Hello
Hello!
Would you be willing to entertain offers for less than the asking price?
Yes, I would, depending on what the offer is, of course.
What about 2000 per month with an agreement that I would be locked into the rent for a longer contract?
No, I'm sorry, 2000 is just too low for the size of home, location and condition of the home. 
I'm sorry, I cannot afford as much as the asking price but love the house. It would be perfect for my wife and kids. Would you be willing to settle for 2200?
No, sorry, the lowest I could go on this and still make some money for myself would be 2900.
