One report says many homeowners carry a standard HO-3 policy, and that can become a problem once a property is used for income.
That is the key risk. The rental income might look attractive for a major event, but the exposure changes the moment money changes hands. For many owners, that is not obvious until they read the small print.
The same report says the danger is not limited to one rejected claim.
That turns a quick World Cup windfall into a much costlier decision. For homeowners with a loan on the property, the insurance issue may matter as much as demand, pricing or occupancy.
The practical advice appears straightforward: speak to the insurer before advertising the home.
Some providers may offer an add-on or separate short-term rental cover, but the report says that usually needs to be arranged in advance. It also notes that host-protection programmes offered by rental platforms do not necessarily solve compliance issues with a homeowner’s own policy.
As North Texas moves closer to the World Cup, this looks set to become a bigger off-pitch story. The next thing to watch is whether local homeowners adapt early - or only discover the risk when the first claims arrive.
