Moving houses isn't just about packing and leaving your old home. Most often than not, you would have to sell your old home and buy a new too. Legalities are involved selling and buying houses. So it's a good idea to hire a real estate agent to help you.
 
First, a real estate agent would already know where to place your old home. He would know more houses for sale. He would also know all the procedures entailed in selling and buying homes. With his knowledge all you would have to do is to complete the documents needed for the sale. Of course, final decisions are always still left up to you.
 
For instance, you would have to talk beforehand about your requirements on your new home so he can give you a listing of homes that fit your needs. You would also have to tell him your budget and then how much you want for your old home.
 
It's always advisable to sell your old home first so you would have a definite idea on how much money you have for your new house. Just make sure that you negotiate for a longer closing date. Sometimes it's worth lowering the price a bit just so you could have flexibility and have enough time to buy a new house first.
 
In your search for a house, simply look into those that fit your budget. Have the house professionally inspected to know if you are buying a house of good condition and paying at the right price. This will also ensure that you will be able to insure it as well. Always ask time to review documents before you sign them. This will ensure that you are actually selling and buying the house at the terms that you most prefer.
