Glenn S. Demby

The word “reimburse” means to pay back. So, requiring reimbursement may preclude you from collecting the tenant’s pro rata share until after you actually pay the tax bill.

Don't Leave Blanks in Printed Lease Forms

Jul 3, 2024

If you use a standard lease form that includes blanks for listing appropriate information, don’t leave any of the blanks empty. If you do and end up in a dispute with a tenant, you open the door to the court’s interpreting the meaning of the blank space using “parol” or external evidence in the tenant’s favor. And that can end up costing you big bucks.

Object Quickly If a Tenant Makes a Renewal Mistake

Sep 27, 2023

If a tenant exercises a renewal option without following all the procedures or requirements set out in the renewal clause, object right away. Failure to speak now may mean that you’ll forever have to hold your peace.
