<human>: Can you succinctly summarize the text in 1-3 sentences?

I want to help my sister move here but I feel like she's jumping the gun. Our mom is sick and she wants to be close to her and help dad after she passes away... Parents live next door.

 It all just seems to fast and a little fishy. I haven't heard from my sister in years really, beyond Facebook. Which isn't very good correspondence. 

I've tried to tell her that her husband needs to find a job before moving or they might get stuck, but she has an excuse for everything I say. He needs to be here for interviews. They can't afford the drive (about 500 miles)

Well they have $5000 in savings but how long will that last when they get here? Why can't he just drive here for interviews with savings?? I support my daughter and myself alone and can't afford her whole family.

I'm not comfortable with  this move but can't seem to get her to understand my point of view. I have a three bedroom trailer and I know her kids will wreck it. This is crazy right? Aren't you supposed to find a job before you move???
<bot>: my sister is trying to overtake my small, quiet home and move her family of five in. How do I kindly say no??
