More like ensuring people have cheap housing when they get there. In the current system any UBI to help people move to a new place will be consumed by the increase in housing prices.
Take that thought one step further: an increase in housing prices will essentially keep the status quo in a given locality (unless more housing is constructed), so the people who couldn't afford housing before the UBI would not be able to afford it after the UBI.
The only difference is that now they have money to be able to afford a U-Haul and/or plane tickets and/or any other funds necessary to uproot their life to a more economically friendly place.
That is a small improvement and rational in some ways - go to where their money goes further - turning a race to the bottom im their favor for once.
Unfortunately it would probably not be that great for growth long term and effectively create ghettos away from opportunities and such a concentration would be less able to support services when comprised of the lowest end. Better than homelessness certainly but....

There's no empirical evidence of this happening anywhere else. The European Union and Switzerland are both thriving examples of decentralized governance with totally open borders and free trade, and they don't appear to have such "ghettos". Insofar as the EU has problems, it's that the Member States are starting to get skeptical of its power concentration.
I would even argue that the US today has economic ghettos because it is so centralized — it has a financial center, it has a tech center, it has a couple media centers, and everything outside is barren "flyover country".
