There are several good reasons to appeal the property tax assessments of your NNN leased real estate investments. Tax appeals have these advantages. Plan your appeal to avoid taxation of tenant improvements. Many tax appraisers use the cost approach which may include interior tenant improvements - some of which may have been installed by your tenant. Obtaining lower tax appraisals will lower your cost of holding a vacant space until a new tenant is found. By obtaining lower tax appraisals, you help your tenant by lowering thier cost of taxes through out the year. This builds tenant goodwill. Lower tax appraisals assist you in achieving higher base net lease term rental rates. This makes your property more competitive in the market when lease incentives are needed to get that sought after tenant.
