Virtual Assistants for cold calling

[Jonathan Martinez]

Hello BiggerPocketeers, 

I received a cold call from a virtual assistant (in the Philippines) regarding lead generation for someone else. I started a quick conversation asking her I may be interested in looking to hire a virtual assistant for similar work. She mentioned she was very interested and we scheduled a call for the week.

I wanted to find out a general experience from BiggerPockets members working with virtual assistants. Some questions I have are: Would you recommend it for investors/ agents? What is an average pay rate? Some good and bad experiences, pitfalls to avoid. 

Thanks in advance!
