I had belatedly realized that FHA goes off personal credit and therefore I couldn't use the LLC for it.

Utilized a low down payment loan, maxed seller credit, tax proration and closed on the 1st of the month to maximize my cash and acquire this property What was the outcome?

It would benefit a lot if you are able to obtain US credit, US LLC and US Bank Account.

Got an equity line of credit and borrowed from it to pay cash for the property.

Quote from @Zach Edelman: If you do a DSCR loan and vest it in an entity - you and your partner can both PG the note and it will report to neither of your credit reports, thus having no impact on your DTI! 

DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.

At it's basic level:Assumption: Asking the bank to turn the loan over to you and going through the normal underwriting process, credit, income, DTI ratio etc SubTo: Taking over the loan without telling the bank, no underwriting, no credit check, no income verificationBoth have risks, but it's not my intent to be detailed in this post.

Let them pay the deposit with a credit card.

As for non-bank loans, I'm familiar with a loan program that provides 100% financing, but it requires a minimum 650 credit score and proof of funds covering 12 months of interest.

Although I've considered a future line of credit against the property as my best long term option, I would need to pay down the remaining balance first.
