong management protects NOI. Read: Property Management Strategies for Apartment Investors.

Asset Management

Higher-level oversight by the sponsor: tracking results against the business plan, reviewing budgets and keeping investors informed.

Capital Expenditures (CapEx)

Spending on major improvements or replacements, such as roofs, HVAC systems or unit renovations.

Reserves

Cash set aside for unexpected expenses and planned replacements, so investors are less likely to face a capital call.

Deferred Maintenance

Repairs that previous owners put off. Finding it during due diligence is key to setting an accurate renovation budget.

Back to top ↑

Most multifamily properties are bought with a mix of investor equity and a loan. The loan terms tell you a lot about the risk.

Leverage

Using borrowed money to buy a larger property. Leverage can increase returns, and it can also magnify losses.

Loan-to-Value (LTV)

The loan amount divided by the property's value. A $7 million loan on a $10 million property is 70% LTV.

Debt Service

The principal and interest payments due on a loan.

Debt Service Coverage Ratio (DSCR)

NOI divided by annual debt service. A DSCR of 1.25 means the property earns 25% more than it needs to make its loan payments. A larger cushion is safer.

Amortization

The gradual repayment of loan principal through scheduled payments.

Interest-Only Period

A period when the borrower pays only interest. It improves near-term cash flow but does not reduce the loan balance.

Fixed-Rate vs. Floating-Rate Loan

A fixed rate stays the same for the loan term. A floating rate moves with a benchmark such as SOFR, so payments can rise or fall.

Rate Cap

A purchased contract that limits how high a floating interest rate can go.

Bridge Loan

Short-term financing used to buy and improve a property until it is ready for long-term debt.

Agency Debt

Loans backed by Fannie Mae or Freddie Mac, commonly used for stabilized apartment communities.

Recourse vs. Non-Recourse

With a recourse loan, the lender can pursue the borrower's personal assets after a default. A non-recourse loan generally limits the lender to the property, except for specific "bad boy" carve-outs such as fraud.

Refinance

Replacing an existing loan with a new one, often to get better terms or return capital to investors.

Prepayment Penalty

A fee charged for paying off a loan early.

Every deal has a plan for creating value. These terms describe the property and the strategy behind it. Also read The Benefits of Investing in Apartments.

Value-Add

Buying a property with room for improvement, upgrading units or operations, raising income and increasing the property's value.

Forced vs. Market Appreciation

Forced appreciation is value created by improving the property and its NOI. Market appreciation comes from the broader market, which no sponsor controls.

Stabilized Property

A property operating at healthy occupancy with steady performance, generally ready for long-term financing.

Lease-Up

The period when a new or newly renovated property is filling with residents.

Class A, B and C

Informal grades of property quality compared with the local market. Class A is the newest with top amenities, Class B is mid-age and well located, and Class C is older and usually needs more capital. Class B and C often offer the best value-add opportunities.

Workforce Housing

Apartments aimed at middle-income households such as teachers, nurses and tradespeople.

Student Housing

Apartments designed for college students, often leased by the bedroom near campuses. See Why Invest in Student Housing?

Assisted Living

Residential communities that provide housing plus help with daily activities for seniors. Operator quality matters a great deal. See Why Invest in Assisted Living?

Submarket

A specific neighborhood or area within a larger city, with its own supply, demand and rent trends.

Capitalization (Cap) Rate

NOI divided by property value. A property producing $500,000 in NOI that is valued at $8 million has a 6.25% cap rate. Cap rates are used to compare properties and estimate value.

Exit Cap Rate

The cap rate assumed when projecting the eventual sale price. Conservative sponsors assume it is the same as or higher than the purchase cap rate.

Exit Strategy

The plan for how and when the property will be sold or refinanced to return capital to investors.

Tax treatment is one of the biggest advantages of real estate. See The Biggest Tax Benefits of Real Estate Investing, and always confirm specifics with your own CPA.

Depreciation

A tax deduction that recognizes a building's wear over time. Residential rental buildings are generally depreciated over 27.5 years, which can reduce your taxable income.

Cost Segregation

A study that identifies parts of a property with shorter tax lives so more depreciation can be claimed sooner.

Bonus Depreciation

A provision that allows a larger share of certain asset costs to be deducted up front. The rules change, so check with a tax professional.

Schedule K-1

The tax form that reports your share of the partnership's income, losses and deductions. K-1s often arrive later than other tax forms, so plan ahead with your CPA.

Passive Activity Loss Rules

Tax rules that limit how passive losses can be used. In general, they offset passive income rather than wages, with some exceptions.

1031 Exchange

A strategy that defers capital gains tax by reinvesting sale proceeds into another like-kind property. You must identify the replacement property within 45 days and close within 180 days, and a qualified intermediary must hold the funds.

Accredited Investor

An individual who meets SEC criteria, generally income above $200,000 ($300,000 with a spouse or partner), or a net worth above $1 million excluding a primary residence, or who holds certain financial licenses. Many private offerings are limited to accredited investors.

Regulation D (Rule 506)

SEC exemptions that allow private companies to raise capital without a full public registration. Rule 506(c) allows general solicitation but requires the sponsor to verify that every investor is accredited.

Private Placement Memorandum (PPM)

The main disclosure document for a private offering. It explains the business plan, terms, fees, conflicts of interest and risks. Read the risk section carefully.

Subscription Agreement

The document you sign to commit your capital and confirm you are eligible to invest.

Letter of Intent (LOI)

A non-binding outline of key purchase terms sent before a formal contract.

Purchase and Sale Agreement (PSA)

The binding contract between the buyer and the seller.

Due Diligence

The period after a property goes under contract when the buyer inspects the property and verifies financials, leases and legal matters. As an investor, you should also do your own due diligence on the sponsor.

Acquisition Fee and Asset Management Fee

Common sponsor fees. The acquisition fee is a one-time payment for finding and closing the deal, and the asset management fee is an ongoing charge for overseeing the investment. Compare total fees across deals.
