Whether you’re looking for more space for a growing family, a shorter commute, a new neighborhood, or simply daydreaming about the perfect porch for your morning coffee, a mortgage is a key part of turning your homeownership goals into reality. Whatever is inspiring your next move, before you start house hunting, it’s important to understand know what your mortgage options are.

Keep reading for tips on shopping for a mortgage, from easy ways to help determine how much you can afford to what extra fees to look out for. You'll also discover how Alliant's Journey Home program can help you finance, find a home, and move in, while earning up to $9,000 back at closing.*

What you’ll learn

Determine how much house you can afford

Before comparing mortgage lenders, calculate how much home you can comfortably afford so you can request accurate mortgage quotes.

You’ll need to put together some basic but pertinent information to make it easier to get mortgage quotes. First, figure out the estimated home price range you can afford—use a simple mortgage calculator to help you—and your estimated down payment amount. Note that lenders typically price their mortgage loan programs based on your down payment percentage (0%, 3%, 5%, 10%, and 20% or above), not the actual dollar amount.

Establish your homebuying timeline

Next, determine an estimated timeframe when you plan to purchase your new home, the property type you’re interested in, such as a single-family home or condo, and whether you’ll be using the property as your primary residence, a vacation home, or an investment property.

If you’re aiming to be in your next home for a new school year or a desired season, set a realistic timeline. Most U.S. homebuyers spend about two to three months searching for a home, then another one to two months completing the mortgage and closing process. In competitive markets with limited inventory, the search portion can take several months longer.

Compare mortgage quotes from multiple lenders

A good rule of thumb is to compare at least three mortgage lenders, plus your current bank or credit union if they offer home loans.

When requesting a quote, some lenders may perform a hard credit inquiry, which could negatively impact your credit score. However, some lenders, like Alliant Credit Union, have tools on their website so that you can estimate your mortgage payment before formally applying and having your credit pulled. When that is the case, there is no harm in getting multiple quotes, comparing them, and then requesting an official quote from a lender or two.

Consider different mortgage loan types

The best mortgage is not always the one with the lowest advertised rate. Different loan types have different down payment requirements, qualification standards, and long-term costs.

Each lender should give you multiple options to consider. Typically, a lender will show you their 30-year fixed mortgage rate, which tends to be the more popular option. But, if the loan officer has asked you questions and gathered information based on your specific situation, they should also be able to give you one or two alternatives to consider. For instance, they might give you an option between a 10-year adjustable rate and 30-year fixed rate. If they don’t give you these options right from the beginning, don’t be afraid to ask.

Types of mortgages a lender could provide include:

  • Conventional. A conventional mortgage is a traditional option, with no special eligibility requirements or criteria needed to qualify beyond proof of income, a strong credit score, a good debt-to-income ratio, etc. Private lenders, such as banks and credit unions, back these mortgages. While this is the standard option, the lending criteria is stricter than other options geared to assist specific groups of people, such as veterans, doctors, or low-income individuals. Additionally, while conventional mortgages often only require a 3% down payment, you can expect to pay private mortgage insurance (PMI) for down payments under 20%.
  • FHA. Federal Housing Administration (FHA) loans are government-backed loans that allow for significantly lower down payments than a conventional mortgage. Compared to a traditional down payment of 20%, an FHA loan only requires a 3.5% down payment, provided you meet the credit score requirements. This makes FHA loans a great option for first-time homebuyers that might otherwise struggle to save up a full 20% down payment.
  • VA. Veterans Administration loans are available to qualified veterans, active-duty military personnel, and some surviving spouses. These mortgages are backed by the U.S. government and thus have lower risk for financial institutions. VA mortgages often have no down payment requirement, don’t require PMI, and have lower rates than conventional mortgages.
  • Jumbo. Jumbo mortgages are like conventional mortgages, but for large loan amounts that exceed the local conventional maximum. This number shifts upwards over time due to inflation. In 2025, this amount is $806,500 in most counties but could be as high as $1,209,750, depending on where you’re looking to buy. These loans are riskier for lenders but work similarly for the consumer taking on the loan. The main differences are that jumbo loans often require a larger down payment (typically at least 10%), a high credit score, and more extensive documentation proving your ability to pay the loan.

Compare lender fees, requirements, and service

Ask lenders about any fees they charge and estimated third-party costs, like appraisal or legal fees. Some lenders may charge one flat fee for loan originations for all of its mortgage products, but others may break their fees into categories like origination, underwriting, and processing.

If you are putting down less than 20% for a down payment, ask the lender if they require you to have private mortgage insurance (PMI) or to escrow funds for property taxes and home insurance into your monthly payments.

Another consideration is the lender’s process. You want to make sure you close on time once you go under contract, so if the lender can’t lay out a streamlined process to help ensure it happens, that could lead to major headaches down the road.

Factor Why It Matters
Interest Rate Affects monthly payment
APR Reflects total borrowing cost
Closing Costs Impacts upfront expense
PMI Requirements Increases monthly cost
Customer Service Affects loan experience
Closing Timeline Important in competitive markets

Frequently asked questions about shopping for a mortgage

How many mortgage lenders should I compare?

Most experts recommend comparing at least three mortgage lenders to evaluate rates, fees, loan terms, and customer service options.

Does shopping for a mortgage hurt your credit score?

Multiple mortgage inquiries made within a short shopping window, typically 14 to 45 days, are generally treated as a single inquiry for credit-scoring purposes.

What should I look for in a mortgage lender?

Look for a lender that offers competitive rates, transparent fees, the right loan options for your needs, strong customer service, and a reliable closing timeline. It’s also important to compare APR, PMI requirements, and total cash needed at closing.

What credit score do you need for a mortgage?

Minimum requirements vary by lender and loan type, but higher credit scores generally qualify for better mortgage rates. Learn more about credit scores and mortgage rates. 

What is the best way to compare mortgage lenders?

Compare APR, interest rates, closing costs, lender fees, customer reviews, and available loan programs.

How long does mortgage shopping take?

Many borrowers can compare quotes within a few days and complete underwriting in several weeks.

Is the lowest mortgage rate always the best deal?

Not always. A lower rate can still come with higher lender fees, mortgage insurance costs, or less favorable loan terms. Comparing APR and total closing costs can give you a more complete picture.
