Our Take

5.0

Home loans overall
NerdWallet rating
The Nerdy headline:
Alliant Credit Union allows you to see a wide range of customized mortgage rates without sharing any personal information, but beyond that the lender is a bit opaque. General information about its loan offerings is minimal and customer service is geared toward credit union members. Most likely to appeal to current Alliant members or borrowers already interested in credit union membership.

At a glance: Alliant mortgage options

Alliant Credit Union is a credit union based in Chicago. Mortgages are available in all states except Maryland, while its HELOC is only available in some states.
Alliant offers a pretty standard mix of mortgage types, though the information offered on their website is minimal.
🏠 Common mortgages • Fixed or adjustable rate • Conventional • FHA • VA • Jumbo • Rate-and-term refinance
🔑 Specialty loans • Construction loans • Physician loans
💵 Home equity • HELOC • Cash-out refinance

Alliant special offers and discounts

The Alliant Advantage mortgage lets buyers make a low down payment without having to pay for private mortgage insurance. First-time home buyers can put as little as 0% down, while repeat buyers need to make a 5% down payment.

What does Alliant specialize in?

A lender’s experience with your loan type can make a big difference. We looked at the latest federal data to find the types of mortgages Alliant handles most often.
Though most Alliant mortgages are conventional loans, the lender also does a significant number of jumbo loans.

How we score Alliant Credit Union’s home loans

Like to read the fine print? We do, too. Each year, NerdWallet writers and editors review the latest data and research on mortgage lenders, including federal data, and use a consistent method to score them based on what matters most to borrowers.
Alliant Credit Union earned a 5-star home loans overall rating from NerdWallet. Here’s how that score breaks down across our five weighted subcategories.
Excellent
  • Rates and fees (30%)

    Rates and fees determine how much a loan will cost you overall. NerdWallet reviews the latest federal data to score each lender’s average APR spread — a measure that combines interest rates and fees. A higher score means lower typical costs compared to other lenders.
Excellent
  • Product accessibility (20%)

    We evaluate how widely available a lender’s products are across the U.S. and how accessible they are to different financial profiles. A higher score means broader availability and more flexible requirements. A lower score means fewer options or stricter requirements.
Good
  • Customer experience (20%)

    We evaluate customer experience by testing and reviewing features like the online application, mobile app, and availability of phone or chat support. A higher score means a smoother, more convenient experience and easier access to help. A lower score means more friction or fewer support options.
Average
  • Loan variety (15%)

    We evaluate loan variety based on the range of home loan types a lender offers. A higher score means more options, while a lower score means a more limited selection.
Excellent
  • Rate transparency (15%)

    We review how clearly lenders share rate information on their websites, including sample rates and tools to estimate personalized rates. A higher score means it’s easy to find clear, comprehensive details and compare rates. A lower score means less information is available, often requiring you to contact the lender.

Nerdy Tip

NerdWallet’s ratings are objective and well-researched (we have the spreadsheets to prove it). But choosing a mortgage lender isn’t just about a star rating or a score breakdown. It’s also about finding the right lender for your unique situation. So yes: you can learn a lot from how the mortgage Nerds scored Alliant’s home loans. But you’re the expert when it comes to the features of your own best-match mortgage lender.

Alliant mortgage customer service options

Alliant Credit Union isn't super easy to get in touch with. There's an online chat, but you can't talk to an actual person. And while the lender does have a mobile app, it's strictly for regular banking tasks, like depositing checks. Here’s how you can get in touch with Alliant.

🤓 Our Nerds say... you'd better be a serious shopper

Face, Head, Person
Kate Wood, lead writer/lending spokesperson
Alliant is a tough lender to casually consider. The main phone number assumes you're a credit union member; when I called, I wound up stuck in a doom loop with a recording. I gave up after getting four versions of "I didn't understand that" when all I was saying was "yes." You can absolutely reach out to a loan officer directly — their full contact info, plus profiles that can give you an idea of their expertise, is readily available. But if you're just looking for basic info, talking to a loan officer might feel like too big of a step.

Alternatives to an Alliant Credit Union mortgage

Our biggest tip: Get offers from at least three different mortgage lenders. Comparison shopping can save you thousands of dollars. You can get rate quotes yourself, or work with a mortgage broker to shop around on your behalf.
If a credit union customer experience is what you're after, Andrews Federal Credit Union is another one that scored well in our research. If you're looking for specialty loan types, Flagstar Bank also offers physician loans and construction loans.

Methodology
NerdWallet rates mortgage lenders based on what matters most to borrowers: rates and fees, product accessibility, customer experience, rate transparency and the range of loan options.
We review more than 40 lenders and score them using a weighted system that prioritizes affordability and a smooth borrowing experience. Lenders earn higher scores for offering lower borrowing costs, making loans widely available, clearly displaying rate information and supporting borrowers from application through closing.
We use a mix of lender-provided information, publicly available data and our own research and analysis to evaluate each lender. Recent regulatory actions may affect a lender’s score.
