Tenant defaulting rent payment

[Suresh Ram]

My tenant has been missing timely rent payment, explaining her financial hardships. In an effort to change the tenant I said i need to sell the property once her current lease ends by Dec 31st. She sent a notice asking to deduct the rent from security deposit to which i responded over an email asking to pay rent and the deposit would be refunded after their departure upon assessing the property for damage if any made by them. She has not responded yet. I'm worried that the tenant is going to default on rent payment and that she would not vacate the property. I would like a consultation to explore my options legally. What would you recommend in this situation?
