The SBA 7(a) loan is the most common SBA loan product, offering financing for virtually all business expenses. An SBA 7(a) loan is a good option for acquisitions, partner buyouts, real estate purchases, refinance and more. SBA 504 loans are long-term, fixed-rate financing for real estate purchases and buildouts. Our 504 loans can include acquiring commercial real estate, financing improvements within that real estate, and purchasing large equipment.
