I'm pretty sure a renter does not need to provide 'cause' for moving out, after satisfying the rental-agreement contract-specified terms for giving notice, etc.  What if the property owner really likes the renter--who always pays rent on time, has a stable job, is clean, quiet and respectful to neighbors--and the owner really depends on the rental income, and it would be a cost and burden to find another tenant, who might not be nearly as good of a tenant?  Will the new rental laws restrict no-cause move-outs by tenants?
