Best Mortgage Lenders in Idaho
Data-driven picks for Idaho buyers
Buying a home in Idaho? Whether you’re settling in Boise, Twin Falls, or a growing rural town, the market is moving—and so are prices. With limited housing stock and more out-of-state buyers entering the mix, choosing the right mortgage lender can give you a serious edge.
To help buyers make smarter choices, we analyzed closed-loan data from hundreds of thousands of loans across 65 different lenders operating in Idaho. Our sample included 30-year fixed, conventional primary home purchase loans. You can see the full TrueRate analysis. These aren’t teaser quotes or advertised rates—this data reflects the real rates and fees buyers locked in.
Each lender listed below consistently outperformed the state median on pricing, while also offering competitive products and solid borrower support. We also categorized lenders to help you find the right fit—whether you’re a first-time buyer, looking for a digital-first experience, or need something more specialized.
Tomo Mortgage
Why it stands out
Ok, we’re a little biased, but the numbers speak for themselves—low rates, no lender fees, better reviews. Tomo Mortgage was founded in 2025 by former Zillow execs who saw what was broken in the mortgage industry (think bait-and-switch, inflated rates, a black box of confusing fees) and set out to fix it. It was ranked Best Online Lender 2025 by Bankrate, earning strong customer reviews, and is backed by major financial services companies. With historically some of the lowest rates of lenders who operate in Idaho—you can see the full methodology above—borrowers are likely to see large cost-savings.
Having the lowest rates also means Tomo Mortgage can be more upfront and transparent about its rates and fees. You can get personalized rates online without applying or speaking to a sales rep. Its rate tool includes a slider that shows how your monthly payment changes with and without points—something most lenders won’t show unless you’ve already started the loan process. That level of visibility puts Tomo borrowers in control from the start.
