Hello are you intersted in this house?
hi yes I am, how  many square fot
It offers 600 sf and if you add in the garage it is 900 sf.
sounds good, what year is the house
It was built in 1983 and it is a very well kept house!
what the roof's condition ? 
Its a little rough, but doable.
ok so lets get down to buisiness, how low can you let it go ?
I can sell it for 1845 a month for a 1 year price, or possibly lower if you are interested in a 2 year lease.
ok I m not  going to lie to you, I want three years but the price has to go down to 1600, is this fair enough
