Houston does not have a single tourist core. Demand is spread over events, hospitals and industry.
NRG Park draws crowds for rodeo season and big conventions, the Texas Medical Center fills rooms with visiting families and clinicians, and Clear Lake leans on the space and energy sectors. Owners in Montrose, the Heights and EaDo often hold small bungalows, townhomes or condos.
Their first question is whether the rules allow it. The City of Houston has short-term rental rules that cover registration, and condo rules or deed restrictions may block it altogether.
Your marketing must be honest about that, and it can offer furnished stays of 30 nights or more as another route.
