I'm interested in the studio you have advertised.
Great!  It's fantastic.  I'm asking $1700.
It looks like a great place.  I'd love to come take a look, but I am wondering if you might come down on the price?  Maybe $500 less?
I can't go that low.  I could go as low as $1600.  Would that help?
$1600 is still out of my range if I have to pay utilities, satellite, wifi, parking.  Are any of those things included?
We have ample parking and provide satellite and wifi.  How about $1550?  We'll also pay your deposit!
That's something I can do.  
That sounds terrific.  Looking forward to meeting you.
