buyint the seller's furniture (estate sale)

The seller wants to know if we want to buy anything in the house (including china, knick-knacks etc...) the seller is also a real estate attorney (it's his mom's house)

I don't have any idea what to offer!

There is a dining room table and chairs in good condition, a nice china cabinet, 6 additional random old (turquoise seat) dining room chairs, 2 old sofas, 4 older chairs (like for a living room), a few lamps, a few end tables and TONS of 'stuff'

Should I make a blanket offer? Should I offer on only the things I want?

What sounds like a good price? The thing is, I think whatever we don't buy they'll just throw out anyway!

I think you're right - he told me to make an offer but I'm not sure what to offer.

Should I just ask him to make a fair suggestion (on a price for everything) and then counter offer?

Man - houses are so expensive, I feel like telling him to just throw it in - I mean it's only going to go in the garbage anyway!
