Hello.
One thousand is my final offer, take it or leave it
1000 sounds okay. Can I at least come take a look at the place? (Note: 1 sentence will result in hit rejection)
Okay, yes you can come over to look at this. I will submit the 1000 in the final agreement then. Sound good?
Maybe. Is the place in good condition? 
Yes, ample closet space and all!
Sounds good. I would like to pay 1500 for it. How does that sound?
Okay, good, you have a deal
