Section 8 tenant not paying their share of rent need advice

[Lana Ly]

Hello fellow landlords,I rented my house to a section 8 family to the mother and 2 kids who are over 19. They all work and HUD determined their share and it is more than HUD pays me. Well the first month the rent was due my tenant replied to me on the 5th that she had a heart attack and would pay in a week. Kept delaying when finally we had a call and agreed with her that they would pay at the end of August rent for August and then on September 20 rent for September and starting October regular payments on the 1st. I told them if they can't afford my house they can leave and it's ok. They said they want to stay. Well, it's September 4th and I told them that on 5th I will contact a case worker and start eviction (service Notice to vacate). I also offered them to move out this week and just pay me for August. I don't understand - they moved to the house because they didn't want to live in projects to improve their life and now they just ghosting me. Should I write a daughter to let them know I am not paid yet?

I told them to contact HUD to lower their portion if she was unable to work, contact RAFT, apply for disability. Need any advice. What should I write to a case worker, should I use a constable to deliver a note. Should I go visit a property? I used to have tenants who had temporarily troubles and when they asked to pay at the end of the month one time they always did.
