But there are so many different courses to choose from as well as different mentors.Would you guys mind sharing which online courses you think are top notch as well as which mentors you would choose to work with if you could?

Door knocking, driving for dollars, direct mail, creating a thought leadership platform and a landing page, "we buy houses" flyers, bandit signs, etc., calling rental listings on Zillow, Craigslist, etc., wholesalers, meetup groups (either attending or creating your own).

I have seen mixed reviews for CoStar and cant find pricing anywhere online.

Also, is online banking a viable alternative?

Furthermore I want to get a detailed blueprint of how wholesaling works as far as generating leads(best platform to find leads).

You need to look online to see if Tulsa has a zoning tool for you to verify or you can go in to the planning department and ask questions.

It's currently being renovated and I know that they're putting in some commercial, but I don't know what they're doing for residential and I cant find any specifics online.  

Once you narrow down the city and the prices you want to invest in you can go to every city and find an online rei group and email questions to local realtors, property managers, investors. you can email me as I will have 2 off market buy and hold houses very soon in the 200k range.

I'm wondering if there are any good platforms out there that are free (that offer real estate books and not just "classics").

Also drive the neighborhoods look for abandoned houses write down the addresses go online to Harrison County tax accessors website and see where the owner lives.
