Private Funding for My Business

[Jon Robinson]

Hi, I was recently offered from a client/friend a generous amount of capital for the next 5 years at a great rate to invest. These funds will primarily be used at my discretion for acquisitions as I scale my business. I currently have a successful real estate investment business that is essentially a portfolio of STR/LTR rentals that I hold under my LLC. The LLC consist of just my wife and I owning 50% , and my 2 children as 25% each. What is the best way to write up the paper for this debt, would it just be unsecured debt, how could I secure it without changing the ownership structure of the LLC?
