yes you can use the same realtor to buy a home and sell your own, but make sure they are qualified to sell on both sides of the fence. some realtors are more qualified at working with buyers than sellers, and vice versa, good luck.
Yes, you can use the same realtor to sell and buy a home. You would want to make sure that they are knowledgeable in both market areas and know how to properly market your home that is for sale and is also familiar enough with the market that you intend to buy a home in. I advise that you interview the prospective realtor and make certain that they can fulfill your needs in a manner that you will be satisfied with. I hope this helps you with your question.
