The multifamily underwriting glossary
35 terms defined the way an acquisitions team actually uses them: what the number means, how it is calculated, a worked example, and where it misleads. No filler definitions.
Returns
- Capitalization Rate (Cap Rate)
A capitalization rate is a property's net operating income divided by its purchase price, expressed as a percentage, and it represents the unlevered annual yield the property produces at that price.
- Cash-on-Cash Return
Cash-on-cash return is the annual pre-tax cash flow after debt service divided by the total equity invested, measuring the yearly cash yield an investor actually receives on their money.
- Equity Multiple
The equity multiple is total cash distributed to investors divided by total equity invested, expressed as a multiple, and it measures how many times an investor gets their money back over the full hold.
- Equity Waterfall
An equity waterfall is the contractual sequence of tiers that determines how a real estate deal's cash flow is split between limited partners and the general partner as return thresholds are met.
- Internal Rate of Return (IRR)
The internal rate of return is the annualized discount rate at which the present value of a deal's cash flows equals zero, making it the time-weighted compound annual return on invested equity.
- Preferred Return
A preferred return is a threshold rate of return that limited partners must receive on their invested capital before the general partner participates in profits above their pro rata share.
- Yield on Cost
Yield on cost is stabilized net operating income divided by total project cost including acquisition and capital expenditures, measuring the unlevered yield a business plan produces once complete.
Debt
- Bridge Loan
A bridge loan is short-term, usually floating-rate financing used to acquire and reposition a property that does not yet qualify for permanent debt, with the expectation of refinancing once the asset stabilizes.
- Debt Service Coverage Ratio (DSCR)
The debt service coverage ratio is net operating income divided by total annual debt service, and it measures how many times a property's income covers its loan payments.
- Debt Yield
Debt yield is net operating income divided by the total loan amount, measuring the unlevered return a lender would earn if it foreclosed and took the property back on day one.
- Interest-Only Period
An interest-only period is a stretch at the start of a loan term during which the borrower pays only accrued interest and no principal, lowering debt service and raising early cash flow.
- Loan-to-Value (LTV)
Loan-to-value is the loan amount divided by the appraised value or purchase price of a property, expressed as a percentage, and it measures how much of the capital stack is debt.
Income & expenses
- Capital Expenditures (CapEx)
Capital expenditures are investments in a property that extend its useful life, improve it, or reposition it, and they sit below the net operating income line rather than being treated as operating expenses.
- Economic Vacancy
Economic vacancy is the total percentage of gross potential rent not actually collected, including physical vacancy plus concessions, delinquency, non-revenue units, and loss to lease.
- Effective Gross Income (EGI)
Effective gross income is gross potential rent less vacancy, concessions, and credit loss, plus other income such as parking, pet fees, and utility reimbursements.
- Gross Potential Rent (GPR)
Gross potential rent is the total annual rent a property would collect if every unit were occupied at full market rent for the entire year, with no vacancy, concessions, or delinquency.
- Loss to Lease
Loss to lease is the difference between a property's market rent and the actual in-place rent on its current leases, representing income the property is contractually unable to collect until those leases roll.
- Mark to Market
Marking to market is the process of raising in-place rents to prevailing market levels as leases expire, converting loss to lease into collected income over the natural turnover cycle.
- Net Operating Income (NOI)
Net operating income is a property's effective gross income minus all operating expenses, excluding debt service, capital expenditures, depreciation, and income taxes.
- Operating Expense Ratio (OER)
The operating expense ratio is total operating expenses divided by effective gross income, expressed as a percentage, and it measures what share of collected revenue is consumed by running the property.
- Rent Roll
A rent roll is a unit-by-unit schedule of a property's leases showing unit type, square footage, current rent, market rent, lease start and expiration dates, and occupancy status.
- Replacement Reserves
Replacement reserves are an annual per-unit allowance set aside for the periodic replacement of major building components such as roofs, HVAC systems, and appliances, deducted as an operating expense by most lenders.
- Trailing Twelve (T12)
A trailing twelve is an operating statement showing a property's actual income and expenses for the most recent twelve months, and it is the primary evidence base for underwriting a multifamily acquisition.
Valuation
- Exit Cap Rate
The exit cap rate is the capitalization rate assumed to apply when a property is sold at the end of the hold period, and it converts projected final-year net operating income into an assumed sale price.
- Price Per Unit
Price per unit is a property's total purchase price divided by its number of units, and it is the standard shorthand for comparing multifamily pricing across deals in a market.
- Reversion Value
Reversion value is the projected gross sale price of a property at the end of the hold period, calculated by dividing the final year's net operating income by the assumed exit cap rate.
Market
- Absorption
Absorption is the net change in occupied units in a market over a period, measuring how quickly new and existing supply is being leased by tenants.
- Rent Comparables
Rent comparables are recently leased units at competing properties used to establish the market rent a subject property can achieve, adjusted for differences in size, condition, amenities, and location.
- Submarket
A submarket is a geographic subdivision of a metropolitan area that functions as a distinct competitive set, where properties compete directly with each other for the same pool of renters.
- Supply Pipeline
The supply pipeline is the volume of multifamily units permitted, under construction, or planned in a market, typically expressed as a percentage of existing inventory.
Process
- Due Diligence
Due diligence is the contractual period after a purchase agreement is signed during which a buyer inspects the property, audits its financials and leases, and can typically terminate and recover earnest money.
- Investment Committee Memo (IC Memo)
An investment committee memo is the written recommendation presented to a firm's decision-making body, summarizing a deal's thesis, underwriting, risks, and proposed terms in order to obtain approval to proceed.
- Letter of Intent (LOI)
A letter of intent is a short, generally non-binding document submitted by a prospective buyer that sets out the proposed price and principal terms of a transaction before a purchase agreement is drafted.
- Offering Memorandum (OM)
An offering memorandum is the marketing document a broker prepares to sell a commercial property, containing property details, financial statements, rent roll summaries, market data, and a proforma projection.
- Value-Add
Value-add is an investment strategy that acquires a property with identifiable operational or physical upside and invests capital to raise its net operating income, increasing value beyond market appreciation.
