The Commercial Real Estate Show addresses the question of whether one should personally guarantee a lease for his or her company.
The answer is no, if you can get away with it, as there is no benefit to a tenant. However, practically speaking, most landlords will require a personal guarantee for a small business. That being said, it never hurts to ask, and if you’re truly willing to walk otherwise, you might be pleasantly surprised. If you don’t ask, you don’t get.
