What to Compare When You Are Shopping for a Mortgage

A mortgage is a loan secured by the house itself — if you stop paying, the lender can take the property. When you shop for one, you are comparing four main things: the interest rate (the percentage you pay yearly), the loan term (how many years to repay), the type of rate (fixed or adjustable), and the fees the lender charges upfront. The interest rate matters most because it determines your monthly payment and total cost over the life of the loan. A difference of even 0.5% between lenders can mean tens of thousands of dollars.

You will also encounter the term APR, which stands for annual percentage rate. The APR includes the interest rate plus certain fees, so it is a more complete picture of what the loan actually costs you per year. Lenders are required to show you the APR so you can compare apples to apples across different offers.

Key Takeaways

  • Interest rates vary between lenders and change daily, so getting quotes from at least three lenders lets you see the real range available to you.
  • A fixed-rate mortgage keeps the same interest rate for the entire loan term, while an adjustable-rate mortgage starts lower but can increase after a set period.
  • The loan term (15, 20, or 30 years) affects both your monthly payment and the total amount you pay — shorter terms cost less overall but have higher monthly payments.
  • Upfront fees include origination fees, appraisal costs, and title insurance, and these vary widely between lenders, so ask for a complete fee list before committing.
  • Your credit score, down payment size, and debt-to-income ratio determine which rates and terms each lender will offer you.

Fixed-Rate Versus Adjustable-Rate Mortgages

A fixed-rate mortgage locks in one interest rate for the entire loan — 15 years, 30 years, or whatever term you choose. Your monthly payment never changes. This makes budgeting predictable and protects you if interest rates rise. Most first-time buyers choose fixed-rate mortgages because the payment is stable.

An adjustable-rate mortgage (ARM) starts with a lower interest rate for a set period — often 3, 5, 7, or 10 years — then adjusts annually or every few years based on market rates. After the initial period ends, your payment can jump significantly. ARMs are riskier because you cannot predict what you will owe later. They make sense only if you plan to sell or refinance before the rate adjusts, or if you are confident your income will rise enough to handle a higher payment.

Compare the starting rate on an ARM to the fixed rate on a conventional loan. The ARM might be 0.5% lower initially, but once it adjusts, it could end up higher than the fixed rate you turned down. Ask the lender for the worst-case scenario — what is the highest the rate could go, and when?

Loan Terms and Monthly Payments

The most common loan terms are 15, 20, and 30 years. A shorter term means a higher monthly payment but much less interest paid overall. A 30-year mortgage spreads payments over more months, so each payment is smaller, but you pay significantly more in total interest.

For example, on a $300,000 loan at 6.5% interest, a 30-year term might have a monthly payment around $1,896, while a 15-year term might be around $2,899 per month. Over the life of the loan, the 30-year borrower pays roughly $180,000 more in interest. However, the 30-year borrower has $1,000 more per month in cash flow for other expenses or savings.

Choose based on your budget and goals. If you can afford the higher payment and want to build equity faster and pay less interest, a 15-year term works. If you want lower monthly payments and more financial flexibility, a 30-year term is more realistic for most households. Some lenders also offer 20-year terms as a middle ground.

Understanding Fees and Closing Costs

Lenders charge several upfront fees, collectively called closing costs. These typically include an origination fee (1% to 1.5% of the loan amount), an appraisal fee (usually $300 to $500), title insurance, credit report fees, and underwriting fees. Closing costs often total 2% to 5% of the loan amount, though this varies by lender and location.

Some lenders advertise "no closing cost" mortgages, but this is misleading — the costs do not disappear, they are rolled into the interest rate, meaning you pay them over time with interest. Compare the total cost, not just the upfront cost. Ask each lender for a Loan Estimate form, which shows all fees side by side. This document is required by law and must be provided within three business days of your process.

Watch for junk fees — charges with vague names like "processing fee" or "underwriting fee" that some lenders pad. Ask what each fee covers and whether it is negotiable. Some fees, like appraisal and title insurance, are harder to negotiate, but origination fees and discount points often are.

How Your Credit Score and Down Payment Affect Your Offer

Lenders use your credit score to decide what interest rate to offer you. A higher credit score gets a lower rate; a lower score gets a higher rate. The difference can be substantial — a borrower with a 760 score might get 6.0%, while a borrower with a 620 score might get 7.5% on the same loan. Over 30 years, that 1.5% difference costs tens of thousands of dollars.

Your down payment also affects the rate. A larger down payment (20% or more) signals lower risk to the lender and often qualifies you for better rates. A smaller down payment (3% to 10%) may may have access to you for a loan, but the lender will charge a higher rate and require mortgage insurance — an extra monthly fee that protects the lender if you default. Mortgage insurance typically costs 0.5% to 1% of the loan amount per year.

Before you shop for mortgages, check your credit report for errors and pay down high-balance credit cards if possible. Even a small improvement in your credit score can lower your interest rate. If your down payment is less than 20%, ask lenders whether the mortgage insurance is required for the entire loan term or just until you reach 20% equity.

Getting Quotes and Comparing Offers

Contact at least three lenders — a bank, a credit union, and a mortgage broker — and ask for a rate quote. Rates change daily, so get quotes on the same day for a fair comparison. Tell each lender the same loan amount, down payment, and loan term so the quotes are comparable. Each lender will ask for basic financial information: income, employment history, assets, and debts.

When you receive quotes, compare the interest rate, the APR, and the total closing costs. The APR is more useful than the rate alone because it includes fees. A lender with a slightly higher rate but much lower fees might cost you less overall. Use an online mortgage calculator to estimate your monthly payment under each scenario — small differences in rate add up over time.

Once you have narrowed it down to one or two lenders, ask whether they will match or beat a competitor's offer. Some will, especially on the origination fee or discount points. Do not lock in your rate until you are ready to move forward — rate locks typically last 30 to 60 days, and if rates drop, you want to be able to take advantage.

Pre-Approval Versus Pre-Qualification

A pre-qualification is informal — the lender estimates what you might borrow based on information you provide, but does not verify anything. It is useful for getting a rough idea of your budget, but it is not a commitment from the lender.

A pre-approval is formal. The lender verifies your income, credit, and assets and issues a written commitment to lend you up to a certain amount at a certain rate (for a set period, usually 30 to 60 days). Pre-approval shows sellers you are a serious buyer and have already been vetted by a lender. Most real estate agents will not show you homes until you have a pre-approval letter.

Get pre-approved before you start house hunting. It clarifies your actual budget and strengthens your offer when you find a home. Pre-approval does not lock you into that lender — you can still shop around and switch lenders before closing, though you will need to get re-approved if too much time passes.

Common Mistakes to Avoid

Do not assume the first lender you contact has the best rate. Shopping around takes a few hours but can save you thousands. Do not explore with multiple lenders in a short window just to compare — multiple hard inquiries on your credit report can temporarily lower your score. Instead, gather quotes within a two-week window; credit bureaus treat multiple mortgage inquiries in a short period as a single inquiry.

Do not change jobs or take on new debt between pre-approval and closing. Lenders verify employment and credit again before funding the loan, and changes can delay closing or disqualify you. Do not max out your down payment if it leaves you with no emergency savings — you will need cash for repairs, inspections, and moving costs.

Do not focus only on the monthly payment. The interest rate and total cost matter more. A lender offering a 0.25% lower rate saves you money even if the monthly payment looks similar. Do not skip the fine print on the Loan Estimate — read the terms, the rate lock details, and the list of fees carefully before signing.

Frequently Asked Questions

What is the difference between a mortgage broker and a bank?

A bank lends its own money and has one set of loan products. A mortgage broker works with multiple lenders and can shop your process around to find the best fit. Brokers are useful if you have an unusual financial situation, but they charge a fee (usually paid by the lender, not you). Banks may have lower fees but less flexibility.

Can I get a mortgage with a lower credit score?

Yes, but the interest rate will be higher. Most lenders require a minimum score of 580 to 620 for conventional loans. FHA loans, backed by the federal government, accept scores as low as 500 but require mortgage insurance. If your score is very low, consider waiting a few months to pay down debt and improve it before explore.

What does it mean to lock in a rate?

A rate lock freezes your interest rate for a set period, usually 30 to 60 days. If rates rise during that time, your rate stays the same. If rates fall, you cannot take advantage unless you negotiate a float-down clause. Rate locks protect you but also commit you to moving forward — if you back out, you may lose the lock.

Should I pay points to lower my interest rate?

Points are upfront fees (each point costs 1% of the loan amount) that lower your interest rate. They make sense if you plan to stay in the home long enough to recoup the cost through lower monthly payments. Use a calculator to find your break-even point — if you plan to move or refinance before then, skip the points.

What happens if I cannot get a mortgage from a traditional lender?

Explore FHA loans (require 3.5% down and accept lower credit scores), VA loans (if you are military), USDA loans (if you are buying in a rural area), or portfolio lenders who hold loans in-house and have more flexible standards. Each has different requirements and costs, so compare them to conventional mortgages.
