If you wanted to buy a house I imagine you could easily be able to describe the house you desired to a realtor. After all, the realtor must have some idea of your taste and more specific criteria to search by. It might be a three bedroom, two bath, one-story house in a certain part of town. I bet you would also know how much money you would be willing to spend and an idea of where you could afford to live. You would probably realize that a 3 bedroom, 2 bath house in University Park or Southlake would be priced differently than a house in other parts of Dallas. You would figure that a house with a four-car garage and a pool would have increased appeal and higher pricing because of those features and might be more difficult to locate.
Specifications for printing should be just as carefully considered. Can you describe the general specifications of what you want and how much you have to spend? If not, you should.
