Investor thinking of getting a Real Estate License in PA

[Edward Shen]

Hi everyone, I live in PA and is trying to invest into real estate to flip or rent like most investors are doing... However I feel that i had been running into trouble in getting to view houses in time with a realtor and making a offer before the house is already under contract. Plus i was thinking that I can save or earn the commission for buying and selling my own House. I have two questions:

1) What are the pros and cons of having a real estate license as a investor.

2) What is the fastest and best way to getting your PA real estate license. I will most likely need to take it online on my own pace due to work. 

Thank you!
