Finding a portfolio of properties

[Kush Khandelwal]

My goal is to acquire about 5-10 properties in the next 1 year. Given the time /effort in finding each property and all the paperwork required, somebody suggested acquiring a portfolio. Seems to make sense as I've a full time plus job right now and could use any economies of scale I can find. 

Any suggestions on where to go looking for one? I see some on Roofstock but wondering if there are other leads out there?
