Financial Glossary
Plain-language explanations for all the financial terms used in the calculator. Understanding these concepts will help you make better decisions.
Amortization
MortgageThe process of spreading loan payments over time. Each payment covers interest and a portion of principal. Early payments are mostly interest; later payments are mostly principal.
ARM (Adjustable Rate Mortgage)
MortgageA mortgage with an interest rate that changes periodically based on a benchmark index. Typically starts with a lower fixed rate for 3-10 years, then adjusts annually.
Cap Rate (Capitalization Rate)
InvestmentNet Operating Income divided by property purchase price, expressed as a percentage. Measures the potential return on an investment property regardless of financing. Higher cap rates indicate higher potential returns but often higher risk.
Cash-on-Cash Return
InvestmentAnnual pre-tax cash flow divided by total cash invested. Unlike cap rate, this accounts for your financing structure. A 10% cash-on-cash return means you earn $10 annually for every $100 invested.
Cash to Close
PurchaseThe total amount of money you need to bring to the closing table. Includes down payment, closing costs, prepaids, escrow setup, minus any lender credits.
Closing Costs
PurchaseFees paid at closing beyond the down payment. Includes lender fees, title insurance, appraisal, attorney fees, recording fees, and more. Typically 2-5% of the purchase price.
Conventional Loan
MortgageA mortgage not backed by a government agency. Typically requires a higher credit score and larger down payment than government-backed loans. Conforming conventional loans follow Fannie Mae and Freddie Mac guidelines.
DSCR (Debt Service Coverage Ratio)
InvestmentNet Operating Income divided by annual debt service (mortgage payments). A DSCR above 1.0 means the property generates enough income to cover its debt. Lenders typically require 1.2 or higher for investment property loans.
DTI (Debt-to-Income Ratio)
FinanceTotal monthly debt payments divided by gross monthly income. Lenders use this to assess borrowing capacity. Generally, 36% or below is considered healthy; above 43% may make it difficult to qualify for a mortgage.
Down Payment
PurchaseThe upfront cash portion of the purchase price. For second homes, lenders typically require 10-25% down. Investment properties often require 20-30% down.
Effective Gross Income
InvestmentGross potential rental income adjusted for expected vacancy and occupancy rate. Represents the realistic income you can expect from a rental property.
Emergency Fund
FinanceCash reserves set aside for unexpected expenses. Financial advisors typically recommend 3-6 months of total expenses. With multiple properties, 6-12 months is often recommended.
Escrow
MortgageAn account held by the lender to collect monthly portions of property taxes and insurance. At closing, you may need to fund several months of escrow in advance (prepaids).
HELOC (Home Equity Line of Credit)
FinanceA revolving credit line secured by your home equity. Can be used as a funding source for a second property purchase but adds variable-rate debt to your primary home.
HOA (Homeowners Association) Fees
CostsMonthly or annual fees paid to a homeowners association for maintenance of common areas, amenities, and sometimes exterior maintenance. Varies widely by property and location.
Homestead Exemption
TaxA tax break that reduces the assessed value of your primary residence for property tax purposes. Not available for second homes or investment properties in most states.
Interest-Only Mortgage
MortgageA loan where you only pay interest for a set period (typically 5-10 years). After the interest-only period, payments increase significantly as you begin paying principal.
Jumbo Loan
MortgageA mortgage that exceeds the conforming loan limits set by the FHFA. Typically requires stronger credit, lower DTI, and larger down payment. Rates may be slightly higher.
Liquidity
FinanceHow quickly and easily an asset can be converted to cash. Cash savings are highly liquid; real estate is illiquid. Buying property reduces your overall liquidity.
Mortgage Insurance (PMI)
MortgageInsurance that protects the lender if you default. Required on conventional loans with less than 20% down payment. Can be removed once you reach 20% equity.
Net Operating Income (NOI)
InvestmentTotal rental income minus all operating expenses (excluding mortgage payments). Used to calculate cap rate and DSCR. Includes taxes, insurance, management, maintenance, and vacancy.
Opportunity Cost
FinanceThe potential return you give up by choosing one investment over another. For example, using brokerage funds for a down payment means forgoing the market returns those funds would have earned.
Points (Discount Points)
MortgageUpfront fees paid to the lender to reduce your interest rate. One point equals 1% of the loan amount and typically reduces the rate by 0.25%. Worth it if you plan to keep the loan long enough to recoup the cost.
Prepaids
PurchaseExpenses paid in advance at closing. Typically includes prepaid interest (from closing date to month end), initial escrow deposits for property taxes and insurance.
Property Tax
TaxAnnual tax assessed by local government based on property value. Rates vary significantly by state and locality, from under 0.5% to over 2.5% of assessed value.
Transfer Tax
TaxA tax charged when property ownership changes hands. Rates and who pays (buyer vs seller) vary by state and locality. Some states have no transfer tax.
Vacancy Reserve
InvestmentMoney set aside to cover periods when a rental property is unoccupied. Typically 5-10% of gross rent for long-term rentals, higher for short-term or vacation rentals.
