Key Facts

Understanding Mortgages

A mortgage is a financial arrangement where a borrower receives funds from a lender to purchase real estate, using the property as collateral. The borrower commits to repaying the loan with interest over a predetermined period, typically 15 to 30 years. This arrangement makes homeownership accessible to people who cannot pay the full property price upfront.

How Mortgages Work

The process begins when a borrower applies for a mortgage, providing financial information and undergoing credit evaluation. The lender assesses the property's value and the borrower's ability to repay. If approved, the borrower receives funds at closing, and the property deed is recorded with the lender holding a mortgage lien. The borrower then makes regular monthly payments.

Types of Mortgages

Fixed-rate mortgages maintain the same interest rate throughout the loan period, providing payment predictability. Adjustable-rate mortgages (ARMs) start with lower rates that adjust periodically, introducing payment variability. Other options include FHA loans with government backing, VA loans for veterans, and conventional mortgages for qualified borrowers. Each type serves different borrower needs and financial situations.

Monthly Payments and Costs

Monthly mortgage payments typically include principal repayment, interest charges, property taxes, homeowners insurance, and potentially private mortgage insurance (PMI). The PITI acronym represents these four main components. Early payments are predominantly interest, while later payments gradually shift toward principal repayment as the loan balance decreases.

Foreclosure and Default

If a borrower fails to make required payments, the lender can initiate foreclosure proceedings, seizing the property to recover the outstanding loan balance. This process protects the lender's investment but has severe consequences for the borrower, including credit damage and potential homelessness. Default is therefore a serious matter with long-lasting financial implications.

What's the difference between fixed and adjustable rate mortgages?

Fixed-rate mortgages maintain constant interest rates and predictable payments throughout the loan term. Adjustable-rate mortgages start with lower rates that increase over time, offering initial savings but future payment uncertainty.

How much house can I afford?

What's an amortization schedule?

An amortization schedule is a detailed table showing each mortgage payment's breakdown between principal and interest. It demonstrates how the loan balance decreases over time with regular payments until the debt is fully repaid.
