No. Typically, costs are minimal and may include:

Bank’s “out of pocket” costs (appraisals, credit reports, title reports, lien searches, etc.). The lender will usually request these fees be paid at the time they issue a commitment letter--before the SBA loan application package is prepared and before bank approval of the loan request. These fees are generally a few hundred dollars, depending on the specifics involved in a particular loan request.
Loan packaging fee (generally $1,200 - $2,500). The SBA monitors and regulates fees charged for the preparation of the SBA application file, typically referred to as the "loan package." These fees must be usual and customary, and must be based on the time and expertise required to complete the loan application package. The SBA strictly prohibits the packaging fee from being contingent on loan approval. For this reason, the loan packaging fee is collected prior to the formal approval of the application.
SBA Loan Guaranty Fee.
This is usually the biggest expense involved with obtaining an SBA loan. The guarantee fee is charged by the SBA--not the lender--and is based upon the guaranteed amount of the loan. The fee ranges from 2% to just less than 3.5% of the guaranteed portion of the loan.
What portion of the loan is guaranteed by the SBA depends on the use of proceeds, the amount of the loan requested, and several other factors. Most SBA loans carry a 75% guarantee.
For instance, if your loan is for $200,000 and carries a 75% SBA guarantee, your SBA Guarantee Fee would be 2% of $150,000, or $3,000. This fee may be paid after the loan is funded and may actually be included in your loan request.
