Mortgage Basics

A mortgage is a loan that helps you buy a home. You pay it back a little at a time, usually every month. This guide explains how it works in simple terms.

What is a Mortgage?

A mortgage is money you borrow to buy a house. You agree to pay the lender back over many years. The house is the “collateral,” which means the lender can take the home if you stop paying. Think of it like this: A mortgage helps you buy a home now and pay for it slowly over time.

What Your Monthly Payment Includes

Most mortgage payments have four parts:

Principal

The money you borrowed.

Interest

The extra money the lender charges you for the loan.

 

Taxes

Money for your city or county. It goes into a special account.

 

Insurance

Homeowner’s insurance, and sometimes mortgage insurance.

 

These four parts are often called PITI. That just means: Principal, Interest, Taxes, Insurance.

Interest Rates (Made Simple)

Your interest rate is a number that affects how much your loan costs.

There are two main kinds:

Fixed-Rate

The rate stays the same the whole time. Your payment doesn’t change.

 

Adjustable-Rate (ARM)

The rate can go up or down after a few years. Your payment can change too.

 

 

A lower rate usually means a lower monthly payment.

Loan Lengths: 15-Year vs. 30-Year

Most people pick one of these:

30-year loan

Lower monthly payments, but you pay more interest overall.

 

15-year loan

Higher monthly payments, but you finish faster and save money.

 

Choose the one that fits your budget.

What Affects Your Interest Rate

Your interest rate is based on things like:

  • Your credit score

  • How much debt you have

  • Your income

  • How much you put down

  • The type of loan

  • The current economy

Better credit and less debt can help you get a lower rate.
