Tenant wants section 8- I want tenant out

[Sara Maree]

My tenants are on a month-to-month lease. I am going to sell my condo soon, and I was planning to post the non-renewal notice September 1st. I just got a text from the tenant stating she is now eligible for Section 8, and she wants me to go through the process to be able to accept vouchers. 

Should I tell her via text that I plan to sell, and she should start looking elsewhere? Should I not respond at all and just post the notice today?
