I just recently got my citizenship here, my wife and I are very entrepreneurial and currently own two business’s.

I want to do this properly for taxes and asset protection, and legally, in case I want to pursue U.S. citizenship down the road. 

However, I'm from Bulgaria, have citizenship and go back fairly often to visit my family.

I know of some DSCR products that don't have citizenship requirements.I just did this for an investor in NY for a 2.5 million dollar STR on Indian Rocks Beach and it grosses 400k per year.

I was born here and have citizenship and grew up in the U.S.

One sort of solution I see for you wanting a higher LTV threshold is to potentially add a US citizen to the LLC (friend, family member, or business partner perhaps if they have US Citizenship) and have them as the personal guarantor on the loan.

Assuming you had to do a lot with customs potentially too, as well as potential citizenship requirements, etc. 

I have dual citizenship so I am going to assume this shouldn't be a hard task.

Since your situation involves dual citizenship, property ownership, and potential capital gains, it's advisable to consult with a qualified cross-border tax accountant who specializes in helping individuals like your Dad.

Expat from Japan here to study Japanese for a year earning an Associates Degree for a better chance at citizenship in Tokyo5.
