Going month to month at end of 1 year lease

[Bienes Raices]

My lease states that it goes month to month at end of the one year term.

My experience so far has been that tenants want a new one year lease, rather than month to month, because they're afraid of being told to leave or having the rent increased.

Normally I would offer the option of a new lease, but these particular tenants have been late (beyond the grace period) with the rent a couple of times now, and there have been a couple of other minor issues.

Would you take a chance on them moving out because of the lack of a long term lease, or take a chance of a future eviction/unpleasantness on a new one year lease, if things continue to go south in terms of on-time payments?

Thanks.
