If you list your home or condo with a Realtor and they sell it, the rule of thumb is that your closing costs will be about 9 percent of the purchase price. Typically, 6 percent is real estate commission and 1.78 percent is State Excise Tax. Title Insurance and Escrow fees make up the rest. In addition, other fees can arise for attorneys, pest inspections, and the like, but these can typically be avoided with good planning and preparation.
