The 20 best money Web sites
These sites have tools you can trust to help you make better money decisions.

This big real estate site lets you zero in on homes whose sellers have cut prices recently -- an indication they may be ready to jump at your offer -- and instantly tells you how far they've come down. A host of such well-designed tools distinguishes Trulia from worthy competitors Zillow.com and Realtor.com. (No harm checking them all, though; their lists overlap but aren't identical.) Another great Trulia tool: Heat Maps, which display average list and sale prices within zip codes.
Coolest feature: Snapshot.Trulia.com puts a neat visual twist on the usual listings. Move a slider to select homes by price or their time on the market; their photos pop up on a map. It's a bit hypnotic, actually.
Try this too: Forsalebyowner.com for listings that big sites won't have.
