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 wanted to fix what was broken in the mortgage industry. They did away with bait-and-switch prices, inflated rates, and confusing fees. It was ranked Best Online Lender 2025 by Bankrate, based on its strong customer reviews and backing from major financial services firms. Tomo historically has some of the lowest rates among lenders operating in Washington D.C.
Lower rates drive more transparency: you can get personalized rates online without applying or speaking to sales. The rate tool includes a slider that shows how your monthly payment changes with and without points—clarity and control from the start.

What borrowers say
Customer reviews of UNFCU’s mortgage services are split between glowing praise and deep frustration. Praise focuses on personalized services and low rates, while the negative centers around bureaucratic and slow processes as well as communication.
“ Not only did he get me lowest rate on an ARM anyone had ever heard of at that time, he held my hand every step of the way, answered all my questions and calls, and soothed all my anxieties about being a disorganized client. When I closed, all the lawyers oohed and aahed”
“With certainty I do not believe we would have been able to acquire this home without her thorough knowledge and experience. She also beat other lenders with our rate – there was no competition there.”
“Very slow and bureaucratic process. Our friends with other banks could get things done much faster, both for their original mortgage and for refinancing.”
AimLoan
Why it stands out
Founded in 1998 as one of the first fully digital mortgage lenders, AimLoan (American Internet Mortgage) built its model on automation to cut costs and offer some of the lowest rates, especially for conventional and jumbo loans. Many customers praise its quick, as-quoted closings, but service can be slower—particularly after loans are transferred. Best for rate-focused buyers who prioritize efficiency over hands-on support.
