Buying note on Oklahoma home, FC in process

I'm evaluating the purchase of a first position NPL on a decent home in Tulsa OK and the current noteholder has started foreclosure. I'm still digging around with the seller, but have not much knowledge of OK other than it is a judicial state with approx. 185 days timeline. 

Does anyone have any experience in OK with foreclosures and/or can offer any insight as to what I should be looking out for other than the usual FC process?

Thanks, Bob
