Recently I found these helpful links from the Texas Department of Insurance website.  It provides sample rates with different insurance companies for a variety of policies.  I am including the links for homeowners and auto but you can visit their site if you are interested in others.  The top insurance companies were required to submit their rates to the Texas Department of Insurance.
