A few more details worth knowing

Though these don't affect the star rating, we show them so you have the full picture.

AverageOlder borrower outcomes

For applicants age 62 and older, we measure two things: whether this lender denies them more often than its own lending patterns would predict after accounting for loan size, income, debt-to-income ratio, and loan type; and whether it lends to them at rates similar to comparable lenders. Importantly, federal mortgage disclosure data does not include applicants' credit scores, so the analysis cannot account for differences in creditworthiness that may explain some disparities. This limitation applies to all lenders, making comparisons more consistent, but its impact may vary across lenders. These measures identify potential disparities, not proof of unfair treatment.

MediumClosing likelihood

We looked at how often a lender's applications end up as closed loans, not counting any that were denied or the applicant withdrew. At this lender, 90% to 95% did, which might mean some quoted terms changed before closing, some applicants stepped away, or both.

Importantly, this measure is not included in the scores because a lender's closing likelihood might be pulled down by factors outside their control, such as differences in application volume. Nonetheless, there are clear performance differences between lenders even after these factors are controlled for, so it is included for informational purposes only.

What Bankrate's editors think

Updated September 30, 2026

Alliant’s Advantage Mortgage program lets first-time buyers put 0% down on loans up to $650,000 with no PMI, and repeat buyers with 5% equity can often qualify with just 5% down. Ask about it directly — a generic rate quote won’t surface it.

On cost, Alliant charges less in added costs over eight years than rounghly 80% of comparable lenders we track. CFPB complaints run higher than average, though Alliant resolves enough of them with real relief to lift the score out of the lower tier.

You’ll need to join the credit union before you can borrow — typically through an employer, family tie or a $5 donation to the Alliant Credit Union Foundation.

At a glance

Good for buyers who qualify for the 0%-down, no-PMI Advantage Mortgage, especially first-time buyers who are short on down payment cash. Not a good fit if you’d rather skip the credit union membership step.

Great Experience Working with Alliant

We were skeptical of working with a completely digital bank, but we had the most pleasant lending experience with Jeff, Trinette and Deb. We would absolutely recommend working with Alliant to anyone who is shopping around for their mortgage.

Great Experience Buying First Home

As first time homebuyers we were very anxious going into this process. Our lender Jeff was very communicative and great to work with. He and his team (shout out Trinette and Sherri!) made the whole process very easy. Jeff also communicated well with our realtor and everything went very smoothly for us!
