Full Review

If you like the personalized service that comes with a smaller mortgage lender but want the high-tech tools to manage your loan on your terms, an Alliant Credit Union mortgage might fit the bill.

The not-for-profit financial cooperative, in which the members are also owners, is investing heavily in online and mobile technology as a “digital credit union.”

Founded in 1935, Alliant says it now has more than 450,000 members nationwide and manages more than $11 billion in assets, making it one of the largest credit unions in the country.

Alliant Credit Union mortgage products

In addition to offering a full array of fixed- and adjustable-rate loans, Alliant offers Freddie Mac's Home Possible program and Fannie Mae's HomeReady program. Both provide first-time home buyers with loan options that require as little as 3% down. With the Alliant Advantage Mortgage program, qualified first-time home buyers can get a mortgage with 0% down payment and no private mortgage insurance.

Loans are available for non-warrantable condos as well. These extra offerings help expand homeownership opportunities to more of its members.

"Today’s borrower doesn’t have a deep well of assets for a down payment,” says Jason Osterhage, senior vice president of lending at Alliant. “We are a portfolio lender [offering our own products], and that gives us some flexibility to update our guidelines, look at loan performance, and find ways to adjust.”

The credit union is exploring alternative credit scoring models that are responsive to fair lending considerations, Osterhage says. While the credit union isn’t planning to be on the leading edge of those efforts, it wants to do what's best for customers and get underwriting guidelines right through careful research, he adds.

Alliant also offers refinance loans and home equity lines of credit in most states, as well as lender-paid mortgage insurance, which pays for premiums on loans with less than 20% down.

Alliant Credit Union digital mortgage experience

Alliant has only one public branch where you can go in person to apply for a mortgage, located at its Chicago headquarters. The bulk of its mortgage business is done online, which sets it apart from other credit unions, Osterhage says.

At Alliant, online doesn’t mean anonymous. If you take out a mortgage with the lender, you’ll work with a dedicated loan officer throughout the process.

One way Alliant differentiates itself among credit unions, which are not known for being tech-focused, is by investing in a comprehensive suite of online tools for its members.

Alliant launched a mobile app in 2016, though it provides only standard mobile banking functionality. But the lender says its online application is optimized for use on mobile devices.

If you are eligible to join Alliant through a qualifying employer or organization, it offers the personalized service and competitive mortgage rates of a credit union, with the technology you’d expect from a major bank. An Alliant Credit Union mortgage is a solid, smart choice for your mortgage needs if you are comfortable with online banking and aren’t married to the idea of going into a local branch to talk to a loan officer.
