Real Estate Terms, Plainly Defined

Short, precise definitions of the terms investors and landlords actually use — the math, the paperwork, and the process words — with the related concepts linked so one lookup answers the next question too.

1031 Exchange

A transaction under Section 1031 of the U.S. Internal Revenue Code that lets an investor defer capital gains tax by selling an investment property and reinvesting the proceeds in another like-kind investment property. The rules are strict: replacement property must generally be identified within 45 days of the sale and acquired within 180 days, with the funds held by a qualified intermediary in between. The tax is deferred, not eliminated — it carries into the new property’s basis.

Amortization

The gradual repayment of a loan through scheduled payments that cover both interest and principal. Early payments are mostly interest; the mix shifts toward principal as the balance falls. An amortization schedule shows how each payment splits and what remains owed at any point in the loan’s life.

Appreciation

An increase in a property’s market value over time, whether from market conditions, inflation, or improvements the owner makes (often called forced appreciation). Unlike cash flow, appreciation is unrealized until the property is sold or refinanced. Values can also fall — appreciation is a possibility, not a guarantee.

BRRRR

Buy, Rehab, Rent, Refinance, Repeat — a strategy where an investor buys a property below market value, renovates it, places a tenant, then refinances against the new appraised value to recover much of the invested cash before repeating the cycle. The refinance step depends on the post-rehab appraisal and current lending terms, which is where the strategy carries most of its risk.

CapEx (Capital Expenditures)

Spending on major components that extend a property’s life or add value — roofs, HVAC systems, water heaters, full renovations — as opposed to routine repairs and upkeep. Investors typically budget a recurring reserve for capex even in years when nothing is replaced. Most analyses treat capex separately from operating expenses, so it sits below NOI.

Cash Flow

The money left over after all of a property’s bills are paid from its income — operating expenses, loan payments, and reserves. Positive cash flow means the property pays for itself with margin; negative cash flow means the owner feeds it. Cash flow is the recurring return, distinct from appreciation and tax effects.

Cash-on-Cash Return

Annual pre-tax cash flow divided by the total cash actually invested — down payment, closing costs, and upfront repairs — expressed as a percentage. Unlike cap rate, cash-on-cash accounts for financing, so it shows what the investor’s own money is earning. Two identical properties can have very different cash-on-cash returns depending on the loan.

Depreciation (Tax)

A federal tax deduction that lets owners of income-producing property recover the cost of buildings and improvements — not land — over a set recovery period. U.S. rules currently assign residential rental buildings a 27.5-year period. Depreciation reduces taxable income without a cash outlay, and prior deductions may be subject to recapture when the property is sold.

Due Diligence

The investigation a buyer performs before completing a purchase: inspections, title review, verifying leases and income, checking taxes, insurance costs, and anything else that could change the deal’s math. Purchase contracts often include a due-diligence or inspection period during which the buyer can renegotiate or exit under the contract’s terms.

Earnest Money

A deposit the buyer puts down when an offer is accepted to show serious intent, typically held by a neutral party such as an escrow or title company. At closing it is credited toward the purchase. Whether it is refundable if the deal falls apart depends on the contract’s contingencies.

Escrow

An arrangement where a neutral third party holds money or documents until agreed conditions are met — for example, holding a buyer’s deposit until closing. The word also describes lender-managed accounts that collect property taxes and insurance alongside the mortgage payment and pay those bills when due.

Eviction

The legal process by which a landlord regains possession of a rental unit, generally involving a formal written notice, a court filing, a hearing, and — if the landlord prevails — a court order enforced by an authorized official. Landlords cannot lawfully remove tenants themselves by changing locks or shutting off utilities. Notice periods, grounds, and timelines are set by state and local law and vary by jurisdiction.

Fair Housing

The body of law, anchored by the U.S. Fair Housing Act of 1968, that prohibits discrimination in the sale, rental, financing, and advertising of housing based on race, color, religion, sex, national origin, familial status, and disability. Many states and cities extend protection to additional classes. It applies across the rental process — advertising, screening, terms, and treatment during a tenancy.

Gross Rent Multiplier

A property’s price divided by its gross annual rental income. GRM is a quick first-pass screen — a lower multiple means the price is smaller relative to the rent it produces. Because it ignores expenses entirely, it is cruder than cap rate and best used only to shortlist properties for real analysis.

Hard Money Loan

A short-term loan from a private lending company, secured by the property and underwritten mainly on the asset’s value — often its ARV — rather than the borrower’s income. Rates and fees run well above conventional mortgages, but closings are fast and condition requirements are loose, which is why flippers and BRRRR investors use them as bridge financing.

House Hacking

Living in one part of a property while renting out the rest — the other units of a small multifamily, a basement apartment, or spare bedrooms — so rental income offsets the cost of housing. Because the owner lives there, the purchase can often be made with owner-occupant financing, which typically carries lower down payments than investor loans.

Lease Abstract

A condensed summary of a lease’s key terms: the parties, unit, rent, start and end dates, deposits, renewal options, and who is responsible for what. Abstracts let an owner, buyer, or lender review the essentials of many leases without rereading every full document. They summarize the lease but do not replace it — the lease itself governs.

Operating Expenses

The recurring costs of running a property: property taxes, insurance, management, routine maintenance, utilities the owner pays, and similar line items. Operating expenses exclude mortgage payments and capital expenditures. Subtracting them from income yields NOI, so what counts as an operating expense directly shapes every metric built on it.

Private Money

Loans from individuals — often people the borrower knows, or investors seeking yield — rather than from banks or hard money lending companies. Terms, rates, and security are whatever the two parties negotiate, which makes private money more flexible and more relationship-dependent than institutional lending.

Rent Roll

A document listing every unit in a property or portfolio along with its tenant, rent, lease dates, and payment status — a one-page snapshot of the income side of the operation. Lenders and buyers ask for the rent roll early because it shows, unit by unit, where the income actually comes from and how current it is.

Security Deposit

Money a tenant pays at move-in that the landlord holds as security against unpaid rent or damage beyond normal wear and tear. State and local laws commonly set limits on the amount, rules for how deposits are held, and deadlines for returning them with an itemized statement after move-out.

Seller Financing

A sale in which the seller acts as the lender: the buyer takes ownership and pays the seller in installments under negotiated terms instead of — or alongside — a bank loan. It can open deals that conventional financing would not reach, and the terms are set by the contract the parties sign.

Vacancy Rate

The share of units or time a rental sits empty and producing no income, expressed as a percentage. A single unit vacant one month out of twelve has an 8.3% vacancy rate for the year. Investors underwrite an assumed vacancy rate so that one bad month does not surprise the whole year’s numbers.

Wholesaling

Putting a property under contract and then assigning that contract to another buyer for a fee before closing, so the wholesaler profits on the spread without ever taking title. The model depends on finding deals below market value and having buyers ready. Rules on marketing properties under contract and on licensing vary by jurisdiction.
