I work at a medium-sized wholesaling company and comp off-market deals 24/7, so I can speak for Propstream as a non MLS User with 3 years of experience on the platform. 

How can I use this platform to learn?

Attend local investor meetups, join local Real Estate Investment Associations (REIAs), join digital groups like LinkedIn and Facebook, and use platforms like BiggerPockets to connect with experienced investors, contractors, and potential partners.

I will say the Facebook groups and reversing different platforms have been the most successful.

But ensure it is legit, if you are audited, and you didn't rightfully take the position, it's not just the tax - you'll be hit with late payment penalties, substantial underpayment penalties, interest, and potentially fraud related penalties if it can be determined that you knew you didn't meet the qualifications but claimed it anyways. 

You've landed in the perfect platform to kickstart your learning journey.

My personal soapbox statement - Airbnb is an abusive spouse that slowly people are waking up to realize they are in a controling abusive relationship and they start to develop an escape plan (more platforms/direct website) so they are no longer relying on Airbnb.

Through relentless self-education on platforms like BiggerPockets, networking like crazy (over 200 Zoom calls in 2020!)

If income, expenses, and comps look legit, I'm thinking about $160 and hoping I can land it somewhere around $175K.

You should utilize resources like BiggerPockets, build a team, and use online platforms to find potential properties.
