Tips for commercial leasing

[Nick Fitzpatrick]

My family has a smaller office space building in northern California (Healdsburg if anyone is looking for some office space!) and one of the long term tenants is moving out in a few months. I still have not reviewed other leases to see if they are structured as a gross or triple net but was wondering in anyone in here had links to some easy DIY templates for commercial leases or should I only attempt to do this through an attorney or professional property manager. I have some experience leasing my residential units but this seems like a different challenge I would like to help them out but want to make sure I keep them protected and represent them well. Any advice would be greatly appreciated!
