Tenants for retail tenants try to impose non-cummulative caps on cam, management, etc.

Also set up some keywords that revolve around that subject, and you'll be alerted when people mention it.  

Cam

We stay away from onerous lease terms on the landlord with a NN lease.The reimbursement is more for retail strip centers NNN where you have base rent per ft and then CAM.

It's a revolving line of credit so you only start paying when you are actually using the line.

Property management is key to reading leases since commercial leases can be very complicated with CAM's and who is responsible for what.

The HELOC provides a great opportunity to give you that revolving working capital, but will come at a higher interest rate than say a 30 year mortgage would. 

I found a handful of local banks that will do an revolving line of credit on investment properties.

You could do a cashout Refi, and get a lump sum out right away, or you could looking into getting a HELOC on the investment properties which would give you a revolving line of credit that you could reuse for numerous purposes.

It all revolves around cash in VS cash out.
