Refinance investment property with no mortgage (properties, rental, loan, investing)

[SHMEKY1967]

We are into investing and have a few rental properties. We are looking to purchase another property and instead of using our "own money", we have a 2unit property that we have paid off and was thinking maybe using the equity from this property for down payment. Is this even possible? I don't think that you can do a equity loan on rental property, but can you refinance if there is no mortgage on it? I was thinking of the "write off" too... Any suggestions?
