The SBA 7(a) Standard Loan is a popular choice for its quick turnaround (5-10 days) and sizable loan amount of up to $5 million. The SBA guarantees this loan for up to 85% for loans less than $150,000 and 75% for loans greater than that amount. Interest rates and collateral requirements are negotiated with lenders but are subject to SBA guidelines and caps. Generally, 7(a) loans require a 10-20% downpayment and all loans greater than $25,000 must be collateralized.
