Mortgage & Home Loans

What is Mortgage?

A mortgage is a loan used to buy or maintain real estate. You agree to make regular payments—typically over 15 or 30 years—split between paying down the principal and covering interest. The property serves as collateral: if you stop paying, the lender can foreclose and sell it to recover what you owe.

Under CFPB rules, lenders must verify your ability to repay using documented income, assets, and liabilities before approving a mortgage. Once signed, the mortgage is recorded as a lien on the property title.

Choosing a mortgage means comparing rates, terms, and types like fixed or adjustable. Over 30 years, the total interest often exceeds the original purchase price—so understanding amortization matters for building wealth.

PRACTICAL EXAMPLE

Say you buy a $400,000 home with 20% down ($80,000) and finance the remaining $320,000 at 6.5% for 30 years. Your monthly payment comes to $2,022.62. Over the full term, you'll pay $728,143.20—more than half of that in interest alone.
