Best Form of Back Financing

[James Pollock]

Looking for advice on the best form(s) of bank financing. I have typically been getting commercial loans with a 20 year amortization at up to 80% loan to value. This works fairly well when it comes to holding the properties over time but I have found it to be a little inflexible when it comes to utilitizing any of the equity in the properties. For example, if I have 5 properties on a loan that have worked down to a 65% LTV, there are no easy ways for me to borrow some of my equity up to 80% LTV to invest in another property.

Has anyone had success with using Lines of Credit for not only the initial purchase of the property but also holding it for the longer term?  My thought is that if I had a revolving line (rather than an installment mortgage) I may be able to tap into my equity more easily.
