Straight answer
What does a real estate agent in Houston need on their website?
A site that's fast on mobile (that's where most buyers search), bilingual, with your listings presented well and forms that capture whoever wants to buy or sell. Plus local SEO so you show up when people search "homes for sale" in your area. 53% of people abandon a mobile page that takes more than 3 seconds to load.
