I'm looking at structuring an LOI with both Forgivable seller note paid over 6 years (because of extremely high customer concentration) and a standby seller note(standby for 2 years then paid over next three). What would be the current norm for interest rates, with prime at 7.75 % ? Is there any incentive for the seller to accept lower rate than I can get from SBA lender? If this makes any difference, the seller is from EU(France).

Thanks
