Chihuahua puppy

I have a puppy I need to rehome.
He is 3 months he was born 1/3/24.
He’s used to using puppy poopy pads.
Which he will come with what he has left.
He will also come with everything I have for him.
I have a new bag of food.
He eats science diet.
Cage which he hates.
Bunch of toys.
A car seat for the car.
Steps for couch and bed.
Beds that he doesn’t sleep in.
I paid 650 but would like to get back as much as I can.
500 obo.
Need to rehome asap.
Not sure how he is around other dogs but loves to play with cats.
