Requesting advice for lending against a rental portfolio

[Travis Salley]

BP, I own three single family homes that are leased out to medical companies. 2 are assisted living businesses and the third is a transition home clinic. The portfolio yields 18k a month. I would like to refinance so I can use some equity to expand. Do you know of any lending company that would lend on this type of portfolio? I have not had much like calling around.
