Advice for funding the acquisition of an international software businesses?

Hi there, I' a self funded searcher looking to acquire a software business. I was initially interested in an SBA loan, but many of the most interesting companies I'm seeing have foreign tax returns and thus would be a headache for the SBA. I'm curious if anyone here has any suggestions for funding that would be similar in structure to an SBA loan but would be possible to use for the acquisition of an international company? Note that most of these businesses are fully digital so on acquisition I'd move all operations to the US.

Additionally, as I'm primarily targeting successful software businesses which tend to have higher valuation multiples, I'm also interested in meeting any investors looking to bridge gaps in loan funding.

Thanks for any thoughts and assistance!
