3/3 properties What could I do next?

[Kash Chau]

Hi,

I am hoping to gain some insight into what my next steps should be.

Currently I own 3 rental properties 3 units each (all in CT), with good cash flow.  I do most of the management myself.  I have 25% down on each one.  Currently I have three different loans.

My questions are: 

how do I keep growing?  

Should I continue to invest in 3-4 family residential families units?  Or should I start looking into trading up? 

Is it possible for me to roll all my property loans into one?

Is it possible to get a LOC on the properties, then use the credit line to fund the next purchase?

Thank you in advance
