Ｉhave a tenant who has 3 months lease with me. She live in a 3B/3b. the smallest one . Her lease ended on 6/15. 7/1, I sent her an email, and told her she maybe continue to stay in her current small room. Or she can move to upstairs, the biggest room． She replied me in email, she may want to move upstairs. But we haven't talked about the pricing and terms for the bigger room yet. Few days later, I only can give her the small room or the middle size room in upstairs due to my business.
She want to solve this problem by law as I sent her email to tell her she could stay either of these two rooms. But we haven't sign the contract yet. By law, do I have to rent her the biggest room as the email already gave her that option.
