RentPredict.com uses rental-payment histories and other data to produce scores for about 80 percent of Americans, even if they don't rent. Scores range from 1 to 999.

Atlanta-based RentBureau is kind of like a credit bureau for landlords. It runs the National Rental Data Exchange database that tracks residents' rental histories and collects rental-payment information every 24 hours from properties across the country. The data is updated daily and is available to RentBureau members as soon as it hits the company's system.

RentPredict.com -- introduced today at the National Apartment Association Conference and Exposition in balmy Orlando, Fla. (Does anyone actually attend conferences in Orlando? The pool is always calling.) -- is the company's newest tool. It was designed to offer owners of small- and mid-sized properties -- 70 percent of landlords, the company says -- a way evaluate potentially risky residents and avoid losses from tenants who skip out on their rent.

"Credit scores have always been combined with other information to report a person's financial history," Eric Hartz, CEO of RentBureau, said in a news release. "RentPredict.com is the first score to use detailed rental history and other data to forecast how likely that potential resident is to pay the rent."
