Seller: how are you
Buyer: Hello, I'm great. I'm interested in your apartment, can you tell me how many square feet it is?
Seller: 100 sq'
Buyer: Wow, that's much smaller than I thought. And it does not have a washer/dryer inside the unit? Is it shared with the other people in the complex?
Seller: Yes they are shared. I am willing to lower the price a little, make me an offer
Buyer: Okay, will you take $900? 100 square feet is just much smaller than I anticipated but I guess I could squeeze my bed in there if you'll drop the price a bit.
Seller: I can go to about $1300 but that is probably my lowest. The location is amazing
Buyer: Yes I see that the location is great, does that 100 square feet include the bathroom or is that additional square footage?
Seller: Sorry, I meant the bathroom is 100 sq ft :) total is about 500 sq ft
Buyer: Ohhh okay, that's much better. I was a little concerned! Okay, how about will you take $1200 for it and I will bring the money and ID to apply today?
Seller: Sounds good, $1200
Seller:
Buyer:
