Borrowing with an LLC as the borrowing entity is very typical in commercial lending. Many times the LLC is a special purpose entity formed to own and operate a commercial property for various legal and accounting reasons.
A commercial lender will typically want to get information on the ownership group of the LLC with a few exceptions. In underwriting any commercial loan the lender will want to identify three sources of repayment. The first repayment is the cash flow of the subject property, the second is the liquidation value of the collateral and the third is the possible recourse to the guarantors of the note.
Important to know when developing an LLC or investment entity to secure lending is that lenders have different approaches to underwriting. Some lenders may want all owners of the LLC to provide a full recourse personal guaranty while some lenders may only require a limited personal guarantee. There is also the possibility that a lender could require no personal guarantee but that typically requires a large down payment.
Since each LLC member will invariably be required to provide some sort of personal guaranty, you will need to provide tax returns and personal financial statements for all individuals. Depending on the circumstances of each individual, more information may be requested by the lender.
