Hello Lian, welcome to BP! I'm a new investor myself and I'm in the same boat that you are. As both James and Preston have mentioned above, the podcasts are a great way to start building your knowledge. There are also some local meet ups in the Tulsa area. There is one group that is coordinated on BP, however, it is not sponsored by BP. The link for the last meet-up, which has already passed, is below:

There is also a Tulsa area REIA (Real Estate Investment Association) that meets up the second Thursday of each month, but they have various meetings throughout the month. You can find more information on them in the link below:

They also have a monthly landlord luncheon that you can find at the link below:

I have attended one local REIA meeting and found it extremely informative. They had a speaker from Denver talk on contracts with contractors. They also provide ample time to meet with other investors to network. I have not attended the luncheon, but plan to soon.
I found out at the last meeting that the "host" on the page has recently passed, and the new "host" does not have access to the website to update any changes. I only bring this up because the address was changed the last time I went. The new "host" posted the new location in the comments section, his name was Robert. So pay attention to the comments to be sure that you are up to date on any changes that may occur. The link says that there is a $20 fee, but that is waved for first time visitors. However, I didn't notice anyone collecting dues, so that may have changed as well.
I'll end by saying that there is a ton of information that can be attained from BP. The forums, podcasts, webinars, and blogs have so much information that can be utilized. From my brief experience everyone is extremely helpful. So don't limit your interaction to the local area. There is a ton of knowledge that can be found on this website as well.
Good luck to you!
