Non-SBA qualified Transactions

I'm looking at a deal that is not eligible for SBA financing as the business line is coupled with other business lines within the organization. The seller is looking to separate it out but may take time. Given this will be an asset sale, I assume there is opportunity to move forward to split the assets from the existing business. This situation posses a challenge as I am looking to finance 90% of the transaction. Does anyone have any recommendations of alternative financing vehicles that could be used to complete this transaction? One thought is using more conventional financing at a higher rate for 6 months and then refinance the business with the SBA at a lower rate. Otherwise perhaps there are other hard money options which again would be more costly. Would love this group's feedback on any creative options as well as contacts to any lenders who could help facilitate the transaction. Thanks!
