tenants always late--do we renew lease or not

[David Yuhaz]

One of our rental properties is free and clear, and the tenants have been in the home approximately 3 years.  This property is being taken care of through a property management company.  This past year, the tenants have ALWAYS been late, sometimes 30 days. Legal paperwork is always filed and they ALWAYS pay.  Problem is, their lease expires Feb 1, 2016 and my wife and I are not sure if we should renew their lease or not. Any suggestions or comments would be greatly appreciated.  Thank you.
