Mortgage

A loan secured by real property, where the lender can take the home if the borrower fails to repay. The property itself serves as collateral for the debt.

Related: Collateral, Default, Foreclosure
Collateral

An asset pledged to secure a loan. In residential lending, the home and land secure the mortgage, allowing the lender to recover funds if the borrower stops paying.

Related: Mortgage, Loan-to-Value Ratio, Foreclosure
Principal

The amount of money borrowed, separate from interest and fees. As payments are made, the outstanding principal balance declines, building the borrower's equity over time.

Related: Interest Rate, Amortization, Equity
Interest Rate

The percentage a lender charges on the outstanding loan balance, expressed annually. It determines the cost of borrowing and shapes the monthly payment amount.

Related: Principal, Amortization, Annual Percentage Rate
Amortization

The schedule by which a loan is paid down over time through regular payments split between principal and interest. Early payments are mostly interest; later payments are mostly principal.

Related: Principal, Interest Rate, Monthly Payment
Loan-to-Value Ratio (LTV)

The loan amount divided by the property's appraised value or purchase price, whichever is lower. Higher ratios signal greater lender risk and often trigger mortgage insurance requirements.

Related: Collateral, Private Mortgage Insurance, Appraisal
Combined Loan-to-Value Ratio (CLTV)

The total of all loans secured by the property divided by its value. It captures subordinate liens such as second mortgages or home equity lines that a first-lien LTV alone would miss.

Related: Loan-to-Value Ratio (LTV), Subordinate Lien, Home Equity Line of Credit
Down Payment

The portion of a purchase price the borrower pays from their own funds rather than financing. Larger down payments reduce LTV and lender risk.

Related: Loan-to-Value Ratio (LTV), Equity, Private Mortgage Insurance
Equity

The difference between a property's market value and the total debt secured by it. Equity grows through principal repayment and appreciation, and it protects lenders against loss.

Related: Down Payment, Loan-to-Value Ratio (LTV), Appraisal
Credit Score

A numerical summary of a borrower's credit history, commonly from FICO or VantageScore models. Underwriters use it to assess repayment likelihood and to set pricing and eligibility tiers.

Related: Credit Report, Debt-to-Income Ratio, Underwriting
Credit Report

A record from a credit bureau detailing a borrower's accounts, balances, payment history, inquiries, and public records. Underwriters review it to verify debts and spot derogatory items.

Related: Credit Score, Derogatory Item, Debt-to-Income Ratio
Derogatory Item

A negative entry on a credit report such as a late payment, collection account, charge-off, judgment, or bankruptcy. Underwriters weigh its recency, severity, and any explanation provided.

Debt-to-Income Ratio (DTI)

A borrower's total monthly debt obligations divided by gross monthly income. It measures capacity to repay and is central to loan approval and program eligibility.

Related: Housing Expense Ratio, Residual Income, Income Verification
Housing Expense Ratio

The share of gross monthly income consumed by housing costs, including principal, interest, taxes, insurance, and association dues. Often called the front-end ratio.

Related: Debt-to-Income Ratio (DTI), PITI, Residual Income
PITI

Principal, interest, property taxes, and hazard insurance, the four components of a typical monthly housing payment. Underwriters compare PITI plus other debts against income.

Related: Housing Expense Ratio, Escrow Account, Monthly Payment
Residual Income

The money left after subtracting housing costs, other debts, and estimated living expenses from take-home pay. Some programs use it instead of or alongside DTI to judge affordability.

Related: Debt-to-Income Ratio (DTI), Housing Expense Ratio, Income Verification
Income Verification

The process of documenting a borrower's earnings through pay stubs, tax returns, bank statements, or employer confirmation. It ensures the income used for qualification is stable and reliable.

Related: Debt-to-Income Ratio (DTI), Stable Income, Asset Verification
Stable Income

Earnings expected to continue at a similar level for the foreseeable future. Underwriters examine employment history, income type, and consistency to decide how much income can be counted.

Related: Income Verification, Variable Income, Self-Employed Borrower
Variable Income

Earnings that fluctuate, such as overtime, bonuses, commissions, or seasonal wages. Underwriters typically average it over a documented period and require a history of receipt.

Related: Stable Income, Income Verification, Self-Employed Borrower

Related: Variable Income, Income Verification, Cash Reserve
Asset Verification

The process of confirming a borrower's savings, investments, and other holdings used for down payment, closing costs, or reserves. Funds must be documented as sourced and seasoned.

Related: Cash Reserve, Down Payment, Gift Funds
Cash Reserve

Liquid funds remaining after closing that a borrower must show to cover future payments. Reserve requirements vary by program and rise with risk factors such as higher LTV.

Related: Asset Verification, Loan-to-Value Ratio (LTV), Liquid Asset
Liquid Asset

Cash or an investment that can be converted to cash quickly with little loss of value, such as a checking account or money market fund. Retirement accounts may count at a discount.

Related: Cash Reserve, Asset Verification, Gift Funds

Related: Comparable Sale, Loan-to-Value Ratio (LTV), Appraisal Waiver
Comparable Sale

Related: Appraisal, Market Value, Appraisal Waiver
Appraisal Waiver

A lender or automated system decision to accept a property's value without a full appraisal, usually based on data and risk models. It speeds processing but is not available for every loan.

Related: Appraisal, Automated Underwriting System, Loan-to-Value Ratio (LTV)
Market Value

The most probable price a property would bring in an open, competitive market under fair conditions. It is the reference point for LTV and for evaluating a purchase price.

Related: Appraisal, Comparable Sale, Loan-to-Value Ratio (LTV)
Title

The legal right of ownership in a property and the record of that ownership. Lenders require a clear title so the mortgage lien can be enforced without competing claims.

Related: Title Insurance, Lien, Title Search
Title Insurance

A policy protecting the lender, and optionally the owner, against losses from title defects such as undiscovered liens, fraud, or recording errors. It is typically purchased at closing.

Related: Title, Title Search, Lien

A legal claim against a property that secures a debt or obligation. A mortgage is a voluntary lien; tax liens and judgments are involuntary and can jeopardize the lender's position.

Related: Subordinate Lien, Title Search, Foreclosure

Related: Lien, Combined Loan-to-Value Ratio (CLTV), Foreclosure
Private Mortgage Insurance (PMI)

Related: Loan-to-Value Ratio (LTV), Escrow Account, Down Payment
Escrow Account

A lender-held account that collects portions of property taxes and insurance with each payment and disburses them when due. It protects the lender from unpaid tax or insurance bills.
