Paying off LLC Funds Obtained from Personal Sources

[J Czar]

I have a question about funding a single-member LLC and paying it back. I have read several of the posts here, but I have not been able to figure out exactly what to do. I am buying a property, and I going to fund it with a cash-out refinance from an investment property and a cash-out refinance from my primary residence. I understand I deposit the money into the LLC as an owner contribution. How do I set up the monthly payments from the LLC to pay the installments while being able to deduct the interest as a tax expense?

For example, investment A has a $200k loan and my primary has a $200k loan. I fund the LLC for investment B with $200k, $100k from each property. How does the LLC pay me back so I can pay the two loans while having the LLC recognize that some of the monthly payments are for interest?
