[Q]: Seller: Hello, are you interested in this bike?
Buyer: Hello, I am interested in the bike.
Seller: Do you have any questions about it?
Buyer: It seems like it's in great shape, but are there any issues with it that aren't listed? I am on a budget on what I can spend so I need a good deal please :)
Seller: None, at all. Like I posted it's all custom built and if you have issues you can bring it in and we'll fix it for you. 
Buyer: Okay, sounds good. I would like to offer 485 for the bike. I know it may sell new higher, but even though it's a great bike, it's still used so more likely to have some issues pop up sooner.
Seller: Yes, not going to be able to do it at that price. The parts cost more than that. 
Buyer: Well, as I really am on a budget, I can go up to 532, but that is really the most I can pay for the bike. I just can't afford a higher price.
Seller: The lowest I can go is 600.
Buyer: Let's meet in the middle at 550 and that would work out well for both of us.
Seller: Ok that works for me. Thank-you.

Buyer: what does the 2425 include? Does that include all utilities etc?
Seller: yes, water, trash, all included in the rent, but you have to pay for your electricity. 
Buyer: the other ad was also for a 2 bedroom but it was only 1800. Can you match that price?
Seller: 180... yikes. it must be in the ghetto. thre's no way i can do that. tell you what, if you sign the 1 year lease, i'll let you have for 2300/ month. 
Buyer: What if I sign a 4 year lease I plan to put down roots. I can go up to 2000 but that's really the most I'd be able to spend.
Seller: you know what? that's a deal i can do. 2000/mo for 4 years deal.
Seller: whoa. man. why did you leave?
