DealRoom is not a lender, bank, broker-dealer, CPA firm, law firm, or SBA representative, and does not make credit decisions. “SBA-ready” and “SBA pre-screened” labels mean a listing has been reviewed against available SBA financing factors, not that SBA or any lender has approved a loan. Final eligibility, underwriting, terms, and approval depend on the buyer, lender, full documentation, and current SBA rules.
