Attn Minnesota brokers/ property managers screening question

[Joseph Hammel]

I'm doing verification on a tenants rental history and their current landlord/ company said they won't give out info about them because they haven't put in notice yet. This seems pretty draconian. They won't be moving until March or April so they have time to put in a 30 day notice. With the tight rental market it's prudent to secure a rental before leaving your current one. Is what the current landlord doing even legal?
