Home appraisals a click away

Online database to hold details on properties nationwide

Ron Simmons is part of a team slogging its way from California to Chicago, one photograph at a time.

As the real estate appraiser and his colleagues inch down the streets of suburban San Francisco, they pause in front of every home and take its picture. One recent day, he photographed 900 buildings in seven hours.

"It was a good day," said Simmons, though he added that his feet hurt.

Simmons and a half-dozen employees of his appraisal team in Antioch, Calif., have been on Northern California streets since February as part of a cross-country journey undertaken by the Zaio Corp., an upstart in the staid appraisal business that is tackling the mind-boggling task of photographing every building in every city in America.

"Our objective is to be photographing 100,000 [properties] a day before June 1," said John Ross, vice president for market development strategy for the Canadian firm.

Digital photography has changed the way people chronicle their own lives, and it is transforming the way real estate business is conducted.

For the appraisal industry, technology is roiling the waters even more. Zaio's emergence comes as traditional appraisers are feeling pressure from AVMs - automated value models - which are essentially computer programs that blend assessor and market data to generate appraisals. No human appraiser visits the house.

Zaio's plan - which has its supporters, its skeptics and its critics, especially in traditional appraisal circles - is to meld upward of 100 million pictures with assessors' data and its own valuations to create a nationwide database that can churn out certified property appraisals in an instant.

"It would happen about as quickly as the lender could type your address in," Ross said. He said the idea is to "pre-appraise" America's homes to compress the process for obtaining nonpurchase home loans, such as refinances, into a few days.

"It could revolutionize the appraisal industry, no doubt about it," said appraiser Tim McCarthy, chairman of the Illinois Real Estate Appraisal Licensing Board. "They're taking appraisals and the art of valuation to a whole new level. But appraisers are conservative by nature, so we wonder if they can do what they claim."

What Zaio claims to be doing is automating the process while incorporating the appraiser's judgment.

A kind of "instant appraisal" is available in the marketplace in the form of AVMs, the best-known supplier of which is Zillow. But AVMs are based on algorithms of public data, and their critics say they are unreliable - more an estimation tool than an appraisal.

Zaio, instead, is trying to reinvent the "drive-by appraisal," in which a trained appraiser visits the property, photographs it and evaluates its exterior, based on industry-accepted criteria.

Drive-bys are often used for refinancing, home equity and other loans that typically do not call for the more rigorous, full-walk-through appraisals usually needed for a purchase loan. Producing a drive-by can still can take a week, Ross said. And the delay sometimes derails deals that are well under way, as appraisals trickle in that do not match expectations, he said.

Banks also don't want loan applicants to wander off because another lender has made a better offer, McCarthy said.

For Zaio, starting up is a huge undertaking that will cost about $75 million, Ross said. It plans to photograph every property, including commercial buildings, in 250 U.S. metropolitan areas.

They say that photography is largely complete in a half-dozen cities and has been started in a handful of others. After the photographers finish, Zaio matches the pictures in its database with appropriate public records. The company plans to complete all 250 metro areas by 2010.

Zaio divides each city into zones of about 10,000 properties and is selling appraisers the exclusive right to such zones for $9,200.

Appraisers who have purchased zones will walk them, using a proprietary system to assign a score to each property, and update the data regularly so that an instant appraisal can be produced when needed, Ross said.

Databases are operational in Mesa, Ariz., and Spokane, Wash.

"The numbers it generates are great," said Todd Powell, president of the Spokane Firefighters Credit Union, which has saved money using the system on loans. The credit union pays $125 for a Zaio appraisal, instead of the $300 to $350 for a traditional one.

"But not every area is covered by it; it doesn't have data for homes in rural areas," said Powell. "You have to maintain a relationship with an appraiser. You're not going to fully rely on this system."

He said Zaio-appraised loans can be completed in three to five days, compared with a couple of weeks for the traditional process.

The appraisal community isn't sure what to make of Zaio, said McCarthy, who added that he plans to hear out company officials.

"Zaio can be viewed as competition or as a potential avenue of new business," he said. "It's a bit of a gamble. Can appraisers make money on it? I don't know."
