How to Structure Your Mortgage Deal
Understand your payment, compare loan options, and leave room for the life you want.
Your mortgage should fit more than the home you want. It should fit the life you want to live in it. Understanding your payment, loan term, and borrowing costs can help you compare options and keep room in your budget for what comes next.

What’s PITI?
PITI stands for principal, interest, taxes, and insurance. It’s a useful starting point for understanding your housing payment, but your budget may also need to cover mortgage insurance, HOA dues, utilities, and maintenance.
Principal
Principal is the amount you borrow before interest. If you buy a home for $300,000 with a 20% down payment of $60,000, your loan principal is $240,000.
Lenders also consider your debt-to-income ratio: your monthly debt payments divided by your gross monthly income. Requirements vary by lender and loan program. Your own budget should also leave room for everyday expenses, savings, and unexpected costs.
Interest
Interest is the cost of borrowing money. Your rate, loan balance, and repayment term all affect how much you pay.
Early in a standard amortizing mortgage, more of each payment goes toward interest because your outstanding balance is larger. As that balance falls, more of the payment goes toward principal.
Taxes
Property taxes depend on the home’s location and assessed value. Check local estimates and whether the assessment may change after purchase.
Budget separately for closing costs, using your Loan Estimate to understand the charges and cash needed to close.
Insurance
Homeowners insurance protects your property; mortgage insurance protects the lender. Conventional loans commonly require PMI with less than 20% down. Other loan programs have different requirements.
Compare the actual insurance costs shown in your loan estimates.

A percentage point can make a meaningful difference.
On a $300,000, 30-year mortgage, reducing the rate from 7% to 6% lowers the principal-and-interest payment by about $197 a month and total interest by about $71,012 over the full term. Compare any additional fees or points alongside those savings.
- Monthly principal and interest
- $1,995.91
- Total interest over 30 years
- $418,526.69
- Monthly principal and interest
- $1,798.65
- Total interest over 30 years
- $347,514.57
About $197 more room each month. Consider the upfront costs as well as the monthly savings.

At 7%, the first month’s interest on a $300,000 loan is $1,750. The remaining approximately $245.91 of the principal-and-interest payment reduces the loan balance.
A lower rate generally reduces interest when the loan amount and term are the same. But the rate alone doesn’t tell the whole story. Compare fees, points, the loan term, and how long you expect to keep the mortgage.

Why Worry About PITI?
Use PITI to understand the housing payment, then look beyond it. A payment that meets a lender’s requirements still needs to work with your household budget and goals.
Your home is part of your financial picture. Leave room for the expenses, savings, and everyday choices that make your budget work.
Adjustable vs. Fixed-Rate Mortgages
Fixed rate
A fixed-rate mortgage keeps the same interest rate and principal-and-interest payment throughout the term, although taxes and insurance can change.
Adjustable rate
An ARM may offer a lower introductory rate, then adjust under the loan’s index, margin, and caps. Compare potential future payments as well as the starting payment.
Balance the payment and the long-term cost
Your Mortgage Term
A shorter term generally means higher required payments and less total interest. A longer term generally lowers the required payment but increases total interest. Consider both the cost and the breathing room your budget needs.
15 years: a shorter repayment path
A $300,000 fixed-rate mortgage at 6.5% over 15 years has a principal-and-interest payment of $2,613.32 a month and approximately $170,397.98 in total interest.
The higher required payment needs to fit comfortably alongside your other expenses and goals.
30 years: a lower required payment
A $300,000 fixed-rate mortgage at 7% over 30 years has a principal-and-interest payment of $1,995.91 a month and approximately $418,526.69 in total interest.
The lower required payment leaves more monthly flexibility, but borrowing over a longer period generally costs more.
