New Mexico remains one of few states that shield property sales prices

Mar. 21—Anyone who's ever gone down a real estate rabbit hole knows the drill.

Maybe your neighbor's house is suddenly on the market, or you hear your favorite restaurant is getting a new landlord. You turn to the internet, address in hand, to see what you can see.

Between commercial sites like Zillow or Redfin, and government sources like the county assessor or clerk's office, there's lots at your fingertips: listing price, owners' names, square footage, liens, even satellite images or photos of the property.

But there's one piece of information you can't find in New Mexico, at least not without the help of a real estate agent or broker: What the property actually cost the last time it sold.

New Mexico is one of only about a dozen or so states that hides real estate transaction prices from the public. Those prices are available only via "multiple listing services," private databases maintained by real estate professionals.

Shielding sales prices from the public creates an unnecessary barrier to New Mexicans with an interest in buying or selling property, and makes it harder to get an accurate sense of what property is actually worth, according to Reilly White, an economist and associate professor of finance at the University of New Mexico's Anderson School of Management.

"It really limits the availability of information for fair pricing ... into sort of the hands of a select group of real estate agents that have access to these systems," White said.

But bringing more transparency to real estate sales prices would mean New Mexico buyers and sellers giving up some privacy, as well as real estate agents' exclusive hold on a key piece of information. The most recent legislative effort to bring more transparency to real estate transaction prices was unsuccessful.

Whose business is it, anyway?

Across the country, making real estate prices available to the public is the norm, but New Mexico isn't the only state to buck that trend. The largest is Texas, but Utah, Idaho, Wyoming, Montana and Mississippi are among others that keep purchase prices under wraps.

State Sen. Steven Neville, an Aztec Republican and longtime Realtor, said he doesn't think it's a coincidence that, with the exception of New Mexico, states that hide or limit sales prices run from red to deep red.

"I think the conservative mindset says, 'This is personal information,' " Neville said. "That's the attitude. ... I don't necessarily agree with it."

Neville said in many states, that mindset has evolved as taxes grew and became more complex.
