For SBA lenders
Short answer
To amend a 7(a) loan authorization for project cost changes, lenders must provide a revised project cost breakdown, justification for the changes, and updated pro forma financials if the changes are material.
Material changes to project costs post-authorization require an amendment to the SBA loan authorization. The lender must submit documentation that justifies the revised cost structure, such as new invoices, revised estimates, or an updated schedule of sources and uses. This ensures the loan remains compliant with SBA's use of proceeds rules.
After authorization, a borrower discovers that construction costs for a renovation project are $50,000 higher than initially estimated. The lender would submit an amendment request with revised contractor bids, a new project cost breakdown, and a memo explaining the necessity of the increase.
Insider move
Lenders must ensure that any changes to authorized project costs are fully justified and documented, as significant deviations can affect the loan's eligibility or repayment ability. Unauthorized changes or insufficient documentation can result in a guaranty repair.
