Two streets in Houston can be different markets, because the city has no zoning and sells by neighborhood and by what a builder will pay for a lot. In Bellaire, many sellers talk to buyers who plan to knock the house down and rebuild.
In Katy, Cypress and Fulshear, the homes come from large subdivisions, so a seller may see a dozen agents listing the same floor plan. HAR.com, Zillow and Realtor.com show sellers who is active, but the portals do not send listing clients to you.
Flooding sits in every conversation. Texas sellers fill in a disclosure form that asks about flood history, so a seller wants an agent who talks about it calmly. Put that on the page.
