Section 8 tenant does not want to leave after lease expires

[Marisa Alvarez]

Section 8 tenant, section 8 pays full rent. Lease expires March 31st. She has 5 kids ( kids have been destroying the house so I did not renew after 2 years )

I have new tenant selected for mid April after I fix up the house. ( she is great and I don’t want to miss the opportunity of having this tenant)

Current tenant says she hasn’t been able to find a house so she can not leave because she can not be on the street with her 5 kids.

What can I do ???
