Hi, I am interested in this house. 
Hi there - I'd love to sell it to you.  Make me an offer!
The price seems high compared to others in the area of this size. Would you accept $1325?
I can't go that low.  I can offer you $2200 and a free 5 year home warranty that covers everything.
I can't go above 2000. Would you take 2000 and no warranty?
Done!  Thanks for your business!
