You are allowed a max of 2%. Lender pays 3/4 on back end.

Show me on SBA From 159 that allows 2% Fee -

BTW - I never had any SBA Bank pay any so-called "Back-End" fee -
My Agent-Broker commission is disclosed within the closing documents which is paid to me by the bank.

I've spoken to many Banks that underwrite SBA Loans (many do not deal with brokers) but, never has a discussion
evolve around back end commissions.

I'm curious - how do you write 504 Loans?

"504 loans are available through Certified Development Companies (CDCs), SBA's community-based partners who regulate nonprofits and promote economic development within their communities. CDCs are certified and regulated by the SBA."
