@Scott M. I meant a lease. Below is a timeline if it wasn't clear above.
1.As i mentioned above my current tenant gave me a 60 day notice saying she wants to move an wishes not to renew her lease. She didn't say why.
2. I advertised my apartment and found a new tenant.
3.The new tenant passed all the background, credit checks etc.
4. I offered him a lease which he signed.
5. AFTER >The current tenant said she was in the process of buying a home which is why she wanted to move and that she is having issues with her coop appraisal and that she might loose the deal so she might need to stay in the apartment.
6. i have a tenant who signed a lease to move in December 1st and another tenant whose lease is expiring Dec 1st who now says she doesn't want to move incase her purchase falls through.
Question: how do i handle this situation and what are my obligations to them? I told the current tenant in my apartment that she should honor her 60 day notice and move out but she is saying she will be homeless if she can't purchase this home and has to move out of my apartment at the same time.
