If you have a lender you are comfortable working with or have a relationship with it's okay to go on your own. Sometimes, depending on the situation a Realtor can suggest some lenders that might be offering incentives. Choosing a lender is totally up to you as the buyer we can only suggest.
If you need the assistance of a buyer's agent I would be happy to assist.
