How can Refi with a high DTI?

[Frank Rizzo]

I am a buy and hold investor. Over the past 2 years I have acquired 9 units/4 properties. My primary residence is a single family with 2 rental cottages on the property. I added a lot of value to it and would like to do a cash out refi or get a heloc. The problem I am having is my DTI. The more properties I have the higher the debt. Even with them all cash flowing, the DTI goes up with every property. I understand that i may be hitting the end of the line with getting personal loans. The question is how can i get personal financing to do a cash out refi with a DTI of 55%? Any imput is much appreciated?
