This is an issue with the concept of basic income. Likely the most equitable solution would be for government to step in and provide housing directly or limit rents in some areas.
The federal basic income level would likely be based off of a national averages for cost of living, with state/city governments stepping in to provide greater subsidies if they feel it's needed. People may still need to pay more for convenience, but should have other options available, even if it means moving an hour or two away from the trendy metro areas.
