LOI fell through...what next?!

The LOI I submitted was not accepted (seller went with cash buyer vs. my SBA offer). Understandable but disappointing. I haven't seen any other immediate deals available in the areas I was looking. My intent with the last deal was get the LOI done and then pursue investors for the equity portion of the SBA. What are some suggested next steps for a self-funded searcher like me? Should I work to secure investors without a specific deal in hand?
