About the editor

Samprit Biswas

Samprit Biswas builds and edits InfinityRateWatch: the engine that turns public data into each day's estimates, the refinance check, and these pages. InfinityRateWatch is independent: it is not a lender or a broker, and no lender pays for what it shows.

How the pages are checked

• Every number comes from the engine's daily run, which checks each source and refuses to publish anything that fails; no number is typed by hand or written by an AI model.
• Every number names its sources and their dates, and a test fails the site when one does not.
• The refinance math in your browser is held, case by case, to the engine's own results.

Review

A credentialed reviewer, a licensed or retired loan officer or a certified financial planner, will read these pages and be named here. Until then, the methodology is set out in full so anyone can check it. Methodology
