When dealing with "small business" commercial lease agreements' typically the landlord will require the "personal guaranty" of the small business tenant. The landlord requires that I sign a personal guarantee, or provide a 6-month security deposit, to lease the space.I have a personal guarantee in a commercial lease for my business (LLC) and I have defaulted and I need help to find. A personal guarantee means that the business owners or individuals who are acting as guarantors will be responsible for making the lease payments. A Personal Guaranty is a guarantee of term, meaning that it remains in effect for the full duration of the lease. The general rule is that a personal guaranty is to be strictly construed and a "guarantor should not be bound beyond the express terms of his guarantee." Operating expenses, real estate, taxes, insurance. Most leases are personally guaranteed. It would take a landlord to fill the space. So these are highly advisable.
