Where to shop for a mortgage

Three mortgage-comparison calculators - and what they're best for.

Zillow.com

Best for: Vetting lenders and brokers. You can sort rate quotes based on user reviews.

The catch: Quotes are posted to your online account, so the rates may be out of date after a few days.



Mortgagemarvel.com

Best for: Finding the most current rates. The site updates them in real time.

The catch: The quote tool doesn't let you input your income. If yours is too low for the loan you want, you may have trouble getting approved.
