Input:  Person1:       How is your house hunting going ? 
 Person2:Not very well . I haven ’ t found anything within my price range yet . 
 Person1:        How much are you looking to spend ? 
 Person2:I can only afford about 300 pounds a month . 
 Person1:        Looks like you ’ re not going to get more than a bedroom in a shared flat with that . 
 Person2:Really ? That ’ s a lot of money to pay for one room . 
 Person1:        Well , if you want to live in London , you have to pay the price ! 
 Person2:Do you know of anyone who needs a roommate ? 
 Person1:        I can ask around at work . Do you have a preference for makers or non-smokers ? 
 Person2:I ’ d prefer non-smoking roommates , but I guess I ’ ll have to take what I can get ! 
 Person1:        How long do you want to sign a contract for ? 
 Person2:I can sign a contract up to a year . I don ’ t know where I ’ ll be after that . 
 Person1:        Do you need a furnished or unfurnished apartment ? 
 Person2:I don ’ t have any furniture , so it ’ d be great if it were furnished . 
 Person1:        You know that you ’ ll have to pay utilities on top of the rent , right ? 
 Person2:No , I thought that would be included in the rent . 
 Person1:        It ’ s not usually included , so you ’ ll have to factor in about 100 pounds more each month for utilities . 
 Person2:I don't think I can afford that . 
 Person1:        Don ’ t worry . Sometimes people will give you a discount if you promise to do the cleaning or take care of the children . 
 Person2:That ’ s a good idea . I ’ ll look into finding something like that .
