Tenant Terminates Lease early

[Fernando Roman Romero]

I have a tenant who terminated their lease early in writing due to medical reasons. They have called me back a couple of times asking me if the property was still available because they might need to come back. It has been a little over 2 weeks since they have moved out and are now wanting to come back to the property. I have already put the property up for lease but have had no applications turned in, only phone calls and text messages about the property. 

The tenant who wants to return has also been a very good paying and clean tenant. Just wanted to ask if I should let him back into the property? Should i continue off the same lease or create a new one? Are there any consequences I should be aware of?
