How can I expand this by leveraging my assets?

[Alan Eng]

Hi,

I currently own 3 properties. 

2 are full paid off and are being rented. Total net worth about $800k.

Rent per month: $3150

1 owner occupied property with a lien of about $188K.

How can i use my properties to secure loans to purchase more property? I tried to take out a HELOC but my units have too many rentals and did not qualify from a bank.

Would I have the same difficulty if i tried to do a Cash Out refinance on one of the properties? 

Thank for your comments in advance!
