Tenant stalling on rental inspection before lease renewal

[Jay Mayer]

If your tenant has notified you that they would like to remain in the property for another year and you have agreed that they stay via email a little more than 30 days before lease expiration, but when you ask when is a good time to do a maintenance inspection (before signing the lease), they stall and take a while to get back with you. 

Also, lets say this inspection finally happens just 2 weeks prior to their lease expiring and I find they have not taken care of the home and do not want to renew the lease because of that. 

Would I need to give them an extra 30 days from making that determination, despite the fact that they stalled the inspection and allowed it within the 30 days notice one should give? 

I appreciate any clarification that may help me move forward if this happens. Thanks
