Quote from @Theresa Harris:
If you have section 8 telling you to ignore the letter (get it in writing) and the tenant said they'd be out by April 30, proceed that way. Other than the letter from section 8, is there any reason to believe the tenant won't move out at the end of April?
Tenant called me Wednesday morning implying they are helping me by staying in May with HACC paying the rent since I have no new tenant. I pointed out even if I have no tenant, I can show the place better when it is empty and she responded saying she will leave by April 30th. She also said she has additional forms from HACC for me to sign and I offered to come over the weekend to sign.
Evening I texted to send me the picture of the form I need to sign (I already signed the notice to vacate form 1st of April) and to tell me what time they will vacate and hand over the keys on the 30th, since I am planning to change locks the next day. Usually they are very good to respond, it has been 12 hours with no response. That is making me concerned. Emailed and left voice messages with HACC and no response till now(Not unusual).
