Hi @Hai Le this site might be a good place to start.

Are there mid term rental sites to find them?   

Hello BiggerPockets,I am new to the site and very interested in diving into the enormous amount of material on the site. 

@Jonathan Tirado at least 90% of the RE investors on this site have full-time jobs!

Hello Hunter, does your local MLS not allow you to syndicate your rental listing to all those site? 

Prior to the 3-day workshop (3 weeks before) they gave us access to the portal on their site where we could prepare and learn a little bit about what we were going to be learning in person, also questions to get to know us better and our goals.

I have looked at sites like Realtor.com, Redfin, and Zillow but it doesn't provide OR doesn't give a pinpoint sale price on properties.

It is one of the reason they continue to be popular despite the outrageous fees in my opinion. 

These sites are a complete waste of time and money.
