Hi and welcome to JA. I am Ray and will be the expert helping you today.
You can terminate the sale for failure to provide the commitment letter and failure to close because time was stated as being of the essence.If the folks are holding over you give them eviction
notice and pursue forcible entry and detainer.
I would send them the termination letter first and then a notice to quit and proceed to foreclosure if they will not vacate.
The two grounds here support a termination letter to the buyer for failure to provide commitment letter and failure to close when time was of the essence.
You may need a local lawyer here to force them to leave, file eviction if necessary.
I appreciate the chance to help you today.Please let me know if you have more follow up.
Since they are buyers/renters this is more complicated since you have to terminate and get them evicted.
