Problem: I think this spring is a good time for us to start looking .  We should plan to move out of here before July . I'm tired of living in apartments .  I know , dear . I am too . But we've just been too busy to look for a house .  We need to find a good realtor .  Not necessary . If we use a realtor to find a house , it will be more expensive .  What do you mean ?  Realtors always get a commission . If the realtor helps us find something , we have to pay him .  But doesn't a realtor help with the contract ? I thought they take care of all the legal troubles .  Yes , that's often true . But you have to pay them .  I still think we should have a realtor . We're new in this country . We don't know all the laws of buying a house . And also , the realtor will inspect the house . He can tell us if the house has any problems .  Of course we need a house inspector . But we can hire an inspector on our own . As for the legal problems , I have friends . They can help us .  So how can we find a house if we don't have a realtor ?  It takes a little more time . We have to check the ads in the paper . Probably also there are special real estate magazines with ads . Then we have to drive to the homes and look at them .  And doesn't the person selling the house have a realtor ?  Sometimes they do , sometimes they don't . It's best to find someone who is selling by themselves .  Why ?  That is because if the seller has a realtor , their price will be higher . He will have to pay a commission to the realtor .  Hmm . It all sounds very complicated .  It is . But buying a house is very important . So it takes time . That's why we haven't done it yet . It's very troublesome .  I want to look in the papers today . Maybe we can see something we like .  All right . I'll buy a newspaper when I go to the drugstore .

No
