4 SBA loans have financed At&T Wireless locations since 2008, written by 4 different lenders across 4 states. Half were approved for $336K or less, the mix is a mix of 7(a) and 504, and 0% went to owners whose business was under two years old.
A lender that has already underwritten this brand knows the unit economics, the build-out costs, and the franchisor. That is worth more to you than a bigger bank starting from scratch.
