Texas agents need to provide buyers and seller access to your MLS, the only reliable source of accurate, reliable, relevant, comprehensive and timely real estate data.
Don't be shy. Give active buyers and seller easy access.
Trulia, Zillow and all other "web" based real estate sites have no access to Texas sales data. In other states, this is public record...but not in Texas. They use county tax accessed values as their "sold" data. That could be off as much as 35%!
Your clients might question you on values as they are likely doing their own research on-line and using one or more of these sites. You have to get yourself educated on how these web sites operate VS your local MLS and review with them that a Realtor's data is much more accurate.

Zero, zip, nada ... they're not even close. This Trulia listing, my "default" example, should sum it up ... a 3300 sq. ft. home, built in 1999, located in a gated Clear Lake golf course community, valued at ... are you ready ... $98,000! The property actually sold in the $360's.
Since sales prices are not public information in TX, the only accurate source of comparison is HAR, where you get actual numbers, not some figures based on a convoluted formula which bears no resemblance to reality.
Run your own comps ... it's your best source of accurate information.
